Title: Electrostatic latent image forming device
Inventor: HOSHINO HIROYUKI
IPC: B41J2/395
Filed: 1993-01-07
Abstract: PURPOSE:To provide an electrostatic latent image forming device, which reduces ununiform recording due to the deformation of dots, which is developed by Coulomb's force. CONSTITUTION:When recording medium moves on paper surface from below to above, the voltage V2 of power source 8 is made larger than the voltage V4 of power source 7. Concretely, under the condition that the distance between train electrodes 2 and 3 and the recording medium is 1mm, V2 is set to be 1,150V while V4 is set to be 1,000V. As a result, the influence of the Coulomb's force applied from the dots, which are formed previously, is reduced.

Title: Timing generating circuit
Inventor: NISHIZAWA TEIJI
IPC: G06F1/06
Filed: 1983-02-03
Abstract: PURPOSE:To generate four-phase timing signals-in the same period as an input clock by providing a variable delay circuit and a delay measuring circuit to form output timing signals from decoder outputs. CONSTITUTION:An input clock phiin is inputted to a variable delay circuit 1 and is outputted as an output clock phiout after a delay time determined by a a control input signal CTL. Clocks phiin and phiout are decoded by AND circuits 2-5 to generate timing signals T1-T4. Signals T1-T4 are inputted to a delay measuring circuit 6 and are compared with one another with respect to time, and results are outputted as the signal CTL to the circuit 1. The circuit 1 consists of four-stage inverters fundamentally, but the delay time is controlled because the internal resistance of the transfer gate is changed by the potential of the signal CTL. Thus, the circuit is stabilized in a proper delay state, and four-phase timing signals where the section of the signal T1 and that of the signal T2 and that of the signal T3 are equal to one another are generated.

Title: Data transmission system
Inventor: TANAKA KIYOSHI
IPC: H04L27/18
Filed: 1989-01-30
Abstract: PURPOSE:To simplify the demodulation at the reception side by applying the sum logic conversion to the input data together with a 2nd sum logic conversion to an exclusive OR secured between the output of the 1st sum logic conversion and a signal having a cycle double as much as a clock, and inputting the delay signal of one of both sample data to an orthogonal modulator together with the other sample data to acquire and output an offset signal. CONSTITUTION:The transmission data 1 is converted via a sum logic conversion circuit 3 for acquisition of its exclusive OR to a signal 2 having a cycle double as much as a clock. Then the data 1 is converted again via a sum logic conversion circuit 4 and undergoes the 2-bit sampling via a sampling circuit 5 with a signal having a frequency double as much as a clock. The former one of two bits is directly inputted to the in-phase component of an orthogonal modulator 7. While the latter bit is delayed by one bit by a delay circuit 6 and inputted to the orthogonal component of the modulator 7. Then both bits are transmitted. A reception signal 13 is multiplied by the signal which is delayed by one bit via a delay circuit 14 to undergo the delay detection via an LPF 15. Then a clock is reproduced and also identified by an identifying circuit 17. This identified clock is outputted. Thus, it is possible to simplify the constitution of a receiving device suitable to transmission of short signals.

Title: Cassette mounting device
Inventor: TSUJINO YUKIHIKO
IPC: G11B15/675
Filed: 1990-01-26
Abstract: PURPOSE:To make cassette ejection quantity at the time of large cassette ejection almost same as that of a medium or small cassette and to execute stable operation when the cassette is ejected by providing a cassette ejection quantity adjusting mechanism to adjust the cassette ejection quantity from a cassette insertion port. CONSTITUTION:In the process of cassette unloading, when an outer cassette holder 3 raises a vertical stroke from a cassette loading position by a driving motor and moved to a position where the vertical stroke is moved to a horizontal stroke, this position is detected by an outer mid position detection sensor 58. Only when it is detected by a cassette class detection sensor 56 that the cassette is large, the move of the outer cassette holder 3 is stopped by the cassette ejection quantity control mechanism and only an inner cassette holder 4 is allowed to move from a cassette mount side position Y to a cassette insertion port position X. Thus, when the large cassette is ejected, the ejection quantity from the cassette insertion port can be made almost same as that of the medium or small cassette and the stable operation can be executed when the cassette is ejected.

IPC: H01M4/22
Filed: 1987-01-28
Abstract: PURPOSE:To prevent short circuit caused by piercing a separator in the in- container formation of a non-charged battery by adding ammonium sulfate to an electrolyte.

Abstract: PURPOSE:To make registration turbulence and motor step-out preventable from occurring, by setting the exciting frequency of a stepping motor for regulating plate shifting down to a low value at the time of shifting copying paper to a paper refeed position, in case of a copying machine. CONSTITUTION:When copying paper 81 is loaded on a intermediate tray 58 as much as the specified number of sheets and paper refeed for duplex copying and composite copying takes place, a tip regulating plate is shifted to a home position, then a side regulating plate 63 is shifted from the target position as far as the specified distance and, after another side regulating plate 62 is rocked several times by a solenoid and matched with the former, the side regulating plate 63 is shifted to a target position X2, whereby the copying paper 81 is matched to a paper refeed position. In this case, exciting frequency of a stepping motor shifting the side regulating plate 63 is set to 1/10 or so as usual. Thus, normal regulating plate movement is performed in a short time and, what is more, registration turbulence is preventable from occurring.
