Title: Cutting tool holding device
Inventor: MIYAUCHI MIKIYOSHI
IPC: B23Q3/12
Filed: 1989-12-18
Abstract: PURPOSE:To prevent fretting corrosion of fitting surface by forming a coated layer of matrix metal made up of hard particles and a specified alloy on either of the tapered outer peripheral surface of a tool holder and the tapered inner peripheral surface of a main spindle. CONSTITUTION:A coated layer 30 of matrix metal made up of hardened particles containing 50-95% of one of carbide, boride, or nitride and one of iron base alloy, nickel base alloy, cobalt base alloy, is formed on either of the tapered outer peripheral surface of a tool holder 10 and the tapered inner peripheral surface of a main spindle 2. By this constitution, the coated layer is not only easier to handle compared to the liquid lubricant-coated layer on the tapered surface, but it will also not fracture easily due to its solid coating, and metal-to-metal contact between the base metals of the tool holder 10 and the main spindle 2 is prevented to prevent rusting and wear. The phenomenon of fretting corrosion on the tapered fitting surface can thus be prevented.

Title: Signal processor
Inventor: OZAWA KENJI
IPC: H04N17/00
Filed: 1990-11-27
Abstract: PURPOSE:To make the circuit for the processor stable without giving effect on a video signal itself by superimposing a test signal on the video signal for a blanking period of the video signal and detecting the test signal and comparing it with a reference signal thereby controlling a gain of the video signal. CONSTITUTION:An output of a superimposing section 2 is inputted to an amplifier section 3, in which the gain is adjusted to a prescribed gain and the result drives a cathode electrode of a CRT 4. Moreover, an output signal of the amplifier section 3 is an input to a feedback clamp section 5 and a detection section 6, and the clamp section 5 applies DC component recovery of the video signal. On the other hand, the detection section 6 extracts only a test signal superimposed on the video signal for its blanking period from the inputted video signal and outputs it to a control signal generating section 7 and the test signal outputted from the detection section 6 is compared with a reference signal waveform in existence in a control signal generating section 7 and a control signal to control the gain of the amplifier section 3 is outputted. The gain of the amplifier section 3 is controlled by the output signal from the control signal generating section 7. Thus, the signal processing system is made stable.

Title: Current limiting method and current limiter
Inventor: SATO TAKASHI
IPC: H02H9/02
Filed: 1990-11-30
Abstract: PURPOSE:To set impedance in every commutating circuit when an overcurrent flows in the main circuit by shifting the superconductive element within the main circuit to normal-conductive to limit the overcurrent, and then, commutating the current into commutating circuits in a plurality of stages so as to limit the overcurrent gradually. CONSTITUTION:When the overcurrent equivalent to the critical current of a superconductive current limiting element 3a flows in this current path, the superconductive condition of the superconductive current limiting element 3a collapses, and it shifts to normal-conductive condition. As a result, the overcurrent flowing in the current path is limited, and in addition the resistance of the superconductive current limiting element 3a becomes enough larger than the resistance of the resistor 7a. Therefore, the current is commutated to the commutating circuit consisting of the resistor 7a and the superconductive current limiting element 3b, and the current is limited by the resistor 7a.

Title: Damping force regulating type hydraulic shock absorber
Inventor: NEZU TAKASHI
IPC: F16F9/44
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To obtain proper damping force over the whole range from a low speed range to a high speed range of piston speed, in a damping force regulating type hydraulic shock absorber. SOLUTION: Damping force is generated by controlling fluid motion of oil liquid generated in an oil passage 44 by sliding of a piston in a cylinder. Before a main valve 33 is opened, damping force of an orifice characteristic is generated by a conduit area between ports 40, 41 of a fixing orifice 51 and a spool valve 34, and damping force of a valve characteristic is generated according its opening after the main valve 33 is opened. The orifice characteristic is directly regulated by the conduit area between the ports 40, 41, pressure in a pilot chamber 36 is simultaneously changed, and valve opening pressure of the main valve 33 is regulated. Pressure in the pilot chamber 33 is regulated by a variable relief valve 35 so as to suppress raise of the damping force.  When the main valve 33 is opened, initial deflection amounts of a large diameter ring member 47 and a relief disk 49 are reduced, the relief pressure is regulated, and thereby, raising of the damping force in a piston high speed range is suppressed.
