Title: Solid-state image sensing device
Inventor: MIYATAKE SHIGEHIRO
IPC: H04N5/341
Filed: 1989-12-21
Abstract: PURPOSE:To obtain a solid-state image sensing device which is wide in dynamic range and able to accurately pickup the image of an object which ranges from a high to a low brightness by a method wherein a photocurrent is logarithmically, compressedly converted through a MOS transistor by the use of its sub-threshold current characteristics. CONSTITUTION:A solid-state image sensing device is composed of a light sensing means 1 which is able to generate a photocurrent corresponding to the volume of incident light, a MOS transistor 2a to which a photocurrent is inputted, and a bias means VSUB which biases the MOS transistor 2a so as to enable a sub-threshold current to flow through the transistor 2a with a voltage of a threshold value or below, where the MOS transistor 2a logarithmically, compressedly converts a photocurrent through its sub-threshold current characteristics. Therefore, signal charge is compressed into a logarithmic value of the incident light amount at a photoelectric conversion section, whereby the signal charge previously becomes a small amount of charge and serves as an output signal through a signal transfer section. By this setup, a solid-state image sensing device of this design can accurately pick up the image of a subject which ranges from a high to a low brightness independent of the influence of the dynamic range of a signal transfer section.

Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a pair of binoculars with photographing function capable of performing the focusing of a photographing optical system based on the positional information of an optical member for the focusing of an observation optical system. SOLUTION: The position of a first optical member 4 performing the focusing by being displaced in the optical axis A1 direction of the observation optical system A is detected by a detecting means 11. A second optical member performing the focusing by being displaced in the optical axis B1 direction of the photographing optical system B is displaced based on the positional information of the member 4, so that the focusing of the system B can be performed. In this case, a system control CPU 47 stores so-called climbing AF system data in a memory by which the definition of an image plane is detected by the video signal of an object, a focusing lens is searched at a position becoming a peak showing the definition, and focusing is performed, for example, as a system which becomes a base for reflecting calculated information to the focusing of the system B.  The calculated information is used in order to perform the search of the focusing lens 6a in an adequately limited(controlled) range.

IPC: A61H1/00
Filed: 1992-11-20
Abstract: PURPOSE:To transmit statically an impact to a diseased part and to cure it without transmitting direct vibration to the outside except an apparatus by fixing a self-supporting one shot electromagnetic plunger in the downward direction in a heavy housing case wherein a contactor is formed at the apex toward the outside and a cylindrical insert is formed toward the inside. CONSTITUTION:When an electric input is applied to a plunger coil 15 of a self-supporting type one shot electromagnetic plunger 4, an electromagnet is oxidized and a movable core 5a of a movable element 5 of the plunger 4 is attracted by a fixed core 5b and is pressed downward by an impact force by overcoming the upward elastic force of an energizing apparatus and a movable frame 6 presses a repeating element 8. Then, a coil spring 9 in a blind hole 8b of the repeating element 8 is pushed and compressed to transmit the impact force to the insert 2 and furthermore, it is converted and transmitted to a contactor 1 molded integrally at the apex of the housing case 3 as a static pressure.

Title: Clinical radiation thermometer
Inventor: MINAMI SHIGETOSHI
IPC: A61B5/00
Filed: 1993-12-28
Abstract: PURPOSE:To accurately measure body temperature with a simple construction by providing a control means to control whether the body temperature is measured or not with an infrared sensor based on a signal to be detected by light sensors. CONSTITUTION:An infrared sensor 2 is provided inside a probe 1 to detect infrared rays to be radiated from an eardrum. Two windows 4a and 4b, upper and lower, are arranged at positions where the probe 1 is hidden in the hole of the ear when it is inserted sufficiently into the aural hole and visible light sensors 3a and 3b are disposed inside the respective windows. When a visible light exceeding a fixed level is detected by the visible light sensors 3 and 3b, the measurement of body temperature is not performed by judging that the probe 1 is not inserted sufficiently into the aural hole. When the visible light is little detected by the visible light sensors 3a and 3b, the measurement of the body temperature is started by judging that the probe is inserted sufficiently into the aural hole. Thus, it enables detection to determine whether or not the probe 1 is inserted sufficiently into the aural hole.

Title: Removal of suspended impurities with mixing floor type filter/desalter
Inventor: OTANI TAKU
IPC: G21F9/12
Filed: 1987-12-29
Abstract: PURPOSE:To enable sufficient removal of a clad, by forming a resin floor with the degree of crosslinking of anion and cation exchange resins reduced to 7.5-3% in terms of the content of divinyl benzene to remove suspended impurities during the processing of a primary cooling water of a BWR type nuclear power generation plant. CONSTITUTION:A mixing floor is formed from a resin with the degree of crosslinking of cation and anion exchange resins reduced 7.5-3% in terms of the content of divinyl benzene to remove suspended impurities during the processing of a primary cooling water of a BWR type nuclear power generation plant. The degree of crosslinking is so low in the anion and cation exchange resins herein used to make the diffusion rate of a clad higher in a resin particle with a relatively large pores therein. The resin is elastic, not being comparatively hard. This allows a large clad adsorbing effect due to an elastic deformation of the surface of a resin during passage through water, thereby enabling production of a highly pure water with a low density of the clad in filtering and desalting operations.

Title: Compact motor
Inventor: TANAKA TAKESHI
IPC: H02K13/00
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To reliably prevent noise by forming an inclined shape where the front end part of a first resistance part is brought into contact with a commutator before wearing a brush contact surface for wearing due to the progress of brush wearing and hence gradually reaching the contact of an entire surface. SOLUTION: A brush 10 is an inclined double-layer brush, and is provided with a first resistance part 101 that is formed gradually narrower towered the rear side from the front side in the rotary direction of a commutator 3 and a second resistance part 102 that is formed gradually wider toward the rear side. Then, when the brush 10 is rotated, the contact surface of the brush 10, a tip corner 1 of the first resistance part 101 is brought into contact with a first segment of the commutator at the initial stage for the contact surface of the brush 10, and a triangular slide surface that is gradually thinned toward the rear is slid to a rear end corner 2. Further, wearing of the brush 10 proceeds and the tip corners 1 and 3 touch the commutator, thus spreading a slide zone to the second resistance part 102.  After that, wearing proceeds further, thus resulting in entire surface sliding and hence reducing vibration and electromagnetic noise.

Title: Vehicular steering control device
Inventor: KOSHIRO TAKAHIRO
IPC: B62D5/04
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To solve the problem that when the driving motor of a transmission ratio varying mechanism is stopped near a maximum steering angle, motor heating due to increase in load is inhibited but a transmission ratio varies abruptly as the result of the stop of the driving motor, making the driver feel disagreeable. SOLUTION: Near the maximum steering angle where a wheel steering angle exceeds a threshold, a control signal Is (in) normally set for the driving motor is limited to such an extent that the transmission ratio varying mechanism can be kept immobile by the action of friction torque which the transmission ratio varying mechanism itself has. The driving motor is actuated by the limited control signal Is (out).
