Title: Camera provided with auxiliary light device
Inventor: KATAOKA HIROYUKI
IPC: G02B7/28
Filed: 1990-02-05
Abstract: PURPOSE:To prevent wasteful power consumption caused by projecting auxiliary light thoughtlessly by providing an operation switch which allows an auxiliary light device not to act when a photographer decides that the auxiliary light is not necessitated. CONSTITUTION:A light emitting diode 46 is driven by a transistor Tr 45, and the base of the Tr 45 is connected to a microcomputer 10 through a switch 40 and a resistance 41. The auxiliary light device is constituted of the LED 46, the Tr 45 and a condensing lens 47. In the case that the brightness of an object is lower than a specified value when range-finding operation is performed based on the output from a sensor by an arithmetic operation circuit 17, the computer 10 generates the output to turn on the transistor 45 and to light the LED 46 and performs light projection in terms of pattern so that a range-finding action may be executed. When the photographer judges that the auxiliary light is not necessitated, the auxiliary light is not projected by turning off the operation switch 40.

Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To increase time of holding an interruptible gas quantity without increasing a cylinder diameter, length, or the like, prevent re-arcing, thus certainly make it interruptible and miniaturized by providing a cover body in which a gas blowout area of a gas outlet hole is enlarged due to movement of a cylinder in interruption direction. SOLUTION: A cylindrical cover body 14 supported by a cylinder 7 is positioned inside of a contact 9, an inner face comes into sliding contact with a first conductor 1, and a gas blowout area of a gas outlet hole 12 is enlarged due to movement of a cylinder in interruption direction. When a piston 5 integrally formed for the cylinder 7 moves in interruption direction, even if the blowout area is initially small, pressure of a buffer chamber 15 is increased; therefore, an gas quantity blown out from a nozzle 8 is large, a blowout area of the gas outlet hole 12 is small; therefore lowering of the pressure of the buffer chamber 15 is restrained. At the end, the pressure of the buffer chamber 15 is lowered; however, since the blowout area of the gas outlet hole 12 is large, the blowout gas quantity is large, and time of holding interruptible gas quantity is increased.

Filed: 1993-02-16
Abstract: PURPOSE:To enable the title p-type carrier concentration to be controlled in excellent controllability and reproducibility by a method wherein the intensity of laser beams irradiating the surface of a substrate during the growing step of cadmium telluride is to be controlled. CONSTITUTION:The surface of a substrate 7 during the growing step of cadmium telluride is irradiated with laser beams whose output is to be controlled so that the p-type carrier concentration in arsenic doping step may be controlled. For example, within an MBE chamber 1 maintained in ultrahigh degree of vacuum, Cd and Te2, Cd and As4 are fed to the whole surface of the substrate 7 respectively from a cadmium telluride cell 3, a cadmium cell 4 and an arsenic cell 5. Besides, the surface of the substrate 7 comprising the cadmium telluride is irradiated with the laser beams emitted from a laser source 6. Furthermore, the intensity of laser beams is increased to heighten the carrier concentration while increasing the telluride hole concentration to meet the surplus cadmium requirement. On the contrary, in order to lower the carrier concentration, both the laser beam intensity and the telluride hole concentration are to be decreased.

Title: Speed controller of induction motor
Inventor: YAMAGUCHI HIROSHI
IPC: H02P27/02
Filed: 1984-02-15
Abstract: PURPOSE:To stably control the speed of an induction motor by reducing the variation of a firing angle smaller than the normal value or not altering it when the voltage applied to the motor is once raised and again decreased. CONSTITUTION:A microcomputer 5 counts a speed signal B, compares it with a speed command signal C, delays the phase at the phase decided by the timing of the zero point detection signal A of a commercial power source, and outputs a signal D. The signal D is transmitted to a solid state relay 10, thereby controling an induction motor 11. When the magnitude of a power source voltage signal E is monitored and the power source voltage is raised and immediately decreased, the firing angle is not varied. Thus, even if the power source voltage is varied, the delay of the speed of the motor can be prevented, thereby stably controlling the speed.

IPC: F16J15/10
Filed: 1995-02-15
Abstract: PURPOSE: To provide a shield material capable of being deformed without being flowed, and capable of sealing a space, and further to provide the technique for shielding. CONSTITUTION: A shield material 1 comprising the crosslinked copolymer of polyvinyl alcohol with polyacrylamide is immersed in an acidic liquid 7 to contract its volume. The joint sites 5 to a box 3 are separated from each other to form a space, into which the contracted shield material 1 is inserted. Subsequently, an alkali liquid is injected into the shield material through the space to expand the shield material 1, and the joint sites 5 are subsequently brought into contact with each other to seal the space between the joint sites 5. The shield material 1 is excellent in sealability, because the change in the pH causes the expansion of the volume of the shield material 1 and the good correspondence of the shield material to the shape of the space. Since the shield material is solid, it can well be held in the space, and also since it does not flow, it can easily be handled.

Abstract: PURPOSE:To enable position information of a traveling body to be detected with an accuracy exceeding a detection resolution of a light-reception element by detecting a flux of light through the slit opening of both a slit member and a mask member at a plurality of light-reception parts and then utilizing the detection signal. CONSTITUTION:Two slit openings with slit openings in a direction which crosses the direction of traveling are provided at a slit member 3 which is connected to a traveling body and can move in a direction marked by an arrow 102 and a fixed mask member 4 so that only one of both slit openings matches. Therefore, the flux of light of a light-projection means 2 passes through the matched slit opening and the next matched slit opening when the member 3 slightly moved and then impinges on a light-reception surface 1a and then forms a slit image at a specified position and a different position. Light-reception parts 1b and 1c output a position signal corresponding to the incidence position. At this time, the amount of change of the slit image is larger than the amount of traveling of the member 3 and the position information of the member 3, namely the traveling body, can be detected highly accurately than the position resolution which is peculiar to a light-reception means 1.
