Title: Distribution feedback type semiconductor laser element
Inventor: MASUBUCHI NOBORU
IPC: H01S5/12
Filed: 1984-12-22
Abstract: PURPOSE:To make it possible to perform arbitrary selection and operation at any of a plurality of different oscillating wavelengths, by constituting an optical resonator by a diffraction grating comprising a refractive index chaning part, which is formed by an electric field in a grating shape in a crystal body having an electrooptical effect, and arbitrarily selecting the grating constant of the diffraction grating in correspondence with the way of applying the electric field. CONSTITUTION:A laser diode is constituted by an N-type semiconductor layer 1, an active layer 2 and a P-type semiconductor layer 3. When a voltage is applied to electrodes 4 and 5, simulated emission light is generated from the active layer 2. A crystal layer 7 is made of, e.g., LiNbO3 and the like. Its optical axis A is oriented toward the horizontal direction together with the laminated semiconductor layer 1. On the surface of the layer 7, grating electrodes 8, which are formed by arranging a plurality of thin conductor layers in parallel at a specified pitch P, are formed. Leads are taking out of a plurality of the thin conductor layers constituting the grating electrodes 8 independently to the out side of the laser element. Voltages can be independently applied to the layers.

IPC: A61G7/05
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To improve a finger-pressure effect and air permeability by arranging independent projection parts of a specific thickness on a cushion material main body of a fixed total thickness so as to cut the periphery of its lower part obliquely inward. SOLUTION: The total thickness of the cushion material main body 11 is 40 mm to 100 mm. Many rectangular projection parts 12 are on the upper part of the main body 11.

Title: Magnetic card processor
Inventor: TANABE HARUO
IPC: G11B17/00
Filed: 1985-11-29
Abstract: PURPOSE:To find the illegal use of a card, to inhibit the vending operation and the rewriting of magnetic information, and to prevent the card from being used illegally by providing a drawing-out detecting mechanism which faces the magnetic information surface of an inserted card and operates in response to the drawing-out operation of the card. CONSTITUTION:When a magnetic card 5 whose balance remains is inserted into a loading part 11 while superposed upon a magnetic card 5 whose balance is zero and the upper card 5 is drawn out after a magnetic head 3 reads the balance of the upper card 5, the roller 41 of the card drawing-out detecting mechanism 4 reverses in response to the extraction and a light shield plate 43 turns off a photoelectric switch 47. A CPU, therefore, decides that the switch is on to inhibit the vending operation and returns the magnetic card 5, thereby preventing the card 5 whose balance is zero from being used illegally.

Title: Method and apparatus for maintenance of tape tension at inside of tape cartridge
Inventor: ERIKU SORIERU
IPC: G11B15/43
Filed: 1992-10-08
Abstract: PURPOSE: To keep the tension of a magnetic tape by unwinding the tape by a distance sufficient for recovering the allowable level of tape tension after the tape is transferred in the forward direction by a certain distance. CONSTITUTION: The selected tape property changing with the tape tension is monitored, and when it exceeds a predetermined amount, i.e., an amount showing that the tape tension is on a level lower than the satisfactory level, the tape is moved so that a different block begining part such as a block A comes in front of a write/read head, e.g. by performing the longer unwinding operation 17. Thus, the tape 5 is forwarded by the excessive distance corresponding to the space from the begining point of the block A to the ending point of a block D, i.e., the distance selected so as to recover the tape tension up to the desirable level.

Filed: 1987-10-26
Abstract: PURPOSE:To attain the error check with high reliability by adopting the constitution such that a readout beam is received directly by a readout detector with a pin hole so as to simplify the detection optical system, thereby detecting separately a write beam and a readout beam. CONSTITUTION:Only the write beam I transmits through a pin hole 32a and made incident in a detector 33 to be controlled, where photoelectric conversion is applied.

IPC: H03F3/34
Filed: 1986-11-12
Abstract: PURPOSE:To expand an operational margin against fluctuation in the characteristic of MOS transistors occurring in the manufacture by controlling the gate voltage of the MOS transistor for voltage-controlling of a sense amplifier such as P-ROM, corresponding to an electric current conducted through a ROM cell. CONSTITUTION:Since a MOSFET 6 is the same transistor as the ROM cell 30, if the channel width W and the channel width L f a MOSFET 1 and that 2, the same current is conducted through MOSFETs 2, 4, too. Therefore, if the current through the cell 30 is increased because of fluctuation in the power supply voltage or fluctuation in manufacture, a current through FETs 6, 2 also is increased. Accordingly, by making the W/L of a MOSFET 5 larger than the W/L of the FET 4, the resistance in apperance is increased to effect as a voltage control, hence the amplitude of the charge/discharge of digit lines can be regulated to be small, as a result, the operational margin can be expanded.
