Title: Light guide type access coupler
Inventor: YAMAZAKI TETSUYA
IPC: G02B6/34
Filed: 1983-01-19
Abstract: PURPOSE:To set a branch output ratio to a desired value with high precision and to reduce branch part loss by forming a V-shaped pattern in a transparent substrate and providing a main light guide path which has a larger refractive index than the substrate, and leading out branch paths from the V-shaped bottom part through a filter and from the middle of a projection path. CONSTITUTION:A light guide path which is circularly sectiolned has such a refraction index distribution that the refractive index is maximum at the center part and decreases parabolically toward the outer circumference in a section perpendicular to an optical axis. The light transmittivity of a filter film 14 is so selected that outputs are at the desired branch ratio on the condition of an angle theta1. A light signal transmitted by an optical fiber 20A is transmitted through an incidence path 11A, transmitted partially through the filter film 14 at the V-shaped bottom part 13, and transmitted to a terminal equipment, etc., through an optical fiber 20C. The remaining transmitted light reflected by the filter film 14 passes through a projection path 11B and is transmitted to a trunk line fiber 20B. A signal which is processed again by the terminal equipment and transmitted through an optical fiber 20d is incident to a branch light guide path 12 and mixed with the trunk-line signal in the projection path 11B.

Title: Method and apparatus for glow discharge processing
Inventor: ASAHI NAOTATSU
IPC: C21D1/38
Filed: 1978-01-27
Abstract: PURPOSE:Prior to glow discharge between a cathode to be treated and an airtight container anode, a separately installed cathode is used to preheat the cathode to be treated by glow discharge, through which process various configuration surfaces are treated with evenly distributed temperature. CONSTITUTION:In glow discharge between the air-tight container wall 1 as an  anode and objects to be treated as cathodes 2, intermediate laminated cathodes such  as Ni plates 7 are placed between the electrodes 1 and 2. First, glow discharge is generated between the intermediate cathodes 7 and the container anode 1 to preheat the objects to be treated 2. Then, while keeping the intermediate cathode 7 activated or turned off, glow discharge between the anode 1 and the objects 2 is initiated to treat the surfaces of the objects 2. The process effectively reduces temperature variations of the objects regardless of configurations, resulting in welltreated objects. In addition, the process essentially prevents arc discharge, thereby effectively eliminating surface roughening of the objects.

Title: Device and method for automatically generating running operation schedule
Inventor: NONAKA HIRONOBU
IPC: G06Q10/06
Filed: 1995-01-20
Abstract: PURPOSE: To precisely and efficiently obtain a running operation schedule adjusted to results by making result information into patterns by individual running date attributes, generating a running operation model and generating a time schedule. CONSTITUTION: Since the running pattern of an equipment has possibility that it changes every day, a running date attribute setting part 1 previously sets it as a running date attribute. When an operator individually executes a running operation and not when he executes a running operation which is previously scheduled, an individual running operation results collection means 2 stores the operation content of the operator in a running operation results storage part 3. If a running operation modeling means 4 is started by the operator when the appropriate number of results is collected for the respective running date attributes on the equipment unit being an individual running operation object, the running operation results whose running date attributes are the same are taken out as the processing objects, and the pattern of the running operation of one day is generated.  Time when the running operation is actually executed is put together at the time of a designated interval so as to adjust it. Then, the schedule of the running operation of one day is generated.

Title: Digital signal reproduction system
Inventor: HAYASHI HIDEKI
IPC: G11B20/14
Filed: 1995-01-20
Abstract: PURPOSE: To reproduce a digital signal at low error rate by correcting the phase of reproduced clock signal based on the value samples during the edge section of a record signal when record signals having run length longer than a predetermined length are read out continuously. CONSTITUTION: An optical pickup 1 performs photoelectronic conversion of a reflected light from an optical disc 3 to produce a read-out signal (a) which is delivered to an A/D converter 21. The converter 21 delivers a sample value q, obtained by sampling the read-out signal (a) at the timing of a reproduction clock signal V from a clock generator 22, to a decoder 23, a phase error generation circuit 24 and a long run length detection circuit 25. The decoder 23 comprises a Viterbi decoder, for example, which captures the sample values (q) being fed sequentially from the A/D converter 21 in the form of a continuous time series of sample values and decodes them to produce reproduction digital signals comprising '1' or '2'.  Based on the sample values (q) being fed from the converter 21, the long run length detection circuit 25 detects a section where record signals having run length longer than a predetermined value are read out continuously and delivers a run length detection signal (r) to a phase signal error generation circuit 24.

Title: Manufacture of synthetic resin laces
Inventor: EYAMA HIROO
IPC: B29C41/00
Filed: 1978-01-26
Abstract: PURPOSE: To manufacture synthetic resin laces free from burrs on the opening parts, by forming a heat-resistant resin layer having releasability and a higher specific heat then the metal constituting a mold on the mold protrusions.  
     CONSTITUTION: A pasty resin is filled in the depressions of the mold by the resin feeder 3, and scraped by the doctor knife 5. The resin is then changed into a semi- gel state by the heater 6 and 6' as the mold 4 proceeds. If only the heater 6 inside the mold 4 is used, the paste remaining in the mold protrusions changed into an insufficient semi-gel state because the heat from the heater 6 is intercepted to some extent by the heat-resistant resin layer 2 having a high specific heat. The paste in a semi-gel state has a low strength and releasability, and the resin remaining on the protrusions can be easily released from the mold 4 and fused to the roll 7.

Inventor: HAMAMURA MASUZO
IPC: B05B7/18
Filed: 1985-01-18
Abstract: PURPOSE:To reduce the load of arc and to melt continuously and reasonably a metal in large quantities by placing the arc melting zone under negative pressure and lowering the temp. of an injection air current as low as possible. CONSTITUTION:In the thermal spraying method of a molten metal used for manufacturing a precision metallic mold, a conical pipe 2 is placed concentrical ly in a thermal spraying cylinder 1 with an intervening clearance 5. A low-temp. compressed gas A is injected from the clearance 5, and a wire 11 for thermal spraying is melted electrically in the negative pressure zone 25 generated at the inside. Consequently, the molten metallic liq. body Q is sucked into the focus of the injected gas current A and crushed to form a branched fine particle having complicated protrusions. The fine particle is collied onto a body to be sprayed by the quenching action of the low-temp. injected gas current A and its high speed. The protrusions of the fine particles are meshed and com bined with the protrusions of the adjacent fine particle. The wire to be melted is thus overheated to some extent in the high-pressure gas current, the pressure is simultaneously reduced and the particle is cooled.
