Filed: 1989-08-02
Abstract: PURPOSE:To simplify an optical system and to reduce the cost by providing a means which drives an optical member in an optical system, which converges luminous flux on an irradiated body, eccentrically during optical scanning. CONSTITUTION:In a tandem type optical system wherein only the light emission point of a light source 1 such as a semiconductor laser and the surface of the irradiated body 7 are optically conjugate, a subscanning-directional shift in optical scanning position due to the surface tilt of the reflecting surface of an optical deflector such as a rotary polygon mirror 5 is corrected by making the lens system 2, light source 1, and deflecting element eccentric or rotating them by an actuator 10. Therefore, an optical scan on a recording image, etc., having no irregularity is made and a conventional expensive optical element such as a cylindrical lens and an anamorphic lens need not be used. Consequently, the optical system is simplified and advantageous in cost.

Filed: 1988-08-16
Abstract: PURPOSE:To attain a priority function through the use of a standard medium access control(MAC) LSI by providing a transmission line utilizing rate measuring means and blocking the transmission of a transmission signal from a connection node when the measured transmission line utilizing rate is higher than a preset value. CONSTITUTION:A transmission line utilizing rate measuring circuit 5 outputs the transmission line utilizing rate to a transmission control circuit 7 and a transmission control circuit 7 always monitors whether or not the transmission line utilizing rate exceeds the set utilizing rate. If the measured value exceeds the set transmission line utilizing rate, a transmission signal gate circuit 8 is controlled and the transmission signal from the node connected to a transceiver circuit is not sent to a transmission line 1. Moreover, when the transmission signal from the node is detected afterward, a collision signal generating circuit 9 is driven to send a collision display signal. Thus, it is possible to send a packet with high priority while taking the precedence over other packets, and the priority control is attained by using the standard MAC LSI.

Title: Oblique elevator
Inventor: TANIWAKI FUKUO
IPC: B66B11/02
Filed: 1988-08-17
Abstract: PURPOSE:To enable an easy drainage of a condensed water without using any particular device and operation method by opening a drain pipe in opposition to a drain channel provided along the advancing direction on the obliquely elevating passage bottom face, and providing an exhaust port toward the outside of the elevating passage on the drain channel lower end. CONSTITUTION:The operation of a chilling unit 10 causes a condensed water, and this condensed water runs down the floor side of an elevating passage 1 through a drain pipe 10a. The floor just under the opening side of the drain pipe 10a is provided with a drain channel 1a continuously formed along the running part of a cage 3. Thus, the condensed water falls into the drain channel 1a and flows to the lower side. As the drain channel 1a is provided with an exhaust port 11 leading to the outside of the elevating passage 1 in the lowest part thereof, the condensed water is exhausted out of the elevating passage 1. Thus, there is no need to provide a tank for storing the condensed water on the cage 3, nor to provide a particular drain device within the elevating passage 1. Hence, the drainage is possible during the operation of the cage 3, and no particular operation for drainage is not required.

Abstract: PURPOSE:To eliminate the need for soldering and scrub work, and then enable simultaneous bonding of them by forming Au layers and Sn layers between a semiconductor chip and a sub-mount and between the sub-mount and a heat sink block so that a specific layer thickness ratio may be available and melting the layers to form an Au-Sn alloy layer. CONSTITUTION:An LD chip 1, a sub-mount 2, and a heat sink block 6 are laminated consecutively on a heat stage 10. Then, they are heated at a temperature of 280 deg.C or above with proper weight being applied to the upper surface of the LD chip 1, which melts and diffuses Au layers 3, and 4, an Sn layer 11, Au layer 7, and 8, and an Sn layer 12 respectively in each junction between the LD chip 1 and the sub-mount 2, and the sub-mount 2 and a heat sink block 6, thereby forming AuSn alloys 13 and 14 so that the LD chip 1 may be interfaced with the sub-mount 2 while the sub-mount 2 may be bonded with the heat sink block 6. Since the Au-Sn alloy layers 13 and 14 have a specific thickness ratio (about 3:2) between the Au layer and Sn layer, the layers 13 and 14 becomes an alloy of 80wt.% Au and 20wt.% Sn.
