IPC: A63F7/02
Filed: 1988-08-11
Abstract: PURPOSE:To prevent prize pinballs from being discharged below a regular number of them through beings so operated that they are surely discharged when a pinball is a safe hit and to improve the reliability of a game machine itself, by a method wherein it is detected that the prize pinballs are normally held, since a detecting device is in the state of operating when at a first position; while it is detected that they are not normally held, since the detecting device is not in the state of operating when at a second position, and a unit for disposing of safe pinballs is stopped. CONSTITUTION:When a response continues above a specified period of time by receiving light, it is detected by being in the state of turning on electricity through a base board 69 for circuits that prize pinballs are correctly held, and since this detected signal is transmitted to a control unit E connected with the base board 69, a unit for disposing of safe pinballs B maintains the normal state of operating by turning on electricity. On the other hand, when a response does not continue above a specified period of time by not receiving light, it is detected by being in the state of turning off electricity that the prize pinballs are not correctly held including the delay of holding the prize pinballs, and since the usual electrical-signal is not transmitted to the control unit E, an electric motor 25 for the unit B is immediately stopped.

Title: Thermal recording material
Inventor: AKIMOTO TAKESHI
IPC: B41M5/26
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To provide high marking properties without fear about the vanishing of an image and the development of color in the white part through contact with a solvent such as plasticizer, oil or ethanol by using an antipyrine complex of zinc thiocyanate as a color developer and also adding salt containing aluminum beyond the solubility in water below a specific temperature level. SOLUTION: An antipyrine complex of zinc thiocyanate is used as a color developer and salt containing aluminum whose solubility for 100g of water at 25 deg.C or less is 0.5g or more, is added to a thermosensitive color developing layer or an undercoat layer. Consequently, the vanishing of an image and the color development of the white part do not occur, if the thermosensitive recording material comes into contact with a solvent such as plasticizer, oil or ethanol. In addition, the material shows outstanding marking properties. When the thermosensitive color developing layer is formed on a support, the antipyrine complex and the salt are preferably added to the thermosensitive color developing layer. On the other hand, if the undercoat is formed, the antipyrine complex and the salt are preferably added to the undercoat layer.  When the aluminum is contained in the undercoat layer, it is possible to prevent blushing from occurring on the coating fluid by a heat-sensitive liquid and reduce texture fog.

Abstract: PURPOSE:To improve the accuracy of discrimination of quality by obtaining clear raw image data by differentiating the raw image data obtained by picking up an image of the surface of an object of inspection by a plurality of image pickup cameras, and by binary-coding those data at different levels. CONSTITUTION:A first camera 53a picks up an image of the outer surface of an object (tube) of inspection from a prescribed disposition. When it picks up an image of an extraneous matter, an analog signal corresponding thereto is generated from CCD of the camera 53a. When this signal is differentiated by a differentiating circuit 1a, variation in the lightness is large in the circumference of the extraneous matter and, therefore, the boundary between the extraneous matter and the circumference is distinct. Moreover, an absolute value of a differential waveform is taken by an absolute value circuit 2a and stored in a first area 4a of a raw image memory 4. These image data are binary-coded by a binary-coding processing part 5 and level setting is executed for the binary- coded data at an appropriate level. The binary-coding is executed so as to conduct determination of quality for various defective forms of a part to be inspected. The binary-coded image data stored in a binary memory 6 are subjected to the determination of quality in a quality determining part 7.
