Title: Illegal card detection device
Inventor: KUROI TOSHIO
IPC: G06K17/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To detect a prepaid card on which surface has a tape or the like stuck. SOLUTION: When a card is inserted in a vending machine 30 from an insertion part 31, the card is carried by a card carrier roller 41 and check at an optical/magnetic sensor 50 and read/write at a read and write part 60 are performed. After the read/write at the read and write part 60, the card carrier roller 41 inversely rotates, the card is carrier towards the card insertion part 31 and passes a tape detection part 70. At this time, when a tape or the like is stuck on the surface of the card, an edge surface of this tape and a tip part of the tape detection part 70 are engaged to each other and the tape detection part 70 bends. When a pressure sensor 71 detects a load by this winding, this card is regarded as an illegal card. The detection of the illegal card inversely rotates the card carrier roller again and this illegal card is stored in an illegal card storage part 80.

Abstract: PROBLEM TO BE SOLVED: To enhance charging and discharging use rate of a negative electrode by using a material of which lithium is stored in the negative electrode of the lithium secondary battery and copper particle with its restricted particle size is uniformly dispersed in a dischargable carbon material. SOLUTION: A lithium secondary battery is provided with a positive electrode having a metal oxide as an active material, a negative electrode, a separator, and a presence or absence electrolyte.

Title: Automatic clarifying circuit for ssb receiver
Inventor: SAITOU YOUHEI
IPC: H04B1/40
Filed: 1978-04-24
Abstract: PURPOSE:To secure an automatic clarifying operation by using the locked oscillator which generates the synchronized continuous signals in a steady way by the SSB signals. CONSTITUTION:The SSB signals received through antenna 1 are delivered through speaker 7 via mixer 3, IF amplifier circuit 4, SSB demodulator 5 and others. While locked oscillator 13 receives the SSB signals from IF amplifier 4 and then oscillates with the frequency locked to the frequency of the SSB signal. The oscillated signals are turned into the DC control signals through FM detector 14 to be held at the holding circuit and then applied to variable capacity element 10 to control the frequency of local oscillator 8 in case the change-over switch is switched to automatic side A. The signal of oscillater 8 is applied also to FM detector 17 to generate the fixed DC voltage. The generated DC voltage is then applied to comparator 16 to be compared with the output of detector 14. When the frequency of amplifier 4 varies and the voltage difference exceeds the fixed level, the holding action of circuit 15 is released. And the output of detector 14 is applied to element 10 to vary the frequency of oscillator 8.

Title: Cyclic motion control device
Inventor: KUNII TATSUHIKO
IPC: B65F3/00
Filed: 1988-02-29
Abstract: PURPOSE:To enable a selective control to be performed by a single kind of selective control device removably mounting a detecting member, having a radial detecting part, to a power takeout shaft when its rotary sensor performs the detection, in case of the captioned device for an on-vehicle dust press in- crushing device. CONSTITUTION:When a power takeout shaft 22 is rotated by an oil hydraulic pump 23, a proximity plate 13, having two or more radial detecting parts 13a-13d, rotates. This causes a proximity detecting sensor 24 to generate a signal corresponding to each of the detecting parts 13a-13d. In case of changing the oil hydraulic pump 23 into a pump of the different displacement, when the proximity plate 13 is replaced with a plate having a radial detecting part such that a delivery amount of the oil hydraulic pump per one signal obtains the fixed value, a signal in proportion to the delivery flow amount of the oil hydraulic pump 23 can be input to a selective control device 26 from the sensor 24. Accordingly, a control can be performed by the selective control device of single kind even when the oil hydraulic pump or the like is changed.

Burnt gas exhausted from the established chimney 2 drops inside of the cylindrical body 4 halfway, enters the inside of each of the auxiliary chimneys 5 and again rises inside thereof. At this time, since the speed of flow is suddenly decreased and the direction thereof is also changed, a large amount of dust contained in the burnt gas is removed and the burnt gas relatively cleaned is exhausted outside the incinerator.

Title: Image recorder
Inventor: NAGASHIMA KANJI

Filed: 1994-03-18
Abstract: PURPOSE:To secure a large quantity of transmitted light and to obtain excellent image quality even in the case of overexposed negative film by providing a collimating lens or a collimating mirror for making light which is not made incident on a parallel-beam member parallel beams. CONSTITUTION:The collimating lens 36 is arranged between a condensing Fresnel lens 34 and a light source 16 in an image recorder 30. The lens 36 is arranged near the light source 16 so that its optical axis may be aligned with the optical axis L of an image-formation lens 12, thereby condensing divergent light which directly goes toward an original G from the light source 16 without being made incident on a reflector 32 and making it the parallel beams which are parallel with the optical axis L. The parallel beams are condensed by the lens 34 and radiated as the vertical light to the original G by forming an optical path along the optical axis L. Since the diffused light which is wasted hitherto is condensed and made incident on the lens 12 in such a way, a light component contributing to exposure is increased to excellently record the image even in the case the original G is overexposed.
