Title: Semiconductor laser device
Inventor: SUGINO TAKASHI
IPC: H01S5/00
Filed: 1984-05-08
Abstract: PURPOSE:To produce a semiconductor laser device, in which stable single longitudinal mode oscillation is obtained and a reflecting section between cavities is shaped in the cavities, by partially forming a recessed section onto a substrate and positioning one part of a striped electrode just above or just under a section adjacent to the recessed section. CONSTITUTION:A recessed section 11 is formed to a substrate 10. An SiO2 film 16, a p side ohmic electrode 17 and an n side ohmic electrode 18 are shaped. A striped window for the electrode formed to the SiO2 film 16 is arranged just above a section adjacent to the recessed section 11 in the substrate 10. When beams from a cavity l3 are propagated to a cavity l4, one part of beams distributed to an active layer 13 is reflected by a junction section between both sections l3, l4 because the shape of the active layer or a clad layer 12 changes in both sections. Reflection is also generated similarly in a junction section between l4, l5, oscillation modes are shaped in the cavities of l3, l4, l5, and beams having an oscillation wavelength mutually interfering in each oscillation wavelength are most amplified, and extracted to the outside as oscillation beams.

Title: Picture output level stabilizing device
Inventor: TSUKUI TOSHIO
IPC: G06K9/20
Filed: 1985-04-30
Abstract: PURPOSE:To stabilize the output level of the picture reading device of a film- shaped sheet by detecting a reading interval and changing the gain of an automatic gain control amplifier. CONSTITUTION:A detecting pulse from a reading line detecting part 8 is sent to a CCD driving circuit 6 and detected by a resetting circuit 11-1. By using the detecting pulse as a resetting signal, the interval of the detecting pulse is measured by a counter 11-2 in a reading line interval detecting part 11. The measured value is converted to an analog quantity by a D/A converting device 11-3 and the peak value of the analog quantity is held by a sample holding circuit 11-4. The held voltage value is compared with a standard value and the gain of an AGC amplifier 12 is controlled only for a part corresponding to the difference.

Title: Store number processing system
Inventor: KONDOU YOUJI
IPC: G06Q40/02
Filed: 1982-05-31
Abstract: PURPOSE:To ensure an addition of store numbers when the store numbers are totally controlled for each terminal within a terminal controller for stores and the transaction data is transferred to a host, by referring to a store number table showing a hierarchical structure of TC store number process store number original store number. CONSTITUTION:When the transaction data of the same store are fed consecutively, the account number of the data is first fed in full digits. This input data is transferred to a buffer 5 of a terminal controller TC, and a control processor 6 counts the number of digits. With a 10-digit input data, the upper three digits are taken out and stored in an original store number area 9c of a store number table 9. Then the store number in the account number can be omitted for input of the next and subsequent transaction data. When the next transaction data is fed, the processor 6 detects a digit number 7 and then takes out the store number which is previously stored in the area 9c of the table 9 to add to the number to the head of the data. Then a 10-digit data is restored.

Abstract: PURPOSE:To perform the inspection and cleaning of a corona discharge wire without removing a device by providing a corona discharge wire connected to a knob at one end and a spiral spring through an insulation wire at the other end, and pulling and rewinding the corona discharge wire crossing a cleaning pad. CONSTITUTION:As a knob 6 is pulled from a fixed stay 10, a corona discharge wire 1 and an insulation wire 3 are pulled, and a takeup reel 8 is driven to rotate. A spiral spring 9 is thus charged up. When this wire 1 is pulled, the wire 1 rubs a pad 5, and the contamination of the wire 1 is removed. The pulled wire 1 is inspected, and remaining contamination is removed with cloth or the like. As pulling force to the knob 6 is loosened, the reel 8 rotates to return by returning force of the spring 9, and the insulation wire 3 is taken. The wire 1 rubs the pad 5 to remove contamination at this time as well. The corona discharge wire 1 can thus be inspected, cleaned, or replaced without removing a corona discharge device.

Title: Laser oscillator power supply
Inventor: SASAKI NORIAKI
IPC: H01S3/10
Filed: 1990-04-11
Abstract: PURPOSE:To protect a switching element against damage by a method wherein it is judged that a drive signal is normal or not at the inverter end of a transmission line provided between an inverter circuit and a drive signal output circuit, and when it is found that the drive signal is abnormal, a laser is made to stop oscillating. CONSTITUTION:When a drive signal is not normally given to a MOS FET 9 through the intermediary of a gate amplifier 5 due to that an optical fiber comes off from a transmitter 2 or a receiver 4 or the transmitter 2 is not turned ON because of malfunction, or when an optical signal serving as a drive signal of the MOSFET 9 becomes abnormal, the receiver 4 outputs a high or a low direct voltage output. At this point, as an input capacitor 13 of a pulse discriminating circuit 10 shuts off a direct voltage, a FET 16 is turned OFF, the output of the pulse discriminating circuit 10 becomes low, and the output of an AND circuit 11 becomes also low. In this case, a laser oscillator control circuit 1 stops the operation of an oscillation circuit 1a receiving the output of the AND circuit 11 to stop the oscillation of a laser, whereby the MOSFET 9 of the inverter circuit 6 can be protected against damage.

Title: Racket with toss function
Inventor: IWAMURA RYUICHI
IPC: A63B49/08
Filed: 1994-03-28
Abstract: PURPOSE:To easily and quickly exercise a toss before a game by exposing a rotary roller which displays selectively either the surface or back plane over a grip head and supporting the roller in the inside of a grip rotatably and so as to be stopped at a prescribed position. CONSTITUTION:In a game such as tennis, etc., it is decided whether a player selects a service game first or a court by the toss before the game is started. The toss is exercised by a method to rotate a racket as a top setting a head downward and to hit the surface or the back plane of the racket. However, this method takes much time by shoving a result to an opponent by picking up the racket so as not to change the surface and the back plane, and also, the racket is easy to be impaired. To solve such problem, the rotary roller 1 which displays selectively either the surface or back plane is exposed over the grip head 2, and also, the roller 1 is supported rotatably and so as to be stopped at the prescribed position in the inside the grip.

Abstract: PURPOSE:To minatualize a scanning mirror system for illumination by fixing a light source and a first parabolic mirror to a device main body, moving a second mirror in parallel with an original and successively illuminating the surface of an original in the shape of slits. CONSTITUTION:A halogen lamp, the first parabolic mirror 2, the original platen glass 4, the original 5 and a lens 9 are relatively fixed to the device main body of a copying machine 12.

The cross-section shapes of th mirrors 3a and 3b are not perfectly parabolic but that in their shorter direction are cylindrical shape decided by a fixed parabolic line and they are arranged to have focul points in the vicinity of the surface of the original. Moreover, since the mirrors 3a and 3b are moved in parallel in the direction of an arrow C, they sufficiently and stably receive the parallel luminous fluxes 20 from the parabolic mirror 2 and illuminate the original 5 in the shape of slits. Thus, the illumination system can be miniatualized.

Title: Twist detecting device in pipe conveyer
Inventor: KURODA KIMIHIDE
IPC: B65G15/64
Filed: 1990-04-09
Abstract: PURPOSE:To prevent belt damage, ease maintenance and inspection, and improve detecting function by forcedly expanding part of a rounded outward carrying belt to form an opening, and abutting a detection element to an opening side edge to be inserted in an opening for detecting the around-axis rotation of a conveyer. CONSTITUTION:For example, the twisting of an outgoing belt 1A in a counterclockwise direction causes an outward side edge part 1c a detecting roller 14 leftward. This rotates a detecting ring 12 too in a counterclockwise direction to correct the twisting. Concurrently a driving plate 15 moves together with the movement of the detecting ring 12 to actuate micro switches 16 and 16 for informing the twisting. This constitution prevents belt damage, lessens the number of items of parts, and eases maintenance and inspection.
