Patent JP-S61147117-A (JP)
Title: Earthquake sensor with sensitivity correction
Inventor: KO HIROSHI
IPC: G01H9/00
Filed: 1984-12-20
Abstract: PURPOSE:To achieve earthquake sensing immune to an environmental change or secular change by providing a photodetecting element, which receives light from the inside of a container filled with liquid and converts it into an electrical signal, and a signal processing part and a sensitivity correction device. CONSTITUTION:When the container 31 is in a still state, the distribution of luminance inside the container 31 is constant, and the output signal 20a of the photodetecting element 35 is composed only of a constant DC voltage. When the liquid contained inside the container fluctuates, however, due to a quake, the form of a liquid surface changes, and the distribution of the luminance changes, thereby changing the signal 20a of the element 35. A DC component Va may be in danger of erroneously detected in a method which connects an electric power source 33 directly to a light emitting element 34, in this case. Since an electric current control part 44 controls a current flowing into the element 34 in a manner that a DC component 41a of the element 35 coincides always with a constant voltage command 42a ordered by a reference voltage device 42, an output signal 22'a of an AC amplifier 22' becomes always the same signal as far as the earthquake quakes at the same acceleration. Accordingly, the identification and the processing of a P wave at an initial stage of the earthquake and an S wave of the main earthquake are made possible, thereby achieving accurate earthquake sensing.

Title: Autonomous inverter driving hydraulic unit
Inventor: HORIUCHI HITOSHI
IPC: F04D15/00
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To autonomously control the pressure and the flow without using an input signal line while eliminating the necessity of inputting the command pressure and the command flow from outside. SOLUTION: A target horsepower computing unit 25 of a controller 11 discriminates in which area (a), (b), (c) a point expressing the real operating condition (real pressure, real flow) exists, and computes the target horsepower to be expressed with a point on a target pressure-flow characteristic line on the basis of the real pressure and the real flow. A comparing unit 28 obtains a deviation between the target horsepower and the real horsepower received from a real horsepower computing unit 26, and inputs the control signal showing this deviation to an inverter 3, and controls the number of revolution of a variable speed motor 2 so that the real horsepower coincides with the target horsepower. Autonomous control is performed so that the real pressure and the real flow exist on the target pressure-flow characteristic line.  An input signal line becomes unnecessary, and the wiring in the surroundings is simplified.

Abstract: PURPOSE: To provide a microelectronic circuit package which is capable of being reworked and its reworking method. CONSTITUTION: A circuit package 1 capable of reworking is formed by a chip connection (C4) system, which connects an integrated circuit chip 21 with a circuit card and a circuit board and controls solder breakdown, and a direct chip attaching(DCA) system which deposites a sealing material under the chip 21. The sealing material protects connection parts by the C4 system and provides a coefficient of thermal expansion conformal with that of the junction part by the C4 system. In the case of nearly completely sealing material, the package 1 cannot be reworked. The circuit package 1 can be reworked, and the problem is solved by preparing a parylene active layer, wherein a treatment is possible by a dry system, and uniform deposition is enabled by vapor deposition.  Hence a thin film is formed on the surface of a film of 3-5μm thickness, which corresponds to an air-gap distance formed by the chip-connection C4 system controlling the solder breakdown.

Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To reproduce a black character with high quality by preventing void around the black character in a color background in the case of reducing the resolution of an attribute signal. SOLUTION: In an area where an image area signal AS is at '1' by an image area separate circuit 75, that is, the signal is identified to be a character part a filter 77 applies image processing as a coefficient having a characteristic of edge emphasis. Furthermore, when the black color signal BS in the area identified to be a character part is identified to be '1', that is, single black color, a decode circuit 82 sets a decode signal DS forcibly to '0 (pattern part)'. Thus, in the case of the black part in the character part, low line number processing and smooth gamma processing are applied to a background color other than the character similarly to the processing of the area of the pattern part to prevent void at the circumferential part of the black character.
