Title: Alignment pattern formation
Inventor: NAKAJIMA MASAYUKI
IPC: H01L21/306
Filed: 1988-10-11
Abstract: PURPOSE:To form highly accurate alignment pattern by forming a specified pattern by first etching or first and second etchings, and forming an alignment pattern by the second etching. CONSTITUTION:A photoresist 4 is formed on a ground layer 2 and pattern holes 40 and 41 are formed, and hard baking is applied. Next, only the pattern hole 41 is buried by a resist pattern 5 and is heat treated. And using wet etchant, isotropic etching is done from the surface below the pattern hole 40 down to the central part. The ground layer 2 below the pattern hole 41 is not etched. Next, the whole face of a substrate 1 is exposed and developed, and the resist pattern 5 is removed selectively and again a pattern hole 41 is formed. And with the photoresist 4 having the pattern holes 40 and 41 as a mask, anisotropic etching is done to the round layer 2. As a result, the ground layer 2 below the pattern hole 40 is etched vertically without dimension shift, and the part below the pattern hole 41 is etched vertically from the surface down to the rear.

Title: Transistor amplifier
Inventor: HASHIMOTO MASAAKI
IPC: H03F3/45
Filed: 1987-10-09
Abstract: PURPOSE:To improve the gain and the frequency characteristic by using a 1st differential connection circuit so as to amplify an input voltage differentially and using a 2nd differential connection so as to amplify the voltage differentially. CONSTITUTION:Input voltages Vi1, Vi2 given to bases of transistors(TR) Q5, Q6 are amplified by TRs Q5, Q6 and Q3, Q4 and output voltages V01, V02 are outputted from collectors via TRs Q7Q8. Then a current flowing to a resistor RL1 is controlled by the TRs Q4, Q5 and the current control of both the TRs is implemented in phase. Similarly, the current control of the TRs Q6, Q3 controlling the current flowing to the resistor RL2 is implemented in phase and opposite to the current control of the TRs Q4, Q5. Thus, the gain of the differential connection circuit comprising the TRs Q3, Q4 is added to the gain of the differential connection circuit comprising the TRs Q5, Q6. Since the base of the TRs Q1, Q2, Q7, Q8 is kept to a constant potential by a constant power supply VS, the change in the collector potential attended with the change in the collector current of the TRs Q3-Q6 is suppressed and the mirror effect by collector-base parasitic capacitance of the TRs Q3-Q6 is reduced.

Title: Dc level stabilizing circuit
Inventor: ICHIMURA HIROSHI
IPC: H04N5/16
Filed: 1992-08-31
Abstract: PURPOSE:To prevent a noise produced in a line cycle by supplying a clamp pulse to a comparator constructing a digital clamping circuit in each vertical scanning period. CONSTITUTION:A sawtooth wave signal (a) is inputted through an input terminal In1 of a digital clamping circuit 1 which constructs a DC level stabilizing circuit. Thus the reference data is supplied to a comparator 16b through an input terminal In3 and at the same time a clamp pulse (d) is supplied to the comparator 16b through an input terminal In2. The pulse (d) is supplied once or several times at each vertical flyback time and at the start of a scanning period. The comparator 16b compares the pulse (d) with the reference data and then supplies the comparison output as a correction signal (b) to an adder/subtractor 16c via an averaging circuit 16d. The adder/ subtractor 16c performs the addition and the subtraction when the level to be clamped is low and high respectively to obtain the clamp output (c). Thus it is possible to prevent the noise which are produced in a line cycle.

Title: Transfer device
Inventor: MIWA MASATO
IPC: G03G21/10
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To extend the lives of a transfer material carrying belt and a cleaning device by holding the cleaning device rotatably around the shaft circumferential part of one rotating member of a plurality of rotating members. SOLUTION: A cleaning blade 5a is engagingly locked through a blade holder 5b in such a manner as to be rotatable around the rotating shaft of an auxiliary roller 4. Thus, the position of the end of the blade 5a is properly designed, whereby a state where the blade 5a does not make contact with a transfer material carrying belt 1 in printing operation, and makes contact with the belt 1 in waiting can be provided. Since a developer 12 on an image carrier 11 is almost transferred onto the transfer material when the printing operation is normally performed, the belt 1 is never contaminated, and no serious problem arises even when the end of the blade 5a is not in contact with the belt 1. To the contrary, when the developer 12 on the image carrier 11 is directly transferred onto the belt 1 by a carrying failure of transfer material, cleaning is necessary.

Title: Hot rolled steel sheet excellent in adhesive strength of scale and its manufacture
Inventor: TANAKA AKIRA
IPC: C21D8/02
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To manufacture inexpensive hot rolled low carbon and medium carbon steel sheets excellent in the adhesive strength of scale by specifying the composition of the steel sheet and mean roughness of the surface of the steel sheet. SOLUTION: The hot rolled steel sheet excellent in the adhesive strength of scale contains, by mass, 0.05-0.2% C, 0.005-0.5% Si, 0.01-1.5% Mn, 0.001-0.1% P, 0.001-0.03% S, 0.001-0.1% Al, 0.0005-0.005% N and the balance Fe with the elements of inevitable impurities, the mean roughness Ra of the surface of the steel sheet is taken as <=2.0 μm and PPI as <100. It is considered that the adhesive strength of scale depends on the state of the boundary between the base iron and scale at the time of generating secondary scale and the reason is considered that the adhessive strength of scale is improved by a cause that the scale generated during hot rolling is uniformly elongated, but cracking and peeling in the scale are hardly generated. Consequently, the hot rolled steel sheet excellent in the adhesive strength of scale is obtained and utilization value in industry is extremely high.

Title: Search controller
Inventor: NAKAMA YASUHEI
IPC: G11B15/467
Filed: 1987-10-14
Abstract: PURPOSE:To enable cylinder rotation tracking control to be performed again by setting relative speed between a tape and a head so as to be controlled within the lock range of a PLL, by decreasing the feed speed of the tape when tape feed and rotary head tracking control is out of control in fast search. CONSTITUTION:A cylinder 1 is set at the FG (frequency generator) control (constant speed servo of 200rpm) of an ordinary reproducing mode even when the PLL 11 is set at an unlocked state once by the overload of a tape feed system or the missing of a recording signal, etc. Furthermore, control is switched to low tape feed speed control where recording data can be read at the cylinder rotating speed sufficiently by the heads 2A and 2B. Therefore, it is possible to perform the re-pull-in of PLL locking immediately after the recording signal appears, and to shift an operation to the fast search smoothly. In such a way, it is possible to prevent a case where the fast search is impossible to be continued from being generated due to the unlocking of the PLL.
