Filed: 1990-08-02
Abstract: PURPOSE:To obtain a smooth magnification change effect by selecting a 2nd zoom means automatically when a 1st zoom means reaches a predetermined magnification and selecting a camera output from a 1st video signal to a 2nd video signal. CONSTITUTION:When a magnification of a 1st zoom means 1 magnifying the magnification with a control signal (n) of a control means 10 in response to a tele signal (g) of a zoom switch 11 reaches a changeover base point magnification A, a magnification detection circuit 12 inputs a tele-end signal to the control means 10.

Title: Method for preventing width camber in steel strip rolling
Inventor: ONO MASAO
IPC: B21B37/28
Filed: 1988-08-22
Abstract: PURPOSE:To prevent uneven wear of work rolls in a steel strip rolling and to obtain a good shape rolled stock without width combers by bringing a parallelism of a work roll rolling the strip and an adjacent roll being in contact with the work roll to have a cross angle not more than a specific angle. CONSTITUTION:A cross angle theta is a twisting angle between axises of the work and reinforcing rolls; hence, theta=0 means that the work and reinforcing rolls are parallel. By bringing the cross angle to be <=0.06 deg., width cambers of a steel strip generated in skin pass rolling, etc., are prevented. A steel strip 5 is rolled by a rolling mill provided with a roll parallelism detector and a roll parallelism adjuster and a cross angle theta is variedly changed. As the result, if a roll parallelism between the rolls 1, 2 is adjusted so that 0 deg.<=theta<=0.06 deg., a roughness difference between upper and lower work rolls 2, 4 is limited not to be more than a specific value. Thus, uneven wear of the work rolls is prevented and a good shaped rolled stock without width cambers is obtained.

Title: Semiconductor device and its manufacture
Inventor: IKEMASU SHINICHIROU
IPC: H01L27/108
Filed: 1994-08-31
Abstract: PURPOSE: To round the angles of the through hole by permitting a through hole to be formed on an SiN film and a silicon oxide film which contains at least boron or phosphorus to be a polygon with only n obtuse angles (n) is a natural number of 5 or more) on a reticle. CONSTITUTION: The size of a contact hole is 1μm or less. When an opening is approximately of this size, the pattern actually exposed on a wafer becomes almost circular, even when the pattern is square on a reticle. Therefore, the angles of the contact hole become round. Thus, when the contact hole is permitted to be a polygon with n obtuse angles (n) is a natural number of 5 or more), the angles of the contact hole can be rounded.

Title: Separator for storage battery
Inventor: MUTOU JIYUNSUKE
IPC: H01M50/437
Filed: 1983-11-04
Abstract: PURPOSE:To increase the electrolyte retention force at the upper part of a separator by making the average diameter of the upper fiber type material smaller than that of the lower one and forming a separator for a storage battery in which the fiber type material is intertwined and is formed into a sheet shape. CONSTITUTION:When a separator 10 for a storage battery in which glass fiber is intertwined and is formed into a sheet shape is formed, the glass fiber whose average diameter is 1mum or less is used as the entire separator. At the same time, the upper part 11 of the separator is mainly composed of narrow diameter glass fiber whose average fiber diameter is 0.3-0.6mum and the lower part 13 is mainly composed of large diameter glass fiber whose average fiber diameter is 0.7- 1.0mum and then the central part 12 contains almost the same amount of both of abovementioned sorts of fiber. As a result, the electrolyte retention force based on the upper capillarity can be improved by reducing the upper fiber diameter and, even in the case of a battery with a high plate, the electrolyte distribution can be made even and its high performance can be maintained.

Title: Correcting device of error in detected position
Inventor: WATABE MITSURU
IPC: G05D3/12
Filed: 1984-10-04
Abstract: PURPOSE:To make it possible to detect an accurate position and to improve position detecting performance, by correcting hysteresis errors at the time of waveform processing and errors occurring at the time of displacement counting based on the instantaneous value of the original signal of a position detector. CONSTITUTION:An instantaneous-value detecting circuit 103 samples and holds detected original-position signals eA and eB and a specified-value signal eC at every sampling in waveform processing. The analog quantity is converted into digital quantity and an instantaneous-value signal T4 is detected. A turning- absolute-position detecting circuit 104 compares the instantaneous-value signals T4 from the circuit 103. A position, where a rotary body is present at the time of sampling, is obtained as a sector number (m). The number is decoded and a turning-absolute-position signal T5 is obtained. A position correcting circuit 105 subtracts the signal T5 from counted displaced-pulse signal T3 and divides the result by 4 and obtains the remainder. The position correcting quantity with respect to the signal T3 is obtained from the remainder value. Thus, correction is performed, and a position signal T4 is obtained and outputted.

Filed: 1989-08-10
Abstract: PURPOSE:To visibly observe the status change of a high speed signal by detecting the changing point of a signal, holding the detected changing point, reading out the held contents in a prescribed period, and displaying the read result with lighting. CONSTITUTION:A changing point detecting circuit 20 detects the changing point 31 of a signal 30 and a holding circuit 21 holds a detecting signal 32 indicating the detection. A reading part 5 reads out the contents of the circuit 21 in the prescribed period and clears the read contents in each reading. After cleared, the changing point 31 of the signal 30 is stored in the holding circuit 21 again. A display control part 11 displays the contents read out of the circuit 21 with lighting at the time of the detection signal 32, or turns off light at the time of its clear state. Since the changing point 31 of the signal 30 generated at the timing other than a reading timing is detected and displayed, the status change of a high speed signal can surely be displayed.
