Title: Image pickup device
Inventor: OGIKUBO KAZUHIRO
IPC: G01J1/00
Filed: 1990-06-15
Abstract: PURPOSE:To obtain the image pickup device which eliminates the need to replace a reference light source for a long period while calibrated optically in a short time by putting two electronic shutters in operation synchronously with an external control voltage. CONSTITUTION:When the control voltage applied to the electronic shutters 5 and 6 is set to 0 in a state wherein an object is observed, vertical polarized incident light and horizontal polarized incident light from the object are both transmitted through an electronic shutter 5 and made incident on an image pickup element 2. Calibration light from the reference light source 3, however, is cut off by the electronic shutter 6 even when the reference light source 3 is turned on at all times, so the light never exits from a calibration light projection part 4 and an image of the object can be picked up. When the control voltage synchronized with the electronic shutters 5 and 6 is applied from outside, both the electronic shutters 5 and 6 transmit only light containing the vertical polarized wave. Consequently, only the calibration light which contains the vertical polarized wave from the reference light source 3 and light containing the vertical polarized light from the observation object are made incident on the image pickup element 2 to enable the optical calibration.

Title: Vibration-type compressor
Inventor: FUJIYAMA CHIKAHIDE
IPC: F25B9/14
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To suppress vibration caused by the inconsistency of the resonance frequency of a movable part and at the same time to reduce the vibration being transferred to a compressor by connecting both movable parts or the movable parts to their move-absorbing equipment by an elastic member. SOLUTION: When AC with a specific frequency is supplied to each linear motor 15, each movable part 20 is reciprocated against a fixing part with a cycle being determined, for example, by the spring constant of an elastic member 25 and a gas is periodically compressed in the compression space in a cylinder 3. At that time, a pair of movable parts 20 is connected each other by the elastic member 25 being shared with the both movable parts thus equally influencing the both movable parts even if the spring constant varies due to a solid difference in the elastic member 25. Therefore, the inconsistency state in the resonance frequency of the both movable parts 20 that is caused by a case where each movable part 20 is independently supported by the elastic member 25 is eliminated and the generation of vibration is suppressed, thus effectively reducing the vibration of a compressor A.

Title: Piston for internal combustion engine
Inventor: GOTOU TOORU
IPC: F02F3/02
Filed: 1980-11-10
Abstract: PURPOSE:To reduce knocking noise of the piston in such a way that in the outer periphery of a piston in an internal combustion engine, part on the anti-thrust side which contacts the wall face of a cylinder when it is in compression stroke at least is notched slantwise as it comes near to its axial line toward the upper part of the piston. CONSTITUTION:A piston (a) is conically formed from the skirt part (a2) of the lower part toward a ring land part (a1), and an exhaust port 2 and an air inlet port 3 are opened toward the inner wall face in a cylinder b. In the piston (a), part on its anti-thrust side S2 is notched slantwise as it comes near to its axial line l2 toward the upper part of the piston. This notched part (a2) is faced opposite to the exhaust port 2 at the time of top dead point, and formed over the length extent between its upper side and lower side. In consequence, the angle alpha to the axial line l2 of the cylinder for the piston becomes larger, and when it is transferred to expansion stroke, it clashes from the lowest part of the skirt part (a2) which is thin and less rigid to the cylinder wall face, and knocking noise is reduced.

Title: Limiter circuit
Inventor: YAMAMOTO TAKESHI
IPC: H01L21/8238
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a limiter circuit to realize a high gain equivalent to that of a bipolar with a CMOS circuit with a comparatively small element size. SOLUTION: Differential circuits are constituted of PMOS transistors M1, M2. Drain current of the transistor M1 is inverted by NMOS transistors M3, M5, is added to drain current of the transistor M2 and increase/decrease of the current is promoted. The drain current is further inverted by NMOS transistors M4, M6 and is fed back to the drain current of the transistor M1. The drain current of the transistor M2 is similarly fed back to the drain current of the transistor M2. Thus, large positive feedback is mutually performed to outputted differential currents of the differential circuit and operation approximated to switching is performed by a load circuit to be constituted of the transistors M3 to M6 according to high or low relation between the drain currents of the transistors M1, M2. Thus, the limiter circuit with high gain is realized only by a comparatively small CMOS element.
