Title: Transfer device in image forming device
Inventor: SAGARA YASUNORI
IPC: G03G21/14
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To shorten a period of printing time especially for a small-sized paper by changing the traveling amount of a photoreceptor belt, in accordance with the size of a sheet to be printed. SOLUTION: In the case the sheet to be printed has A4-size for instance, when the development by a width of the A4-size is completed, the traveling of the photoreceptor belt 1 is temporarily stopped to perform a transfer. This stopping operation is automatically executed at the time when the processing of image data developed at a single developing operation is completed. After this stop, a transfer opposed roller 8 is moved in a direction perpendicular to the carrying direction of an A4-sized paper 9a, to transfer a toner image 7c formed on the belt 1 to the A4-sized paper 9a. After the opposed roller 8 is made to conduct a reciprocating stroke operation, to be returned to a home position, the belt 1 is driven to travel.  When an A4-size positioning mark 13 is detected, the traveling of the belt 1 is stopped and the A4-sized paper 9a is carried by the width of a developing unit and stopped.

Title: Tape recorder
Inventor: ITOU YUUJI
IPC: G11B5/024
Filed: 1981-07-28
Abstract: PURPOSE:To avoid the recording at the head part of a tape, by travelling automatically the tape by a certain extent with an input signal cut off to a recording head after detecting that the tape is not wound around a take-up hub when a recording operation is carried out. CONSTITUTION:A cassette half 1 is loaded with a tape wound throughly around a supply hub 3 and no tape wound around a take-up hub 2 respectively. Thus a photodetecting device 9 detects that no tape 8 is wound around the hub 2 and then produces an output. Then an output is produced at a recording operation commanding circuit 10 that starts the recording operation. An AND circuit 14 delivers an on-signal, and a time setting circuit 11 switches a switch 12 just for a prescribed time. Accordingly a motor which is controlled by the output of the circuit 10 is rotated in a state under which no recording is carried out although the tape 8 abuts on a recording/reproducing head 6. Thus the tape 8 travels with no recording for a prescribed time.

Title: Recording apparatus
Inventor: HIWADA SHIYUUHEI
IPC: B41J2/12
Filed: 1995-05-17
Abstract: PURPOSE: To prevent the erronous operation by the error of recording data caused by noise even if many actuators are driven at the same time and to well perform the transmission of data from a control circuit to a drive circuit. CONSTITUTION: The recording data transmitted from a control circuit receives the addition of redundancy data in an addition part (parity generator) to be stored in the shift register of a drive circuit 21. The output of the shift register is issued to a judging part 4 and a latch 6 and checked in parity in the judging part 4. When the judging part 4 judges that noise is superposed on recording data by the effect of a drive signal on an actuator to generate an error, a return part 43 lets the control circuit know 'abnormal transmission'. The control circuit 21 re-transmits the recording data on the basis of the abnormal transmission. When the recording data is normally transmitted, an output circuit 10 is operated on the basis of the output from the latch 6 to drive the actuator, that is, a printing head.

Title: Gps receiver
Inventor: SASAKI MASAHIRO
IPC: G01S1/00
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To shorten the satellite capture time, without widening a frequency scan range of a GPS receiver. SOLUTION: The GPS receiver comprises a detector 2, a positioning unit 3, a navigation message receiver 4, a backup unit 5, a satellite selector 6 and a geostationary satellite receiver 7. The selector 6 selects a receivable satellite from orbit information in navigation messages and positioning results. A Doppler frequency due to moving of the satellite and an offset frequency due to the oscillator error are added to a set frequency to obtain a scan center frequency of the satellite. Even with the main power being off, a backup power source activates the geostationary satellite selector 6 to receive geostationary satellite signals. Since the offset frequency of the oscillator is always measured, an exact satellite scan center frequency can be set in the selector 6 when the main power is set on. Thus the satellite capture time can be reduced.

Filed: 1989-05-12
Abstract: PURPOSE:To improve an output response speed of photoelectric current while reducing a noise accompanying with avalanche multiplication by constituting a p-type third semiconductor region formed on a second semiconductor region for avalanche multiplication by three layers while forming a middle layer with lower impurity concentration and greater thickness than the upper and lower layers. CONSTITUTION:A semiconductor layer 6 has a semiconductor layer 7a having high-p-type impurity concentration and relatively thin thickness, a semiconductor layer 7b formed on the semiconductor layer and having low p-type impurity concentration and great thickness compared with the semiconductor layer 7a and a semiconductor layer 7c formed on the semiconductor layer 7b having high p-type impurity concentration and small thickness compared with the semiconductor layer 7b. In this case, the semiconductor layers 7a, 7b and 7c consist, for instance, of InGaAs while having a narrow energy band gap compared with a semiconductor region 4 for avalanche multiplification. Thereby, an optical current comes to be accompanied only by very few noises while a response speed until the photoelectric current is outputted to DC load by being incident of light L can be specially speeded up.
