Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To specify the cause of an alarm. SOLUTION: An output judgement part 11 informs an annunciator 8 that an alarm is generated in such a case and stores an index specifying the generation of the alarm to a corresponding alarm generation factor in a factor and output destination management data base 12.

Title: Radio repeating device
Inventor: SAITOU KUNIO
IPC: H04B7/155
Filed: 1980-09-22
Abstract: PURPOSE:To eliminate the need to operate a transmitter and a receiver simultaneously by storing received communication information in a storage part temporaily and by sending the stored information from the transmitter on reception. CONSTITUTION:If a transmitter-receiver 31 receives a radio wave having continuation time equivalent to a frequency f1 at which it is expected to operate as a repeating device at, the received signal is led to a storage part 32, wherein it is stored while the transmitter-receiver receives the radio wave of the f1. The start and stop of reception can be known by a reception part squelch signal, so a control part 33 starts and stops the operation of the storage part 32 with the squelch signal. Simultaneously with the stop of the operation of the storage part, the received signal stored in the storage part 32 is added to a transmitter-receiver demodulation input 32 by being read from its beginning. Simultaneously, the control part 33 controls the transmission control terminal of the transmitter-receiver to place in the transmitter-receiver 31 in a transmission state.

Abstract: PURPOSE:To establish a high-speed, high-precision connection between a semiconductor chip and circuits on a substrate by a method wherein the moving distance of a semiconductor chip is minimized, positional deviation between the substrate and semiconductur chip is detected, and a function is provided to accomplish positioning by correcting the positions of X, Y, and theta by means of a positioning device. CONSTITUTION:An optical detector 30 detects the position of a substrate 27. When the detection is over of the positions of the semiconductor chip 20 and substrate 27, positioning devices 24, 26 operate to compensate for the distances X, Y between the optical detectors 29, 30 and a needle 23. A process follows wherein alignment is accomplished whereby the center of the semiconductor chip 20 and the center of a lead 28 of the substrate 27 are positioned on the center of the needle 23. A guide 22 and the needle 23 descend, depressing an adhesive film 19. The guide 22 is caused to stop descending when the gap between the semiconductor chip 20 and the lead 28 is narrowed to 0.3mm-0.5mm. The needle 23 only is allowed to go on descending until bondage is established between the pad 21 of the semiconductor chip 20 and the lead 28.

Title: Production of spherical ethylene resin particle
Inventor: YAMAI FUMITO
IPC: C08J9/16
Filed: 1984-06-26
Abstract: PURPOSE:To facilitate the production of spherical particles which can be expanded at a high expansion ratio, by suspending a pelletized or powdered ethylene resin in a liquid containing a dispersant, adding a styrene monomer thereto, heating the mxiture and polymerizing it in the presence of a polymerization catalyst. CONSTITUTION:100pts.wt. pelletized (cylindrical) or powdered ethylene resin is dispersed in a liquid containing a dispersant (e.g., magnesium pyrophosphate or calcium tertiary phosphate) and having a surface tension controlled in the range of 36-65dyn/cm (as measured at 25 deg.C). To this dispersion is added about 30-150pts.wt. styrene- or p-methylstyrene-based monomer, and the resulting mixture is heated. Because of the controlled surface tension, the mixture can be formed into spherical particles at a relatively low temperature. The resulting mixture is polymerized in the presence of a polymerization catalyst to produce spherical resin particles. These resin prticles can be expanded at a high expansion ratio when used as expandable resin particles.

Title: Flexed vibration converter
Inventor: KASAI YOSHIHIKO
IPC: H03H9/24
Filed: 1979-10-16
Abstract: PURPOSE:To ensure a reduction of the input impedance over a wide band, by connecting the elastic plate to the two piezoelectric porcelain plates in the longer direction and then securing such arrangement in that the residual polarizing directions of these two porcelain plates may be opposite to each other. CONSTITUTION:The elastic plates 6 and 7 made of the constant elastic material are connected to the thickness slip mode piezoelectric porcelain plates 8-0 and 8-1 each in the longer direction to form a flexed vibration converter. Then the plates 8-0 and 8-1 are arraged so that the residual polarizing directions of these plates may be opposite to each other and also vertical to the longer direction. In such constitution, the alternating electric signal is applied betwen the support lines 9/10 and the lead wire 11. As a result, the plates 8-0 and 8-1 receive the shearing stress as shown by the arrows A-D to produce a flexion as shown by the dotted lines in the figure. In this case, the plates 8-0 and 8-1 are inserted in parallel to each other in terms of electricity to secure the parallel exitence of the buffer capacity. Thus the input/ output impedance can be reduced. On the other hand, the equivalent capacitance is also increased to maintain the wide-band characteristics.
