IPC: B25J15/06
Filed: 1988-12-22
Abstract: PURPOSE:To properly suck both a large-sized component and a small-sized component, to prevent an inclined suction operation and a vertical suction operation of the component and to enhance a dimensional accuracy of a mount by a method wherein a shape of a hole in a nozzle suction face is formed to be nearly -shaped. CONSTITUTION:A shape of a hole in a nozzle suction face is formed to be nearly -shaped; its dimensions are e.g. as follows: h=0.7mm; i=0.2mm; j=2.0mm in diameter; k=1.4mm; l=0.35mm; m=0.2mm; n=0.3mm; o=0.2mm; p=0.35mm; q=0.7mm; r=0.8mm; s=1.4mm; t=0.3mm. When a very small rectangular chip component of 1.6X0.8mm is sucked by using this nozzle, an inclined suction state is not caused because a groove width of (i) is smaller than an (f) size value; when an (h) part, an (r) part and a (q) part are installed, a component suction force is enhanced and a dimensional accuracy of a mount can be enhanced.

Title: Sound muting circuit
Inventor: TASHIRO TAKESHI
IPC: H03G3/00
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a sound muting circuit whose target is to make a circuit scale small and to simplify it. SOLUTION: When 12 V and 5 V power supplies are simultaneously started up, an emitter waveform of a PNP transistor Q1 is instantly started up because the 12 V power supply is applied only through a diode D1. In such a case, a base waveform of the Q1 is a charging waveform through resistors R2, R3 and a condenser C2, and turns on the Q1 for certain time after power supply startup. Thus, a muting pulse is supplied to a muting control circuit that consists of resistor R4 and an NPN transistor Q2, while a sound output that is connected to a Q2 collector is grounded for a period to generate the muting pulse so that pop noise that is generated at a sound amplifier output is muted. Although it becomes a discharge operation when power supply is off, a muting pulse is generated from the collector of the Q1 in the same way when the power supply is on.

Abstract: PURPOSE:To return a card to the user securely even at the time of generating an error by providing respective abnormality setting means for discriminating the abnormality of a card detecting means from the abnormality caused by the other cause with a timer.comparing means and a card detecting means. CONSTITUTION:The running state of a card to be carried is monitored by two sensors adjacent to each other, for example, when the next sensor 5d detects it before a sensor 5c which should detect first, the sensor 5c is judged as defective and the sensor defective error code is set. The passing time during these detection and the judgement is compared to the time set by a timer, and when the passing time is longer, even if the sensor is normal, the running error caused by the catch of the card in a running path is set to discriminate the cause of the defection of the running state of the card. Since it is formed to carry the card to a card insertion port after the generation of the error, the card is securely returned to the user independently of the existence of the fault of a card carrying means.
