Title: Tyre for heavy vehicle
Inventor: TAKEUCHI AKIHIRO
IPC: B60C11/11
Filed: 1984-09-03
Abstract: PURPOSE:To reduce heel and toe wear in proportion to the amount of wear and prolong the life of a tyre by providing a side wall which is varied to have a greater angle with respect to the turning axis of the tyre when a lateral groove proceeds to wear. CONSTITUTION:In a cross-sectional view A-A' relating to a central lateral groove close to the equator of a tyre, an inclination angle beta2 with respect to the reference line L perpendicular to the tread face of the side wall at the step-in side E2 is less than an inclination angle beta1 with respect to the reference line L of the side wall at the step-out side E1. In another cross-sectional view B-B' of a central lateral groove RG1, that is taken from the view point of the tread end, an inclination angle gamma2 of the side wall at the step-in side E2 is made greater than an inclination angle gamma1 of the side wall at the step-out side E1. An angle alpha of the central lateral groove RG1 with respect the turning axis of the tyre will therefore be varied to a greater value in proportion to the amount of wear on a tread part, whereby prolonging the life of the tyre.

Title: Front end
Inventor: YAMAUCHI YOSHIMASA
IPC: H04B15/06
Filed: 1986-08-06
Abstract: PURPOSE:To improve reception performance by including a frequency divider to frequency-divide a local oscillating signal from a local oscillator circuit in a casing, and outputting a divided signal from the frequency divider outside the casing. CONSTITUTION:Since a local oscillating signal from the local oscillator circuit 6 is frequency-divided by the frequency divider 12 and made a low frequency signal and outputted to a frequency-divided signal output terminal 14, the unnecessary radiation from a cable leading to the terminal 14 comes small. The local oscillating signal is radiated only in a small quantity from the wiring that connect the local oscillator circuit 6, a mixing circuit 5, and the frequency divider 12, etc. Accordingly, such a local oscillating signal as superposed on an antena input signal from an antena input terminal 9 can be made extremely small. Since the frequency-divided signal is in a low frequency, the loss due to the inductive impedances of the cable from the divider 12 to the terminal 14 and that from the terminal 14 to a programmable frequency divider 13, is in little amount. As a result, a buffer circuit conventionally used for amplification, is not necessary.

Title: Electrostatic attraction plate utilizing remaining attraction force
Inventor: KASAHARA KEIJI
IPC: H05K9/00
Filed: 1988-07-25
Abstract: PURPOSE:To attract a matter to be attracted, and to move the whole for use by attracting the matter by utilizing predetermined remaining attraction force of an attraction layer even if power supply to electrodes is stopped. CONSTITUTION:Since an attraction layer 16 is induced by a set of electrodes 10, 12 when a DC power is supplied to the electrodes 10, 12 to apply positive and negative charges to an electrostatic attraction plate 4, a matter 14 to be attracted is generated with charge of different polarity to that of the electrodes 10, 12 by electrostatic induction at positions opposite to the electrodes 10, 12. Accordingly, an electrostatic attraction force is operated between the charge generated on the matter 14 and the charge of the electrodes 10, 12, thereby attractively holding the matter 14 on the surface of the layer. When charge is once applied to the layer 16 to generate an electrostatic attraction force, even if a power source is interrupted, predetermined remaining attraction force is maintained at the layer 16. Thus, the matter 14 can be attracted by utilizing the remaining force to move the whole to be used as a cordless electrostatic attraction plate.

Abstract: PURPOSE: To provide superior corrosion resistance to nodular corrosion to a Zr alloy by adding a specified element stabilizing β phase to the alloy.  
     CONSTITUTION: A Zr alloy having small cross-sectional area of thermal neutron absorption is used as a structural material for the core of a nuclear reactor, yet white spotlike corrosion called nodular corrosion is produced on the alloy surface by a change with the passage of time. In order to prevent the corrosion, to Zr is added at least one of 0.2W21% Mo, 0.1W6.4% Mn, 0.1W17.5% Nb, 0.1W 26% Al and 0.1W6.4% Ag, and they are alloyed. The resulting Zr alloy is quenched from the high temp. β region to form a martensite structure, and it is annealed. A black oxide film is then formed on the alloy surface by autoclave treatment or other method. Thus, the corrosion resistance to nodular corrosion is enhanced.

Filed: 1992-07-13
Abstract: PURPOSE:To make recording/reproducing possible on the same head by detecting a rear head condition, synchronizing it with a tape travelling control signal by a value calculated by a capstan phase error and a rotary signal, changing a tape travelling speed and making a time when a phase error signal becomes optimal the shortest. CONSTITUTION:The following series of procesings are carried out by a servo system 15. That is, whether a magnetic head is a rear head or not is identified by signals from a head switching signal detecting device 13 and a tape travelling control (CTL) signal head 9. When it is the rear head, based on wheter it is positive or negative against a capstan (CP) phase error value, values gained by multiplying a coeffient in the CP phase error value with the number of CP control (CPFG) signals between 1 CTL signals are deducted or added and inputted to a CPFG counter 21. They are synchronized with the CTL signal by the arithmetic processing of this counter 21 and the tape travelling speed is changed. Thus, after the correction of the tape travelling speed is finished, the time when the CP phase error signal becomes optimal is made the shortest and the recording/reproducing are done on the same magnetic head.

Filed: 1989-07-18
Abstract: PURPOSE:To enhance the efficiency of the above air conditioner and also increase its reliability by providing a pressure introducing passage that connects a vane back pressure chamber to the intermediate part of a decompression device. CONSTITUTION:Space at the rear parts of vanes 32, 33 communicate to each other through a port 36 of a partition plate 27 to form an enclosed back pressure chamber 37. Since intermediate pressure is introduced into the vane back pressure chamber 37 from the intermediate point of a capillary tube 18 through an introducing passage 38, the pressure in the vane back pressure chamber 37 shows the intermediate pressure. Accordingly, urging force that presses the vanes 32, 33 against pistons 30, 31 becomes small, and frictional force at the tip ends of the vanes 32, 33 against the pistons 30, 31 is reduced. Further, loss of a power at the tip ends of the vans is reduced. Since the rotational speed of the piston 30, 31 becomes faster, the leakage of lubricating oil from the inner diameter side of the pistons 30, 31 to the outer diameter side thereof is reduced, whereby the volumetric efficiency of a compressor is enhanced and freezing ability is increased.
