Title: Magnetic shield for color picture tube
Inventor: YOSHIHARA YOSHIO
IPC: H01J29/06
Filed: 1982-05-14
Abstract: PURPOSE:To enable a single specification of phosphor screen to be available for all regions on the earth by using a number of materials that differ in holding points in magnetic hysteresis characteristics as the shielding materials and magnetizing a desired magnetic field at the side provided with the higher holding points than those of a demagnetizing field. CONSTITUTION:A permanent magnetic field that optimizes color ununiformity under the geomagnetic conditions of a desired region using a magnetic field generator 5, is set by incorporating a magnetic shield 1 with the hysteresis characteristics of holding power H1 and a magnetic shield 2 with the hysteresis characteristics of a holding point H2 in a picture tube. As a result, a color picture tube with few deterioration of color ununiformity that can be available over all regions having different configuration of geomagnetism with the same specification of phosphor screen can be obtained.

Title: Method for tracking servo
Inventor: KUBO JUNICHI
IPC: G11B7/085
Filed: 1989-03-30
Abstract: PURPOSE:To stably pull in a spot to an objective track in a very short time by closing a tracking servo loop when it is detected that relative speed is zero while it is detected that the spot being accelerated toward the objective track is positioned within prescribed distance. CONSTITUTION:An AD converter 1 converts a tracking error signal into a digital signal, and sends it to a servo processor 2. Then, the processor 2 executes tracking servo processing. Then, when the spot is going to get out of the objective track, it makes the spot go toward the objective track. Besides, when the spot is going toward the objective track, it adjusts the relative speed with the spot so as to be a proper value. Further, when the spot is positioned in the vicinity of the objective track, and the relative speed between the objective track and the spot is sufficiently small, it closes the tracking loop. Thus, the spot can be pulled in to the objective track quickly and stably.

Title: Nozzle for gas wiping
Inventor: HAMADA HIDEKI
IPC: B05C11/06
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To maintain a good wiping action even when a gas pressure is lowered by arranging an angle adjustment plate or an angle adjustment block enlarging an inclining angle of a nozzle front end face at least to a lower side front inclined face of a nozzle main body. SOLUTION: An opening angle of an angle adjustment plate 20 is added to an inclined angle of a front end inclined face of a nozzle main body 10, and a substantial angle of a nozzle front end face is changed. The gas flow injected from a nozzle mouth, after colliding with a steel strip 1, is made an ascending flow a and a descending flow a1 , and the descending flow a2 is deflected at a molten surface 8 of a hot dip bath 4 to be turned to a horizontal flow a3 . Part of the horizontal flow a3 generates an eddy flow a4 , as a result, a static pressure of a center part on an extension line on the nozzle mouth 16 is decreased to lower a peak of a total pressure, and thereby a hot dip galvanized metal to be removed from the steel strip 1 is decreased.  Further, the descending flow a2 , in which a flow speed is increased by the eddy flow a4 , positively pushes back the dross, etc. stuck on the steel strip 1 to the hot dip galvanizing bath 4, and thus a foreign matter brought to a hot dip galvanizing layer is reduced.

Title: Switch device
Inventor: NAKAMURA SHIGEO
IPC: H01H15/06
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a switch device which can ensure good insulating performance between stationary contacts without enlarging the device as a whole. SOLUTION: When movable contacts 17 and 18 slide on the oversurface 13a of a base 13, stationary contacts 19a, 19b, 19c and 20a, 20b, 20c are connected together electrically. Because wiping mechanisms 22 and 23 are made of a elastic material, their sliding parts 28-31 slide intersecting the sliding loci of the movable contacts 17 and 18 in compliance with their sliding motions. Therefore, arcs are produced by the switching operations, and eventually deposited carbides on the sliding loci of the movable contacts 17 and 18 will be removed from upon the sliding loci by the sliding parts 28-31.

Title: Clutch operating device with hydraulic booster
Inventor: IDETA YASUFUMI
IPC: F16D48/04
Filed: 1981-05-29
Abstract: PURPOSE:To prevent a clutch from slipping, by using a spring to energize the power piston of a hydraulic booster toward a withdrawal lever so that no clearance is made betweeh the clutch and the power piston. CONSTITUTION:A lid 71 is mounted in the entrance part of the piston hole 42a of a booster body 42. A seal 72 is provided between the lid 71 and the piston hole 42a so that the seal and the lid are tightened as to the piston hole. Another seal 73 is provided between the lid 71 and a push rod 68 extending through the lid, so that they are sealed up. Since a power piston which slides in the booster body 42 is always energized by a spring in such a direction as to operate a withdrawal lever 31 by low force, no clearance is made between the operating lines of a clutch and the power piston. As aresult, the position of a clutch disc is shifted depending on its wear and the clutch is prevented from slipping.

Title: Stop of oscillation detection circuit
Inventor: YAMAZAKI TAKU
IPC: H03K5/19
Filed: 1989-03-31
Abstract: PURPOSE:To reduce a consumption current by setting a capacitor and a resistance which are connected in parallel between a node and a power potential to be small capacitor and the high resistance in a circuit which judges whether a signal to be operated at a prescribed period is operated or not and which detects the stop of oscillation. CONSTITUTION:CL is an alternation signal at the prescribed period, and an inverter 11 obtains a negative phase signal, whereby transistors Tr111 and Tr212 are prevented from simultaneously being turned on and off. When CL repeats high and low, the potentials of points P1 and P2 approach VDD. When a time constant C2.R2 is set longer than the period of CL, an oscillation stop detection signal Fst becomes low. When oscillation stops, either of the transistors Tr1 and Tr2 is turned off without fail, charge for the capacitor C2 is eliminated, a point P2 comes to the low level by the high resistance R2, and Fst becomes high. If the value of the high resistance R2 is sufficiently enlarged, the value of C1 can be small. Since C1=1-2pF can be assumed by using a non-doped polysilicon having a value more than 10 deg.OMEGA for the high resistance, it can be placed on an IC chip, and the consumption current can be reduced.

Abstract: PROBLEM TO BE SOLVED: To determine the distance to an object uniquely in a short time using a small scale of circuit by obtaining a distance signal from an output ratio signal according to a conversion formula dependent on a reference value (threshold value) for deciding whether a clamp operation is present or not under standard conditions.

An operating circuit 14 and an integrating circuit 15 receiving a proximal signal 11 from the PSD 5 and the signal I2c from the clamp circuit 13, respectively, determine the output ratio (I1/(I1+I2c)) and a CPU 1 determines a distance signal according to first or second conversion formula depending on a threshold value for determining the presence of clamp operation. The second conversion formula is determined based on the first conversion formula.

Title: Magnetic head device for flexible disk
Inventor: ANAZAWA SHIZUO
IPC: G11B5/60
Filed: 1985-04-17
Abstract: PURPOSE:To improve the strength of attachment between an elastic bar and a magnetic shielding plate and to perform the attachment of the shielding plate in an accurate and easy way, by extending an extension part for attachment of shielding plate having a contact with the elastic bar formed with flection at the outside to a part of the open end part of the masking plate. CONSTITUTION:A magnetic shielding plate 11 is formed into a frame shape as a whole and prevents the mixture of a magnetic field from outside. While two extension parts 12 and 12 for attachment of the plate 11 are extended in a body to a part of the open end part of the plate 11 to secure a contact with an elastic bar 1 formed with flection at the outside. Thus a gap 13 is formed between the plate 11 and the bar 1 by an amount equal to the thickness and the bending margin of the plate 11. Therefore the plate 11 can be attached accurately to the bar 1 despite an adhesive swelled out. Furthermore the area for attachment can be increased between the bar 1 and the plate 11 since the parts 12 are set opposite to the bar 11. This increases greatly the strength of attachment between the bar 1 and the plate 11.
