Abstract: PROBLEM TO BE SOLVED: To form constant strong-weak perforations even with the fluctuation of depth of sticking unit blades into a sheet by arranging a large number of unit blades each of which has parallel side edge parts and a tip part forming an acute angle, parallel on a straight line, and integrating the base parts of these unit blades by a base part. SOLUTION: A large number of unit blades each of which has two parallel side edge parts 12 and a tip part 11 forming an acute angle are arranged parallel on a straight line, and the base parts 2 of these unit blades 1 are integrated by a base part. The unit blade 1 can be a single-edged one in addition to a double-edged one. In any case, it is desirable that the edge is to have an acute angle, that is, 90 deg. or less. The width of the unit blade 1 and the width of a groove between the respective unit blades 1 can be optionally set. With the unit blade 1 formed in such shape, even in case the depth of each unit blade 1 sticking into a sheet body is slightly different, there is no change in the width of formed openings so as to obtain always constant perforations.

Title: Production of hydrogen sulfide
Inventor: YAMADA NOBUHIRO
IPC: C01B17/16
Filed: 1988-08-17
Abstract: PURPOSE:To obtain hydrogen sulfide having high concentration without using a catalyst in production of hydrogen sulfide by reacting sulfur with hydrogen by blowing a hydrogen gas through a liquid phase part of sulfur heated to a specific temperature. CONSTITUTION:Liquid sulfur 2 is heated to >=250 deg.C reaction temperature by a heat exchanger 4 useful both for heating and for cooling inserted into a reactor 1. Then a hydrogen gas is blown from a nozzle 5 at the lower part of the reactor 1 through the liquid sulfur 2. The hydrogen gas is brought into contact with the liquid sulfur 2 and reacted with sulfur in a catalyst-free state to give a hydrogen sulfide gas. The temperature in the reactor 1 during the reaction is balanced by reaction heat generated by reaction between hydrogen and the liquid sulfur 2 and vaporization of the liquid sulfur 2 and maintained at an approximately constant temperature. When the reaction heat is excessive and the temperature becomes >= a prescribed temperature, the liquid sulfur is cooled by the heat exchanger 4. The reaction temperature is preferably 250-600 deg.C.

Abstract: PURPOSE:To prevent the dielectric breakdown from taking place adjacently to a ring electrode by a method wherein a high-voltage resistant transistor is provided, where an inner edge of a ring-like electrode is arranged nearer to a base electrode than an inner edge of a ring-like diffusion layer. CONSTITUTION:An inner edge 151 of a ring-electrode 15 is arranged nearer to a base electrode 14 of a high-voltage resistant resistor than an inner edge 131 of an N-type diffusion layer 13. That is, provided that distances between an outer edge 141 of the base electrode 14 and the inner edge 151 of the ring electrode 15 or the inner edge 131 of the N-type diffusion layer 13 are represented by X1 and X2 respectively, X1 and X2 are so set as to satisfy the inequality X1< X2. In the structure of the ring electrode 15 covering the N-type diffusion layer 13, the part E of a semi-insulating film 16 overlapping with the N-type diffusion layer 13 is kept everywhere at the same potential as the N-type diffusion layer 13. Therefore, even though a depletion layer 18 does not exist, an electric field is hardly applied onto a semi-insulating film 17 at the part E, so that a dielectric breakdown is prevented from taking place at the part E.

Title: Suspension for vehicle
Inventor: YOSHIMOTO YOSHIAKI
IPC: B60G15/06
Filed: 1981-12-18
Abstract: PURPOSE:To remove a fall of a coil spring resulting from a gap between two axes, by making the central axis of the coil spring identical with the shearing central axis of a rubber mount. CONSTITUTION:A coil spring 15 is provided by shifting its central axis O2 on the outside of a shock absorber 14, and the upper part of the coil spring 15 is installed on a seat 24 of a vehicle body side through a rubber mount 30. The rubber mount 30 connects a seat 24 with the coil spring 15 by three mounting pieces 30a by keeping away from a different shape part based on a seat 23. Because of this, shearing central axis O3 of the rubber mount can be made indentical with the central axis O2 of the coil spring 15. Because of this, a fall of the coil spring resulting from an inclination of the rubber mount is not generated even if a load is applied. Slide resistance of the shock absorber, therefore, is not increased and comfort in riding is not deteriorated.

Title: Optical disk processor
Inventor: INOUE RIYUUICHI
IPC: G11B20/18
Filed: 1982-11-22
Abstract: PURPOSE:To avoid deteriorating the characteristics of large capacity not by deciding all defective sectors to the faults of hardware which are temporarily generated in a writing mode but by performing the checking after writing to decide the normal sectors. CONSTITUTION:An optical disk processor 10 reads an index ID with an instruction given from an upper device 30 and positions it to a desired sector. An ECC recorder checks whether the read-out sector has a defective pattern. Then the data of fixed length and its error correction code ECC given from the device 30 are supplied to an optical disk device 40 and also written to an optical disk medium 50 with a nondefective sector. However in case a hardware error is detected by a detecting circuit 24 during the write processing of the data of fixed length and its ECC, the data of fixed length of the written data is read. If this data has no error, the data is decided correct to complete the processing. While a defective pattern 4 is written to the written sector if the read data has an error.

IPC: G01B7/00
Filed: 1991-08-15
Abstract: PURPOSE:To dispense with a mechanical element on the occasion of measurement of the operation of an electromagnetic plunger, to enable execution of measurement even in a state wherein the plunger is fitted to another device and to obtain a high precision in measurement. CONSTITUTION:An operating current is supplied to an electromagnetic plunger 1 through a shunt resistor 31. Voltages applied to terminals 4a and 4b of the plunger 1 are inputted to a band-pass filter 32, while voltages extracted out of the opposite ends of the shunt resistor 31 are inputted to a band-pass filter 33. An output voltage of the band-pass filter 32 is divided by an output voltage of the band-pass filter 33 and the quotient is detected and converted into a pulsating voltage by a detector 35. This pulsating voltage is inputted to a low- pass filter 36 so that only a low-frequency component thereof be extracted, and this is outputted to a recorder 37 as a change of a recordable DC voltage. The relationship between the position of an inner ring 2 of the plunger 1 and time can be known from a recorded waveform 39 of this recorder 37 and the operating state of the plunger can be measured therefrom.

Title: Fuel exchange gripper of fast breeder
Inventor: TOZAWA KATSUHIRO
IPC: G21C19/19
Filed: 1988-08-18
Abstract: PURPOSE:To prevent empty grasp of a fuel rod by allowing a gripper claw to be in a closed condition by touching a sensing shaft to the fuel rod, inserting the claw in the fuel rod to lower a claw closing rod and opening the claw to engaging with the fuel rod. CONSTITUTION:A lock member 16 is attached to a body shell 19 by a spring to allow a claw closing rod 6 to penetrate. Ball screws 12 is rotated and driven to lower a gripper 20, a sensing shaft 9 is pushed in when the sensing shaft 9 attached t the edge of the member 16 touches to the head part of a fuel rod 8, and the engagement of a gripper claw lock mechanism 10 and a gripper claw 7 of the member 16 is released. A spline 1 is rotated and driven to lower the rod 6, the claw 7 is moved in an opening direction to lock with a fuel rod 8. Since the shell 19 climbs as it is when the fuel rod 8 is hooked up, the member 16 is relatively lowered to the shell 19 and the claw 7 is locked by the pawl locking mechanism 10 as it is in the opening condition. Accordingly, the fuel rod 8 is hooked up without any fear in which the fuel rod falls because the claw 7 cannot be allowed to open unless the fuel rod 8 is inserted and the shaft 9 is pushed in again.
