Title: Method and device for connection between optical fiber and optical waveguide
Inventor: KASHIWAZAKI AKIRA
IPC: G02B6/26
Filed: 1990-10-01
Abstract: PURPOSE:To improve the efficiency of coupling between the optical fiber and optical waveguide by forming a core end surface of the optical fiber in a curved concave surface shape and charging an adhesive made of a material which has a higher refractive index than the core between the optical fiber end surface and an optical waveguide end surface. CONSTITUTION:The end part of the optical fiber 1 is dipped in an etchant of fluoric acid and etched to form the end surface of the core 11 in the curved concave surface shape. The end surface of the optical fiber 1 and the end surface of the optical waveguide 3 are adhered and fixed by using the adhesive 5 and then the connection between the optical fiber 1 and optical waveguide 3 is completed. The adhesive 5 is a transparent adhesive and has the higher refractive index than the core 11 of the optical fiber 1. The space A formed between the concave end surface 15 and the end surface of the optical waveguide 3 is filled with the adhesive. Consequently, the adhesive 5 operates as a convex lens to light guided in from the core 11 to converge it.

Title: Data selecting system
Inventor: WATANABE YOSHIO
IPC: G06F15/173
Filed: 1986-11-07
Abstract: PURPOSE:To select valid data out of redundant information just through the function of a selecting device by deciding whether the information can be used or not for plant control through the selecting device to recognize the number of valid data without obtaining the number of valid data from the number of CPUs. CONSTITUTION:When a plant generates a phenomenon to be controlled, the information on the phenomenon is sent to a transmission line by a system together with a unique number (phenomenon occurrence number). If a function A works with said phenomenon, the CPUs 8 and 10 which can execute the function A supply the relevant information to carry out the function A. Then the CPUs 8 and 10 add the phenomenon occurrence number equal to the input data to the processing result of the function A. Thus data is sent to a selecting device via a transmission line. The selecting device controls the allowable time covering from the generation of the phenomenon to the output of the control information and counts the processing results of the function A obtained within said allowance time in the form of valid data to perform decision by majority.

Filed: 1989-10-11
Abstract: PURPOSE:To conform the rotational speed of a machining roll and the feed rate of a material to be machined while delivering the material to be machined as being held so as not to be affected by force deflecting the material to be machined by installing a pair of feed rollers forwarding the material to be machined on both sides of the machining roll so as to be turned while being synchronized with the machining roll.

Title: Substrate transport method in semiconductor manufacturing device
Inventor: MAKITANI MASAHIRO
IPC: B65G49/07
Filed: 1992-09-08
Abstract: PURPOSE:To improve the substrate transport efficiency and operation ratio of a semiconductor manufacturing device by setting work unit time base on the longest process time in a plurality of processing processes and setting the processing cycle of each process as a work unit time. CONSTITUTION:The work unit time (the required time interval from the start of a certain process until the start of the next process) of the transport system of a semiconductor manufacturing device is set based on the maximum value of the processing time of a preheating chamber 15 and a first, second, and third film forming chambers 17, 19, and 21. Substrate feeding to the chamber 15 from a loading-side substrate preparing chamber 11 by means of a second transport machine 13 is performed at the interval of the set work unit time and the substrate processing cycle including the transport time to the chambers 15 and 17, 19, and 21 is set to the work unit time. Therefore, since the time from the feeding of each substrate to the carrying out of the substrate after processing becomes constant, the heat history of each substrate becomes constant and the nonoperating state of the manufacturing device is reduced. As a result, the transport efficiency and operation ratio of the device are improved.

IPC: H01L21/52
Filed: 1994-10-28
Abstract: PURPOSE: To accurately make a pickup when die-bonding to enhance a manufacturing yield by preventing a separation of a pellet by extending a UV-curing dicing tape to remove a disorder of an alignment of the pellet in an assembling step of a semiconductor device. CONSTITUTION: A dicing tape comprises a three-layer structure having: a UV- curing adhesive layer 1 on an utmost layer; a tape basic layer 2 composed of a material having small ductility on an intermediate layer; and a tape basic layer 3 composed of a material having large ductility on a lowermost layer. A cutout is made up to a center part of the tape basic layer 3 by a dicing blade 5. A UV light 6 is emitted to reduce an adhesive force of the adhesive layer 1 to extend the dicing tape. At this time, a pellet 4a is powerfully fixed to the tape basic layer 2 having small ductility to extend only the tape basic layer 3 having large ductility, therefore a disorder of an alignment of the pellet 4a does not generate.

Title: Magnetic recording and reproducing device
Inventor: OKAMOTO TORU
IPC: G11B15/093
Filed: 1984-12-17
Abstract: PURPOSE:To stop a tape at an accurate position regardless of the rest of the tape on a reel by reversing a reel turntable by the number of its inertial turns and stopping the tape. CONSTITUTION:The 1st reverse counter 12 counts reel pulses after the 1st stop signal is generated. A detecting circuit which is not shown in a figure detects the output of a reel pulse generating circuit 6 not being generated for a certain period and a command for low-speed reversing is supplied to a capstan driving circuit 10 in response to the detection output. The 2nd reel pulse counter 13 counts the output of the circuit 6 during this reversing period and a relative operating element 14 detects the coincidence between the counted values of the counters 12 and 13. Then, a control signal generating circuit 9 is driven with its detection output to generate the 2nd stop signal which stops a motor 11 completely. Consequently, the tape is stopped at an accurate position regardless of the rest of the tape.

Title: Optical pickup
Inventor: KONO HARUHIKO
IPC: G11B7/12
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To effectively conduct heat from a light source having a large heat generating value to a first light source mounting part by enlarging the size of the first light source mounting part for mounting a light source of larger heat generating value for enlarging the heat capacity of the entire first light source mounting part. SOLUTION: A light source mounting part 8f is formed smaller than a light source mounting part 1f of a first package 1. That is, the size of the light source mounting part 1f is larger than that of the light source mounting part 8f for extending heat capacity of the light source mounting part 1f, and effectively conducting heat generated in a light source 2 to the light source mounting part 1f. Thereby, the heat generated from the light source 2 is emitted to the light source mounting part 1f through conduction. And heat emission through conduction from the light source mounting part 1f to the base 1a or a sidewall 1b, and heat emission through radiation from the surface of the light source mounting part 8f can be used in larger proportion, which enables effective emitting of heat from the light source 2 having larger heat generating value.
