Title: Video transmitter and video transmission system
Inventor: NAMIGATA TAKESHI
IPC: H04N21/6373
Filed: 1995-06-29
Abstract: PURPOSE: To transmit plural camera videos with small line capacity. CONSTITUTION: A computer 20 makes a camera video input device 12 select an arbitrary one of video cameras 10-1 to 10-N by issuing a command. The computer 20 sends out a selected camera video from an interface 32 to a network. When the cameras 10-1 to 10-N are switched in circulation at a fixed time (for example, ten seconds) interval and video transmission is started up corresponding such switching, all camera videos are transmitted as still pictures being updated at every ten seconds. When the video transmission is started up at a period shorter than the switching of the camera video, each camera video is transmitted at a shorter update rate until switching to the next camera video is performed.  When the video transmission is started up corresponding to the switching of the camera video and also, the video transmission of a specific camera video is started up at the shorter period, only the specific camera video is transmitted at the shorter update rate.

Title: Compound semiconductor device
Inventor: HISAMATSU TADASHI
IPC: H01L33/16
Filed: 1987-06-30
Abstract: PURPOSE:To prevent generation of migration, etc., of electrode metal by filling cracks generated within a semiconductor layer with a semiconductor material of amorphous or miniaturized grain size polycrystal structure in a compound semiconductor device depositing a compound semiconductor layer on a substrate. CONSTITUTION:A GaAs layer 3 is deposited in the thickness of 3.5mum or more on a Si substrate 1 through a buffer layer 2. After GaAs layer is deposited at 700 deg.C and an interprocess device is then cooled up to a temperature near the room temperature, cracks 4 are generated on the GaAs layer 3 due to the difference of thermal expansion coefficients of Si and GaAs. Next, temperature is then raised again upto about 400 deg.C within the furnace and thereby GaAlAs 5 is deposited in the thickness of about 0.05mum. This low temperature deposited layer 5 has amorphous or miniature grain size polycrystal structure. Thereafter, if temperature is lowered again to the room temperature, further cracks are no longer recognized because the low temperature deposition layer 5 filling the recessed portions of cracks 4 alleviates stress resulting from difference of thermal expansion coefficients of GaAs and Si. A solar battery element or light emitting diode can be formed by forming a metal layer 6 to the surface of such semiconductor substrate.

Title: System controller
Inventor: ITOI TAMOTSU
IPC: H04Q9/00
Filed: 1990-06-22
Abstract: PURPOSE:To prevent a loop from being formed by changing over a switch to interrupt an earth line when an analog signal line to send an analog signal therethrough is connected between 1st and 2nd equipments. CONSTITUTION:Positive and negative analog signal lines 16a, 16b are formed to allow an analog signal to be sent, and when a negative control signal line 23b is interrupted, the line 16b acts like the line 23b. Thus, a control signal generated from a control circuit 19 is sent to a decoder 21 and a sound source device 1 is controlled in response to the control information included in a control signal. In this case, since the line 23b is interrupted, a problem that forming of a loop is formed through an earth line is not caused.

Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To enable an operator to open a cover body of a personal computer by his single hand by providing a transmission means which transmits the displacing force of one of 1st and 2nd control levers to the other. SOLUTION: When a 1st control lever 5L is pressed toward an arrow C and at the same time displaced toward an arrow A, the engagement is canceled between a 1st hook 7L and a 1st engagement part 8L and also a control bar 9A is displaced toward the arrow A by the pressing force applied onto an engagement surface 5B. Thus, a 1st coupling member 9 is pulled toward the arrow A and a rocking member 14 is turned counterclockwise. As a result, a 2nd coupling member 11 moves in a guide tube 12 and a pressing part 13C positioned at the coupling part to a control bar 13A set at an end part is displaced toward the arrow A. Then a 2nd control lever 5R is displaced toward the arrow A and set at its non-lock position. Under such conditions, a lock canceling operation can be carried out by the lever 5L at the closing position of a cover body 3. So is with operation of the lever 5R.

Filed: 1990-06-23
Abstract: PURPOSE:To judge occurrence of memory effect by discharging a battery for a predetermined time, measuring the battery voltage and storing thus measured battery voltage, and measuring the charging time from the start to the end of charging operation. CONSTITUTION:A battery is discharged and the discharge voltage is measured. Charging time is then measured and the residual capacity of the battery is judged based on thus measured charging time. A judgment is made that the residual capacity of the battery is approximately zero if thus measured charging time is longer than a predetermined time. On the contrary, a judgment is made that a memory effect is produced in the battery if the charging time is shorter than the predetermined time and the measured discharge voltage is lower than a predetermined level.

Abstract: PURPOSE:To take numbers of copies in single reading operation and to perform picture processing freely by heating selectively an insulator layer formed on a photoconductive photoreceptor and forming an insulator image, and developing an electrostatic image which is formed on the basis on the insulator image by using toner particles. CONSTITUTION:A coater 4 forms the insulator layer 12 over the surface of the photoreceptor belt 1 and a thermal head 9 is driven over it to form the positive insulator image on the photoreceptor belt 1. This insulator image is charged electrostatically by a charger 13 and passed right under an exposure device 14 by the movement of the belt 1 and at this time, the electrostatic latent image conforming with the insulator image is formed. A toner image is formed by the electrostatic latent image to form a recording picture on a form 18. Thus, numbers of the same recording pictures of excellent quality are formed and the picture is formed electrically by the thermal head 9, so various picture processing is possible.

Title: Method for composite reverse weave tying of 'oshima-tsumugi' and textile fabric of 'oshima-tsumugi' formed by composite reverse weave tying
Inventor: HIRATA TAKAZO
IPC: D06P5/00
Filed: 1988-07-02
Abstract: PURPOSE:To enable composite reverse tying capable of forming the same patterns in both the vertical, left and right directions by forming plural weft yarns in a loop form and combining roll-tying with warp yarns and then steam-tying. CONSTITUTION:Plural weft yarns 1 are formed into loop forms 3, 3', 4 and 4'. Roll- tying with warp yarns 2 is combined with steam-tying, e.g. patterns (A) are formed by roll-tying of the loop 3' and patterns (B) are then formed by roll-tying of the loop 3. The patterns (A) and (B) are formed by rotation 180 deg. with a point (C) as the center. Thereby, a suitable number of patterns (A) are formed by the loop 3' to form a body part 6 and a suitable number of scattered patterns 3 are formed by steam-tying to form a body part 6'. Thereby, a suitable number of the patterns (A) are arranged parallel in the same state and a suitable number of the patterns (B) are then continuously formed in a state of rotation 180 deg. relatively to the patterns (A). As a result, 'KASURI' (splashed patterns) weave tying can be carried out without reversing the patterns back and forth, left and right when made into 'KIMONO' (Japanese traditional costume).

Abstract: PURPOSE:To enable the execution of thermal transfer recording of ordinary paper or thermal recording of heat-sensitive paper by making a control to move a head to a recording position corresponding to an ordinary paper recording mode or a heat- sensitive paper recording mode by an operation of setting either of these modes.

When heat sensitive paper is used as the recording paper, on the other hand, the paper is discriminated to be the heat-sensitive one by the mark discriminating element 18a, and actuators 36-1 and 36-2 are made to operate to move the thermal head 10. In more detail, the feeding direction of the recording paper is shifted by drawing in a shaft 40 by the actuator 36-1 simultaneously when a shaft 42 is moved onto the heat-sensitive paper 24 side by the actuator 36-1, and thereby the thermal head 10 located at an initial position 10' is moved to a heat-sensitive paper recording position located on the feeding side of the paper off a thermal transfer film 12.
