Title: Position detector
Inventor: IMAI YASUAKI
IPC: G11B7/09
Filed: 1987-06-30
Abstract: PURPOSE:To perform accurate position detection by arranging a measuring means which measures the relative position of a holding member in its moving direction at a specific position. CONSTITUTION:An objective 10 is positioned above the center position C of the objective holding member 8 at a distance ly in a (y) direction. Then a photoreflector main body 28 and a photoreflector reflecting plate 32 are arranged above the center position C of the objective holding member 8 at the distance ly in the (y) direction. Further, the photoreflector reflecting plate 32 is positioned at a distance lx from the center position C of the objective holding member 8 in an (x) direction. If rolling occurs at the time of driving the objective holding member 8, an objective 10 shifts in (x)-directional position by a specific distance, but the photoreflector reflecting plate 32 also moves in the same (x) direction by the same distance, so the (x)-directional position of the objective 10 is accurately detected.

Title: Pulse doppler diagnostic apparatus
Inventor: TAKEUCHI YASUTO
IPC: A61B8/06
Filed: 1987-06-30
Abstract: PURPOSE:To easily determine an anatomical position where there is Doppler shift, by separating a receiving signal into a B-mode signal and a Doppler signal and successively applying MTI processing and signal processing for specific display to the Doppler signal to perform the specific display on the cursor of a picture. CONSTITUTION:The ultrasonic wave reflected from an examinee is received by an ultrasonic probe 1 and amplified by a receiver 2. The output of this receiver 2 is amplified and detected in one route by an amplifying and detecting circuit 3 to become a B-mode video signal which is, in turn, converted to a digital signal in an AD converter 4. In the other route, the receiving signal is inputted to an MTI processing circuit 5 to erase the reflected wave from a fixed substance to be converted to an MTI video signal only composed of the reflected wave from a moving substance and said video signal is converted to a digital signal by an AD converter 6 to be inputted to a section specific signal processing part 7. The output of the AD converter 4 and that of the section specific signal processing part 7 are simultaneously written in the frame memory of a DSC 8 and displayed on a display apparatus 9. By this method, sensitivity can be well confirmed visually while an anatomical position where Doppler shift is present is made clear.

Title: Color picture tube
Inventor: SUETSUGU HIROSHI
IPC: H01J29/07
Filed: 1985-07-23
Abstract: PURPOSE:To enable formation of dense dots on the face panel when forming a fluorescent screen by bending the shadowmask side end section of frame into C-shape to the tube axis side. CONSTITUTION:One end of spring 3 will fit in a panel pin 2 burried in the face plate 1 through panel pin fitting hole of spring while the other end is welded to one end of bimetal supporting member 4. The other end of bimetal supporting member 4 and the shadowmask 6 are welded to the frame 5 to bend the shadowmask side end section 5a of frame 5 into C-shape to the tube axis side thus to increase the mechanical strength of frame. With such shadowmask supporting structure, the frame will never deform even upon assembling of frame into a jig when assembling the frame mask thus to enable accurate positioning of the distance of plane passing through the center of fitting holes of three springs and the curved face of shadowmask. Consequently, the dots can be arranged densely onto the face panel when forming the fluorescent face.

Title: Choke for carburetor
Inventor: SAGAWA MASAFUMI
IPC: F02M1/02
Filed: 1986-07-11
Abstract: PURPOSE:To make a manual type choke valve possible to be opened and released automatically, by pressing a choke main valve forcedly by the stopper installed in a choke subvalve and opening it at a time when this choke subvalve is opened by suction pressure in a suction passage. CONSTITUTION:When a choke valve 14 is manually closed, a subvalve 26 constituting this choke valve 14 is being extended on almost the same surface with a main valve 24. And, when a throttle valve 16 is opened and an engine is started, the subvalve 26 is rotated in the opening direction against energizing force of a coil spring 34 by dint of suction pressure acting on the inside of a suction passage 12. In consequence, a stopper 36 solidly installed in a branch part 32 of the subvalve 26 comes into contact with the back of the main valve 24, pressing the main valve 24 solidly with rotation of the subvalve 26 and making the main valve 24 rotate in the opening direction. Therefore, even in case of the manual type choke valve 14, the choke valve 14 can be opened automatically after engine starting, thus it can meet obliviousness in release of a choke state by a driver.

Title: Electrifying device for electrophotography
Inventor: SHINOHARA SHINJI
IPC: G03G15/02
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To prevent the characteristic of a photoreceptor drum from being damaged by impressing a high voltage on an electrifier by using a one-shot multivibrator actuated when the rotation of the photoreceptor is detected. SOLUTION: When the photoreceptor drum 1 is started to be rotated, the notch of a rotary disk 17 is detected by a rotation detection sensor 18 and a pulse-like signal 18a is transmitted to the one-shot multivibrator 19. Since the fixed rotational speed of the drum 1 is kept, the signal 18a becomes the continuity of pulses having a fixed cycle. By the vibrator 19, a duration signal 19a is transmitted to a high voltage generator 12 from the rising time of the waveform of the signal 18a. At this time, the signal 19a is apparently continuously outputted by the vibrator 19 while the signal 18a continuously exists. Therefore, the high voltage is impressed on the electrifier 2 by the generator 12 by the continuous output of the signal 19a from the vibrator 19.

Title: Wireless manual encoder
Inventor: KANDA KUNIO
IPC: G08C17/00
Filed: 1989-06-28
Abstract: PURPOSE:To simplify a construction without using a cable, by preparing pulse trains different in a time of continuation and by modulating a carrier wave of single frequency by these pulse trains. CONSTITUTION:Based on waves of phase A and phase B outputted by a manual encoder 1, a waveform detecting circuit 2 identifies whether the direction of rotation thereof is forward or reverse, and based on the result of discrimination, outputs two kinds of rectangular waves, an alpha wave and a beta wave, which have two kinds of pulse widths set beforehand. A modulation circuit 3 modulates a normal rotation signal wave (the alpha wave) and a reverse rotation signal wave (the beta wave) outputted by the circuit 2. Subsequently, these signals are amplified 5 and sent to an antenna 5 for transmission. Since the alpha wave and the beta wave are not transmitted simultaneously, a line connecting the circuit 2 with the circuit 3 is constructed of one circuit without any hindrance.
