Title: Wideband circuit
Inventor: SUZUKI HIDEYUKI
IPC: H03F3/30
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To make a cascode connection circuit wide-band by connecting capacitive load to a connection point between input and output transistors. SOLUTION: A capacitative element 13 is connected to the connection point of a collector of an input transistor 12 and an emitter of an output transistor 10. The transistor 12 converts signal voltage from an input terminal 11 into current and it is supplied to the emitter of the transistor 10. Because input impedance seen from the emitter side of the transistor 10 is inductive, it is amplified in a resonance frequency band according to resonance with the element 13, also, peaking takes place and a band is increased. Thus, it is possible to widen a band even when a circuit that is not low impedance is connected to an output terminal 14.  Further, it is possible to widen a circuit even when any kind of a circuit, such as ground, resistance and capacity is connected to the emitter of the transistor 12, the other end of the element 13 or the terminal 14 and also, it is possible to make a narrow-band circuit high gain by optimizing a parameter of each circuit element.

Title: Orthogonal modulator
Inventor: SAWAHASHI MAMORU
IPC: H04L27/12
Filed: 1989-06-30
Abstract: PURPOSE:To prevent the generation of cross modulation and spuriousness by generating the signals of different center frequencies by applying digitally a frequency offset in a base band zone. CONSTITUTION:In a state that input data is brought to band limit and set to instantaneous frequency information by a base band digital signal processing part 1-4, data of an offset frequency corresponding to a center frequency of a channel is added, and signals of different center frequencies are generated in advance in a base band zone. Subsequently, they are added in the base band zone, and thereafter, modulated. In such a way, a multi-carrier frequency can be generated in one orthogonal modulator 1-13, and also, by varying the data of the offset frequency, the signals of different center frequencies can be generated, and since the synthesis in an RF zone is not executed, the generation of cross modulation and spuriousness is prevented.

The carriage part (s) can be driven by utilizing the working force or the reaction directly applied to the carriage part (s).

Title: Drive controlling method of optical device
Inventor: HIGUCHI MASAMI
IPC: G03B27/50
Filed: 1983-09-13
Abstract: PURPOSE:To stop a scanning means inveriably in a specific area and increase the number of copies per minute by controlling the position where the application of reverse driving force to a motor starts. CONSTITUTION:The position detecting circuit 25 of the scanning means detects the rotating speed of the motor 10 by an encoder 11. The movement distance of a lighting device 3 is calculated from the rotating speed. The movement distance is counted up when the device 3 moves forth and counted down when moving back, so that the position of the lighting device in forward/backward movement corresponds to the counted value, one to one. Consequently, the positions of the start of deceleration, application of the reverse driving force, and stop are detected. The stop position is X0-V0<2>/2alpha, where X0 is the distance from a home position, V0 is the current speed, and alpha is acceleration after it. In this case, alpha is a frictional load and varies with time, so the stop position also shifts. The distance X0 and speed V0 are variable and controllable, so as shift in stop position due to the acceleration alpha is corrected by varying at least either of the position X0 where the reverse driving force begins to be applied and the speed V0.

Title: System for converting electric capacitance value into voltage value
Inventor: OBATA ATSUSHI
IPC: G01R27/26
Filed: 1982-09-27
Abstract: PURPOSE:To convert an electric capacitance value into a voltage value simply and accurately by employing a fixed capacitance condenser and an arithmetic amplifier. CONSTITUTION:A fixed capacitance condenser 1 with a capacitance C1 to which a constant voltage E of a constant voltage generator 4 is applied and a condenser 2 with a capacitance C2 feedback connected thereto are connected to an inversion input terminal 6 of an arithmetic amplifier 5. When the amplification factor of the amplifier 5 is amply large as against 1, the voltage e0 at an output terminal 7 of the amplifier 5 is eo=EX(C1/C2), hence inversely proportional to the capacitance C2 of the condenser 2. Thus, electric capacitance can be converted directly into a voltage value simply and accurately without conversion through a freguency.

Filed: 1979-12-25
Abstract: PURPOSE:To enable the labor for collating of originals to be saved by performing one-side or both-side copying by sending out the stacked originals from the uppermost or lowermost position. CONSTITUTION:Now if it is assumed that 6 kinds of one-side sheet originals O are going to be copied to each 4 sheets, the originals O are successively set on a setting  platen 26. When the operator pushes a copying start button after setting the number of copies to 4 sheets with a dial, the original of the 1st page is conveyed up to the normal position on a transparent original platen 9 where it stops and the downward facing original surface is scanned by optical systems 10-15, whereby an image is formed on the surface of a photosensitive drum 4. In a transfer section 7, the image is transferred to the transfer paper P from a transfer paper containing section 16. After the transfer paper P is fixed 17, it enters the rack 66a of the uppermost stage through a guide passage 64. The copies of the 2nd-4th sheets successively enter the racks 66b-66d. The next original is transferred in a similar manner, after which the copies are put into the racks 66a-66d, hence the finished copies have already undergone collating at that time and this enables labor to be saved.
