Patent JP-S6350017-A (JP)
Title: Automatic focus detector
Inventor: OGAWA SHIGEKI
IPC: G03B27/34
Filed: 1986-08-20
Abstract: PURPOSE:To enable the surface of an object to be registered to the focus posi tion with high precision and in a short period of time, by utilizing a value of a distance between a lens and the image forming surface measured in the prior shot for performing the focus drive. CONSTITUTION:A wafer 6 has rectangular regions 1-32 each of which is a pattern region to be exposed by one shot. The wafer 6 is moved step by step along the X-and Y axes so that it is printed in sections. When each shot region is printed, a decreasing projection lens 1 and air sensor nozzles 2-5 are positioned for example as shown in the drawing. In order to print the region S for example, a distance between the next region 28 and the lens 1 is measured by the nozzle 2. The distance is stored in a memory so that the region 28 is registered for printing thereof by using this stored value measured by the nozzle 2 when the region S is printed. In this manner, focusing can be performed with high precision and in a short period of time even in the peripheral region of the wafer 6 where a large warpage is generated.

Title: Data transfer control system
Inventor: HASHIMOTO SHIGERU
IPC: G06F13/38
Filed: 1984-09-14
Abstract: PURPOSE:To attain the transfer of data at a high speed by producing plural read addresses in response to read start addresses to output the corresponding read data and at the same time sending plural answer signals back to a transmission strobe in response to the data output. CONSTITUTION:A memory element 20 receives the start address on an address bus A-BUS and the address of lower 2 bits from an address counter 25 via a receiver 23 and performs an access. Thus the corresponding data is sent to a data bus D-BUS from the memory 20. At the same time, a memory control part 22 produces an answer signal SRVO through a memory access control part 22b and outputs it to an answer signal line C1. Then a counter 22a which counts the output frequencies of the answer signals for each strobe and the counter 25 are counted up in a memory 2, and an access is given to the next word of the element 20. Thus the count value of the counter 22a reaches '4', and the data are delivered four times. In other words, the answer signals are delivered four times. Thus the part 22b stops the access of the element 20.

Filed: 1982-11-04
Abstract: PURPOSE:To prevent the deterioration of the characteristics of an active element by removing the polishing layer of the surface of the glass substrate through etching before forming a semiconductor thin-film such as a silicon thin-film.

Filed: 1991-08-02
Abstract: PURPOSE:To prevent a negative score from increasing in size by allowing the profile of a character to be changed by the amount of + or - one picture element under a specific restriction. CONSTITUTION:An exclusive OR gate 102 checking the incoincidence between a picture element sm, n of an input character pattern and a picture element rm, n of a reference character pattern corresponding to it, an adder 117 counting the number of incoincident picture elements, gates 103 to 114 checking the picture element surrounding the sm, n and the picture element surrounding the rm, n and a gate 115 blocking the output of the exclusive OR gate 102, are provided. In this case, when the change of the profile of the input character pattern is such that any output of the gates 105, 108, 111 and 114 is '1' even when the incoincidence between the sm, n and the rm, n takes place due to the change of the profile of the input character pattern, such picture element is not added to the number of incoincident picture elements.

Abstract: PROBLEM TO BE SOLVED: To easily and surely assemble a weight consisting of another material to a head body consisting of titanium or titanium alloy of a head of a metal wood or the like. SOLUTION: A receiving body 22 consisting of the titanium or the titanium alloy is interposed between a main body shell member 18 and weight 21 constituting the head body. The weight 21 is caulked and joined to the receiving body 22 and thereafter the receiving body 22 is welded to the inside surface of the main body shell member 18. As a result, there is no more restriction on the material of the weight 21 although the fixation to the main body shell member 18 is executed by welding. The caulking of the weight 21 and the receiving body 22 is effected by press fitting the weight 21 into a recessed part 24 formed at the receiving body 22 and penetrating the pawl part 25 formed at the receiving body 22 into the weight 21.

Title: Fault detector
Inventor: KONOHI HAJIME
IPC: G01R31/02
Filed: 1983-10-18
Abstract: PURPOSE:To detect instantaneously a fault of an ADPCM coder by using an ADPCM decoder to monitor the input and output signals of the AD PCM coder. CONSTITUTION:The PCM signal supplied from a PCM input terminal 101 is applied to an ADPCM coder 1 as well as to the 1st sound detector 4 of a fault detector 2. The detector 4 amplifies the sound PCM signals to a level higher than a fixed level, and this amplification output is applied to one side of a comparator 6. While the sound PCM signal converted into a code by the coder 1 is delivered from an ADPCM output terminal 102 and also supplied to an AD PCM decoder 3 to be decoded to a PCM signal. When this decoded PCM signal exceeds a fixed level, this PCM signal is applied to the other side of the comparator by the 2nd sound detector 5. The comparator 6 compares the input with the output of the coder 1. Then an alarm detector 7 decides whether the comparison result of the comparator 6 is set within a fixed range of errors. When a fault is detected, an alarm is delivered.
