Title: Lead frame
Inventor: OSAKA SHUICHI
IPC: H01L23/50
Filed: 1987-02-06
Abstract: PURPOSE:To complete the plating of the wire bonding surface of a metal piece by one-time treatment, by forming a copper foil layer on the wire bonding surface of the metal piece, whose raw material is a copper based alloy material, so that 99% purity is provided and the thickness of 500Angstrom  or more is set for the copper foil layer. CONSTITUTION:A plated foil layer 11 comprising copper is formed on a wire bonding surface 5a of an inner lead 5 by using a copper sulfate based plating bath. The plated foil layer 11 has 99% purity, and its thickness is set at 500Angstrom  or more. Therefore, only the plated foil layer 11 comprising the copper is formed on the inner lead 5. Namely the plating is performed only once. Thus the plating at the inner lead 5 of the metal piece 1 can be performed by one time treatment.

Title: Light pulse generating device
Inventor: YAMADA MITSUSHI
IPC: G02F1/025
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To provide a light pulse generating device which can easily generate a light short pulse and a light pulse with a sharp waveform electrically under nonstrict conditions. SOLUTION: This light pulse generating device 100 is equipped with an optical modulator 102 applied with an electric signal varying in specific cycles. In this light pulse generating device 100, an optical path 106 which is formed on the side of a 2nd input/output part 10b of the optical modulator 102 and returned on a reflecting surface 104 is so set that light requires a time as long as a natural number multiple of a cycle of the electric signal to travel forward and backward along the optical path 106. Input light P1 inputted from a 1st input/output part of the optical modulator 102 travels forward and backward in the light pulse generating device 100.  Consequently, the light pulse generating device 100 can put intensity modulation on the going way and intensity modulation on the return way one over the other according to the cycles of the electric signal, so the light short pulse and the light pulse with the sharp waveform can easily be generated electrically under nonstrict conditions.

Title: Lead-containing foam and its production
Inventor: YAMAMOTO KEIICHI
IPC: C08J9/04
Filed: 1981-02-25
Abstract: PURPOSE: To obtain a lead-containing foam which is extremely light and flexible and which intercepts radiations, high frequency waves, etc., by mixing a natural rubber or synthetic rubber foam with a lead compound, a blowing agent, a crosslinking agent, an antioxidant, etc., and then foaming and crosslinking the mixture.  
     CONSTITUTION: 100pts.wt. natural rubber or synthetic rubber is mixed with at least 300pts.wt. lead compound and then with a blowing agent, crosslinking agent, a crosslinking aid, a softener, an antioxidant, etc. The mixture is aged by standing, and this uncrosslinked compound is placed in a mold. When the compound is heated therein under pressure, the blowing agent contained decomposes at a predetermined temperature, cell factors form in the compound and then a crosslinking reaction proceeds. The compound in the mold expands by a gas pressure produced by the decomposition of the blowing agent by evacuation and the heat of decomposition and pressed out of the mold. In this case, it is possible to produce closed cells and open cells, as demanded, by varying the charge of the compound in the mold. When the thus produced foam is again placed in a separate mold and heated therein, undecomposed gas is completely released, and the crosslinking reaction is brought to completion.

Abstract: PURPOSE:To simplify constitution of a tool exchanger, by a method wherein a pair of double leaf type hands energized in a closing direction by a spring is provided on the tip of an arm and a wedge obstructing a release of the hands is provided movably. CONSTITUTION:Two hands 73 supported by a shaft rotatably are provided on the tip of a main body 71 of an arm and are energized in a closing direction by a spring 77. Rear ends of the hands 73 are provided with slopes 73B and a wedge 81 connectable with the slopes is provided movably in a longitudinal direction. Although the wedge 81 is retreated through hydraulic pressure and a releasing action of the hands 73 becomes possible at the time of attachment and detachment of a tool 90, hydraulic pressure is released, the wedge 81 is advanced through a spring 83 and the hands 73 are clamped in a closed state at a holding time of the tool, through which the tool is prevented from coming off. As the hands are made into a double leaf type state by energizing with the spring, tool exchange by making use of a linear motion of a main spindle becomes possible.

Title: Processing system for control sentence
Inventor: KUMOFUJI HIROYUKI
IPC: G06F11/28
Filed: 1985-02-15
Abstract: PURPOSE:To enable the presence or absence of the nesting terminating sentences to be judged by checking the corresponding level numbers that are read when the control sentences are read, as these level numbers correspond to the sequence of the control sentences present themselves. CONSTITUTION:In a nesting constitution of the control sentence analysis loop, the frame data to be analyzed is performed by routine modules of 1-3. In each routine module, before analysis of the control sentence, the appearance or presentation sequence of previously given sentence level is read from a prescribed table in response to reading of control sentences. Since the sentence level number corresponds to the presentation sequence of the control sentences, the reasonableness of the presentation sequence can be known by checking the presentation number. In such a manner, the nesting terminating sentence can be judged, the error occurrence as from the terminating sentence can be prevented from occurring by suitable processing, while generation of redundant error messages can be prevented.
