Title: Motor speed detector
Inventor: AIDA TAKESHI
IPC: H02P29/00
Filed: 1991-05-17
Abstract: PURPOSE:To accurately detect the speed of a motor by measuring the speed of the motor up to the same resolving power as a quadruplex method and compensating the deterioration of the phase accuracy thereof. CONSTITUTION:The signals (phiA, phiB) shifted by 90 deg.C in phase obtained from an encoder and the reversal signals thereof are formed and signal cycles are measured by timer counters 142a-142d. At the predetermined taking-in sampling point of time, the measured values of cycles completed in measurement immediately before said point of time are discriminated by flip-flops 146-146d and the speed of a motor such as the rotational speed thereof is detected based on said values. The speed of the motor can be detected in the same resolving power as a quadruplex method and, since divided cycles are not measured but the whole of one cycle is measured, the effect of a factor deteriorating phase accuracy such as offset shift is eliminated and, since the speed of the motor is detected based on the measured data immediately before detection timing, the degree of detection delay is reduced.

Title: Remote operation type circuit breaker
Inventor: OISHI HIROTOSHI
IPC: H03K17/08
Filed: 1988-05-09
Abstract: PURPOSE:To decrease an operation number of times of contacts and increase their life by releasing switching elements when overcurrent is detected and releasing the contacts when a shortcircuit current is detected. CONSTITUTION:Instantaneous extension devices 16-18 are connected in serial relation with switching elements 7-9 to operate a trip mechanism 6 when abnormal current such as shortcircuit current goes through a circuit to release contacts 2-4. Longer limit time extension devices 19-21 are connected with the switching elements 7-9 in serial relation similarly to the instantaneous extension devices 16-18 for controlling a control circuit 12 when overload current goes through the circuit to produce an opening signal for the switching elements 7-9. Current breaking devices thus differ based on the size of the current. An operation number of times of the contacts is thus decreased, and the life of the contacts is increased, thereby the life of the breaker is increased.

Title: Magnetic recording medium and its production
Inventor: SAKAI YUUSAKU
IPC: G11B5/725
Filed: 1983-06-22
Abstract: PURPOSE:To obtain a magnetic recording medium which excels in the durability of the lubricant for long use and the wear resistance by having a specific form for the surface of a protecting film on a magnetic recording layer and supplying a lubricant to the magnetic layer. CONSTITUTION:A magnetic recording medium contains a protecting film 2 formed on a magnetic recording layer 1 provided on a substrate. Countless minute projections 7 having heights larger than a certain intermediate level L are formed on the surface of the film 2 together with countless minute recessed 8 lower than the level L. At the same time, a lubricant is filled into these recesses 8. These projections 7 and recesses 8 can also be stepped. It is not needed that each projection 7 and each recess 8 have a fixed height and depth respectively. To obtain such a constitution, a solution of a mixture of a solvent containing Si and a material that is easily decomposed and evaporated by heat is coated and then baked on a magnetic recording layer formed on the substrate. Thus the hardening of the mixture solution can be performed simultaneously with the decomposition and evaporation of the material that is easily decomposed and evaporated by heat.

Title: Control rod for nuclear reactor
Inventor: TSUJI MASACHIKA
IPC: G21C7/113
Filed: 1988-05-12
Abstract: PURPOSE:To prevent corrosion products from being formed between a sheath and a diluted alloy plate by preventing the diluted alloy plate and the sheath which covers it from coming into surface contact with each other, and holding the gap between the diluted alloy plate and sheath constant at the same time and allowing a reactor cooling material to flow. CONSTITUTION:The diluted alloy plate 9a of a long-lived neutron absorbing material does not come into surface contact with the internal surface of the sheath 3a between wings 4a of the control rod, and a flow passage for reactor cooling water is secured between the diluted alloy plate 9a and sheath 3a. Consequently, corrosion products are prevented from being deposited on the gap between the diluted alloy plate 9a and sheath 3a and oxygen which is decomposed with radiation never stays in the gap, thereby improving the corrosion resistance of the sheath. Further, the gap between the diluted alloy plate and sheath is held constant, so even if the corrosion products are deposited on the gap, no press spreading force resulting from wedge operation operates on the sheath and large bending stress is not generated.

IPC: G01N1/28
Filed: 1994-04-28
Abstract: PURPOSE:To easily and accurately perform visual recognition and discrimination of a cutting part tip form so as to enhance efficiency of analyzing operation and improve reliability by selectively applying a masking process to a binder (bond) holding diamond abrasive grains. CONSTITUTION:A masking layer of clear and uniform color tone which can be discriminated from diamond abrasive grains is applied to a surface part of bond. First, water washing is applied after degreasing cleaning with a volatile solvent, and then acid cleaning is applied with an aciditic aqueous solution so as to remove an oxide film on the surface. Out of electroplating, electroless plating, electrostatic coating and the like listed as a masking process method, the electroplating utilizing an electric specific resistance difference between diamond and bond is preferable. In this case, electrolytic copper plating using copper cyanide. copper sulfate or the like is preferable, and in these, copper cyanide plating can provide a clear and uniform masking and easy operability. As a result of this masking process, discrimination between the diamond abrasive grains and the bond is clarified and analysis through visual observation can be facilitated.

Abstract: PURPOSE: To hinder plural key levers from being depressed simultaneously and keep the other key levers in inmanipulable condition unitil the printing action of the depressed key lever is completed, by controlling the interposers using specified cam members.  
     CONSTITUTION: When a key lever 5 is depressed and the main rotary shaft 39 starts to rotate, the first cam surface 23a and 29a of the first and second driving members 23 and 29 engage the driven projections 17g and 25g of the first and second interposers 17 and 25, respectively, thereby preventing the other key levers 5 from being depressed. On the other hand, when the interposers 17 and 25 stopped by hooking on a hook plate 21, the immobilized engagement of each of selection levers 12, 14 is released by the second release cam 42, so that levers 12 and 14 return to their initial positions, thereby preventing the occurrence of repeated printing which might otherwise be caused by continuous depression of the same key lever 5. Although the key lever 5 operated immediately after the release action is effective, the second cam surfaces 23b, 29b of the driving members 23, 29 function to ensure that the operator can tactually sense the undepressible condition of the key lever 5.

Filed: 1993-04-19
Abstract: PURPOSE:To improve energy absorbing ability by using a compound material of resin and reinforced fiber provided with at least three layers of reinforced fiber layers, and making the thickness of an outer side reinforced fiber layer thinner than the thickness of an inner one. CONSTITUTION:The thickness of reinforced fiber layers 42a, b of a cylindrical energy absorbing member 41 which consists of a compound material of resin and reinforced fiber provided with the six layers of reinforced fiber layers, for example, is thicker than the thickness of outer reinforced fiber layers 44a, b, and the thickness of inner material reinforced fiber layers 43a, b is in the middle of them. Accordingly, a difference in the curvature radius of bent outside surface and the inner side surface of the layers 42a, b becomes large, thus increasing the tensile strength of the bent outside surface side and the compressive stress of the bent, inside surface side if the thickness of inmost layers 42a, b is set properly, outmost lavers 44a, b can be bent to be destroyed and the inmost layers 42a, b can be also destroyed. All the intermediate layers 43a, b can be destroyed at the same time in the same way. It is thus possible to use all the strength of the respective layers for energy absorption with high efficiency.
