Title: Plunger pump and multiple-connected plunger pump device
Inventor: TOJO NOBUO
IPC: F04B1/16
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To restrain residue of air in a ring seal space by communicating at least two pieces of communicating passages reciprocally extending in parallel in the axial direction of a plunger to the space between ring seals through which the plunger formed between the high pressure side seal and the low pressure side seal passes at a position separated from it in the peripheral direction. SOLUTION: Each of intake port side ring spaces 80 is communicated to a space 62 between ring seals through three pieces of grooves 78, and liquid in an intake port 74 flows in the space 62 between the ring seals through the grooves 78. As the three grooves 78 are arranged with equal intervals in the peripheral direction of the space 62 between the ring seals, even when a horizontally set triple plunger pump device 10 is set at an optional peripheral directional position around a central line of a pump input shaft 22, one of the three is positioned at an upper half part of the space 62 between the ring seals and the remaining one is positioned at a lower half part of the space 62 between the ring seals.  Consequently, at the time when liquid flows in the space 62 between the ring seals, liquid flows in the inside of the space 62 between the ring seals from the groove 78 of the lower half part, and air in the inside of the space 62 between the ring seals is extracted from the groove 78 of the upper half part.

Inventor: OGURA SHIRO
IPC: H03K19/20
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To enhance the throughput by suppressing an increase in the number of bus signal lines and actualizing a multiple communication. SOLUTION: Unique bus levels are assigned for every binary logic signal outputted by functions 4a, 4b, and 4c. A driver 6 when receiving the binary logic signals 64, 62, and 61 through a bus level selecting circuit 5 converts the binary logic signals into analog signals of voltages having an amplitude e.2n-1, where (n) is the bus level of the binary logic signal and (e) is a reference voltage. When plural binary logic signals are inputted at the same time, the driver 6 generates a multi-valued logic signal by superposing the analog signals converted into the bus levels of the binary logic signals to actualize a multiple communication. A receiver 7 operates reversely to the driver 6 to encode the multi-valued logic signal received through the bus 1 into binary logic signals 74, 72, and 71 and send them out to the respective functions 4a, 4b, and 4c.

Abstract: PROBLEM TO BE SOLVED: To improve the function of a buffer type guard fence by arranging a support section and a buffer body between interfaces of an upper skeleton and a lower skeleton, and setting the fence on a road surface so that its side walls extend along a vehicle traveling direction. SOLUTION: A buffer type guard fence 1 is constituted of an upper skeleton 2 and a lower skeleton 3 each formed of a rigid body, and a cushioning material 4 interposed between them. Side surfaces of each skeleton 2, 3 are disposed so as to form vehicle-facing wall surfaces 17. Next, an interface 2a at the bottom of the skeleton 2 is formed into a convex curved surface, and a convex portion 3c having an almost trapezoid cross section is protrusively formed at an almost central portion of an interface 3a on the upper surface of the skeleton 3, so as to abut on the interface 2a. Then, the cushioning material 4 has its upper surface slant along the curved surface of the interface 2a to be progressively spread toward edges 4c, and the cushioning material 4 is rigidly fixed to the interfaces 2a, 3a. When the fence 1 is laid, an anchor bolt 10 erected on foundation concrete is inserted into anchor bolt embedding hole 9 of the skeleton 3, to thereby fix the fence 1. Thus, fatigue of the buffer material can be prevented, and an impact force generated at the time of vehicle collision can be drastically alleviated. Further, after receding of the impact force, the guard fence can be erected to assume its original position.

Title: Corrosion resisting high tensile steel wire and corrosion resisting coil spring using same
Inventor: YAMAMOTO SUSUMU
IPC: C25D7/06
Filed: 1989-08-23
Abstract: PURPOSE:To obtain a plated high tensile steel wire for coil spring excellent in corrosion resistance by plating the surface of a high tensile steel wire with Cu alloy and further forming a plating layer of Ni or Ni alloy on the above. CONSTITUTION:In order to make a coil spring of a high tensile steel wire and improve the corrosion resistance of the spring, a plating layer 2 of Cu alloy, such as Cu-Zn alloy and Cu-Sn alloy, is formed on the surface of a steel wire 1 as a stock to 0.04-1.5mu thickness. Successively, a plating layer 3 of Ni or Ni alloy is formed on the above. Even if a pinhole (a) and a pinhole (b) are formed in the Cu alloy plating layer 2 and the Ni or Ni alloy plating layer 3, respectively, the Ni plating layer 3 is not subjected to cathodic protection because it is kept in noncontact with the steel wire 1 as a substrate, though it has a cathodic protection effect to the Cu alloy plating layer 2. As a result, the corrosion resistance of the steel wire can be remarkably improved synthetically by means of double layer coating, and this steel wire can be used in the form of a plated steel wire of >150kgf/mm<2> tensile strength as a superior stock for spring coil composed of corrosion resisting high tensile steel wire.

Filed: 1983-11-18
Abstract: PURPOSE:To improve the control reliability of a control system wherein temperature sensor is used by comparing a temperature detected by the temperature sensor, with an engine temperature calculated on the basis of an air fuel ratio feedback period and compensating a sensor output according to the compared result. CONSTITUTION:When air fuel mixture ratio is changed from lean mixture to rich mixture. The temperature of an engine is calculated from a feedback period and the compensated value of the output of a temperature sensor 9 is also calculated according to the said engine temperature. The feedback compensating coefficient of the quantity of fuel injected is thereafter compensated. Namely, the output inversion time (t2) of an O2 sensor is read from a timer 1 as well as the time (t1) at which the precedent output of the O2 sensor is inverted from a lean-mixture ratio to a rich-mixture ratio. From both the times (t1) and (t2), the feedback period TF/Bis computed to update (t1) to (t2). At the next step, from a memory, a reference feedback period TF/Bref corresponding to the water temperature TW' is read and compared with an actual feedback period. In case of TF/Bref, the water temperature compensation value Twofs is corrected by DELTATwofs to a lower value and in the contrary case, the water temperature compensation value is corrected to a higher value.
