Title: One-side plating method
Inventor: NAKAZAWA MASAO
IPC: C25D5/02
Filed: 1990-05-29
Abstract: PURPOSE:To easily apply plating on one side face of a body to be plated by immersing end parts of a plate body to be plated and a rigid plate which are disposed in proximity into a plating liquid and filling the plating liquid by capillarity into the microspacing between both. CONSTITUTION:The plate body 2 to be plated for a tape, etc., for TAB formed with conductor patterns of copper foil 3 on an electrical insulating film 9 and the rigid plate 1 having rigidity are disposed in proximity via a spacer 8, etc., and the respective ends thereof are immersed into the plating liquid 4. The plating liquid 4 is filled by utilizing the capillarity into the microspacing 5 formed of the one side face of the rigid plate 1 and the one side face of the body 2 to be plated. The microspacing 5 is adequately about 0.5mm. The entire surface of the one side face of the body 2 to be plated is thereby substantially brought into contact with the plating liquid 4. A plating current is supplied between the body 2 to be plated as a cathode and the anode 6 by a power source 7. The plating is easily applied on the one surface of the plate body 2 to be plated in this way.

Title: Trigger circuit of static induction thyristor
Inventor: KOMODA TAKUYA
IPC: H03K17/73
Filed: 1986-06-14
Abstract: PURPOSE:To attain high speed turn-off by connecting a resistor between the emitter and base of a PNP transistor (TR) whose emitter and collector are connected to gate and cathode of a static induction thyristor so as to apply a control pulse to the base. CONSTITUTION:The static induction thyristor Ts is connected in series between a power supply E and a load L. The gate and cathode of the thyristor Ts are connected respectively to the emitter and collector of a PNP TR Q3. A resistor Rs is connected between the gate and emitter of the TR Q2 and the gate of the TRQ2 is applied with the voltage across it. When a base input of a NPN TR Q1 goes to L, the TRQ1 is turned off, a trigger current flows to the thyristor Ts via resistors R1, Rs from the power supply Eg to turn on the thyristor Ts. When the base of the TRQ1 goes to H, the TRQ1 is turned on to draw the gate current of the thyristor Ts rapidly to turn on the TRQ2 thereby turning off the thyristor Ts. Thus, high speed turnoff is executed surely.

Title: Method for controlling plate width
Inventor: FUJIZU TAKESHI
IPC: B21B15/00
Filed: 1987-06-04
Abstract: PURPOSE:To edge the top and rear end parts of a steel slab and to prevent excessive width spread of the top and rear end parts by predicting a spread amount of the top and rear end parts of the slab at the inlet side of a rough rolling mill and edging the ends into a narrower width than a width of the intermediate part. CONSTITUTION:A slab 1 with a width Ws is edged by anvils 2 having an inlet side tilt angle theta1 and an outlet side tilt angle theta2. First, the top of the slab 1 is edged by an excessive amount of  d1 more than a single side edging amount of  W/2 of the intermediate part by use of the inlet side tilted part theta1. Then, the intermediate part of the slab 1 is edged by use of the part theta1 and the intermediate parallel part of the anvils 2. Finally, the rear end part of the slab 1 is edged by use of the outlet side tilted part theta2 by an excessive amount  d2 more than the single side edging amount  W/2. The top part  d1 and the rear part  d2 of the slab 1 after pressing are considered to be canceled with spreads of the top and rear end parts caused by rough and finishing rollings in the succeeding stage, so that excessive width spreading is prevented.

Title: Method for detecting end point in dry etching and method for forming contact hole using it
Inventor: TAMAOKI NORIHIKO
IPC: H01L21/3065
Filed: 1990-05-29
Abstract: PURPOSE:To enable etching end point of a specific layer to be detected by forming a silicon nitride film below a specific layer to be subjected to dry etching previously and by measuring a CN light-emitting spectrum which is generated by the silicon nitride film being subjected to dry etching for determining end of etching of the specific layer. CONSTITUTION:A BPSG film 7 is etched vertically with a photo resist 4 as a mask. When the BPSG film 7 is eliminated and a silicon nitride film 6 is exposed. CO light-emitting spectrum is reduced and the CN light-emitting spectrum is increased. A contact hole 8 reaching an n<+> diffusion layer 2 of an impurity diffusion layer is formed by switching etching conditions for suppressing ion energy of an ion entering a substrate. Since a nitride film 6 is formed below the BPSG film 7 of the insulation film as a specific layer which should be subjected to etching elimination corresponding to a part where the contact hole 8 is to be formed, end point of etching of the BPSG film 7 can be determined accurately by measuring the CN spectrum which is generated from this silicon nitride film 6.
