Title: Antilock brake control device
Inventor: HIGASHIMATA AKIRA
IPC: B60T8/58
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To exploit an excellent anticlock brake control performance by preventing an over pressure reduction from occurring at the time of antilock brake control so as to suppress a variation in vehicle deceleration. SOLUTION: When a target increasing or decreasing pressure amount ΔPi based a wheel speed and wheel acceleration becomes negative which indicates pressure reduction, a pressure increasing or decreasing time Tp is set according to the target increasing or decreasing pressure amount ΔPi, a pressure increasing or decreasing interval (m) is set at a specified value m0, and an operating mode is set at a pressure reducing mode until a set pressure increasing or decreasing time Tp during which the pressure increasing or decreasing interval (m) is passed becomes '0'. If the target increasing or decreasing pressure amount ΔPi becomes zero or positive in that mode, the pressure decreasing mode is stopped because a wheel slip is in the direction of convergence.  On the other hand, when a pressure decreasing is performed continuously even if the target increasing or decreasing pressure amount ΔPi is negative, the pressure decreasing mode is stopped because the wheel slip is in the direction of convergence when the trend of reduction of a wheel acceleration Vw1' is stopped so as to prevent over pressure reduction.

Title: Counter of very small protrusion
Inventor: KASHIWABARA TARO
IPC: G06M9/00
Filed: 1989-06-23
Abstract: PURPOSE:To remove erroneous counts caused by the resonance by so arranging as not to accept a new input pulse for a predetermined time after a pulse is input. CONSTITUTION:A signal detected via an acceleration sensor 3 of a probe 2 of a detecting part 1 is compared by a comparator 4. When the signal exceeds a set level, a pulse is output. When the pulse is input to a latch 5, the value of a counter 6 is increased. At the same time, the pulse from the comparator 4 is, through a reset circuit 7, input to a delay circuit 8 and to a reset terminal of the latch circuit 5. Since the latch circuit 5 generates no output even when a fresh pulse is input thereto until it is reset, the noises resulting from the resonance of the acceleration sensor 3 are removed.

Title: Forming method of gold layer
Inventor: NISHIYAMA MASAO
IPC: C23C18/52
Filed: 1978-12-28
Abstract: PURPOSE:To make the gold layer formed superior in corrosion resistance by forming a primary gold layer on the object article, firmly bonding the same through heating by way of a sinter layer then applying a secondary gold layer. CONSTITUTION:A primary gold plating layer 10 of thicknesses 0.5-1.5mu is formed to the surface of the object article composed of a metal outer ring 1 and lead wires 6, 7, 8. Thence, it is heated for 3-10min. at 300-450 deg.C in a neutral atmosphere and this causes part of the primary gold plating layer to enter the crystal grains of the metal outer ring 1 and lead wires 6, 7, 8, thereby forming a sinter layer 11 and resulting in increased adhesion force and disappearance of pinholes, etc. Thence, a secondary gold plating layer 12 of thicknesses 1-5mu is formed on the primary gold layer 10 to make the total tickness of the plating layer specified 1.27-5.08mu. By this method, the gold layer of superior corrosion resistance is formed.

Title: Planar fluorescent lamp
Inventor: HONDA HISASHI
IPC: H01J61/30
Filed: 1988-06-30
Abstract: PURPOSE:To realize a thin form and a light weight and to expand the effective luminous area by inclining the inner surface of a spacer in a specific angle to oppose to the inner surface of a front plate. CONSTITUTION:Spacer elements 23a are composed to make the width of the lower side contacting to the outer edge of a rear side plate 22 larger than the width of the upper side contacting to the outer edge of a front side plate 21. Since the width of one end of a spacer 23 contacting to the rear side plate 22 is expanded by the inclined surface of the inner surface of the spacer 23 in such a way, the contact area of the spacer 23 and the rear side plate 22 is expanded, and the stress to the outer air pressure of the rear side plate 22 is reduced. Consequently, the thickness of the rear side plate can be made smaller than that of the front side plate, a thin form and the light weight of the whole unit are realized, and the effective luminous area is expanded.

Title: Syringe pump and injecting method
Inventor: TACHIBANA YASUHARU
IPC: A61M5/00
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To make an alarm come out before injection finish regardless of syringe type and injection pattern by operating the plunger position before medicine liquid injection finish by an inputted set injection pattern and generating an alarm when the plunger reaches the position. SOLUTION: When the power source is switched on, and priming such as maker's name input and syringe diameter detection is finished, setting of the injection pattern is made by an injection pattern setting input means 60. Based on this setting, CPU 90 operates the preliminary notice alarm position by a preliminary notice position operating means 30B. At this time medicine injection is started by pushing a starting switch. A plunger position detecting means 30A detects the plunger position as injection progresses, and compares the preliminary notice position by a comparing means 20. When the plunger is judged to have reached the preliminary notice alarm position, an alarm is generated by an action indicator. Thus, an alarm can be generated before the predetermined injection finishing time regardless of syringe type and injection pattern.

Abstract: PURPOSE:To forcibly precipitate carbides at grain boundaries and to improve resistance to a grain boundary damage by heating the internally damaged part of a heat transmission pipe made of a high-Ni austenitic alloy to a specific temp. for the specific time by a gas burner. CONSTITUTION:A flexible tube 14 of a local heat treatment device 12 is inserted into the heat transmission pipe consisting of the high-Ni austenitic alloy, more particularly the heat transmission pipe 10 which is a steam generating tube of a pressurized water reactor by the operation using a robot. The positioning of the front end of the tube 14, and the supply and ignition of a combustion gas and O2 are executed by a remote control. The front end of the tube 14, i.e., the burner part 16 advances into the pipe. The insertion is temporarily stopped when said part arrives at the point of a pipe supporting plate 11. The supply of the combustion gas and O2 is then started to ignite the gas and O2. The combustion is controlled while the temp. measured by a thermocouple 18 is monitored. The internally damaged part of the pipe 10 is thus heated for 1-50min at 600-750 deg.C.

Filed: 1982-09-20
Abstract: PURPOSE:To form the time width of two levels exactly and stably by setting the time width of one of the two levels that constitute a binary signal and setting another time width independently of one time width. CONSTITUTION:An IC20 for an oscillator receives signals from a three-contact key 21 through a group of resistance 22, 23. When one of dial keys 21 is depressed, a capacitor C21 is charged and if a terminal voltage exceeds 2/3 Vcc, the seventh pin of the IC20 becomes a discharge terminal and becomes GN level. The charge of the capacitor C21 is discharged through resistance RB21-RB24 and a key contact, and a point C becomes the same potential with the seventh pin. A transistor (Tr) 2 turns off and Tr1 also turns off. When the terminal voltage of the capacitor C21 attains 1/3 Vcc, the output B of the IC20 is inverted, and the capacitor C21 starts charging. By this way, the dial signals of a binary coding can be formed exactly and stably.
