Title: Pitching machine
Inventor: KARASAWA TADASHI
IPC: A63B69/40
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To stabilize a case main body by receiving the colliding energy of a hit ball at a rear side which is stable compared with the side face direction of a pitching machine and avoiding the fixing of the stocker (shooter) of a ball to the case main body. SOLUTION: The case main body 10 is provided with a ball supplying port 11 on one side face, a launching window 12 on a front face side and a pitching arm, which holds the ball B from the port 11 at a tip holding part and pitches the ball B forward from the window 12, inside. Then stockers 16 are formed like gutters to be parallel with each other, a hopper 17 is integrally fixed to one tip of the side of the port 11 and a free tip side is provided nearly in U shape to be positioned on an opposite side face by detouring rear part of the main body 10. As the stockers 16 are held freely movably without fixing to the main body 10, colliding energy made by the hit ball can be absorbed even when the ball collides to the main body 10.

Abstract: PURPOSE:To form minute holes not to be polluted by impurities by a method wherein the P doped oxide film as an interlayer insulating film is covered with the poly Si mask to each the connecting holes. CONSTITUTION:A poly Si thin layer 32 is laminated on an insulating film 22 on a substrate provided with a diffused layer 12 and provided with a resist mask 42 to perforate said layer 32 without undercut.

IPC: H04L7/00
Filed: 1995-03-16
Abstract: PURPOSE: To shorten the time needed for transmission of the synchronism detection data and also to reduce the processing burden of a CPU. CONSTITUTION: A 1st decision processing part 10 compares the continuous 16 bits contained in the received data with the first half of the PN31 code data to decide the first half error number. The part 10 also serves as a hardware processing part which outputs a detection signal when the first half error number is kept in a 1st prescribed error number range. A 2nd decision processing part 20 compares 15 bits following 16 bits of the received data with the latter half of the PN31 code data to decide the latter half error number in response to the detection signal. Then the part 20 decides that the N-bit received data are coincident with the PN31 code data when the sum of the first and latter half error numbers is kept in a 2nd prescribed error number range.
