Title: Apparatus and method for injection of noise
Inventor: HANEDA SHOJI
IPC: G01R31/00
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a noise injection apparatus or the like which is small and lightweight, and by which a noise can be injected safely into a power-supply line while a high voltage is not generated by itself. SOLUTION: A noise generation source NS generates a noise. The noise is supplied, via a switch SW1, a variable resistor VR1, and capacitors C1, C2, to a pair of power-supply ends provided at an apparatus to be tested as an object for a noise test. The noise is cut off substantially by respective poles of a single-phase AC commercial power supply and by choke coils L1, L2 which are connected across the power-supply ends at the apparatus to be tested, and it is not supplied to the side of the commercial power supply. On the other hand, a voltage which is supplied by the commercial power supply is supplied, via the choke coils L1, L2, to the power-supply ends at the apparatus to be tested.  As a result, according to the principle of superposition, the sum of a voltage of the noise supplied by the noise generation source NS and the voltage supplied by the commercial power supply is applied to the power-supply ends at the apparatus to be tested.

Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of decreasing the number of wirings from a main board loaded with a game control means. SOLUTION: When a detection signal from a full tank switch 402 for detecting that a designated amount of game balls are present in a lower tray on the surface of a game machine indicates the full tank state, a CPU of a main circuit board outputs a prize ball control command indicating a shoot stop command of a hit ball to a prize ball control circuit board. The prize ball control CPU of the prize ball control command outputs a shoot stop command to the shoot control circuit board according to the prize ball control command. The shoot stop command is included in the prize ball control command and output from the main circuit board, whereby wiring extending from the main circuit board to the shoot control circuit board is not needed. Accordingly, drawing around of wiring in the game machine can be simplified.

Title: Electrostatic recording sheet
Inventor: YAMAUCHI KEIJI
IPC: G03G5/02
Filed: 1988-12-27
Abstract: PURPOSE:To prevent gathering dropout of a dielectric layer even at the time of recording at low temperatures and to form a sharp record high in contrast by specifying the surface tension of the surface of the dielectric layer. CONSTITUTION:The electrostatic recording sheet is obtained by successively laminating on a support a conductive layer and the dielectric layer, the surface tension of which is controlled to 33 - 45dyne/cm measured by the method according to JIS K 6768. If the surface tension is below the range, the layer gathering dropout occurs at a temperature of <=10 deg.C, and if over the range, the record density lowers, and fog occurs. The surface tension can be regulated in the range by using for the resin of the dielectric layer a copolymer containing both a monomer of formula I and a monomer of formula II in both of which R1 is H or methyl; R2 is 4 - 18 C alkyl; and R3 is phenyl or Cl, and the copolymer may contain a pigment, such as calcium carbonate.

Title: Optical absolute encoder
Inventor: MATSUZOE YUJI
IPC: G01D5/36
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To make acquirable a sufficiently large photocurrent signal from a light receiving element for detecting the rotational angle without causing any increase in load resistance by juxtaposing the light receiving element for detecting the rotational angle and a light receiving element for correcting the quantity of light sequentially along the rotational direction of a rotator in the illumination region of a light beam transmitted through the transmitting part of a rotary slit plate. SOLUTION: A light beam radiated from an LED 15 passes through the transmitting part of the M series track 12 on a rotary slit plate 22 and arrives at a light receiving element for the M series and a light receiving element for correcting the quantity of light. More specifically, the M series track 12 also serves as a track for correcting the quantity of light. Since the rotational angle is detected and the quantity of light of a light emitting means is corrected using the light transmitted through the rotational angle detection track 12 on the rotary slit plate 22, a light receiving element for correcting the quantity of light is not required to be arranged independently from the light receiving element for detecting the rotational angle.  Consequently, the light receiving area of the light receiving element for detecting the rotational angle being arranged in the illumination region can be increased by a factor of about 2.
