Title: Martensitic stainless cast steel for paper-making suction roll
Inventor: SHIOKAWA HIROYUKI
IPC: D21F1/00
Filed: 1977-10-05
Abstract: PURPOSE: To enhance the corrosion resistance of a 13 Cr type martensitic stainless cast steel for paper-making suction rolls to acid by increasing the Cr content.  
     CONSTITUTION: A martensitic stainless cast steel contg. C<0.15%, Si<1.0%, Mn<1.0%, P<0.04%, S<0.04%, Cr; 13W16%, Ni; 1W3.5% and Mo; 1W2%.  The corrosion resistance of the steel to acid is enhanced by increasig the Cr content  to not less than 13% and the s-ferrite content is controlled to not more than 15%  by limiting the Cr content to not more than 16%, thereby obtaining stable martensite structure. Ni enhances the corrosion resistance, strength and toughness by  the composite effect with Cr, it, however, is limited to 1W3.5% becuase of its  high cost. Thus, the corrosion resistance of the steel to acid is enhanced and the  steel is suitable for use as a material for paper-making suction rolls

Title: Ripple elimination circuit
Inventor: ISHIGURO SHIGERU
IPC: H03F3/183
Filed: 1988-05-19
Abstract: PURPOSE:To reduce the capacitance of a capacitor and to simplify and miniaturize the shape of the capacitor by connecting a ripple filter to the base bias circuit of a transistor amplifier circuit. CONSTITUTION:A signal from a signal source A is taken out from the emitter of a transistor Q1 functioned as an emitter follower. And as the power source of the transistor, for example, a secondary voltage E from the flyback transformer of a television receiver, etc., is used. Here, a resistor R5 is connected between the collector of the transistor Q1 and a base bias resistor R1. The ripple filter is constituted of the resistor R5 and the capacitor C3 by connecting the capacitor C3 between the common point of both resistors R1 and R5 and the ground. A current which flows on the resistor R5 is the current for base biasing, and it is an extremely small current, therefore, the value of the resistor R5 can be set sufficiently larger. Therefore, it is possible to obtain a time constant required for the suppression of a ripple component even when the capacitance of the capacitor C3 is reduced.

Title: Full-automatic laser work system
Inventor: TATSUMI RIYUUJI
IPC: H01L21/027
Filed: 1978-09-29
Abstract: PURPOSE:To start automatic laser work when pattern data agrees with the pattern of an object to be worked, by moving a XY table by storing position data, pattern data and working-shape data. CONSTITUTION:Position data, pattern data and shape data are stored in control part 1. Next, control part 1 sends a movement command to XY table 51 and a shape setting command to variable slit 41 simultaneously. As a result, XY table 51 moves corresponding to the position data also adjusts the shape of variable slit 41 to a set value. Next, the pattern of worked object 6 sent from ITV camera 42 is compared with pattern data and its difference signal is sent to table driver 52. On the basis of the signal, XY table 51 adjusts finely the position and when the pattern data agrees with that of worked object 6 on XY table 51, laser unit 3 is controlled for automatic laser work.

Title: Fuel injection timing adjusting device for internal combustion engine
Inventor: ICHINOSE TOSHIO
IPC: F02D1/16
Filed: 1980-09-03
Abstract: PURPOSE: To control the rotary phase of the fuel injection pump to the engine so as to improve starting property of the engine, by providing springs which resist to an opening motion of a pair of weight which are separated apart in response to a change in rotation speed of the engine.  
     CONSTITUTION: A fuel injection timing adjusting device is provided with a case 4 rotating and joining with a main shaft of an engine while an output shaft 16 is fitted to a shaft 1 of a fuel injection pump. The case 4 is rotated by the engine and the distance between a pair of weight 14 is extended by centrifugal force against the forces of springs 22, 23. Consequently, the distance beween each of pins 13 is extended, a disk cam 5 is rotated and the position of a pin 13 is changed. Thus, it becomes possible to improve starting property and to check harmful contents in exhaust gas, because the injection timing of the fuel injection pump can be controlled  by means of a differential rotary motion generated between the case 4 and the  output shaft 16.
