Title: Power supply switching device
Inventor: TAKAHASHI AKIRA
IPC: H02J1/00
Filed: 1993-02-05
Abstract: PURPOSE:To make it possible to switch a plurality of DC power supplies by connecting the positive side of a first DC voltage to a terminal to which a second DC voltage is applied through a particular diode and by taking out the output between the terminal and the cathode of the diode. CONSTITUTION:A first DC voltage V1 set to equipment side is connected to a pin 11 of a jack 10 to which a second DC voltage V2 is applied through a power switching diode 19 connected in forward direction, and the output is taken out between the pin 11 and the cathode of the diode 19. And when the relation of V2>V1-Vf (Vf is the voltage of diode 19 in forward direction) is satisfied, power is supplied to the second DC voltage V2 regulator without using a switch 18 in the jack 10. At this time, the switching function for DC power supplies V1 and V2 is provided by the diode 19. In consequence, the switching of DC power supplies V1 and V2 can be performed within the jack 10 without using a switch.

Title: Output system for application state of control table
Inventor: SUDA NORIKATSU
IPC: G06F11/28
Filed: 1989-01-27
Abstract: PURPOSE:To accurately and effectively check the programs by analyzing a source program and by outputting the calling relation between the reference update history of a control table and other programs in the form of a control table application state list so as to understand more easily the calling relation. CONSTITUTION:A syntax structure analyzing means 2 informs a history information production means 3 of the reference updata information on a control table 9 at its reference update and the call information at call of other programs respectively. The means 3 arranges these informed information as the control table application command information and the program call history information to store them in each store means. Then a history information editing output means 7 edits both information including the context between them into an easy-to-understand form and outputs it to a control table application state list 8. Thus it is possible to accurately and effectively check the programs having the close interfaces among them via the table 9.

Title: Nitridge semiconductor laser device
Inventor: YAMADA TAKAO
IPC: H01S5/00
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To improve an output of a nitride semiconductor laser device and stabilize the shape of laser light by providing an etching surface protruded from a resonance surface substantially perpendicularly to the resonance surface, and forming on the etching surface a thin film reflection mirror for reflecting laser light. SOLUTION: An n type layer 12, an active layer 13, and a p type layer 14 are stack in order on a saphire substrate 11 to construct a double hetero structure. In the present laser device, a reflection mirror 20 is formed on an etching surface corresponding to the direction of laser emission for reflecting the laser light. With the reflection mirror 20 formed as such the laser light is prevented from transmitting through the n type layer 12 and the saphire substrate 11 so that it is not correspondingly absorbed to improve an output thereof. The reflection mirror 20 when being formed with a mertal thin film is formed, separated whereby the metal thin film makes contact with an electrode to prevent short-circuiting from being produced between electrodes.

Title: Field effect type electrostatic induction thyristor
Inventor: TANAKA YOSHIMITSU
IPC: H01L29/749
Filed: 1989-01-26
Abstract: PURPOSE:To obtain a FET type electrostatic induction SCR by a method wherein an electrostatic induction SCR of PNPN structure is provided, where a fourth layer is provided inside a third layer, the third and the fourth layer are connected to a first electrode, and a gate electrode is provided on the surface of the third layer between a first and the fourth layer through the intermediary of an insulating film. CONSTITUTION:In a SCR of specified structure, a parasitic FET which makes an electrode G serve as a gate occurs and a P layer 3 under the electrode G serves as a channel. The concentration of the P layers 3, the space between them, and the concentration of an N layer 1 are so determined as to enable the P layers to be connected together with a depletion layer when the potential of the electrode G is zero, and electrodes A and K are not electrically connected together. When a voltage higher than the threshold of a parasitic mos is applied to the electrode G, the electrodes A and K are electrically connected with each other. Even if a SCR is kept in a cutoff state, the cathode K happens to be higher than the anode A in potential due to a resonance current, but as a diode, which allows a current to flow from the P layer 3 to the N layer 1 in the direction opposite to that of a current which flows from the P layer 2 to the N layer 1 through another diode, is formed, an opposite direction current which flows from the electrode G and the cathode K to the anode A is made to flows, so that a current carrying capacity becomes equal in both a forward and a reverse direction.

Title: Used/new toner cartridge judging device
Inventor: HIROSE KATSUMI
IPC: G03G21/00
Filed: 1990-01-31
Abstract: PURPOSE:To reduce the cost of a device by judging a used/new toner cartridge from the fact that the similar detection is carried out or not while printing is carried out within a prescribed number of sheets from the time paint when it is detected that toner is left a little. CONSTITUTION:The toner cartridge 24 is used for a long period, the toner is consumed, and the absence of the toner is detected by a magnetic sensor 27, for the first time. The counted values of a warning counter 55 and the used/new cartridge judging counter 56 are subtracted one by one whenever printing is carried out, till the absence of the toner is detected again. When the absence of the toner is detected, a CPU 51 reads out the value of the counter 56. When it is subtracted till 'zero', it means that a new cartridge is used for a long period. On the other hand, when the absence of the toner is detected before the counted value of the counter 56 is subtracted to 'zero', it corresponds to the fact that the cartridge 24 is not replaced. Thus, a fuse and a circuit for identification are eliminated, and the device is produced at low cost.

Title: Scanning control method of scanning type copying machine
Inventor: TAKAHASHI MASAHARU
IPC: G03B27/50
Filed: 1983-02-08
Abstract: PURPOSE:To complete scanning without using any parts such as a limit switch by monitoring the scanning time of a carriage and completing the scanning of the carriage preferentially when the scanning time exceeds a maximum permissible scanning time. CONSTITUTION:A main control part 22 is provided with a timer 23 to monitor, i.e. measure the scanning time from the beginning of the scanning of the carriage. A controller waits for a detection signal for the rear end of a copy form from a form sensor after the scanning is started, but when there is not this signal, the main control part 22 decides invariably on whether the timer 23 for the longest scanning time finishes measuring the time; when the length of the copying form is larger than the length corresponding to the maximum permissible scanning distance of the carriage, the main control part 22 completes the scanning before the signal for the rear end of the form is inputted to generate a scanning completion signal. Consequently, a light source activating signal is turned off and the timer 23 is also turned off.

IPC: B65G47/52
Filed: 1987-01-28
Abstract: PURPOSE:To feed a load body to the inside of a hopper without assistance, by installing a driving means which displaces a vessel receiving structural body freely up to a reversal position from an almost horizontal position. CONSTITUTION:When a container B containing a load body A is inserted into a container receiving structural body 15 from an inserting port in keeping a conveying position state intact and set in a regular position, a driving means 16 operates, displacing the container receiving structural body 15 up to a reversal position from the horizontal position. In this state that it is turned to the reversal position, a slide plate 21 is opened upward as far as a proper distance by an opening means 40, whereby the load body A flows into the inside of a hopper 6 in succession with its own weight from a lower part of the container B. After the load body A is fed to the inside of the hopper 6, the driving means 16 operates again and thereby the container receiving structural body 15 is restored to the horizontal position, and furthermore, in succession to this, a discharge door is driven for its opening or closing, thus the container B is made to escape to the lower part with its own weight.
