Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To maintain higher transmissivity of light beam by preventing adverse effect by fusing deposition to assure highly accurate optical detection at the time of providing later a prism formed as the other part by arranging a light guiding portion of the prism to optically detect the end portion of a magnetic tape in such a manner that such guiding portion is not in contact with a shell body. SOLUTION: A recessed area 35 in the length almost along the length direction of prism 4, namely almost equal to a light guiding portion 4e through which the detected light beam 6 from a light emitting element 5a is provided to the area where a prism 4 of an upper shell 1 is provided. The prism 4 can be mounted to the upper shell 1 by inserting a caulking boss provided to the upper shell 1 into a hole of a flange provided in both sides of the light guiding portion 4e and this boss is caulked for mounting with an ultrasonic fusing deposition horn. Thereby, the recessed portion 35 prevents fusing deposition between the light guiding portion 43 and upper shell 1 and the detection beam 6 entering the light guiding portion 4e is never attenuated to assure highly accurate optical detection of the end portion of the magnetic tape 3.

Filed: 1988-06-06
Abstract: PURPOSE:To prevent the generation of thermal stress by forming a plenum section to the bottom of a lower dry well and interposing a water storage layer into which the pool water of a suppression chamber is introduced to the plenum section. CONSTITUTION:The part of the dry well is formed of the upper dry well 6 in the upper part of a diaphragm floor 4 and the lower dry well 7 enclosed by a reactor pedestal 2. A floor plate 8 is held exposed to the lower part of a reactor pressure vessel 3 in this case and, therefore, the floor plate 8 is heated by the temp. rise of the lower dry well 7 and the radiation heat from the bottom of the reactor pressure vessel 3, but the heat of the floor plate 8 is directly cooled by the water storage layer 10 if the water storage layer 10 of the plenum section 9 is held full of the water.

Title: Clutch control device for vehicle
Inventor: IMANI YUICHI
IPC: F16D48/02
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To enhance the durability of a device by extending the life of a pressure reducing valve to be used for gradually reducing the internal pressure of a release cylinder when a clutch is engaged therewith. SOLUTION: A pump 10 and a check valve 14 are provided for a pressure increasing system feeding working oil to a release cylinder 6 in order to release a clutch 2, and two normally closed type electromagnetic valves (a first and a second pressure reducing value) 21 and 22 for engaging and a normally opened type electromagnetic valve (a third pressure reducing valve) 23 are provided for a pressure decreasing system intermittently discharging working oil out of the release cylinder 6 in order to allow the clutch 2 be engaged therewith. When the clutch 2 is to be engaged, the hydraulic pressure of the release cylinder 6 is gradually decreased by letting the first and second pressure reducing valves 21 and 22 be alternately opened in a state that the third pressure reducing valve 23 is kept closed. As a result, the operations of the first and second pressure reducing valves can be reduced in frequency, so that its life can thereby be extended. Besides, since no electromagnetic valve for increasing pressure, is provided for the pressure increasing system, any current device can be used as is without increasing the electromagnetic valve.

IPC: H05K13/00
Filed: 1986-06-14
Abstract: PURPOSE:To eliminate a loss of time when an error detection means issues an error detection signal by constituting such that a control means causes a buffer to take in parts in an order difference from that specified. CONSTITUTION:A parts storage part 11 stores parts 1-8 while a buffer 12 takes in the parts from the parts storage part 11 one by one in the order to 1-8. An attachment means 14 takes the parts 1-8 one by one out of the buffer 12 and attaches them to specified positions on a printed circuit board 13 while a control means controls both the buffer 12 and the attachment means 14. The attachment means 14 grips a part at a specified position on the buffer 12 according to a grip instruction from the control means and attaches it according to an attachment instruction. An error detection means detects an attachment error of the parts 1-8 and issues an error signal to the control means. Then the control means causes the buffer 12 to take in the parts 1-8 in an order different from that specified.

Title: Apparatus for detecting abnormality of number-of-rotation sensor
Inventor: MEGURO KAZUHISA
IPC: G01P15/00
Filed: 1987-06-02
Abstract: PURPOSE:To accurately judge abnormality such as disconnection, by applying a predetermined signal to the signal wire of a rotation detecting means when rotational acceleration is a predetermined value or larger and a rotational speed is zero and judging abnormality. CONSTITUTION:In a rotary sensor 4, the magnetic field piercing the coil of an electromagnetic pickup changes by the movement of the projections of a hub rotor 14 to generate a sine wave like voltage wave form and the output wave of said rotation sensor 4 is inputted to a wave form shaping circuit 16 to be shaped in its wave form. Next, on the basis of the number of the pulses sent out from the circuit 16, a wheel speed V and wheel acceleration AV are calculated in a CPU 18 and it is judged whether the acceleration is a predetermined value AG or more and the speed V is zero. Subsequently, the CPU 18 generates a dummy generating signal so that a judge signal generating circuit 24 generates a square wave (dummy signal) of predetermined voltage Vcc. Further, the dummy signal outputted from the circuit 24 is converted to a digital signal by an A/D converter 28 to be inputted to the CPU 18. The CPU 18 judges the disconnection of the sensor 4 when the acceleration AV is the predetermined value AG or larger and the speed V is zero.

Title: Security system provided with entrance route regulation function
Inventor: IWAMOTO HIDEJI
IPC: G08B25/04
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent illegal invasion into a building and to regulate entrance routes to plural confidential areas in the building. SOLUTION: Collation devices R1 to R7, U7 and W7 regulating entrance by the fingerprint, the retina and the key (individual registration data) of an invader are installed at the entrances/exits of respective security areas (conference rooms, laboratories and information management rooms). A control part installed apart from the collation devices executes control. Entrance routes (entrance route regulation data) to the plural confidential areas, which are set for every individual or group, are stored in the control part. The control part unlocks the doors T1 to T7 of the respective entrances/exits when data are matched in collation based on the collation result of individual registration data by the collation devices R1 to R7, U7 and W7 and a collation result whether a person follows the route as entrance regulation data.  Thus, even a person permitted to invade into the building cannot freely enter/leave the plural security areas and entrance regulation management in each of security areas in the building becomes more strict.

Title: Method and device for controlling projection of molded form of injection molding machine
Inventor: OKAMOTO RIICHI
IPC: B29C45/82
Filed: 1988-06-06
Abstract: PURPOSE:To conduct full automatic operation without damaging the quality of a molded form, and to shorten the molding cycle time by making the speed of projection larger than first speed at a front position, where a projection forward completion position is projected at a value larger than first forward completion position, in second and subsequent projection. CONSTITUTION:An ejector pin 11 is projected plural times during a unit cycle, and a molded form 10 is mold-released and projected. The ejector pin 11 is projected while release forward speed is made slow in an extent that the molded form is not deformed and damaged during a time from the release start position 9a of the molded form 10 to a first forward completion position on first projection. A projection forward completion position is brought to a front position projected at a value larger than the first forward completion position and the speed of projection is made larger than first speed in second and subsequent projection. Accordingly, all precision molded forms can be lowered positively in the manufacture of a large number of the precision molded forms laying stress on dimensional speed, strain, etc., and a high cycle can be brought without using an automatic extractor.
