Patent JP-S57178444-A (JP)
Title: Optical fiber transmission system
Inventor: SUZUKI MASAHIRO
IPC: H04B10/00
Filed: 1981-04-27
Abstract: PURPOSE:To achieve demodulation by only one photoelectric transducer by transmitting >=2 electric signals, differing in occupation frequency band, by using a single photodetecting element. CONSTITUTION:Signals from (n) units of signal sources 1-1-1-n having different occupation frequency bands drive (n) units of corresponding light emitting elements 2-1-2-n to generate light signals, which are guided to (n) units of optical fiber transmission lines 3-1-3-n. The light signals transmitted through those optical fiber transmission lines 3-1-3-n are coupled by a single photodetecting element on a reception side. The photodetecting element 4 transduces the inputs into elelctric signals, which are amplified by a receiving amplifier 5 at a time, so that an (n)-number of signals are obtained from the same electric signal output terminal 6.

Title: Carrier of printed substrate
Inventor: MURAKAWA TOSHITAKA
IPC: H05K3/46
Filed: 1989-03-17
Abstract: PURPOSE:To absorb the thermal expansion of a warpage-proof plate which prevent a printed substrate from being warped by application of a spring force by a method wherein the one end of the warpage-proof plate is fixed and the other end is supported freely with the spring. CONSTITUTION:A printed substrate P is placed on the predetermined positions of claws 2 and 3 and fixed firmly by pressing members 4. A carrier which holds the printed substrate as described above is made to pass through an automatic soldering machine to solder the printed substrate. At that time, the printed substrate is heated to a high temperature and its center part tends to be warped downward. However, as a warpage-proof plate 5 is provided under the printed substrate so as to touch the printed substrate, the warpage is restricted. Although the warpage-proof plate 5 itself shows thermal expansion, a pressing spring 12 attached to the rising part 8 of the warpage-proof plate 5 supports the warpage-proof plate 5 in such a manner that the expansion of the warpage-proof plate 5 caused by the thermal expansion is relieved to the lateral direction (direction of the rising part), so that the downward warpage of the warpage-proof plate 5 can be avoided.

Title: Cooking paper
Inventor: ITO MITSUO
IPC: A23L5/10
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To see through the state of food stored inside and hold moderate steam transmission quantity by using a thin sheet containing specified quantity of regenerated cellulose fibers and the sheet whose light transmittance is set to a specified value for cooking paper. SOLUTION: The cooking paper fitted for using it for wrapping food in electronic heating is the thin sheet containing more than 50wt.% of the regenerated cellulosic fibers. It is formed so that the light transmittance becomes more than 20%. The vapor transmission quantity of the thin sheet at the time of electronic heating is set to be 0.1-0.5g/cm<2> per minute. Thus, food during cooking use or after cooking can be seen through from outside and inconvenience at the time of using kitchen paper and the like is eliminated. Water absorption ability, hygroscopicity and heat resistance, which the cellulosic fibers originally have, exist and moderate vapor transmission quantity is given. Thus, heating finish which cannot be obtained in a film wrap is realized when the sheet is used for electronic heating.

Title: Wheel correction device
Inventor: TSUJISATO YASUO
IPC: B24B49/18
Filed: 1986-03-22
Abstract: PURPOSE:To make it possible to correct alignment error of a wheel center with high accuracy with a center alignment error correction device for a wheel sued for surface grinding process and the like by applying brake on the rotation of a grindstone for the correction when the rpm of the grindstone exceeds a specified value. CONSTITUTION:While rotating a grindstone 20 for correction at a constant rpm by means of a motor 14, the rotation is braked when its rpm exceeds a specified value by means of the contact of a brake shoe of a flywheel 12 against an inner wall surface of a cap 9. Accordingly, since the grindstone 20 can be rotated at approximately constant a speed regardless of the magnitude of frictional resistance between a wheel to keep peripheral speed differential between the grindstone 20 and the wheel approximately constant, the periphery of the wheel can be uniformly ground off regardless of the wheel thickness. Thus, the center alignment error of the wheel sued for a precision surface grinder or grooving process can be corrected with high accuracy.

     CONSTITUTION: A core metal 5 is inserted into a hollow frame material 1 which functions as a transverse frame piece of the door of a gate or the like. This core metal 5 consists of a main body part 6 of a good conductive material such as copper and a pressure resisting part 7 of a steel material or the like which is fitted into the recessed groove of the main body part 6, and frame materials 1 and 2 are brought into contact with each other so that the pressure resisting part 7 is placed in the side face of the frame material 1, which is brought into contact with the frame material 2 which functions as a longitudinal frame piece, with a width smaller then that of the frame material 2. Pressure is applied to these frame materials, and a current is flowed between electrodes 3 and 4, thereby performing resistance welding. After welding, the mandrel 5 is pulled out. By this method, the quality of the outward appearance of welded parts is improved, and variance of the welding strength is reduced.

Title: Method and device for detecting fault
IPC: G01R31/317
Filed: 1992-03-23
Abstract: PURPOSE:To detect a bridge fault between wirings without adding a fault detecting circuit by determining input logical values for making logical values 1 and 0, respectively, to the combination of the wirings having the possibility of bridge fault, and applying them to an inspection target to measure power source current. CONSTITUTION:For example, adjacent wirings 1, 2, wirings 2, 3 are extracted as those having the possibility of causing a bridge fault between wirings, and input logical patterns for making the logical values to the combinations of the wirings 1 and 0, respectively, are determined by a logical pattern generator 15, and applied to an IC/LSI of an inspection target. The power source current supplied to the IC/LSI is measured 16 and compared with the power source current of the normal IC/LSI containing no bridge fault, whereby the bridge fault between the wirings 1-3 of the IC/LSI of the inspection target is detected. Since the outflow of the power source current from power source to ground is increased when the bridge fault is caused, the fault can be easily detected.

Abstract: PROBLEM TO BE SOLVED: To clean a suppression chamber efficiently and reduce the radiation exposure doses for workers. SOLUTION: When the clear layer at the top of the water 7 stored in a suppression chamber 5 is sent to the outside the chamber 5 by a pump 10, a clad 9 in a pliant condition that adheres around the boundary between a submerged part and an unsubmerged one in the side surface 8 inside the chamber 5 is exfoliated by a scraping tool 15 which moves together with a cart 14 in the side surface 8 inside the chamber 5 and almost all the volume of the clear layer at the top of the water 7 is sent to the outside of the chamber 5. Afterward, the clad 9 in a pliant condition adhering to the submerged part of the side surface 8 inside the chamber 5 is exfoliated by a scraping tool 15, and then the clad 9 settling out at the inner bottom of the suppression chamber 5 is sent together with the residual water 7 to the outside of the chamber 5 by the pump 10.  These processes save the labor of clad removing and clad unloading and substantially reduce the radiation exposure dose for workers.
