Title: Optical switch
Inventor: FUJIWARA MASAHIKO
IPC: G02F1/31
Filed: 1986-06-16
Abstract: PURPOSE:To obtain an optical switch which is small in size, in which a light source, photoreceptor, etc., are monolithically integrated in circuit and whose loss variation caused when rays of light are switched to another is small, by utilizing the variation of the refractive index following to the disappearance of an exciton absorption peak. CONSTITUTION:A buffer layer 2, clad layer 3, MQW guide layer 4, clad layer 5, and top layer 6 are successively grown on a base plate 1 and, by etching the layers 6 and 5, crossing waveguides are formed by means of channel guides 7a and 7b. Thereafter, Schottky electrodes 8a and 8b are formed in a symmetrical state and a receiving and emitting end faces are finally formed. When a voltage is applied across the electrodes 8a and 8b, an electric field which is parallel with the layers 2-6 is applied to the gap section between the electrodes 8a and 8b and, when the electric field is applied to the layer 4, an exciton absorption peak disappears and a change in refractive index is induced. As a result, the incident light 9a to the channel guide 7a is totally reflected to the channel guide 7b side due to the induction of a negative change in refractive index of the layer 4.

Patent JP-S63304345-A (JP)
Title: Control system for memory request
Inventor: HASEGAWA TAKASHI
IPC: G06F13/26
Filed: 1987-06-05
Abstract: PURPOSE:To prevent the overrun of a channel having a low priority by inhibiting a memory request that is given to prefetch data before transfer of a write system instruction in case a request factor having a priority lower than said memory request exists. CONSTITUTION:If a channel control part 2A decides a memory request to a write system, the part 2A sets a latch 24 before a prefetching action is started. Therefore a prefetch request 6a given from a memory request circuit 5a is outputted to a priority circuit 10 via a gate 25 and validated. However the request 6a is not outputted to the circuit 10 as long as another request exists. While the latch 24 is reset and outputted when the prefetching action is through. In such a way, the requests are inhibited before transfer of the data on a write system instruction as long as another request of a lower priority exists. Thus the overrun is avoided for another channel device having a low priority.

Title: Writing paper guide
Inventor: NANBA TAKEO
IPC: B65H45/28
Filed: 1989-06-03
Abstract: PURPOSE:To solve the flapping by air of the top end of a writing paper held and brought by a writing paper holding part of the drum of a folding machine by forming a writing paper guide part with a brush hair facing the drum circumferential surface in the state inclined to the adjacent normal of the drum circumferential surface in such a manner as to accord with the rotating direction of the drum circumferential surface. CONSTITUTION:When the top end of a writing paper is flapped by air, the portion largely separated from the drum circumferential surface collides with the side surface of a brush hair 13. However, the part around the top end of the brush hair 13 inclined in such a manner as to accord with the rotating direction of the drum circumferential surface retreats with the inclination being increased, and softens the collision shock applied to the writing paper top end. Additionally, the writing paper top end largely separated from the drum circumferential surface by the flapping is guided to the hair top side while being returned back to the drum circumferential surface side by the inclined side part of the brush hair 13. Consequently, the writing paper is introduced into a gap between the writing paper guide part 12 of a writing paper guide 1 and the drum circumferential surface without any inconvenience.

Title: Heat transfer body for heat exchanger
Inventor: MEN MASATO
IPC: F28D19/04
Filed: 1985-06-28
Abstract: PURPOSE:To prevent the deposit and growth of dust adhered to a heat transfer surface by a method wherein a plurality of heat transfer elements, forming flow path of fluid, are displaced mutually and relatively by an external force, in the heat accumulating type heat exchanger. CONSTITUTION:When fluid is injected while moving a soot blower 7 forwardly and rearwardly in radial direction during rotating a rotor 3, the fluid passes through flow paths between heat transfer plates 4, laminated in a fan type basket 5 through guide plates 6, and a pressure difference due to eddy currents is generated between one surfaces of respective heat transfer plates 4 and the rear side surfaces thereof thereby providing the heat transfer plates with radial alternating external force. The heat transfer plates 4 are arranged with some gaps between neighboring heat transfer plates, therefore, they are vibrated radially and the relative displacement is generated. Thus, the adhesion and growth of dust may remarkably be reduced regardless of the configuration of enlarged heat transfer area of heat transfer element whereby the operation of the heat exchanger may be continued for a long period of time.
