Title: Metal vapor discharge lamp
Inventor: SUZUKI TAKESHI
IPC: H01J61/38
Filed: 1978-09-27
Abstract: PURPOSE: To increase the effective illumination length on a printed matter or the like relative to the light emitting length of the lamp and to increase the left thereof, by causing the ultraviolet-ray transmittivity at the both end portions of the light emitting tube to be larger than at the center portion thereof.  
     CONSTITUTION: Enclosed in a light emitting tube 10 are mercury as a light emitting metal and argon as a rare gas. Electrodes 11, 11 are provided in the tube 10 at the both ends thereof. The light emitting tube 10 has its central portion 10a formed of normal quartz glass tube while both end portions 10b, 10b formed of synthesized quartz glass tube so that said end portions have higher ultraviolet-ray transmittivity than the central portion 10a. Accordingly, if the ultraviolet-ray intensity is  lowered at the end portions of the lamp mainly due to blackening, the ultraviolet- ray intensity at the both end portions 10b, 10 will not extremely be lowered in comparison with the centeal portion. Thus, during the usage of the lamp, shortage in  drying at the both end portions of the printed matter can be avoided.

Title: High resolution time difference measuring instrument
Inventor: KAYAMA YASUNAGA
IPC: G04F10/04
Filed: 1990-05-09
Abstract: PURPOSE:To measure the minute time by a single measurement by oscillating a second clock pulse which is adjacent to a frequency of a reference clock pulse and synchronized with a pulse to be measured. CONSTITUTION:A start pulse generator 2 receives a measurement start signal, outputs a start pulse synchronized with a reference clock pulse to a counter 3 and an optical pulse generator 4, and emits an optical pulse to a point to be measured. Subsequently, an O-E transducer 5 inputs its reflected light and outputs a stop pulse for the measurement end to a second clock pulse oscillator 6 and a counter 3, the counter 3 counts and processes a reference clock pulse between the start pulse and the stop pulse, and the oscillator 6 outputs a second clock pulse whose frequency is different from that of the reference clock pulse by allowing it to synchronize with the stop pulse. Subsequently, a second counter 7 counts and processes the clock pulse until the reference clock pulse and a second clock pulse coincide with each other, and a data processor 10 can calculate a time difference of the start pulse and the stop pulse, based on counting/ processing data of the counters 3, 7.

Abstract: PURPOSE:To prevent the infiltration of a depletion layer extending along the surface from a collector and a channel, and to improve the reliability of dielectric resistance by forming a P<+> layer into a clearance between a collector junction and an emitter junction while being stacked onto a P base electrode and an N emitter electrode. CONSTITUTION:A Si substrate 3 is used as the N collector, and a P base 4 with approximately 20mum depth, an N emitter 5 with approximately 12mum depth and a P<+> connecting layer 7 with approximately 4mum depth are formed. The emitter electrode 10 is projected to the collector 3 while crossing the collector junction 1 by 30mum and operated as a filed plate, and an electrode 9 is shaped similarly. The 15mum wide clearance 11 is formed between the electrodes 10, 9, and the N emitter junction 2 crosses the electrode 10 and is positioned in the clearance 11, and is 2mum wide and 70mum long. According to this constitution, a course to the emitter junction from the collector junction 1 crosses only a section under the emitter electrode 10 or the P<+> connecting layer 7 in the surface  because the N emitter electrode 10 overlaps onto both ends of the P<+> connecting layer 7 in the clearance 11. Consequently, the reliability of the dielectric resistance of a lateral transistor can be improved.

Title: Vibration isolating device
Inventor: TAKAGI SEIZO
IPC: F16F15/03
Filed: 1989-05-12
Abstract: PURPOSE:To rapidly attenuate a displacement due to vibration so as to enhance the reliability of a vibration isolating device in which a flexible resilient joint is disposed between a pair of attaching plates, by disposing permanent magnets between both attaching plates with their same magnetic poles being opposed to each other. CONSTITUTION:A flexible joint 2 formed of rubber or a resilient material in a bellows shape is disposed between a pair of upper and lower attaching plates 1a, 1b which are respectively attached thereto with permanent magnets 4a, 4b by means of a coupling means such as a bond or the like with their same poles being opposed to each other. If the attaching plate 1a displaces relative to the attaching plate 1b so as to decrease the distance between the permanent magnets 4a, 4b, a repulsive force by the same poles of both magnets increases with an inverse proportion to the square of the distance therebetween, that is, the magnetic repulsive force in a direction reverse to the direction of the replacement increases so that the vibration is rapidly damped. Accordingly, in case of using the vibration isolating device in an OA equipment, a measuring equipment or other equipment requiring isolating of vibration, it is possible to obtain a vibration isolating effect which is safe and highly reliable.

Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To improve performance by avoiding unconditional processor serialization after the execution of an SPKA instruction by providing processor serializing control logic, which can execute a specific instructions without serializing processors in almost all cases. SOLUTION: This processor serialization control logic includes an extraction detecting logic mechanism which detects an fetching protection bit in a stored key being turned on as to an arbitrary instruction which was fetched recently, a SPKA execution detecting logic mechanism which detects a SPKA instruction having been executed recently, and a PSW executing device serializing control logic mechanism which serializes processors only, when both these events take place. A PSW executing device 13 receives data to be loaded to PSW from a fixed-point executing device 7. Once detecting the need to serialize the processors since the SPKA instruction was executed recently, the PSW executing device 13 notifies a report to end/interrupt logic 11, which actually starts the serializing process.
