Title: Optical box and projection television receiver
Inventor: KARASAWA JUN
IPC: G02F1/13
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent the soiling of the optical system, to simplify the disassembling and the assembling of the optical box which stores the system and to ease the cleaning of the system. SOLUTION: The light beams, which are emitted from a light source and include ultraviolet rays, are reflected by a mirror 12, the path is changed and are made incident on a liquid crystal element 13. The reflection surface of the mirror 12 is coated with an oxidized titanium film. Thus, even though organic dust is stuck to the reflection surface of the mirror 12, the dust is resolved by the ultraviolet rays made incident on the film and the mirror 12 is made hard to be soiled. The light beams, which are made into picture light beams by the element 13, pass a projection lens 14 and projected on a screen 2. At that time, the film coated on the surface of the lens 14 resolves organic dust. Thus, the construction of the box, which stores the optical system, is required to be less air tight and the disassembling and the assembling of the box are made easier.

Title: Automatic clutch control device
Inventor: IDOGUCHI MASARU
IPC: F16D25/12
Filed: 1984-10-26
Abstract: PURPOSE:To prevent an excessive load from being applied to a reduction gear so as to augment the safety by detecting change in rotational torque output from the reduction gear as an electric signal so as to disconnect a clutch auto matically when rotational torque exceeds the preset value. CONSTITUTION:When excessive engine torque is developed as compared with that for a normal operation while a car is running, an excessive strain is incured on an output shaft 4. This allows a magnetostrictive element 13 sticked on the surface of the output shaft 4 to be deformed accompanied with shaft (4) deformation permitting magnetic flux produced by the element 13 to be changed. Accordingly, electric current generated in an electromagnetic coil 14 which is located closely to the element 13, is changed in response to the change in magnetic flux of the element 13. Then an output information from the electro magnetic coil 14 is inputted into a program control circuit 15 through an input/ output interface 11. This permits an actuator 5 to be operated to disconnect a clutch 2 by way of an electromagnetic valve 7 when the excessive strain is detected.

IPC: H04B3/20
Filed: 1984-10-30
Abstract: PURPOSE:To suppress oscillation, i.e. singing of a loudspeaker system by automatically detecting howling caused in the loudspeaker device and controlling the loudspeaker gain. CONSTITUTION:Among a pair of signals (a) and (b) branched from the signal transmission line by the branching means 1, the signal (b) is delayed 5 to make a certain time difference between both signals. Furthermore, the signal (a) is branched 2 and between a pair of signals branched by phase shifting means 3, 4 and a phase difference of 90 deg. or about 90 deg. is given and then each is multiplied by the other signal branched 1 by the multipliers 6 and 7. The output signals of the multipliers 10 and 11 are integrated at a specified attenuation factor by the integrators 8 and 9. And with the arithmetic units 10 and 11, the absolute value or squared value of the output signal of the integrator is outputted. Then, with the adder 12, the outputs of the arithmetic units are added. By controlling the gain of the gain control circuit Q inserted in the signal transmission line by means of the output signal of the adder 12, the singing generated in the electroacoustic system including the signal transmission line L is suppressed.

Filed: 1992-08-26
Abstract: PURPOSE:To reduce coolant gas volume leaking from a clearance in a cylinder bore by loosely-fitting a tetrafluoroethylene resin piston ring into a groove which is provided at the outer periphery of a piston freely. CONSTITUTION:A piston 20 which is made of aluminum material and reciprocates inside a cylinder bore 17a with the rotation of a crank shaft 8 through a connecting rod 9 is provided with a groove 20a equipped with two pairs of piston rings 21 made of material whose main element is tetrafluoroethylene resin on its outer periphery. The piston ring 21 is guided to the groove 20a in a clearance between the piston 20 and the cylinder bore 17a so that the piston 20 may not be brought into contact with the cylinder bore 17a during moving. Moreover, a diametrical clearance between the piston and the cylinder bore is set at 1/100-1/300 time as wide as the diameter of the piston. Therefore, it is possible to obtain stable cooling performance even when leaking loss increases due to pressure ratio increase at the time of replacing coolant CFC12, which is generally used, with HFC134a.

Abstract: PURPOSE:To narrow the pitch of a track and to reproduce the recorded signal between tracks except the influence of crosstalk by dividing reflected light beams from a disk into approximately two, dislocating the phases of the peripheral parts of both divided reflected light beams, and obtaining a reproduced signal from a synthesized light beam. CONSTITUTION:A light beam 1 emitted from a semiconductor laser 1 of a light source is made into parallel beams by a collimator lens 2, reflected on a polarizing beam splitter 3, transmitted through a lambda/4 plate 4, and after that formed into a light spot on a disk 6 by a diaphragm lens 5. A reflected light beam J from the disk 6 is transmitted through the diaphragm lens 5, the lambda/4 plate 4, and the polarizing beam splitter 3, passed through a half mirror 8, and image-formed on a phase plate 9 by a convex lens 7, a reflected light beam K from the phase plate 9 is reflected on the half mirror 8 and image-formed on a light detector 11 by a detecting lens 10, and the reproduced signal is taken out. While the energy of the peripheral part of the reflected light beam K synthesized in this manner is weaken by optical interference, the energy of the center part of the reflected light beam K is emphasized to the contrary. Thus, the track pitch can be narrowed, and the signal recorded between the tracks can be also reproduced except the influence of the crosstalk.

IPC: H04W4/16
Filed: 1994-09-22
Abstract: PURPOSE: To prevent transmission of an unnecessary radio wave by confirming contents of the display device of a terminal station or confirming a dial tone at the time of originating. CONSTITUTION: A line control and radio equipment 2 of a host station continuously transmits the transmission signal of a channel 1 and sends an idle line signal 8 indicating whether two channels are idle or not. The terminal station receives and monitors them. The channel 2 is used only at the time of call incoming from a repeating exchange 1 or reception of call originating signals from terminal stations 3 to 5 in the host station. Each terminal station control part 13 always monitors the signal 8; and when there are two idle channels, it is discriminated that broadcasting speech is possible, and this state is displayed on a display device 14. Besides this display, the dial tone showing that broadcasting speech is possible is emitted from a receiver speaker at the time of hooking off the receiver of a telephone set 7.  If the signal 8 is not sent or there are not two idle channels, broadcasting speech is inhibited, and the dial tone showing that broadcasting speech is impossible is emitted at the time of hooking off the receiver of the telephone set 7.
