Inventor: TADA MASASHIGE
IPC: H03L7/093
Filed: 1994-10-31
Abstract: PURPOSE: To set an output voltage over wide ranges by controlling the conduction/cut-off of a current path and loading a source operation to let a current flow from a first power source to an output terminal or a sync operation to let a current flow from the output terminal to a second power source. CONSTITUTION: When a transistor T2 is turned on, a power supply path CLA composed of a constant current source 1 and a current mirror circuit 4 is turned to a conducted state but when the transistor T2 is turned off, that CLA is turned to a non-conducted state. When the transistor T2 is turned on, the current of a current amount 11 to be supplied from the constant current source 1 through the path CLA flows as the collector current of a transistor T6. Namely, transistors T1 and T2 control the conduction/cut-off of the path CLA. When a transistor 4 is turned on, a current path CLB between a constant current source 2 and a current mirror circuit 5 is conducted but when the transistor 4 is turned off, that path CLB is not conducted.  When the transistor 4 is turned on, the current of the current amount I1 to flow through the path CLB flows as the collector current of a transistor T8, and transistors T3 and T4 control the conduction/cut-off of the path CLB.

Title: Video scramble deciphering device
Inventor: KAZAMA HIROYUKI
IPC: G06F21/10
Filed: 1987-10-22
Abstract: PURPOSE:To process a normal video signal and a scramble video signal in the same clamping circuit by providing a circuit for forming a clamping pulse at the time of inputting the normal video signal and a circuit for forming the clamping pulse from a key signal at the time of inputting the scramble video signal. CONSTITUTION:A scramble video signal processing is similar to the conventional example. In case of a normal video signal processing, the inputted normal video signal is inputted to the clamping circuit 11 similarly to the scramble video signal. Under an initial state, since there is no clamping pulse 20, it is not processed but outputted via the clamping circuit 11, a polarity inverting circuit 12, a synchronization shifting circuit 13 and an output circuit 15 and inputted to a clamping pulse generating circuit 19 at the time of the normal signal. The clamping pulse circuit 19 synchronously separates a video output signal 4 to output the clamping pulse 20 formed by controlling a horizontal automatic frequency locked to a phase to the clamping circuit 11. Consequently, a pedestal clamp is applied to the normal video signal inputted in the clamping circuit 11 to remove a dispersal.

Title: Multi-amplifier system with buffer
Inventor: TSUBOI AKIRA
IPC: H04R3/00
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To eliminate the distortion of the network system of a multiway speaker system. SOLUTION: An amplifier (voltage amplification is not required) is put between the network of the network (filter) system of the multiway speaker system and a speaker. Thus, since the respective values of the coil, capacitor and load resistor of the network become unrelated to the impedance of a speaker unit, a set value becomes substantially free and miniaturization, weight reduction and cost reduction are performed. Since load resistance is pure resistance, filter characteristics are improved.

Title: Single ftheta lens
Inventor: FUJITA HISAO
IPC: G02B13/18
Filed: 1984-12-21
Abstract: PURPOSE:To obtain an ftheta lens which has sufficient performance with simple single-element constitution even when its refractive index is <=1.6, and can be molded out of even a plastic material by specifying the relation among the focal length, deviation from a surface with a radius of paraxial curvature as an object-side surface, and deviation from a surface with a radius of paraxial curvature as an image-side surface. CONSTITUTION:On a single lens which is provided with an entrance pupil in front of the lens and has positive power, at least one surfacve is made aspherical surface and satisfies an inequality 1. In the inequality, (f) is the focal length, DELTAX1 is the deviation from the surface with the radius of paraxial curvature as the object-side surface, and DELTAX2 is the deviation from the surface with the radius of paraxial curvature as the image-side surfade; and an equation (2) holds. Subordinately, -0.5<f/R1<0.5 (R1: radius of paraxial curvature on object side) and the single ftheta lens satisfying the inequality is constituted. The upper limit of the inequality 1 is a limit for obtaining the correction effect of an merdional image plane and the lower limit is a limit where the compensa tion becomes excessive and a limit for preventing the distortion aberration from becoming too positive.

Title: Axial flow turbine
Inventor: TAKENAGA HISAKUNI
IPC: F01D9/02
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To improve the flow of steam entering from a speed governing stage nozzle to a high pressure first stage nozzle and enhance the performance of axial flow turbines used in steam turbines and gas turbines. SOLUTION: High temperature and high pressure steam expands in a speed governing stage nozzle 10, flows through a speed governing stage moving blade 20 to work, flows from a chamber 7 into a high pressure first stage nozzle 30, works on a high pressure first stage moving blade 40, enters into a high pressure second stage nozzle 50, then similarly works on a high pressure second stage moving blade 60, to rotate a turbine rotational axis 80. The speed governing stage nozzle 10 has a circumferential nozzle with an inlet portion and a non-inlet portion for steam. The steam flowing from the non-inlet portion is mismatched with the flow direction of the high pressure first stage nozzle 30, to degrade performance.  Therefore, a plurality of guide vanes 100 are positioned circumferentially just before the non-inlet portion of the high pressure first stage nozzle 30 so as to align the flow from the non-inlet portion with that from the inlet portion, solving the mismatching problem, making steam flow into the high pressure first stage nozzle 30, and thereby preventing degraded performance.

Title: Pcm reproducing device
Inventor: SUGANO HIROSHI
IPC: H04B14/04
Filed: 1985-11-29
Abstract: PURPOSE:To reduce the distortions of the reproduced analog signal that are caused by the excessive correction by using the error probability information on a decoding mode and the weight of each signal block to decide the necessity for correction of the word value. CONSTITUTION:A decoder 6 first calculates the error symbol number NZ from the input signal and then delivers '0' in the form of the error probability information 6b because no error symbol exists when the number NZ is equal to '0' and the symbol reliability is high. While the single error correction is carried out when the NZ is equal to '1' and '0' is delivered as the information 6b because the error correction probability is small with the single error correction. Then the double error correction is carried out when the number NZ is equal to 2. In this case, '1' is delivered as the information 6b because the error correction probability is large. An error symbol is always included when the NZ is equal to >=3 and 2 is delivered as the information 6b. However the rearrangement like the interleave, etc. is usually carried out in a coding mode. Then the information 6b is delivered in response to the symbol delivered from the decoder 6.

Title: Adaptive circuit for discriminating period signal
Inventor: MACHIASU MUTO
IPC: G01P3/48
Filed: 1990-10-09
Abstract: PURPOSE: To generate a highly reliable signal in the case of various kinds of interferences by generating an output signal that is proportional to the fundamental vibration of a periodical signal according to whether the periodical signal matches with a reference value formed by an average value generation circuit or not. CONSTITUTION: An evaluation circuit 11 performs A/D conversion 14 of a periodical signal Us and detects whether a maximum value or a minimum value (extremely value) has passed or not by an extreme value identification member 15. At this time, the circuit 11 responds to only a minimum turnover voltage UM after passing the extreme value, thus compensating for a small interference. However, when the interference is large, the output signal of the member 15 is supplied to an accumulation member 17 of an average value circuit 12 as a clock signal or a charge pulse signal. The member 17 receives a signal value from a division part 18 and supplies a reference value UV to a comparator 13 and an addition part 16.  The addition part 16 continuously adds a signal US and a charge pulse signal from the member 17, namely a signal value corresponding to a final extremely value, inputs it to the member 17 through the division part 18 as a new reference value UV, a comparator 13 generates a variable signal at each moment when the reference value UV matches the signal US, and an output signal U is formed correspondingly.
