Title: Envelope sorting device
Inventor: NAKAYAMA HIDEO
IPC: B65H29/66
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To provide an envelope sorting device capable of easily recognizing an envelope sorting place, when the sealed envelope is discharged onto a belt conveyor in an enclosing/sealing system, and capable of introducing the device extremely inexpensively. SOLUTION: This envelope sorting device is for sorting sealed envelopes and for discharging them.

Title: Memory card device
Inventor: YOSHIDA SHOZO
IPC: G06K17/00
Filed: 1986-10-23
Abstract: PURPOSE:To prevent a trouble that even though a memory card is inserted, the insertion thereof is not discriminated by forming a means for detecting the inserting position of the memory card to a connector by one light emitting means and two light receiving means. CONSTITUTION:When the memory card is inserted into the connector, it reaches a first light receiving means 12A or 22A at first, and when further the insertion is continued, it reaches to a second light receiving means 12B or 22B, and when the outputs of both light receiving means substantially coincide, or when the output of the second light receiving means 12B or 22B is larger than the first light receiving means 12A or 22A, the insertion is detected. Since the second light receiving means is provided and the outputs are compared to detect the inserting position of the memory card, even when the output of the light emit ting means is deteriorated, the photoelectric transfer ratio is deteriorated or dust sticks to them, it is difficult to produce an error in detecting the insertion and the reliability is improved.

Abstract: PURPOSE:To eliminate the unstability of performance such as the aggravation of interlace, etc., by providing a vertical oscillation circuit which performs an oscillatory operation synchronizing with a vertical synchronizing signal and a sawtooth wave generation circuit and driving the sawtooth wave generation circuit by an output voltage with the same pulse width as that of the vertical synchronizing signal when the vertical synchronizing signal is impressed. CONSTITUTION:The vertical synchronizing signals (a) and (b) are impressed on the vertical oscillation circuit 1 and the input terminal on one side of a two-input OR circuit 2. Meanwhile, the output signal (c) of the vertical oscillation circuit 1 synchronized with the vertical synchronizing signal (a) is impressed on the input terminal on the other side of the OR circuit 2. The output terminal of the OR circuit 2 is connected to the driving terminal of the sawtooth wave generation circuit 3. At this time, it is possible to set the pulse width of the output voltage of the OR circuit 2 same as that of the vertical synchronizing signal by setting the pulse width of a vertical oscillatory output signal narrower than that of the vertical synchronizing signal. Also, when no vertical synchronizing signal exists, the output signal of the vertical oscillation circuit 1 is impressed as it is. Therefore, it is possible to realize a vertical deflection device with high stability with simple circuit constitution.

Filed: 1988-10-05
Abstract: PURPOSE:To prevent shortening a life and breaking of a circuit part by stopping or weakening a transmitting operation of an inverter as soon as a discharging lamp comes close to its life end and in the case that a plurality of discharging lamps exist, to make it possible to light the rest of discharging lamps by removing the discharging lamp. CONSTITUTION:When a discharging lamp H1 comes close to its life end and becomes difficult to discharge, electric current of a preheating circuit Y1 increases. The increase is detected by a transformer TF1 for preheating current detection and transmitting operation of an inverter circuit CC1 is stopped or weakened for a prescribed period by a protecting circuit CC2. After the prescribed time passes, the stopped state is released and when installation continues, stopping operation is repeated, and when the discharging lamp is removed and the rest of discharging lamps H2 are normal, the circuit CC1 continues transmitting operation and is lighted. Installation of each discharging lamp can be detected by detection of electric current of a preheating current detecting circuit so a discharging lamp lighting apparatus to carry out centralized control of many discharging lamps can be obtained.
