Title: Protection material for stacking plate material
Inventor: TAKAHASHI TOKUO
IPC: H01L21/50
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To eliminate generation of paper dusts, adhesion of dusts due to static electricity and failure such as stop of mechanical operation due to defective removal, without giving damage and contamination on the surface and damage to lead such as deformation, by forming a protection material of the same kind material as the plate material. SOLUTION: A protection material 100a is inserted between the lead frames 200a, 200b when the lead frames 200a, 200b are laminated as the stacked material. The protection material 100a is formed of the materials of the same kind as the lead frames 200a, 200b. For example, a thin plate of metal material having excellent conductivity and higher strength is used. The surface contact is introduced between the protection material 100a and lead frames 200a, 200b. In this case, damage is not generated in the similar material and dusts do not adhere due to the electrostatic electricity because the protection material 100a is conductive. Thereby, the surface is free from damage, contamination and lead is also free from damage such as deformation. Moreover, paper dust is not generated and failure such as stop of mechanical operation due to the defective removal is not generated.

Filed: 1983-11-10
Abstract: PURPOSE:To enable the planar light emitting diode having a curved photo- releasing plane to be manufactured easily with good yield and good productivity by a method wherein a semiconductor layer forming a P-N junction is grown on the substrate surface having a groove previously formed, and thereafter the semiconductor layer is left by removing only the substrate, thus obtaining a required light-releasing plane. CONSTITUTION:Using the GaAs substrate, the groove 12 is formed on the side of the plane 11 of the substrate 10 where the P-N junction forming layer is grown. On the side of the plane 11 having this groove, the first semiconductor layer 14 of one conductivity type and the second semiconductor layer 15 of the other conductivity type are laminated as a double-layer by the use of the liquid phase growing method. Next, the second semiconductor or the second and first semiconductor layers are partly removed into a planar structure. Then, ohmic electrode layers 17 and 18 are formed on exposed surfaces 14c and 15c of the first and second semiconductor layers, respectively. Finally, the planar light emitting diode of dome form or cylindrical structure is obtained by selective etching removal of the substrate 1 with the layers 14 and 15 being formed.

Title: Illuminance sensor
Inventor: KITAMURA TSUNEHIRO
IPC: H03K17/94
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To provide an illuminance sensor that does not respond to changes in an external light due to an illumination light, but will immediately respond to the change in a natural light. SOLUTION: This illuminance sensor uses a solar battery SB to detect the lightness of external light and makes a variable impedance element VI conductive, when the external light is a prescribed value or over. A liquid crystal panel LC, whose transmittivity is adjusted by an external signal, is placed to an incident path of the external light to the solar battery SB. The transmittivity of the liquid crystal panel is controlled smaller, when the variable impedance element VI is conductive such that when the variable impedance element VI is not conductive. Furthermore, the transmittivity of the liquid crystal panel LC differs between the visible light region and infrared ray region. Thus, a hysteresis characteristic with respect to the illumination light and that with respect to natural light are made different.  Then the illuminance sensor has the hysteresis characteristic, that does not respond to the illumination light or light of head light at night, even when the light is received as the external light but that immediately responds to a sun light at daybreak.

IPC: G07F11/58
Filed: 1988-08-26
Abstract: PURPOSE:To shorten a necessary time for selling without damaging a commodity by reducing the speed of a commodity loading stand when the loading stand of a commodity vending machine receives the commodity at the receiving shelf of the designated commodity and approaches a commodity discharging port. CONSTITUTION:When a charge is inputted to the vending machine and a desired commodity S is designated, a purchase commanding signal is outputted from a control device 22. When the signal is received, a second electric motor 4 is activated and a commodity loading stand 2 is moved at a high speed to the position of a receiving shelf 1 for the desired commodity by a clutch 18. Next, the commodity S is fed out to the loading stand 2 by a first electric motor 1A. When the commodity S is received, the loading stand 2 moves at the high speed and approaches a commodity discharging port 3. When an abutting piece 19 of the loading stand gets in contact with a limit switch 20 in a highest part, the speed is switched to be low by a clutch 13 and the commodity is moved to the discharging port 3. Thus, the necessary time for selling is shortened.

Filed: 1988-08-26
Abstract: PURPOSE:To achieve a higher reliability and a reduction in detection time by generating directive beams of the same direction continuously when an object is detected to perform a continuous detection. CONSTITUTION:Ultrasonic vibrators S1-S5 are arranged on the same plane at an equal interval (d) and a directive beam B always makes a scanning sequen tially by a specified angle each as shown by Figs (a)-(e) varying delay time of delay circuits D2-D5 sequentially. Now, when an object (P) appears, an object detection circuit 2 outputs a detection signal if the beam B is in the state of Fig. (d) and a delay time control circuit 5 sends a control signal to the circuits D2-D5 by the signal so that in the subsequent scanning a detecting operation is performed only by a specified frequency with the beam B being maintained in the direction of the Fig. (d) as indicated by Fig. (e). The circuit 2 outputs a detection signal again and a signal processing section 3 generates a detection signal continuously. Hence, an object is determined to be detected thereby ena bling the transmission of an object detection signal to a display device 4.

Title: Vertically enlarged character printing system of serial printer
Inventor: MURAKAMI ISAO
IPC: B41J2/485
Filed: 1986-09-10
Abstract: PURPOSE:To prevent a space from being generated in a line feed portion of a vertically enlarged character, by a construction wherein a line feed pitch is made slightly smaller than the height of one line printing so that the printing of upper and lower lines can overlap on each other. CONSTITUTION:When a character A is vertically doubled to be printed, a master control part 1 retrieves a character generator 4 from the code of the character A to read the font of the character A and develop it in a RAM 3. In this case, each font is vertically developed two times to be doubled in the height direction. After that, the master control part 1 supplies a line feed command to a line feed control part 6 to feed a line by a height l of one line printing and reads the upper portion of the font from the RAM 3 to supply it to a printing control part 5; thus, the upper portion of the character is printed. Thereafter, the master control part 1 supplies a line feed command to the line feed control part 6. In this case, a line feed pitch is made smaller than the height l of one line printing so that the lower portion of the font is printed in the same column as a predetermined column. In this manner, upper and lower characters partially overlap on each other, which prevents the generation of a gap.
