Title: Thermal adhesive conducting paste for fitting ic chip
Inventor: HAYASHI OSAMI
IPC: H01B1/20
Filed: 1988-07-28
Abstract: PURPOSE:To eliminate the defective insulation between adjacent electrodes and lower the connection resistance by constituting the conducting paste with a base resin solution solved with adhesive heat-melted resin in a solvent, conductivity applying powder and specific spacer grains. CONSTITUTION:A conducting paste is constituted of a base resin solution solved with adhesive heat-melted resin in a solvent, conductivity applying powder, and spacer grains 6 having the softening point higher than that of the base resin end the grain size larger than that of the conductivity applying powder and the grain size dispersion of + or -2mum or below. When this conducting paste is used to directly fit IC chips to a glass board via conducting resin bumps to form conducting resin bumps on input/output electrodes, the conducting resin bumps do not flow out from electrode sections even if the excessive pressure is applied. The defective insulation between adjacent electrodes due to the outflow of bumps is not generated, the connection resistance is lowered.

IPC: H01H9/54
Filed: 1994-07-18
Abstract: PURPOSE:To make it possible to detect failures easily by installing a state memory means having a man-volatile memory which starts detection data detected with a state detection means even when a sanitary device receives no power supply. CONSTITUTION:When a user sits on a closet seat and depresses a hip flushing pushbutton switch 13a, for example, a signal is outputted to an input processing circuit 10a of an electronic control device 100 from a sit-on seat sensor 15a and an operation pushbutton switch 13A. The signal is outputted from an output processing circuit 109 to a first on/off valve 37a so that the valve may be opened so as eject flushing water from a nozzle device. When a sit-on seat counter exceeds a specified time, a failure state determination flag of the sit-on seat sensor 15a is set so that such operations as flushing may be halted and the failure determination flag thus set is stored in a back-up RAM 107. When the sit-on seat time exceeds a setting sitting time, it is determined as a failure of the sitting sensor 15a due to this construction and used as data for detecting failuie when molding.

Title: Divided main reflection mirror for antenna equipment
Inventor: INO TOSHIO
IPC: H01Q15/16
Filed: 1992-07-16
Abstract: PURPOSE:To considerably reduce the junction work requiring the large man-hour in a conventional device by eliminating slits of a reinforcing member in the peripheral direction of a reflection mirror plate. CONSTITUTION:A divided main reflection mirror 7 is provided with a reflection plate 8 and reinforcing members 9 and 10 which are constituted on the rear face of the reflection plate 8 to not only hold the mirror surface precision but also holding the strength and the rigidity, and they are joined by rivets 12. Since the reinforcing member 10 in the peripheral direction of the divided main reflection mirror 7 has short constitution length and is a part of a large elliptic curve 4, the error is very small even if it is approximated to a circular curve. Therefore, the precision is secured even when it is approximated to a circular curve, and the reinforcing member 10 in the peripheral direction is not provided with slits 11 and is formed into a roll. As the result, the number of rivets 12 for junction between the reflection plate 8 and the reinforcing member 10 in the peripheral direction is considerably reduced in comparison with junction between the reflection plate 8 and the reinforcing member 9 having slits 11 in the radial direction, and the labor of junction work is reduced.

Title: Refrigerator
Inventor: YAMADA KOJI
IPC: F25D11/00
Filed: 1987-07-29
Abstract: PURPOSE: To enable the operation of a refrigerator to be started again under a cooling operation state corresponding to a power failure recovering time by a method wherein there is provided a battery back-up circuit for applying a control power supply of a battery against a clock circuit when the power failure occurs. CONSTITUTION: In case that a power failure occurs, a control power supply of a battery 22 in a battery back-up circuit 19 is given to a clock circuit 13. Accordingly, the clock circuit 13 keeps a time counting operation while its function is being continued. However, since an output of a power-down sensing circuit 23 becomes a low level, no transfer of data is carried out between the circuit and a micro-computer 17. As the power failure is recovered, an output of the power-down sensing circuit 23 becomes a high level and the clock circuit 13 gives a time correcting data to the micro-computer 17.  As a result, the microcomputer 17 corrects an internal time data in response to an output data attained from the clock circuit 13, detects a control time band in response to the internal time data and starts the operation again under a cooling operation state corresponding to the time band at this time.

CONSTITUTION:The resist 12 which has the min. value of the developing rate with respect to an exposing intensity when baked at 110 to 120 deg.C prior to exposing is applied on the substrate 1 and is baked at 110 to 120 deg.C. The translucent mask 13 is then disposed on a part of the resist 12 and the resist 12 is exposed by the two-beam interference exposing method at the exposing intensity at which the max. value and min. value of the exposing intensity at the points not coated with the translucent mask 13 are on both sides of the intensity to minimize the developing rate and the max. value of the exposing intensity is below the intensity to minimuze the developing rate at the points covered with the translucent mask 13. The resist 12 is thereafter developed and is patterned to the diffraction grating 23a. The substrate is etched with this pattern as a mask, by which the diffraction grating 23b is formed.

IPC: H04N19/00
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a multiplex coding device by which different image quality is designated for each channel. SOLUTION: A mean value of reference deviation signals outputted respectively from subtractors 121 -12N is calculated by a mean value calculation device 16 and the result is fed in common to substractors 141 -14N as the mean deviation signal. The subtractors 141 -14N subtract the mean deviation signal out of each reference deviation signal by each channel from the subtractors 121 -12N corresponding to the subtractors 141 -14N, so as to calculate an increment/decrement value denoting the degree of deviation of the channel in comparison with the mean dissociation of all channels, and to provide an output to compression rate control sections 151 -15N.  The compression rate control sections 151 -15N generate a compression rate control signal for each channel independently of each other, and output the result to coding processing sections 111 -11N to increase the compression rate when the incremented/decremented value is positive, and to decrease the compression rate when the incremented/decremented value is negative.

And a violent reaction in the secondary treatment can be completely controlled. The Cd reacts completely with the Se in the secondary treatment, and the CdSe contg. no unreacted matter can be obtained.
