Patent JP-H06208899-A (JP)
Title: Ct scanner
Inventor: HACHIMAN MITSURU
IPC: A61B6/03
Filed: 1994-01-07
Abstract: PURPOSE:To cope with peak electric power during scanning even if a capacity of a commercial power source is remarkably reduced by disposing a secondary battery for performing supply of large electric power to a load in synchronism with supply of electric power to be supplied from the commercial power source. CONSTITUTION:A rectifier circuit 2 converts AC power of a commercial power source 1 into DC power. When a switch operation unit 4 interposed between the rectifier circuit 2 and a first unit 3 selects the side of the rectifier circuit 2, the DC power from the rectifier circuit 2 is supplied to a secondary battery 5. When the switch operation unit 4 selects the side of the first unit 3, an electric charge/discharge circuit is such constituted that power is supplied from the secondary battery 5 as an electric power supply source to the first unit 3. Furthermore, the DC power is supplied directly to a second unit 6 from the rectifier circuit 2. The side of the rectifier circuit 2 is selected during non- scanning by the switch operation unit 4 while the side of the first unit 3 is selected during scanning. The selections are performed in synchronism with timings of non-scanning and scanning operations of a controller.

Abstract: PURPOSE:To improve the efficiency of thawing work. CONSTITUTION:A holding vessel 20 of the apparatus is divided into four sections with three dividing members 22 having high-frequency wave shielding capability and the high-frequency wave energy is independently distributed into four divided sections 24. A food 26 can be placed on the lower face of the dividing member 22 and the holding vessel 20 by opening a door 21. Since each divided section makes a pair with each magnetron 28, four foods 26 are subjected to the similar high-frequency energy distribution to enable the completion of the thawing work at the same time.

Title: Switch circuit
Inventor: SHIOTANI JIHEI
IPC: H03M11/20
Filed: 1980-01-31
Abstract: PURPOSE:To provide a number of key switches with a limited number of signal lines, by installing several groups of switches formed into a matrix with a common use secured among the input signal lines for each switch group and then securing a parallel connection among the output signal lines via a reverse current blocking circuit. CONSTITUTION:It is supposed that the scan signals of different timings are sent to the input signal lines 1, 2 and 3. Then the key switch S22 of the switch group 20 is pushed. Thus the scan signal of the input signal line 2 is delivered only to the output signal line 5 among the output signal lines 4, 5 and 6. At the same time, only the output of the OR circuit 25 in the switch group identifying circuit 28 becomes ''1'' with push of the switch S22 of the group 20. As a result, the signal is sent only to the line 30 among the output signal lines 29, 30, 31 and 32 in the circuit 28. Then the outputs of the lines 29-32 are supplied to the encoder 33, and the output of the encoder is obtained through the output lines 11 and 12.

Title: Device for confirming weld bolt
Inventor: GOTO SHUJI
IPC: B23K11/14
Filed: 1992-01-27
Abstract: PURPOSE:To eliminate a dog adjustment by providing on the upper electrode an air passage that is opened at the lower end of the electrode, flowing air, detecting changes in air pressure and confirming the presence of a weld bolt. CONSTITUTION:The weld bolt 2 is welded onto a metal plate 1. The upper electrode 4 is lowered, and the metal plate 1 and the bolt 2 are held between the upper electrode 4 and the lower electrode 3 and pressurized. An air pressure is supplied from an air inlet 9 to the air passage 7, and the air pressure is detected by a pressure switch 10. If the bolt 2 is present, the air is blocked by the head part of the bolt 2, and the pressure is raised. If the bolt 2 is not present, the pressure is not raised. Thus, the presence of the bolt 2 is discriminated. A frequent adjustment is no longer required. Also, by flowing air in the state where the bolt 2 is not present, spatters accumulated in holes 5, 6 are easily cleaned.

IPC: H02M7/48
Filed: 1987-01-23
Abstract: PURPOSE:To inexpensively improve the efficiency of a voltage type inverter by switching the input/output of the inverter by a changeover switch connected to the input/output unit of the inverter according to the operating state of an AC motor. CONSTITUTION:An inverter is composed of a rectifier 2, a power inverter 3. and a smoothing condenser 5 provided in a DC voltage intermediate circuit, and further has a comparator 8, a power source side changeover switch 9 for switching the input/output of the inverter, and a motor side changeover switch 10.

When this voltage exceeds a specified voltage by a reference voltage generator 7, it becomes a regenerative state, and the comparator 8 outputs a regenerative side signal to both the switches 9, 10. Thus, both the switches 9, 10 are switched to switch the input/output of the inverter.

IPC: H01L21/683
Filed: 1994-02-04
Abstract: PURPOSE:To prevent necking on expansion by allowing a base film to consist of a plurality of layers and the layer at the surface side where no adhesive mass layer of the base film is provided to contain a friction-reduction agent. CONSTITUTION:A base film 3 of an adhesive tape 1 for fixing a semiconductor wafer consists of four layers (3a, 3b, 3c, and 3d) and a polymer of polyorefin and thermoplastic elastomer is used for each layer. A friction-reduction agent is contained in a base resin of the layer 3d in contact with a press tool at the opposite side of the adhesive mass coating layer 3a where the adhesive mass layer 2 is formed out of the layer constituting the base film 3. Then, no necking phenomenon for reducing the friction at the friction part between the adhesive tape 1 and the press tool occurs on expansion, thus fully and uniformly expanding the distance between chips and easily recognizing the image on pick-up and hence preventing malfunction.

Filed: 1978-02-06
Abstract: PURPOSE: To detect the position of an element accurately making use of the flatness between the enclosure provided to the circumference of the semiconductor element and its inside electrode.  
     CONSTITUTION: The output signal of line sensor 30 is differentiated 32 through LPF31. The output is compared 33 to 35 with +V th , zero and -V th  and comparison outputs 33 and 34 are delayed 36 and then added 38 to comparison output  35. Further, only signals changing from negative to positive is extracted 39 from  the differentiation output to obtain a flat part signal. At this time, the 1st enclosure  in the sensor scan direction has the flat part appearing next, and the rear enclosure  has that at the front. To extract the signal of the front enclosure, a zero- cross  signal (comparison output 34) is delayed 40 and added 41 to a flat signal. To obtain a rear-enclosure signal, the flat signal is delayed 41 and added 41 to the zero- cross signal. As for the direction perpendicular to this scan, a similar method is provided, so that the element position can be found accurately from both pieces of information.
