Title: Method for driving display device
Inventor: TSUKADA TAKASHI
IPC: G02F1/133
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a driving system which suppresses the occurrence of unevenness in luminance of thin lateral lines in lines of simultaneous selection parts of thin line luminance unevenness scan signal electrode lines, which occur due to dropping of a picture element voltage by an influence of fall to a selection gate voltage in one line of simultaneously selected scan electrode lines, and makes unevenness in luminance approximately inconspicuous even for the change of the luminance level with respect to a system where simultaneous selection of partial scan signal electrode lines is repeated to perform zoom display. SOLUTION: A period when adjacent scan signal electrode lines are simultaneously selected is provided, and the non-selection timing of the scan signal electrode line side to which an auxiliary capacity is connected is denoted as t1 and that of the scan signal electrode line side connected to a switching element is denoted as t2 with respect to selection periods of simultaneously selected scan signal electrode lines; and when a non-selection reference voltage of scan signal electrode lines or a reference voltage to counter electrodes is variably controlled from a timing t12 between timings t1 and t2 to a timing t3 after the timing t2 and in one horizontal synchronizing period, thus variable control is linked with the luminance adjustment level of a display device.

Title: Protection system
Inventor: TAKAHASHI SUSUMU
IPC: G06F11/00
Filed: 1988-01-22
Abstract: PURPOSE:To avoid the malfunction of a protector circuit at runaway of an MPU by releasing a protector after detecting fact that the MPU applied the accesses to the continuous addresses in the descending power order. CONSTITUTION:A holding means 2 detects that the continuous addresses which are set an output port from a CPU 1 via a decoder 3 are received in the descending power order in a protection system where the unfixed output is prevented until the result of execution of the CPU 1 is delivered from an OUT terminal by noting that a program counter of the MPU 1 is always increased successively at runaway of the MPU 1. Then a gate 5 is opened and the data held by a register 4 are delivered. Thus the continuous addresses ascend successively owing to said noting point at runaway of the MPU 1. As a result, the gate 5 is never opened.

Title: Power supply for traveling wave tube
Inventor: IWANAMI YOSHITOMO
IPC: H01J23/34
Filed: 1991-02-04
Abstract: PURPOSE:To enhance the reliance upon the performance of a traveling wave tube by using a power supply therefore which is equipped with a sequence control circuit, and conducting sequence control for the rising and falling of the output voltage. CONSTITUTION:Through a cathode current, sensing circuit 4 a sequence control circuit 5 distinguishes that the cathode current is the cut-off state, and emits a start signal for the power supply 2 for a helix collector electrode. Also through a cathode voltage sensing circuit 3, the control circuit 5 distinguishes that the helix collector voltage has risen, and gives instruction to start the power supply 1 for anode electrode. This sequential control suppresses turbulence in the beam of a traveling wave tube, and no eddy current shall necessarily flow to the helix. When the supply voltage is to fall, the control circuit 5 distinguishes with the aid of the cathode current sensing circuit 4 that the traveling wave tube is the On state, and emits a stop signal for the power supply 1. Then the control circuit 5 checks from the output signal of the cathode current sensing circuit 4 that the beam current is in Off state, and gives a command to stop the power supply 2. This allows suppressing turbulence in the beam current.

Title: Absorber for air-cooled absorption type refrigerating unit
Inventor: OKUDA NORIYUKI
IPC: F25B37/00
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To achieve a lowering of manufacturing cost by simplifying a joint structure of a shell body for an absorber and a communication pipe in the absorber for an air-cooled absorption type refrigerating unit. SOLUTION: A communication pipe 22 is inserted into a mounting hole 54 provided in a bottom wall 52a of a shell body 52 for an absorber in such a manner that the upper end part 22a thereof protrudes out to the side of an absorbing liquid distribution chamber 6 from the top surface of the bottom wall 52a while the communication pipe 22 and the shell body 52 for the absorber are joined and fastened by resistance welding. With such an arrangement, this eliminates the need for relatively costly silver solder material as required by the conventional structure using silver soldering even when the joint between the shell body 52 for the absorber made of ferrous medal and the communication pipe 22 made of non-ferrous metal is a hetero-metal joint.  There is no need for the work of removing flux or the like as post treatment or the work of removing thermal distortion attributed to a difference in heat capacity during the joint. This simplifies the working of joining the communication pipe 22 on a bottom wall 52a of the shell body 52 for the absorber, ultimately enabling a lowering of manufacturing cost during the production of the absorber.

Title: Hydraulic control device of rolling mill and rotary valve used therein
Inventor: NOGAMI TADAHIKO
IPC: F16K11/074
Filed: 1992-01-29
Abstract: PURPOSE:To provide high control performance and reliability and also to facilitate manufacture by properly holding a clearance between a valve unit and a side plate, in a rotary valve. CONSTITUTION:A valve unit 21 is provided to be interposed by side plates 22, 23, to provide thrust bearings 28, 29 between the valve unit 21 and the side plates 22, 23 and high pressure action parts 30, 31 in a back surface of the side plates 22, 23. Since a pressure receiving area of the high pressure action part 31 is larger than 30, the side plate 23 is pressed to a casing 24, and the valve unit 21 is pressed toward the side plate 23. A clearance determined by the thrust bearings 28, 29 is held in both sides of the valve unit 21, to obtain good controllability and high reliability. In the side plates 22, 23, since only a differential load between a pressure of a valve action high pressure part, pressing force transmitted from the thrust bearing and a pressure of the high pressure action part is only required to be supported by internal force, thickness is only required small to provide smallness in size and lightness in weight. Also manufacture is facilitated by eliminating necessity of aligning thickness or the like for ensuring the clearance in both sides of the valve unit.

CONSTITUTION:The magnetic head is composed of a magnetic substance 1, for which a void 2 of a prescribed interval is provided on the contact surface with the recording medium, a coil 3 to be wound in a part excepting for the contact surface of the magnetic substance 1 with the recording medium by a prescribed turn number and superconducting members 4a and 4b to be provided on the both side surfaces of the volid 2 besides the contact surface of the magnetic substance with the recording medium. Accordingly, a loop current is generated by the Meissner effect on the just superificial layer of a superconducting material to be set in an external magnetic field and this loop current generates a magnetic field so as to cancel the external magnetic field. Then, the magnetic flux in the superconducting material does not enter. Thus, the leaking magnetic flux is not generated in the side surface of the gap and upper oblique direction and the width of a recording track on the recording medium can be made equal with the track width of the magnetic head. Then, the signal output can be prevented from being lowered at the reproducing time.
