Title: Hip sintering method
Inventor: SHIMIZU TSUTOMU
IPC: B22F3/15
Filed: 1994-07-15
Abstract: PURPOSE:To efficiently produce a sintered compact product of discoid having a flat top and a flat bottom by filling a capsule can, formed so that respective wall thicknesses of a top and a bottom are larger than the wall thickness of a cylindrical part, with an alloy powder, deaerating the inside and hermetically sealing the capsule can, and then applying HIP treatment. CONSTITUTION:A cylindrical capsule can 1, consisting of a top 12, a bottom 10, and a cylindrical part 11, is filled with a raw material powder 2 consisting of an alloy with a prescribed composition. This capsule can 1 is deaerated and hermetically sealed and then subjected to HIP treatment. The resultant sintered compact is machined, thereby, a product of sintered compact having a discoid shape in which a length in a diameter direction is greater than a length in an axial direction is obtained. In this HIP sintering method, respective wall thicknesses of the top 12 and the bottom 10 of the capsule can 1 are regulated to values greater than the wall thickness of the cylindrical part 11 and also 0.5 to 2 times the filling thickness of the powder 2. By this method, HIP can be applied to the capsule can while practically preventing the occurrence of hollows in the top and the bottom surface of this capsule can, and the shortening of machining time and the improvement of material yield can be attained.

Title: Charge detector
Inventor: KIMURA TETSUJI
IPC: H04N5/335
Filed: 1993-07-02
Abstract: PURPOSE:To reduce reset noise by setting the depleting potential in the region under the gate electrode of a reset transistor higher than the channel potential when the reset transistor turns ON, and setting the depleting potential in the region except the above region lower than the channel potential. CONSTITUTION:A reset transistor(RTr) is constituted of a gate electrode 7, a drain electrode 8, etc., P-type impurity ions are implanted in the region shown by dotted slant lines, except a rectangular region from a contact part 6 to a gate electrode 7. When the RTr turns ON, the reset drain voltage VRD in the region shown by the dotted slant lines becomes lower than the channel potential and higher than the depleting potential of a floating diode(FD) 3, which is completely turned into a depletion state. Thereby the reset noise can be reduced. The rectangular region from the contact part 6 to the gate electrode 7 is not turned into a depletion state when the RTr turns ON, so that generation of imperfect reset can be prevented.

Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To secure a high contrast of the recording information and to improve the visibility for a noncontact type IC card by forming a transparent/opaque type reversible thermal recording layer having an insulating metal luster reflecting layer on one of both sides of the IC card. SOLUTION: A rewrite area A1 and a print area A2 are formed on the surface of a contactless IC card A. The area A1 is rewritable, and an issuing company name, a pattern, etc., are shown in the area A2. Furthermore, a transparent/opaque type reversible thermal recording part is added to the area A1. A long-chain low molecular material consisting primarily of organic acid is scattered into the high molecular resin at the thermal recording part. Thus a thermal recording layer 5 is formed to reversibly show a transparent/opaque state that is caused by the heat generated by a heat source such as a thermal head, a heating plate and a laser beam.

Title: Hydraulic drive type water injector
Inventor: HARA JUNICHI
IPC: F02B3/06
Filed: 1992-05-29
Abstract: PURPOSE:To enable a constant amount of water to be discharged for a long period of time by a hydraulic drive type water injector applied to a water distributer of a diesel engine using a water injection fuel valve in which a discharge spool is driven by oil pressure so that water in a water chamber is pressurized to be discharged. CONSTITUTION:While a discharge spool 1 is inserted in a cylinder 3, a spool stopper 4 is fixed movably axially of the cylinder 3 to determine the stroke volume of the discharge spool 1.

Title: Anti-dive device for vehicle
Inventor: ITOU HEIICHI
IPC: B62K25/08
Filed: 1982-09-22
Abstract: PURPOSE:To prevent a car frontage from nose-diving in time of just braking, by making up a pressure regulating chamber inside a shock absorber by way of partitionment, while boosting the pressure inside the pressure regulating chamber in time of braking, in case of a vehicle holding a front wheel elastically by means of a telescopic type air- sealed shock absorber. CONSTITUTION:In time of non-braking, since the inside of a pressure regulating chamber 60 comes into a state of atmospheric pressure, a rubber bag 54 serving as a movable wall making up the pressure regulating chamber 60 is crushed by internal pressure of an air chamber 52 and therefore the volume of the air chamber 52 increases. And, when a front wheel runs on to the convex part of a road surface, oil in an oil chamber 30 flows into an oil chamber 32 whereby a shock absorber 10 is compressed to some extent. At this time, an inner tube 14 enters the inside of an outer tube 12, causing the air chamber 52 to act as an air spring. On the other hand, in time of braking, an electromagnet of a selector valve 78 in a pressure governor unit 64 is excited, leading the air pressure of a tank 74 into the pressure regulating chamber 60. As a result, the rubber bag 54 is inflated large, pressurizing the air chamber 52, and thereby all springs of the shock absorber 10 are made to stiffen on the whole. Therefore, a nose dive at the car frontage can be prevented.

Title: Time synchronization system
Inventor: IMAOKA ATSUSHI
IPC: H04L12/00
Filed: 1990-06-22
Abstract: PURPOSE:To allow the system to synchronize a time of a slave set with a time of a master set accurately even in the case of changeover of transmission lines by correcting a delay time of a transmission line interconnecting the master set and the slave set so as to synchronize the time of the slave set with the time of the master set. CONSTITUTION:A reference time signal 6 from a reference time generating section 3 of a master set 1 is sent to a slave set 2. The slave set 2 returns the received signal 6 to the master set 1. A time interval measuring device 5 of the master set 1 measures a time difference between the sent signal 6 and the returned signal 6 and sends a half of the difference to the slave set 2 as time information A. A time interval measuring device 14 of the slave set 1 measures a time difference between the signal 6 from the master set 1 and a reference time signal 17 outputted from a reference oscillator 13 in the slave set 2 and uses the result as time information B. A time information arithmetic section 15 obtains a difference between the time information sets A and B and sends the result as time information C to a time information correction section 16. The correction section 16 subtracts a correction value from the information C as control information 21 and sends it to a phase control section 12. The control section 12 applies phase control of the signal 17 based on the information 21 to generate a synchronizing time signal 28 synchronously with the time of the master set 1.
