Filed: 1990-01-29
Abstract: PURPOSE:To prevent the deterioration of a characteristic by oscillating more stably a semiconductor laser by providing a photoabsorbing body on the whole side face excluding the optical faces of a first and a second polarization beam splitters. CONSTITUTION:The respective optical faces of a first and a second polarization beam splitters 16, 17 are left, and to the whole side face of each of them, a photoabsorbing body 21 made of a black resin such as acryl and ABS, etc., is fixed with an adhesive agent.

Subsequently, both end faces of a permanent magnet 20 and the connecting face of both the holders 18, 19 are formed integrally with an adhesive agent. In such a case, the plane of polarization of a first splitter 16 and a second splitter 17 is stuck by inclining it by an angle corresponding to the rotation angle of the plane of polarization by a Faraday rotor. Next, by selecting the length of the rotor 15 as length for rotating the plane of polarization of light which is made incident by an external magnetic field by 45 deg., both the splitters 16, 17 are fixed each other to an extinction ratio by which its deflection surface rotates by about 45 deg..

Title: Laser wavelength converter
Inventor: TAKEHISA KIWAMU
IPC: G02F1/35
Filed: 1993-02-05
Abstract: PURPOSE:To enable wavelength conversion with high efficiency even in the case of execution of wavelength conversion of high-output laser beams by making the laser beam shaped into a linear shape incident on a nonlinear optical crystal having a race track-shaped section. CONSTITUTION:The nonlinear optical crystal 1 is formed to the race track shape in its sectional shape. The laser beam 2a which is a basic wave prior to incidence to the nonlinear optical crystal 1 passes a cylindrical lens 3a and while the laser beam is converged only in its lateral direction, the laser beam is made into the laser beam 2b which is condensed linearly into the nonlinear optical crystal 1. The laser beam 2c subjected to the wavelength conversion is thereby generated. The laser beam 2c is L to return to a circular shape like the laser beam 2b by passing a cylindrical lens 3b. An O-ring can be brought into tight contact with the nonlinear optical crystal 1 having the race track-shaped section and, therefore, the leakage of cooling water does not arise even if this crystal is made into a structure to cool its outer peripheral surface with water. Then, the cooling capacity is increased and the dealing with the high output is possible.

Abstract: PURPOSE:To make the repeater in duplicate by receiving optical repeater output information and drive information of an excitation laser diode with a monitor controller, discriminating whether a fault resides in the transmission line or the laser diode and selecting a standby circuit. CONSTITUTION:Upon the receipt of output information from an optical repeater output monitor 400, a monitor controller 201 receives drive information of an excitation laser diode from a drive circuit 302 of an excitation laser diode main circuit 300.

Title: Received data accumulation system
Inventor: FUKUDA MITSUTOSHI
IPC: G06F3/06
Filed: 1988-01-28
Abstract: PURPOSE:To prevent data disappearance due to system down by performing the double buffering of data having made into a block in a buffer, and in addition, writing it in a file asynchronously with operation such as data receiving and blocking. CONSTITUTION:After a receiving task 2 writes a data unit received from a communication line 1 in a data unit part 3-3 in the buffer 3, it puts forward a data pointer 3-2 in the block, and when vacancy comes to be gone in the buffer 3, it sets the block serial number 4-1 of an auxiliary buffer 4 to be the serial number next to the block serial number 3-1 of the buffer 3, and writes the following data in the auxiliary buffer 4. When the auxiliary buffer 4 comes full as well, the receiving task 2 switches similarly the buffer to the buffer 3. On the other hand, a writing task 5 stores the contents of the buffer 3 and the auxiliary buffer 4 in the position of the file 6 shown by respective serial numbers 3-1, 4-1 asynchronously with the receiving task 2. Thus, even if a receiving system falls down, all the data never disappears.

Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent the particles of developer from getting coarse due to sliding frictional heat with a bearing part by providing a supporting member made of metal for supporting one end of a stirring and supporting member in a longitudinal direction on the bearing part of a developing container. SOLUTION: A parallel pin 5 made of metal (for example, stainless or copper or the like) functioning as the supporting member is press-fit and fixed at either end of the stirring and supporting member 2 in the longitudinal direction on a non-driving side. The pin shaft of the pin 5 is supported by the bearing part 137 provided in a toner container 131. While toner is stirred and carried, the pin 5 receives driving force by a transmission shaft 135 together with the member 2 at the bearing part 137, is rotated to slide, and generates heat. However, the heat conductivity of the pin 5 is higher than the stirring and supporting member made of resin (plastic), so that the sliding frictional heat with the bearing part 137 is efficiently radiated. Therefore, such temperature rise that the toner existing near the bearing part 137 is fused and fixed is restrained.

Abstract: PURPOSE:To ensure a dynamic range of a final bit by setting a cross pint between a leading of a 1st clock voltage of a horizontal transfer section and a trailing of a 2nd clock voltage to a level larger than an intermediate level of a peak value of the clock voltage. CONSTITUTION:Biphase clock voltages phiH1, phiH2 are fed from a clock generator 12 to a solid-state image pickup element CCD 10 via a horizontal transfer driver 11.

Thus, the transfer of a signal charge from a transfer electrode of a pre-stage bit to a transfer electrode of a final bit is implemented at a low potential. Thus, a charge advance event is surely prevented and the dynamic range of the final bit is relatively increased.
