Title: Image forming device
Inventor: KITAMURA MASAHIKO
IPC: G03G15/16
Filed: 1993-09-14
Abstract: PURPOSE:To form an excellent quality image on both surfaces of a paper sheet by preventing fogging toner from being transferred on the surface of a roller, in an image forming device provided with the roller guiding a transfer paper in the vicinity of a position where an electrostatic latent image holder faces a transfer device. CONSTITUTION:The large diameter parts 17a and 17b abutted on the surface of the nonimage part of the electrostatic latent image holder are provided on both end parts of a conductive roller 15 and the outside diameter of the large diameter part 17b located opposite to the side of a side resist is set larger than that of the other large diameter part 17a. Moreover, the large diameter part 17a of the side resist side is constituted of a member whose friction against the surface of the electrostatic latent image holder is smaller than that of the large diameter part 17b of the opposite side. Thus, when a small-sized paper is used, the gap of the side where the paper does not pass is adjusted slightly wider than that of the opposite side, the transfer of the fogging toner can be prevented and simultaneously, the abrasion of the large diameter part 17a of the side resist side can be prevented as well.

Title: Wavelength control distributed bragg-reflector semiconductor laser
Inventor: MURATA SHIGERU
IPC: H01S5/0625
Filed: 1986-10-22
Abstract: PURPOSE:To obtain a title laser, which is capable of controlling precisely the wavelength, is stably actuated in a small size and moreover can be easily manufactured, by a method wherein the effective refractive indexes of a distributed Bragg reflector (DBR) part and a filter part are changed by injecting carriers in these parts and are corrected by just adding a simple feedback circuit. CONSTITUTION:The transmittance of light of a specified wavelength incident through a DBR part 200 is changed by injecting carriers in a filter part 300. This matter adversely can monitor the fluctuation of an oscillation wavelength by a method wherein the transmission characteristic of a filter is electrically controlled and fixed in a certain state and the amount of transmitted light is received. Accordingly, by controlling the injected current of the DBR part 200 in such a way as to keep the light-receiving level at a constant value using an electrical feedback circuit, the oscillation wavelength can be kept at a constant value. The stability of the wavelength can be stabilized in 0.3 nm or thereabouts, and moreover the control extent of the wavelength also can be controlled over several nm or more of the roughly same degree as the wavelength variable extent of a laser.

Title: Magnetic head
Inventor: ITOU KAZUMA
IPC: G11B5/265
Filed: 1983-12-27
Abstract: PURPOSE:To enhance the recording density and to obtain a magnetic head, which has not an erase gap to have a simple constitution, inexpensively by providing a write gap and a read gap apart from each other and setting the width of the write gap to a value smaller than an allowable off-track quantity. CONSTITUTION:A write gap 8 is formed in a core 7 around which a coil 6 for write is wound, and a core 10 around which a coil 9 for read is wound is provided back to back with this core 7, and the width of a read gap 11 provided in the core 10 is set to a value smaller than the allowable off-track quantity. The width of data A written on a track -x off the track is reduced to (l0-2x) if data B is written adjacently to this data A +x off the track, and it is necessary that these data are read out without errors by a head +x off the track. Therefore, the write gap width l0 and a read gap width d0 must satisfy relations l0= x+l0/2+d0/2+x, namely, l0=4x+d0. Consequently, when the read gap width d0 is set to a value smaller than the allowable off-track quantity (x), the track pitch is shorter than that of a conventional head, and the recording density is enhanced.

Title: Facsimile sub-scanning system
Inventor: BABA MASAYOSHI
IPC: H04N1/17
Filed: 1984-11-29
Abstract: PURPOSE:To eliminate irregular printing to prevent recording and reading-out under transient state of sub-scanning speed by providing the first and second storing means in which facsimile signals are stored alternately. CONSTITUTION:When starting to transmit an original, a control part 13 starts to sub-scan while controlling a motor driving part 24. The read-out facsimile signals are stored in a storage part A or B alternately. Simultaneously with the storing completed, the control part 13 makes a transmission control part 10 start to transmit, while specifying transmitting address. When completing the transmission, the control part 13 judges that the storage parts A and B are empty and switches a motor 4 to a sub-running speed mode. After the fixed period, it commands a reading-out part 8 to read-out by returning again the motor to the normal running-constant speed mode. In the case of reception, the same process as stated above is proceeded. When the storage part A or B is filled, recording is started, and when empty, the motor is set to the normal running-deceleration, and then to the reverse running-stop mode. After the other storage part is filled, recording is started again by switching the motor from the sub-running speed to the constant speed mode.

Title: Synchronous circuit device for external synchronous camera
Inventor: NEMOTO KENICHI
IPC: H04N9/475
Filed: 1994-10-19
Abstract: PURPOSE: To facilitate the configuration of a system comprising plural color television cameras of external synchronous system by forming an internal synchronizing signal and an internal synchronous subcarrier signal based on a synchronization reference signal signal received externally. CONSTITUTION: A synchronizing separator circuit 21 in a synchronous circuit device 10 extracts a synchronization reference signal from a signal received externally and an internal synchronizing signal generating circuit 31 uses a PLL circuit to generate internal vertical synchronizing signal and horizontal synchronizing signal in phase to the synchronization reference signal. Then a subcarrier oscillation circuit 41 generates an internal oscillated subcarrier whose phase is equal to the horizontal synchronizing signal based on the internal horizontal synchronizing signal. When a burst signal is included in the external synchronization reference signal, a separate circuit 25 separates the burst signal and a subcarrier generating circuit 61 generates an internal synchronous subcarrier.  Thus, it is possible to activate a television camera accurately and automatically synchronously with the external synchronizing signal and a system using plural color television cameras of external synchronous system is easily built up.
