Title: Automatic vending machine
Inventor: ASANO KINYA
IPC: G07F9/00
Filed: 1988-05-20
Abstract: PURPOSE:To permit the sale of commodities of a prescribed maker only by using an identifying information memory part, a stopper for feed of commodities, a means which drives and controls the stopper, and a means which disables the reuse of an information medium. CONSTITUTION:When the commodities are put into a commodity carry-in/carry- out part 6, an information reading means 2 reads the identifying information obtained from a distribution case or a package storing the commodities. This read information is collated with the identifying information stored in a memory part 4 for medium information, etc., via a microprocessor 1. Only when the coincidence is obtained between both identifying information, the mode of a stopper means consisting of a stop lever 16, etc., is released by the control means of a solenoid 17. Thus the sale of a commodity 14 is permitted. A magnetic card is erased by an erasion head 2h after reading and punched by a punching device 2j. Thus the identifying information on the card is destroyed and the reuse of the card is disabled. As a result, the sale of commodities of other makers is impossible via an automatic vending machine. Then the sales of a due maker is secured in accordance with the number of sold commodities.

Title: Brushless self-excited synchronizing generator having salient-type rotor
Inventor: KONDOU SEIJI
IPC: H02K19/26
Filed: 1979-09-24
Abstract: PURPOSE:To reduce noise due to the wave-form of an output voltage by connecting rectifying devices in series to an interpole auxiliary winding to form a half-wave rectifying circuit. CONSTITUTION:The auxiliary winding 11 of interpoles 10 and 10 is set so that it delays by 90 deg. in phase by a field winding 8. Therefore, a current flowing therethrough, that is, an auxiliary current If0 delays by a phase of about 90 deg. from a field current If. Further, since the winding 11 has a number of turns smaller than the winding 8, the currents have a relationship If>If0. The current If0 is rectified by a rectifying device, and becomes a DC current pulsating at 2omega similarly as the current If. On the other hand, when a phase advancing current Ic+Ico of a capacitor exciting winding 2 gradually increases, the terminal voltage of a winding 2 finally reaches at a voltage estabilishing point. As a result, it is possible to eliminate the waveform strain of the output voltage and reduce noise generated.

IPC: G03G15/20
Filed: 1981-08-03
Abstract: PURPOSE:To prevent the generation of a shock sound by interposing a spring clutch between a driving gear and a cam shaft, and fitting a unidirectional clutch which rotates together with the driving gear in one body. CONSTITUTION:While a press-contacting roller and a fixing roller are in contact, a cam 10 is not rotated and a pivotal driving arm 20 engages a pawl 19 and the power of a driving gear 13 is not transmitted to a cam shaft 11, so that the driving gear 13 and a unidirectional clutch 15 both idle. At the time when the press-contacting roller and fixing roller separate from each other, a solenoid 22 operates as shown by an arrow (f) to allow the pawl 19 to come out, and a spring clutch 14 operates to couple the driving gear 13 with the cam shaft 11. At this time, the cam shaft 11 is to rotate faster than the gear 13 by the force applied to the shaft 11, but the unidirectional clutch 15 engages the shaft 11 to perform braking, so that the cam 10 rotates slowly without rotating abruptly.

Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To obtain a copying machine with an ADF(automatic document feeder) which is improved in operability by suppressing the number of returned documents as small as possible, when a transfer paper is jammed or an interruption copy is made. SOLUTION: The copying machine adopts the document prefeeding system of feeding a document onto a contact glass and prefeeding the next document up to a fixed position by using the fact that the document is under exposure. Then, the timing of starring a prefeeding operation is made different according to a set number of copies. When as a document feeding mode, reverse feeding is obtained, refeeding can not be started. When a copying operation mode is a one-side both-side mode, prefeeding can be started after feeding for a first repeated copy from a double-sided tray for the transfer paper is started.

Abstract: PURPOSE:To perform stable detection of the titled angle with easy constitution by providing a light source, a single polarizing plate fitted to a movable mirror, a divided light detector, etc. and obtaining an error signal corresponding to a turning angle of the movable mirror. CONSTITUTION:Since a combined polarizing plate 5 is a combination of two polarizing plates 5a and 5b whose mutual deviated axial directions go straight on a parting line 6, when the light from the light source 1 is transmitted through the polarizing plates 4 and 5, and the polarizing plates 4 and 5a, a difference takes place on the quantities of the transmitted light beams. These quantities of the transmitted light beams are detected respectively by a two-divided-light beam detector 7 and the error signal is obtained by amplifying differentially an output of the light detector 7 with a differential amplifier 9. Since the error signal is indicated by Sin2thetam (thetam is the turning angle of the movable mirror 3), the turning angle displacement of the movable mirror 3 can be detected.

IPC: G09G3/28
Filed: 1988-05-19
Abstract: PURPOSE:To improve the light emission intensity by making the potential differences between anodes and cathodes larger than the lowest discharge maintaining voltage and smaller than the lowest discharge starting voltage. CONSTITUTION:The potential differences between the anodes 221-224 and cathodes 121-124 are made larger than the lowest discharge maintaining voltage and smaller than the lowest discharge starting voltage, so discharge does not start unless a potential difference which is larger than the lowest discharge starting voltage is generated between the anodes 221-224 and cathodes 121-124. Further, the discharge is maintained after being started by generating a potential difference larger than the lowest discharge starting voltage even if a potential difference larger than the discharge starting voltage is generated. Then the discharge is stopped by generating a potential difference smaller than the lowest discharge maintaining voltage between the anodes 221-224 and cathodes 121-124, and the discharge can be maintained continuously in a period from the discharge start to the stop. Therefore, a diode and a maintaining pulse generating circuit can be omitted and the circuit constitution can be simplified.
