IPC: G02F1/133
Filed: 1993-03-25
Abstract: PURPOSE:To reduce the changing ratio of impressed voltage and transmissivity and to prevent a picture frame-shaped area from being generated at the outer peirpheral part of the liquid crystal device by respectively setting the twisted helical angle of a liquid crystal molecule, the product of the thickness of a liquid crystal layer and the refractive index anisatropy of liquid crystal within a specified range. CONSTITUTION:The product of the thickness (mum) of the liquid crystal layer and the refractive index anisotropy of liquid crystal is settled within the range from 0.6 to 0.7mum, and an angle 13c formed by an orientating direction 12a of the orientation film of an upper substrate and an orientating direction 12b of the orientation film of a lower substrate, namely, the twisted helical angle of liquid crystal is settled within the range from 100 deg. to 120 deg.. On the other hand, the amount of optical active materials to be added is decided so that the surface accuracy of the substrate can be within 0.1mum and the level of a ratio between layer thickness (d) of liquid crystal and torsional pitch (p) of the liquid crystal molecule can be turned to 0.25<d/p<0.40. Further, an angle 13a formed by the transmission axis or absorption axis of an upper light polarizing plane and the orientating direction of the orientation film of the lower substrate is 10 deg. and an angle 13b formed by the transmission axis or absorption axis of a lower polarizing plane and the orientating direction of the orientation film of the upper substrate is 10 deg..

Title: Antiskid controlling device
Inventor: MAEHARA TOSHIFUMI
IPC: B60T8/1761
Filed: 1981-05-02
Abstract: PURPOSE:To reduce the number of solenoid valves neccessary for operation to only one  and make various setting of liquid pressure recovery characteristics possible by changing a return spring by a structure wherein a valve equipped between a decompression controlling liquid pressure chamber and a reservoir is controlled by means of electromagnetic solenoid and a reservoir piston is pressed by means of a return spring. CONSTITUTION:A normally closed check valve 13 and a decompression piston 15 are  provided between an input port 19 and an output port 20. The decompression controlling chamber c, which is normally sealed by means of a normally closed check valve  26, is formed at the opposite side of the decompression piston 15. When a wheel locks, the valve 26 is open by means of the armature 25 of the solenoid 23, resulting in escaping the liquid in the chamber c into a reservoir d. As a result, the decompression piston 15 is moved so as to reduce the braking effort. A plunger 37, which is actuated by an  eccentric cam 36 rotating together with the wheel, recovers the braking effort by pressurizing the liquid in the reservoir d and pushing it back into the chamber c. Owing to  the structure as described above, only one solenoid valve is necessary enough for operation and as well as various recovery characteristics can be set by changing the spring 34 of the reservoir d.

Title: Heating device and image forming device provided therewith
Inventor: TAKADA SHINICHI
IPC: G03G21/14
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of the temperature control of a heating resistor by selecting one frequency of waveform having a specified cycle in accordance with detected temperature by a temperature detecting body from plural frequencies set previously and controlling the switching of a switching means over the cycle of the selected frequency. SOLUTION: When a control part 3 receives a temperature control starting instruction, it initializes (high temperature control accuracy is required) a flag for switching the frequency to decide control frequency to '1', and the timer for switching the frequency is reset to '0'. Next, after calculating the difference between the temperature of the heating resistor 1 detected by a thermistor 2 and a target controlled temperature, the control part 3 decides feed duty based on the comparison of an error component with previously set data. The data to output the previously calculated feed duty is set according to the frequency flag, such as, at the 1st frequency when the flag for switching the frequency is '0' (high temperature control accuracy is not required), and at the second frequency higher than the 1st frequency when the frequency flag is '1'.

Title: Pipeline computer
Inventor: SUZAKU JIROU
IPC: G06F9/318
Filed: 1982-04-22
Abstract: PURPOSE:To accelerate the restart of decoding of an instruction following a branch instruction, by releasing the inhibition of decoding by the branch instruction when there is no store type instruction. CONSTITUTION:A decoding inhibition tag is inputted as it is to the next stage only when a signal 21 is logic ''1''. When, however, the logic of the signal 21 is ''0'', it is inhibited by AND gates 22, 23, and 24 and the decoding inhibition tag is deleted at the next stage. For example, when only a tag ST14(19) has logic ''1'' and the decoding inhibition tag DCI0(6) also is logic ''1'', logic ''1'' is inputted to a DCI1(7), but the execution of an IS(4) ends and the output signal 21 of an OR gate 20 goes to logic [0]. Then, the output of an OR gate 11 goes to logic [0], so an instruction and data are prefetched from a branch destination address unless the signal 12 has logic ''1'' even if the deciding inhibition is released and the DCI0(6) is logic ''1'' to indicate a store instruction.

Filed: 1984-04-05
Abstract: PURPOSE:To achieve a measurement with a high accuracy and a high operability by a method wherein a parallel beam flux is made incident on an objective lens to be inspected, the emission light is admitted into an optical means whose incident surface coincides with the focal plane at the focus of the objective lens on an object and the scattered light is detected to display the numerical aperture. CONSTITUTION:Beam from a laser 33 is turned to a parallel beam flux with a beam expander 35 and is made incident on an objective lens 32 to be inspected passing through an eyepiece lens 31. The emission light from the lens 32 is made incident on a glass body 38 whose incident surface coincides with the focal plane at the focus of the lens 32 on an object. The emission light scatters inside the glass body 38 and is detected with a quantity-of-light detecting element 40 through a slit 39. The slit 39 and the element 40 reciprocate along the circumferential surface of the glass body 38 and output of the element 40 is inputted into a pulse counter 41 to count the number of pulses per one reciprocation while the results are converted to a numerical aperture value, which is inputted into a main display 42 to show the numerical aperture. Thus, the numerical aperture can be measured with a high accuracy and a high operability without being affected by external light.

Title: Modulation device
Inventor: SATO HIDEAKI
IPC: H03C7/02
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a small and inexpensive reflection-type modulator in a high frequency with simplified constitution by constituting a modulation part with a diode which is provided near a matching part, a signal source controlling the bias of the diode and resistance for consuming the detection output of the diode and exchanging heat. SOLUTION: The diode 3 becomes a conduction state in a state where the detection diode 3 receives positive bias and it operates as a detector. When the diode 3 is zero bias or inverse bias, the diode 3 becomes a cut off state and the matching of a waveguide 1 and the detection circuit is destroyed. The quantity of reflection waves returning to the waveguide 1 is controlled by the bias state of the diode 3 and the waves inputted to the waveguide 1 reflect. Then, they return to the waveguide 1. At the time of output, the input signal is modulated by the output signal voltage of the signal source 4. Thus, an input milliwave is heated by resistance 6 in a state where the detection diode 3 is biased to be positive and reflection is suppressed.
