Title: Manufacture of heat-insulating box
Inventor: WAKUMIZU TERUYOSHI
IPC: B29C39/26
Filed: 1981-04-09
Abstract: PURPOSE:To shorten the time of expansion for an expansible heat insulator by using a  system in which an air vent hole having a gradually enlarged diameter is provided  from the upstream side of the expansible heat insulator toward its top as a final expansion place on the back wall turned upwards of an outer box when the heat insulator is expanded inside the heat-insulating box of a refrigerator, etc. CONSTITUTION:The back wall 3a of an outer box 3 is turned upwards and the outer  box 3 is connected with an inner box 2. Then, a raw liquid is injected into between  both the boxes 2 and 3, and the injection hole 21 is closed with a sealing member 23.  As the raw liquid expands, air and gases are pushed out, as shown by arrows representing the magnitude of speed gradient, from air vent holes 20A, 20B, and 20C, and an  expandible heat insulator 4 partly leaks from the smallest air vent hole 20A, solidifies,  and closes the hole 20A and then closes the holes 20B and 20C in sequence. After the solidification of each hole, inner and outer jigs are removed, the expansible heat insulator leaked and solidified from the holes 20A, 20B, and 20C is removed, and the  holes are covered with a sealing member 22. By this, a heat-insulating box is completed. Thus, if the removal of air and gases is completely performed, the formation of honeycombs by the stagnation of air in the expanded heat insulator 4 can be avoided.

Title: Photodetector device
Inventor: KURAHASHI AKIRA
IPC: H01L31/10
Filed: 1989-03-07
Abstract: PURPOSE:To make it possible to change light detecting characteristics by forming this photodetector device with a sensor complex and a differential amplifier. CONSTITUTION:This photodetector device is composed of the following parts: a sensor complex having first photodetectors PD1 and second photodetectors PD2 having the different light detecting characteristics from those of the first photodetector PD1; and a differential amplifier whose negative input terminal is connected to the first photodetector PD1 and other input terminal is connected to the second photodetector PD2, and to which a power source voltage having a single polarity is imparted. When the same light is projected on the first and second photodetectors PD1 and PD2, the different output are generated in the respective photodetectors. The difference between the outputs is amplified in the differential amplifier 2. The amplified difference in outputs has a single polarity and becomes a value which is proportional to the optical component in the specified wavelength band in the detected light. Since the differential amplifier 2 is constituted so that the input signal can be varied and amplified, the wavelength band of the optical component to be detected becomes variable. Therefore, an optical filter and a spectroscope are not required.

Filed: 1982-03-31
Abstract: PURPOSE:To reduce the optical waveguide loss by the gap between optical waveguides and a clad, by generating the light quantity areas where the quantities of the light incident from both sides are added to each other and are doubled in a pair of exposed parts of a photosensitive resin layer having masks on both sides. CONSTITUTION:If a pair of exposure parts 6 are formed to as to face each other on masks 5 applied on both sides of a photosensitive resin layer 4, and incident light 9 is irradiated from the parts 6 of the two sides, the respective quantities of light are added to each other and doubled light quantity areas 7 are formed. The photosensitive resin in the areas 7 receives high energy and increases the degree of polymn., hardness and transparency. The optical waveguides 2 formed consequently have a difference in refractive index from the other areas 8 and photoconductivity is imparted thereto. The clad 1 having the optical waveguides 2 formed in accordance with the difference in the degree of polymn. is constituted alone and produces no gaps between the same and the waveguides 2; therefore, the light loss is reduced, the waveguide plate is strong against deformation such as bending and does not cause stripping.

IPC: H04N9/85
Filed: 1982-04-02
Abstract: PURPOSE:To prevent jitter from appearing on the output screen of a computer by reducing a phase shift of a signal supplied from the computer to a monitor from a synchronizing signal supplied from a player to the monitor by a specific extent. CONSTITUTION:A signal R-B from the microcomputer 1 is supplied to a switcher 4 through a delay circuit 6 and a control signal SD for the delay time of the circuit 6 is supplied from a player 2 to control the delay time to 0 or 140nsec. Therefore, the delay time of the circuit is 140nsec in a frame period wherein a synchronizing pulse Ps is shifted in phase by 140nsec to hold the phase continuity of a chrominance signal during the variable speed reproduction of the player 2 and 0 in other frame periods, so the signal R-B supplied from the computer 1 to the monitor 5 do not shift in phase by 140nsec from the synchronizing pulse Ps supplied from the player 2 to the monitor 5. Consequently, no jitter appears on the output screen 1 of the computer during the variable speed reproduction of the player 2.

Title: Video tape copy preventing signal insertion releasing device
Inventor: WADA TAKAYOSHI
IPC: G11B20/02
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To obtain a video tape copy prevention signal insertion release device by which a user can simply insert/release a copy guard. SOLUTION: A video signal enters a synchronizing separator circuit and a video switch circuit after passing through a buffer. The synchronizing separator circuit generates a vertical synchronizing signal and a horizontal synchronizing signal for the video signal. A control signal for the video switch is produced by counting and processing the obtained two kinds of the synchronizing signals. Furthermore, oscillators 1, 2 generate a guard signal to be inserted to the video signal. The video switch selects the video signal directly received and the guard signal on the basis of the control signal of the video switch and provides an output of the selected signal. The outputted signal is amplified by an amplifier circuit and outputted as the video signal to which the guard signal is inserted. In the case of releasing the insertion of the guard signal, the guard signal from the oscillators 1, 2 is replaced with a usual signal such as a composite signal or a DC.

Title: Two cycle engine
Inventor: TANAHASHI TOSHIO
IPC: F02B11/00
Filed: 1978-05-10
Abstract: PURPOSE: To effect continuous operation of self-ignited combustion by maintaining active thermal circumstance, necessary for self-ignition, in stable condition until end of compression stroke of an engine.  
     CONSTITUTION: Mixture compressed in a crank-chamber 8 is supplied into a cylinder-chamber 7 from a loop scavenging port 15 through a mixture control valve 24 and a scavenging air passage 17 when a piston 6 opens the loop scavenging port 15. Air is not supplied through a cross-scavenging port 16 under lower load operation because an air control valve 36 is closed, and flow of mixture is contracted during passing through the control valve 24 because the mixture control valve 24 contracts the scavenging air passage 17. Consequently, flowing speed of the mixture is reduced and disturbance caused upon passing through the contral valve 24 is eliminated until the mixture reaches the loop scavenging port 15, thus the mixture flows slowly into the cylinder-chamber 7 as laminar flow, and thereby, dissipation of heat through the wall of the cylinder may be restricted.
