IPC: B21K21/08
Filed: 1983-11-16
Abstract: PURPOSE:To obtain a tooth form having high ccuracy from a rough material having low accuracy by packing a liquid pressure medium in a hollow rack rough material, executing a press work by an enchlosed forging means, and compensating a part of an escape of a metal by plastic deformation by a discharge of a pressure medium. CONSTITUTION:A hollow rack rough material 4 is fitted to a space of a die 1 and side dies 2, 3, a pressure-resistant valve body 5 is fitted to the die 3, a liquid pressure medium is pressed into a hollow part of the rough material 4 from a conduit 2b, and the valve body 5 is supported elastically by a plate spring 6. Subsequently, a punch 8 is lowered, forming of a surface to be worked 4a of the rough material 4 by a punch 9 having a tooth form on the lower face, and when a liquid pressure of the inside of the rough material 4 reaches a prescribed value by raising gradually a press pressure, the valve body 5 slides against the spring 6, and a pressurized liquid is discharged from a thin hole 5c. In this case, a discharge quantity of the pressurized liquid is made equal to an advance capacity to the rough material of the punch 9, and the liquid pressure is maintained at a prescribed value. In this way, a tooth form having high accuracy is obtained by using a hollow rough material having low accuracy so that no burr is generated.

Title: Synchronized digital converter
Inventor: WATANABE YUICHI
IPC: H03M1/64
Filed: 1994-09-09
Abstract: PURPOSE: To convert a synchronized signal into a digital signal accurately even when an error signal is set to OV by providing a polarity detector and a 0 deg./180 deg. correction circuit because the phase of an input signal changes from 0 deg. to 180 deg. or vice versa. CONSTITUTION: A Scott connection transformer 1 converts received synchronized signals 10-12 into resolver signals 15,16. When the phase of the synchronized signals 10-12 changes rapidly from 0 deg. to 180 deg. or vice versa, an error signal 19 remains 20. Thus, an up-down counter 8 does not revise angle data 20. In this case, a phase detector 6b is used to eliminate the reference signal 18 from the 2nd resolver signal 16 and a polarity detector 22 discriminates the polarity of an input voltage. Since an angle signal 21 in an output buffer 9 indicates 0 deg., when the polarity detector 22 detects positive polarity, a 0 deg./180 deg. correction circuit 23 provides digital angle data of 0 deg. and when negative, the circuit 23 provides an output of angle data of 180 deg..

Title: Semiconductor storage device
Inventor: FUJITA MASAMORI
IPC: G11C29/00
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor storage device improved in the efficiency of a defect relieving means, improved in yield and switchable in the width of data input/output by selecting either of the memory cell or the redundant cell by the output of a comparing means and changing the number of digits to be compared by a comparing means in external address signals by linking the comparing means to an input/output data width changing means. SOLUTION: When an MDX4 signal is at the high level and the redundant cell included in the ARRAY0 is substituted, the YRSEL0 signal acquires the high level and the DAE0 signal is activated. When the redundant cell included in the ARRAY1 is substituted, the redundant cell included in the ARRAY1 is not substituted and accordingly the YRSEL0 signal is brought to the low level. By this the DAE0 signal becomes a low level signal and is not activated. When no substitution is performed, both the YRSEL0 and the YRSEL1 are brought to the low level.

Abstract: PURPOSE:To enable a silicon wafer to be positioned with high speed and accurately anywhere by attracting the silicon wafer with an attracting disc and a little lifting it and further rotating the attracting disc by a definite angle on a referential position where an end part of orientation flat is detected during a disc rotating operation by a phetoelectric detector mounted on a susceptor. CONSTITUTION:A silicon wafer 30 placed on a susceptor 6 is lifted a little by an attracting disc 8. At that time, air is sucked through the attracting holes 8a of the attracting disc 8 and so the silicon wafer 30 is attracted on the attracting disc 8. Then the attracting disc 8 is rotated in the constant direction through a rotary shaft. Thus the silicon water 30 is rotated on the position slightly above the susceptor 6 and concurrently an end part of an orientation flat 31 is detected by a photoelectric detector 7 in a controlling circuit in which a photoelectric signal outputted from the photoelectric detector 7 is inputted. The attracting disc 8 is rotated further by a constant angle from the present position by the operation of the controlling circuit. Hence, the forward and backward positions for the silicon wafer 30 can be exactly determined.
