Abstract: PURPOSE:To smoothly pitch-feed a tape even if an electronic component is erected in a pocket of the tape by providing a tunnel for passing the component erected in the pocket of the tape due to a pickup mistake of a transfer head at a cover plate. CONSTITUTION:When a sprocket 4 is rotated, a cover tape 2a is peeled from a tape 2 by a peeling pawl 5 on the way, the tape 2 is then pitch-fed to a pickup position Q, where a transfer head 50 is vertically moved up or down to pick up an electronic component P by a nozzle 51, and the component is fed forward along the sprocket 4.

Abstract: PURPOSE: To perform swinging with fixed driving force at all times, to equalize the inclination speeds of forward inclination and backward inclination and to eliminate the unnatural feeling of an operation by using a pair of extendible/ contractible rods arranged symmetrically to a moving direction and connecting a swinging unit and a driving part. CONSTITUTION: When a button (up-down switch) on the left side of the handle 61a of a periscope 61 is pushed once, a motor M1 is rotated in the direction of an arrow in a solid line and a screw shaft 47 is rotated clockwise through a belt 48 and a pulley 47. Thus, since a moving base 44 is moved to a right side, the two extendible/contractible rods 43 on the right side are pushed, and at the time of being contracted most, a swinging base 41 is started to be pushed. Also, at the time, the two extendible/contractible rods 43 on the left side are in an extended state. By the force, the swinging base 41 is inclined forward corresponding to the turning of a link 42.  When an inclination angle becomes 15 deg., a photosensor is shielded by a dock provided on the moving base 44, the final end of the forward inclination of the swinging base 41 is detected and the motor M1 is stopped through a controller.

Title: X-ray breast photographing device
Inventor: KAARU KUREGUROU SHIEIDO
IPC: G21K1/04
Filed: 1990-09-06
Abstract: PURPOSE: To optimize the image density of a target object by regulating an X-ray source so that a prescribed radiation intensity is set to a first area where the radiation intensity is lowest, and by damping the radiation intensity directed to a second area where the radiation intensity is larger than a prescribed percent of the radiation intensity of the first area. CONSTITUTION: An X-ray detector 114 produces a signal indicating the X-ray radiation intensity that reaches a detector passing through a target object region. A single detector is substituted by the arrays 116 of strip-shaped detectors, and the accurate positioning operation of the target object by the operator is eliminated. The respective strip-shaped detectors are connected to a controller 118, and the controller 118 converts the X-ray intensities of the detectors inside the arrays 116 into the corresponding electric control signals. The controller 118 selects the lowest read value out of 12 read values as that it corresponds to the highest density target object region, and this read value is used for controlling the kVp of an X-ray tube 50. Thus, the intensity of X-ray energy is set to form a contrast so as to conform to the highest density target objective region.

Title: Unit return type-supply system for pin ball game shop
Inventor: HIGUCHI SADAO
IPC: G07F7/08
Filed: 1989-09-11
Abstract: PURPOSE:To eliminate a work, e.g. a ceiling wiring for intercommunicating a ball polishing room and each pin ball game machine mounting unit, a underground piping, and to sharply reduce an installation cost by a method wherein a fluctuation in an amount of circulating supply balls at each pin ball game machine mounting unit is prevented from production. CONSTITUTION:Balls charged in a strike ball feed tray for a play are bought from each pin ball game machine 10 or a pin ball exchanger 2, located between pin ball game machine units. When a given amount of prize balls are stored in the strike ball feed tray, prize ball discharge operation is stopped and during suspension of a game, balls in the strike ball tray are collected to a ball collecting pail 4 at a pin ball game machine mounting unit 1 and are returned from and supplied to the pin ball game machine 10 again. Thus, since there is entirely no ball brought out from the pin ball game machine 10, no fluctuation in a circulating supply ball amount at the pin ball game machine mounting unit 1 is produced. As a result, once a necessary amount of supply balls is previously held in each pin ball game machine mounting unit 1, a unit of return system in which balls can be returned from and supplied to pin ball game machines independently at each pin ball game machine-mounting unit 1 can be employed. This constitution simplifies the supply equipment of a pin ball game shop.
