Inventor: MIYOSHI MASAYOSHI
IPC: H01L21/60
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To enable realization of mounting structure of an LSI chip where the strength of a connecting part of the LSI chip can be sufficiently obtained, when solder bumps are made minute in accordance with high level integration of a semiconductor integrated circuit, and flux used in the course of soldering can be eliminated by cleaning. SOLUTION: A plurality of soldering pads 5a for a power supply or ground which are formed on one surface of an LSI chip 2 are connected with soldering pads 4a formed on one surface of a substrate 1, via solder bumps 6a. A plurality of soldering pads 5b for signal, which are formed on the one surface of the LSI chip 2, are connected with soldering pads 4b formed on the one surface of the substrate 1 via solder bumps 6b. Since the size of the solder bump 6a is made larger than that of the solder bump 6b, strength can be sufficiently obtained when the solder bump 6b is made minute, and a gap between the LSI chip 2 and the substrate 1 can be ensured.

Inventor: YAMADA HIROSHI
IPC: G11B5/027
Filed: 1986-06-13
Abstract: PURPOSE:To completely eliminate the switching operation of a manual switch by automatically discriminating by which mode among plural modes recording is executed based on a reproducing video signal. CONSTITUTION:When an input reproducing luminance signal is recorded in the standard mode by the selection of the pass band characteristic of BPFs 2 and 3, the output signal of the BPF2 is taken out in a larger amplitude than the BPF3 and when it is recorded in the high picture quality mode, the output signal of the BPF3 has the larger amplitude than the BPF2. Respective envelope detecting signals taken out from LPFs 6, 7 are respectively supplied to a comparator 8 where levels are compared. Namely, the comparator 8 compares in level the envelope levels of the carrier frequency components of the two modes obtained from the reproduced FM luminance signal, thereby, a mode discriminating signal indicating a first logical level when the reproduced FM luminance signal is recorded in the standard mode and a mode discriminating signal of a second logical level when it is recorded in the high picture quality mode are generated and outputted to an output terminal 9.

Title: Measuring device for directivity of antenna
Inventor: MIKUNI YOSHIHIKO
IPC: G01R29/10
Filed: 1980-09-30
Abstract: PURPOSE:To realize the measurement with high accuracy for the electric field near an antenna without giving any effect to the line at a mobile part, by compensating the value measured by a probe based on the measured value of the reference intermediate frequency signal which is reflected from an interruption switch. CONSTITUTION:When a breaker 16 is turned off, the reference intermediate frequenxy signal given from an oscillator 8 is reflected by the switch 16 to be extracted via a two-way coupler 15. Then the amplitude and the phase according to the loss of a line 13 or the change of the electric length, etc. are detected by an amplitude/ phase detector 20. Afterward, the breaker 16 is turned on, and the amplitude and the phase of the electric field of an antenna 1 which are converted into the intermediate frequency signal by a mixer 6 and caused by a probe 5 are detected by the 1st amplitude/phase detector 11. The value fo this detection is compensated by an operator 12 basing on the detection value of the detector 20. Accordingly the electric field distribution near an antenna is measured with high accuracy and without giving any effect to the change, etc. of the line at a mobile part. Thus the antenna directional pattern is accurately decided.

Filed: 1987-05-30
Abstract: PURPOSE:To speedily and securely replace a filter by providing an interlocking means which is fixed to an endless belt correspondingly to respective filter positions and moves a prescribed color filter to an optical path of image formation against a spring means when the belt is rotated. CONSTITUTION:A driving projection 50 fixed on the endless belt 48 moves a filter frame 34 into the optical path of an image formation optical system 16 first. Then when the driving projection 50 moves to nearby right above a roller 46, the endless belt 48 stops and an original is scanned in the state. Then a rotary driving system 49 drives the endless belt 48 again and the driving projection 50 which engages an interlocking projection 35 so far moves to the reverse surface of the roller 46, so the filter frame 34 moves away from the optical path instantaneously with the force of a spiral spring 43. At the same time, the 2nd driving projection 50 from the left engages the interlocking projection 35 of B and similar operation is repeated thereafter. Consequently, the filter replacement is speedily and securely carried out.

Title: Lighting jig for inspecting reflective liquid crystal display panel and inspecting device
Inventor: SHIMIZU MASAHIRO
IPC: G01N21/84
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To provide an inspecting device for inspecting defective display of a reflective liquid crystal display panel provided with a reflection electrode. SOLUTION: On a front surface side of a reflective liquid crystal display panel 1, a light source 18 for projecting light is provided.
