Title: Footrest of wheelechair
Inventor: KANEKO MITSURU
IPC: A61G5/04
Filed: 1987-11-06
Abstract: PURPOSE:To easily detach a footrest to rotate the same left and right, by rotating a footrest main body upwardly while pressing a push-up rod downwardly by a cam surface and raising the footrest main body by the repulsive force of said rod to release the prescription of rotation due to a stopper pin. CONSTITUTION:When a footrest 9 is detached from a wheelchair main body or rotated left and right, a footrest main body 11 is held to be rotated. The cam surface of the rear end of the footrest 9 is slid with the cam surface 22 of the upper surface of a push-up rod 21 to press the push-up rod 21 downwardly. Since the push-up rod 21 is prescribed in its downward movement by a stopper pin 16, a footrest shaft 15 receives the repulsive force of said rod 21 to relatively move upwardly. When the taper groove 20 provided to the lower end of the footrest shaft 15 rises to a position where the stopper pin 16 is not hooked, the footrest 9 can be easily rotated left and right. If the footrest main body 11 is raised upwardly even when the footrest 9 is detached, no moment is generated in the footrest shaft 14 and the footrest can be easily pulled out.

Title: Mr imaging system
Inventor: OHARA HIROSHI
IPC: A61B5/055
Filed: 1991-09-30
Abstract: PURPOSE:To prevent an artifact caused by movement of the testee from generation by adding successively a dephase pulse and a rephase pulse based on an inclined magnetic filed in an arbitrary unidirection and generating a resonance signal wherein only a positional information is encoded. CONSTITUTION:For example, in a field echo method, a pulse of an inclined magnetic field Gy which can deny the influence of the inclined magnetic field Gy for a phase encode is added and the phase for magnetization is arranged again and the second echo signal is generated by making a Gx pulse turn back. This pulse sequence is repeated while the magnitude of the inclined magnetic field Gy for the phase encode is changed. As in the data collected from the second echo signal, only frequency is encoded and only a positional information in the X direction of a selected slice face is encoded, if this data is Fourier- transformed, a one dimensional image obtd. by projecting the selected slice face on one axis in the X direction is obtd. and movement of the testee can be found thereby.

Title: Negative pressure control valve
Inventor: HASEGAWA MIKINOBU
IPC: F16K7/17
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and assembly man-hour of a float section and prevent resonance of the float section by constituting the float section in which a valve body is not provided internally and reducing its weight. SOLUTION: When negative pressure which is introduced through an input port 11 exceeds predetermined negative pressure, a diaphragm 18 is suctioned upward due to a difference in pressure against a difference in spring pressure of springs 21, 22, a valve body 23 comes into contact with a lower end of a projection pipe 20 together with a float section 19, and a section between the input port 11 and an output port 12 is shut off. At this time, if negative pressure is large, the diaphragm 18 and the float section 19 attempt to move upward further. Consequently, the valve body 23 leaves a valve seat 19b, atmospheric air pressure is introduced from an atmospheric air suction port 14 into a negative pressure chamber 16 side, and negative pressure is reduced instantaneously. As a result, the float section 19 moves downward.  If the above-mentioned operation is repeated, the valve body 23, the valve seat 19b, and the lower end of the projection pipe 20 are balanced in a condition in which they are in contact each other, and negative pressure which is larger than the predetermined negative pressure is not output from the output port 12.

Title: Voltage controlled oscillator and fm receiver incorporating this oscillator
Inventor: NODA MASAKI
IPC: H03K3/282
Filed: 1988-11-09
Abstract: PURPOSE:To simplify the adjustment of the extent of temperature compensation and to obtain a voltage controlled oscillator where the dependence of the oscillation frequency upon the temperature is reduced by providing a circuit which flows a current to the emitter of a current sucking transistor(TR) or branches and flows a current from the emitter and selecting the emitter resistance of the TR. CONSTITUTION:When a current forcibly flows to an emitter 101 of the current sucking TR or a current is branched and flows from the emitter 101 to the external, the control current of an oscillator 100 is changed; and it is necessary to change an emitter resistance 11 in accordance with the current value flowing to or out from the emitter 101 when the control current is returned to the original current value. Consequently, the current value flowing to or out from the emitter 101 and the emitter resistance 11 are selected to equivalently change the temperature coefficient of a temperature compensating circuit. Since temperature compensation of the oscillation frequency and adjustment of the extent of compensation are easily performed by the oscillating circuit and another DC circuit, the voltage controlled oscillator where the dependence of the oscillation frequency upon the temperature is reduced is obtained though it is made into an IC.

Title: Optical fine particle measuring apparatus
Inventor: ZAITSU YASUSHI
IPC: G01N15/14
Filed: 1988-11-08
Abstract: PURPOSE:To measure fine particles without causing lowering in grain size resolutions in a wide size range by projecting a measuring light to a flow cell made of a transparent material through which a fluid to be measured runs. CONSTITUTION:A first light receiving section 10 receives a transmission light 11 of a measuring light 6 transmitted through a flow cell 1 to output a first light reception signal 13a. A second light receiving section 16 receives a forward scattered light 17 caused by the irradiation of fine particles 2 in a fluid 3 to be measured in the flow cell 1 by the measuring light 6 and outputs a second light reception signal 19a corresponding to the results of light reception. A signal processing section 26 has signals 13a and 19a inputted thereinto and outputs a data signal 27 by a specified signal processing for the input signals. Then, since the signal 13a is a signal by a light shielding method while the signal 19a is a signal by a light scattering method, the number and a grain size distribution of the fine particles 2 can be measured by signals 15a and 15b with high grain size resolutions. This also enables measurement of the number and the grain size distribution of the fine particles 2 with high grain size resolutions by signals 24a and 24b.

Title: Horizontal deflecting circuit
Inventor: ONODERA YOSHIAKI
IPC: G09G1/16
Filed: 1987-11-07
Abstract: PURPOSE:To fix the lateral width of a display screen by constituting the respective power sources of a horizontal driving circuit and a horizontal output circuit to be a variable power source and always sending a most suitable driving condition to the horizontal output circuit regardless of used frequency. CONSTITUTION:When the frequency of a horizontal oscillation pulse is changed, the increase and decrease of driving current IB impressed on the base of the horizontal output transistor 5 of the horizontal output circuit 10 through the driving transformer 3 of the horizontal driving circuit 4 is adjusted by changing the voltage of the variable power source 17. Therefore, the output current IC of the horizontal output transistor 5 can be almost fixed regardless of the frequency. That means, the relation of the output current IC 1 and IC 2 can be made IC 1=IC 2 by making IB 1=IB 2 by increasing the driving current IB 1 by making supply voltage higher when the frequency is 15KHz and decreasing the driving current IB 2 by making the supply voltage lower when the frequency is 31KHz. Thus, the output change in the horizontal output circuit 10 can be controlled.

Title: High-side switch driving circuit
Inventor: AOYANAGI TAMIAKI
IPC: H03K17/687
Filed: 1990-10-22
Abstract: PURPOSE:To cut off a load simultaneously with the turning-off operation of a switch without being affected by the counter electromotive force of a coil by connecting a 2nd transistor(TR) between the gate and the source electrode of a 1st transistor(TR), and short-circuiting the gate and source of the 1st TR when the 1st TR turns off. CONSTITUTION:While an X terminal turns off, a Y terminal 8 turns on, so the 2nd TR 3 turns on and the gate electrode and source electrode of the 1st TR 2 are short-circuited, so that the 1st TR 2 turns off. Once the 1st TR 2 turns off, the current I of a coil 4 varies, so the counter electromotive force L.dI/dt is generated, but the gate and source of the 1st TR 2 are short-circuited by the 2nd TR 3, so even if a counter electromotive force is generated at the coil as the 1st TR turns off, the 1st TR is never biased reversely and, therefore, turns off fast.

Title: Parking assist device
Inventor: SUGIURA MASUO
IPC: H04N7/18
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a parking assist device capable of smooth image display without any time lag in the display even in the case that a currently available transmission medium of relatively low speed is used. SOLUTION: A garage 1 is provided with an image pickup camera 3 capable of image pickup of the parking position of a vehicle 11. The picked-up image is inputted into an information processing device 9, and only the image around the vehicle 11, for example, is taken out from the picked-up image to obtain taken-out information having a smaller amount of information than the one the picked-up image itself owns. The taken-out information is transmitted to the vehicle 11 through a transmission medium of relatively low speed like a public network for portable telephone, for example. The small amount of information can shorten transmission period, thus it is possible to display animated images smoothly on a display unit 15 positioned on the side of the vehicle 11.

Filed: 1987-11-10
Abstract: PURPOSE:To shorten the time for measurement by providing a Glan-Thompson prism, halfwave plate and quarter-wave plate supported rotatably with respect to the plane orthogonal with an optical axis between input side and output side optical fibers coupled to a lens. CONSTITUTION:The input side optical fiber 11 of a single mode is connected to a semiconductor laser and the output side optical fiber 21 of a single mode is connected to an optical power meter via a device to be measured (not shown in the figure). The Glan-Thompson prism 4 is formed by sticking two calcite prisms and is so adjusted that linearly polarized light is obtd. in the state of the largest optical power by aligning the main polarization axis and transmission polarization axis of a semiconductor laser. The halfwave plate 5 is capable of arbitrarily setting the main axis of polarization and projects the polarized light at the necessary polarization axis on the device to be measured when said plate is rotated. The quarter-wave plate 6 cancels the elliptical polarization of the polarized light by the double refraction which is generated by the local stress of the optical fiber 21. The P or S polarized light is thereby polarized to the linearly polarized light and is projected to a coupler which is the device to be measured.
