Title: Magnetic disk device
Inventor: MIYATA KEIZO
IPC: G11B17/038
Filed: 1999-10-27
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable magnetic disk device by securing the coincidence between the inner hole center and the rotational center of a magnetic disk to prevent the digital information signals recorded on the magnetic disk from having eccentricity to the rotational center of the magnetic disk when the magnetic disk where the digital information signals are previously recorded on the concentric circles set around the inner hole center of the magnetic disk is mounted on a spindle hub. SOLUTION: A taper 13 is formed on the outer circumference of a spindle hub 12 and in the direction of a rotational center axis 15. A magnetic disk 11 put on the hub 12 so as to make the inner hole end of the disk 11 touch the taper 13. Then a press-in ring 14 is fit to the hub 12 and the disk 11 is fixed to the hub 12, In such a constitution, the coincidence is secured between the inner hole center of the disk 11 and the axis 15.

Title: Semiconductor device and its manufacture
Inventor: FUKUZUMI YOSHIAKI
IPC: H01L23/485
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To prevent the risk of a short circuit, when wiring interval is reduced and realize a wiring structure satisfactory in embedding characteristic of a conducting material by forming a contact hole to a wiring trench in a self- aligned manner. SOLUTION: The thickness of a first insulating film 13 practically corresponds to the depth of a contact hole 18. The surface of a second insulating film 14 becomes the bottom surface of a wiring trench 17. The contact hole 18 has a taper angle practically only on a sidewall part 181 which intersects the direction of the wiring trench 17. This construction is achieved by a condition, where etching selection ratio of the second insulating film 14 and the first insulating film 13 is set to be somewhat low, and a part from which the hole edge of an aperture part 15 on the second insulating film 14 is exposed is etched slightly at the etching of the wiring trench 17.

Title: Ozone sensor
Inventor: TACHIBANA KOICHI
IPC: G01N27/12
Filed: 1994-11-14
Abstract: PURPOSE: To improve the stability of an ozone sensor with the lapse of time by adding a specified amount of bismuth to gas sensing body consisting of mainly In2 O3 . CONSTITUTION: A gas sensing body 2 is produced by applying a solution consisting of In2 O3 containing SnO2 as a main component and to which bismuth is added as an additive to the surface of an alumina substrate 1 of a thin film ozone sensor element 10. At that time, the addition amount of bismuth is set to be 3-15wt.% (in conversion into Bi2 O3 ) of the total weight of the In2 O3 and SnO2 . Furthermore, gold electrodes 3, 3', 7, 7' for the sensing body 2 and a heater 4 are formed in the substrate 1. Electricity is communicated continuously to the element 10 in air at 20 deg.C and 60% relative humidity and the element is taken out at every prescribed time to measure the resistance value of the element 10 in a measuring box and the sensitivity of the sensor is measured.  At that time, in the case the gas sensing body 2 contains bismuth 3-15wt.% (in conversion into Bi2 O3 ), the alteration with the lapse of time is low and the initial characteristics are stable. In this way the stability of the sensor with the lapse of time can be improved by limiting the addition amount of bismuth to be 3-15wt.%.

Title: Electrolyte for lead-acid battery
Inventor: TOSHIMA KAZUO
IPC: H01M10/08
Filed: 1994-12-09
Abstract: PURPOSE: To improve the discharging capacity of a lead-acid battery and extend the service life by designing the additive to the electrolyte. CONSTITUTION: This electrolyte is used for lead-acid battery, and a hydrogensulfide is added thereto. Since the hydrogensulfide has a high solubility to electrolyte, compared with a conventional sulfate, the effect for suppressing the generation of Pb<2+> , at an over discharge, to suppress the crystal growth of PbSO4 or the reduction in conductivity of the electrolyte is improved by the portion that the adding concentration to the electrolyte can be increased. The precipitation of the hydrogensulfide on a grid-active material critical surface under low temperature can be also suppressed to suppress the problem that the shielding between grid-active materials by the precipitated material.  Further, although PbSO4 repeats dissolution and precipitation to grow the crystal when the pH of the electrolyte is increased, the hydrogensulfide is advantageous for suppressing the crystal growth of PbSO4 because it has a high acidity, compared with the sulfate.

Abstract: PURPOSE:To improve certainty and reliability of control and to reduce the number of parts, a manufacturing cost, and the size of a device by a method wherein input ports from a liquid temperature detector and a liquid temperature setter are selected by a microcomputer, and based on an input electric signal, a difference between a liquid temperature and a cooling temperature is digitally computed, and a control signal by means of which the difference is reduced to zero is outputted to a liquid cooler. CONSTITUTION:A control part 13 of a microcomputer 2 decides whether a mode change-over switch 4 is changed over to either control of an oil temperature absolute value or tuning control of a room temperature. When it is changed over to the former, by adding a set value VR1 of an oil temperature setter 8 and a regulation value VR3 of a regulator 10, a set temperature is determined. Meanwhile, if it is changed over to the latter, by adding a detecting value from a room temperature detector 7, a set value VR2 of a temperature difference setter 9, and a regulation value VR3 of the regulator 10, from an oil temperature represented by means of a detecting signal from an oil temperature detector 6, a set temperature is computed to determine a difference. By means of the difference, a control signal, by means of which a refrigerant compressor 3b is turned ON or OFF, is outputted to an oil cooler 3 through an output part 14. This constitution enables the reduction of the number of contact parts as compared with a conventional analogue control device.

Title: Loop back releasing system
Inventor: FUJISAWA TAKANORI
IPC: H04B10/29
Filed: 1988-12-06
Abstract: PURPOSE:To speedily release a closed loop generated between optical repeaters by detecting a high level state which continues longer than the prescribed time of an optical signal supplied to a photoelectric conversion part and releasing the generation state of a loop back path. CONSTITUTION:A loop back command is given to an O/E conversion part 5 as an optical signal (d) without releasing the loop back path (b) by misoperation, and a loop back path (c) is generated between an E/O conversion part 4 and the O/E conversion part 5. When the optical signal (a) of an 'H' level is continuously given to the O/E conversion part 1 in such a case, the output of an identification reproduction circuit 3 goes to the 'H' level through the O/E conversion part 1 and an equivalent amplifier circuit 2. Then, a timer action in a timer circuit 10 starts. When the 'H' level state of the output of the identification reproduction circuit 3 continues longer than a previously set time, a control pulse signal is transmitted and a command reception part 9 transmits the control signal to an E/O conversion part 8. Thus, the generation state of the loop back part (b) is released and it can get out of the closed loop state.

Title: Molding machine
Inventor: KURODA MASAAKI
IPC: B29C45/73
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To avoid a molding fault of a molding by covering a periphery of a cavity to be filled with a molding raw material with a magnetic coating layer through a heat insulator layer, selectively heating a first surface of a specific site of the outer periphery of the molding by an electromagnetic induction, and generating a temperature difference to an adjacent second surface. SOLUTION: A molten molding material of a predetermined amount is filled in a cavity 14 under a predetermined pressure through a spool 20 and a gate 15. High frequency induction coils 8A, 8B are conducted to heat coating layers 12, 22 to a glass transition point or above to prevent solidification of resin at the time of feeding a lens material by cooling, thereby avoiding a weld line and a shrinkage. A fixed side mold 4, a movable side mold 16 and dies 6, 18 are heat insulated by a heat insulator layer 10, and hence not heated so that a temperature difference is generated in a molding cycle between the layers 12, 22 and the other sides of the mold 4 as the second surface and the mold 16. Thus, even when the layers 12, 22 of inner wall surfaces for forming the cavity 14 of the mold are formed of an aspheric cuttable material and thickness, a molding fault of the molding can be avoided.
