Title: Semiconductor device
Inventor: KOJIMA MICHIAKI
IPC: H01L23/64
Filed: 1984-06-18
Abstract: PURPOSE:To obtain the stable titled device of wide operating margin by reducing the amount of noise by a method wherein the inductance of a reference potential is reduced by shortening the inner lead frame of the reference potential terminal and the enlarging its area. CONSTITUTION:The inner lead frame 4 of a reference potential is set at 1:1 or less in length to the lead frame 3 on the diagonal line and at 1:1 or more in the ratio of area by moving the center point of a cavity 2 from the center point of the package toward the reference potential terminal. This construction enables the noise generating at the reference potential by the capacitance coupling of the internal operating contact with the substrate 1 during the operation of the internal circuit to be reduced by a factor of a reduction in resistance L of the reference potential according to a formula dV=L.di/dt; therefore, the device of high stability whose input level, output level, and internal circuit operating margin have been enlarged can be obtained.

Title: Removing device for ascending jointing noise in bidirectional catv system
Inventor: OUE YUJI
IPC: H04N7/173
Filed: 1988-05-23
Abstract: PURPOSE:To remove an ascending jointing noise by specifying the frequency band of an ascending signal, which exists in a branch to be connected to a branching point, by a signal detector and controlling a filter so that only the ascending signal of the frequency band can be transmitted to a trunk line. CONSTITUTION:An ascending channel is divided into the four frequencies of f0, f1, f2 and f3 and used with frequency-multiplexing. A signal detector 112 supervises that a signal exists in which frequency of the f0 to f4 concerning a branch 120. A filter 111 controls the signals of the frequencies f0 to f4 are individually passed to the trunk line or blocked and controls the signals by the detector 112. Only the frequency band, in which the ascending signal exists in the branch 120, is passed to the trunk line. Accordingly, even when the noise exists in the branches 120 and 121, the noise does not flow into the trunk line. Thus, the ascending jointing noise, for which the noise from the branch is overlapped on the trunk line, is removed.

Filed: 1988-05-23
Abstract: PURPOSE:To reduce the size of the device and to reduce the time and labor for the adjustment of an optical system by discriminating a Doppler beat signal according to laser output light which is used when the speed of the moving body is measured. CONSTITUTION:The Doppler beat signal outputted by a beat detecting means 1 is amplified (signal 1') by a rate level controller ALC7. Then a differentiating circuit 8 differentiates the signal 1' (signal 2') so as to compare the time of the rising slope of a saw-tooth wave with the time of the falling slope. This signal 2' is compared by a comparing circuit 9A with a reference level REF and then a rectangular wave (signal 3') which becomes high in level while the signal 1' has the rising slope is obtained. Similarly, the inversion of the signal 2' is compared by the other comparing circuit 9B with the REF and then a rectangular wave (signal 4) which becomes high while the signal has the falling slope is obtained. Then, signals 5' and 6' passed through LPFs 5A and 5B are compared by a comparator 6 to discriminate the moving direction.

Title: Method for measuring moisture content of ground fish meat and detection device by said method
Inventor: SATO MINORU
IPC: G01N27/02
Filed: 1989-05-19
Abstract: PURPOSE:To easily measure moisture content at the time of a manufacturing process by measuring a value of impedance being the function of salt concn. and measuring temp. or a value of the real number part thereof and calculating the salt concn. from said value. CONSTITUTION:As factors making the measured value of impedance (real number part) irregular, there are a function (a) of the temp. possessed by the physical properties of ground fish meat, a function (b) of the salt concn. (salt/ contained water) of ground fish meat and a function (c) composed of the salt/ protein wt. ratio related to the carrier movement in ground fish meat. Since protein in (c) can be present only in raw material ground fish meat, the wt. of protein present in processed ground fish meat can be specified from the ratio of protein in the raw material ground fish meat and a salt/protein wt. ratio can be handled as a constant by knowing the wt. of added salt. Therefore, the impedance (real number part) can be handled as the function of (b) and (a). Then, moisture content is calculated on-line and can be fed back to a process by knowing a relative value.

Title: Jig for heat-treating semiconductor
Inventor: MINAGAWA KAZUHIRO
IPC: B65D85/86
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To eliminate the occurrence of stress concentration to or cracking in a wafer by eliminating the need of forming grooves on a plurality of supports which connect a roof plate to a bottom plate by supporting the wafer by projections by horizontally attaching the projections to the supports at prescribed intervals in the length direction of the supports. SOLUTION: Projections 11 are horizontally attached to supports 12 which connect a roof plate 13 to a bottom plate 14 and have square cross sections at prescribed intervals in the length direction of the supports 12. The projections 11 can be formed to have elliptic cross sections, square cross sections, etc., as well as circular cross sections, but when bars having elliptic cross sections are used as the projections 11, the stress concentration acting on a wafer 2 can be relieved, because the curvatures of the wafer mount parts of the projections 11 become larger as compared with the case where round bars are used as the projections 11. In addition, since the attaching intervals of the projections 11 can be reduced as compared with the case where round bars having the same curvature are used, more wafers 2 can be places on the projections 11.
