Title: Performance deterioration detecting device for power unit
Inventor: ANDO TAKAHIKO
IPC: G01R31/00
Filed: 1988-01-18
Abstract: PURPOSE:To detect the deterioration of a smoothing electrolytic capacitor by measuring the holding time of an output voltage after an input power source is turned off by paying attention to the fact that the electrostatic capacity of the smoothing capacitor is proportional to discharge energy to the power unit after the input power unit is turned off. CONSTITUTION:When an AC power source for measurement is turned off, the output signals of voltage comparators 15 and 16 reach an H level and an L level respectively. Consequently, an H-level output signal from an RS-FF 17 is inputted to an integration circuit 18 permanently and then the output signal of a voltage comparator 22 is inverted from the H level to the L level a constant time tau after the input power source is turned off. This constant time tauis prescribed as a reference time. A D-FF 23 decides that the power source is normal when the tie for which the power unit holds the DC output voltage from the input power source for the power unit to be measured is turned off is longer than the reference time tau, but deteriorates when shorter.

Title: Vehicular stabilizer
Inventor: YAMADA SHIGEYUKI
IPC: B60G21/073
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To secure a vehicular stabilizer which effectively controls a vehicular roll, and also to prevent needless damping force from occurring when both lateral wheels are stroked in the same direction. SOLUTION: A pressure regulating cylinder 8 to be equipped with both first and second oil chambers 15, 16 and a gas chamber 13 being connected to each via two oil passages 9L and 9R, is installed in two hydraulic cylinder 7L and 7R installed in corresponding to both lateral wheels, while a free piston 12 to partition off the inside of this pressure regulating cylinder into the said three chambers, is slidably installed therein. As an orifice 14 communicating to both chambers is formed in a piston 12B partitioning off the first oil chamber 15 and the second oil chamber 16 of this free piston, in the case where these lateral wheels are stroked in the same direction, a working fluid is not passed through this orifice 14, so damping force is not produced at all.  In time of a roll when both lateral wheels are stroked in the reverse direction, since quantities of the working fluid running inflow or outflow in or from both the first and second oil chambers 15 and 16 are varied to some extent, therefore the working oil comes to pass through the orifice 14 in consequence and thereby the damping force is produced, so that this damping force to any motion in a roll direction of a car body is increasable, and thus the roll is controllable.

Title: Magnetic tape taking up device
Inventor: GOTOU SADAICHIROU
IPC: G11B23/113
Filed: 1995-01-20
Abstract: PURPOSE: To discharge air via circumferential grooves at the time of traveling at a high speed so as to prevent the formation of an air film between a magnetic tape and a guide roller by forming these grooves on this roller. CONSTITUTION: Both side faces of the guide roller 5 near a tape cassette are provided with flanges 5a for regulating the tape and the spacing between these flanges 5a is set larger than the width of the magnetic tape. The roller 5 is provided with four pieces of the grooves 10 and the length 1 between both ends thereof is set larger than half the tape width. As a result, the air is discharged through the grooves 10 and the air film is no more formed between the roller 5 and the tape even if the tape travels at a high speed. Then, the stable traveling of the tape is made possible and the regulated winding of the tape on the reel of the tape cassette is assured. The number of the grooves 10 suffice with >=3 pieces.

Filed: 1989-01-18
Abstract: PURPOSE:To improve checking efficiency by comparing the length of a part where the width of a pattern continues to be wrong with a set reference value thereby to detect whether the wrong part is allowable for a product. CONSTITUTION:The width of a lead pattern at right angles in an elongated direction of the pattern is detected while the elongated direction is determined. If a signal T1 indicating that the pattern width is larger than the maximum predetermined value is output, the part having the abnormal pattern width is extracted from the normal part and a pattern signal of the abnormal part is moved to a different image memory 41. The length of the abnormal part in each direction is measured by a measuring sensor 42 in a measuring circuit based on information related to the pattern of the abnormal part in the memory 41 and the elongated direction of the abnormal part is selected by an elongated direction selecting circuit 44. So long as the length of the abnormal part continues, the information is integrated and the length of the abnormal part in the elongated direction is added in an adder circuit 45. In a comparison circuit 46, the output of the circuit 45 is compared with a reference value in a decision circuit 47 for decision of the abnormal part, so that it is decided whether the abnormal part is allowable for a product.

IPC: F25D11/00
Filed: 1995-01-23
Abstract: PURPOSE: To provide an electronic refrigerating type refrigerator which is improved to allow cold insulation over the entire area in a storage evenly. CONSTITUTION: This electronic refrigerating type refrigerator employs a thermomodule 4 of a thermoelectric cooling element for a cooling unit 3. The thermomodule is incorporated into a rear wall surface of a cabinet 1 and a heat absorbing body 6 with a fin coupled to transfer heat is set vertically on a heat absorbing surface of the thermomodule sticking out to the inside of the storage while a dew tray 9 is arranged below the heat absorbing body. In such an arrangement, the lower rim of a fin part 6b of the above heat absorbing body is cut aslant so as to be lower toward a substrate part 6a on the root side from the front end thereof. The depth range (d) facing the lowest end part is fixed to the minimum dimension smaller than the sticking height H of the fin of the heat absorbing body with the fin but enough to cover the substrate part.  Thus, the dew tray little blocks thermal convection of the chilled air in the storage while allowing the recovering of the total amount of drain water dripping during the defrosting.

Title: Optical switch
Inventor: SAKAI KAZUO
IPC: G02F1/015
Filed: 1987-01-19
Abstract: PURPOSE:To enable an optical switch to respond fast by injecting only electrons by utilizing a triangular barrier of n-i-p-i-n structure. CONSTITUTION:A switch part S is formed of (n) (substrate 11), (i) (1st superlattice layer), (p) (p-type semiconductor layer), (i) (2nd superlattice layer), and (n) (layer 14). Further, the layer thickness and impurity concn. of the i-p-i layer is so determined that a waveguide layer 12 (i-p-i) is made into a depletion layer while external energy such as an applied voltage is not applied to the switch part S (thermal equilibrium state). Consequently, only many carriers (electron) contribute to a current at the time of voltage application a small number of carriers (positive holes) do not contribute the current, increasing the response speed. Namely, when the i-p-i layer of the n-i-p-i-n structure is made into the depletion layer, there are only electrons of both n layers (11 and 14) even by the voltage application, so only many carriers contribute the current. Consequently, a high-speed response is made with small size and a low voltage.
