Abstract: PURPOSE:To relieve a stress applied to the joint part between a board and a semiconductor chip, avoid damages and improve the reliability. CONSTITUTION:A semiconductor chip 20 is mounted on a board 10 with die- bonding material 30 filling a joint region 11. In the joint region 11, protrusions 12 are arranged so as to have intervals corresponding to the respective expansion coefficients of the board 10, the semiconductor chip 20 and the die bonding material 30.

Abstract: PURPOSE: To obtain an optical source device having high reproducibility and a high yield rate, easy to drive, and capable of obtaining large-output short pulse light by causing a semiconductor laser to operate by short pulse current. CONSTITUTION: When forward current 20 is caused to flow into an electrode 13 in an optical amplification region, the optical amplifying part operates. High- frequency current 21 is caused to flow into an electrode 12 of a DFB laser 2 to pulse-oscillate the DFB laser 2, and optical amplification is performed. At this time, it is possible to use a phenomenon that an energy grain near to an amplification characteristic of a small signal gain is obtained up to a region where the peak energy of output pulse light is sufficiently high, when a short pulse beam of a rise time shorter than a carrier life time caused by induced emission in the laser medium strikes the laser medium excited at the optical amplification region.  Here, high-frequency current 21 is caused to flow and the DFB laser 2 is driven to make it possible to obtain triangular pulse light of a half-value width 100ps and a peak power 10mw, and forward current of 20A is caused to flow into the optical amplification region 1.

Title: Cloth for rubbing of liquid-crystal display device as well as apparatus and method for rubbing containing it
Inventor: KIN HIYUNDE
IPC: G02F1/1337
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To increase the angle of visibility without any need of increasing the number of processes by including many zones having different fluff length from each other. SOLUTION: A roller 1 with a fabric of long fluff length such as velvet wound around is rotated and made to pass along the upper surface of a liquid crystal display substrate 3 having an orientation film 2 formed thereon. A rubbing cloth wound around the roller 1 is formed to have, for example, A-zones with long fluff length and B-zones with short fluff length, and a rubbing force acting on the orientation film 2 of the substrate 3 is thereby made different for every small part of the substrate 3. In this case, the A-zones and the B-zones are preferably laid alternately and regularly in a repeated way, and a bearer 4 and the roller 1 are driven so that the breadth of each zone corresponds to one picture element of the substrate 3.  One picture element formed on the substrate 3 is subjected to the same rubbing force and other picture elements adjacent to each other are subjected to a different rubbing force. According to this construction, each type of zones can be formed to have a different inclination angle between a liquid crystal molecule and the substrate 3.

Title: Lead accumulator battery active material composite
Inventor: MIZUMOTO MAMORU
IPC: H01M4/62
Filed: 1990-11-30
Abstract: PURPOSE:To improve the mechanical strength of an electrode plate and prevent the fall of an active material from the electrode plate by slurrying at the time of charge and discharge by adding a specified amount of a specified ring polysaccaride into the active material raw material of a lead accumulator. CONSTITUTION:0.1 to 10wt.% of a ring polysaccharide represented by the formula I is added into an active material starting material. The molecular weight of the ring polysaccharide can be changed by regulating the polymerization degree, and a solution having a viscosity most suitable for the kneading of starting lead powder and the charge to a lattice can be obtained. In the kneading process, a liquid phase containing the ring polysaccharide forms a film around the starting lead powder particle, and this structure is changed to a structure in which the ring polysaccharide having a high molecular weight binds the lead powder particles when the liquid phase is extinguished through maturing process. When charge and discharge are repeated, the ring polysaccharide is gradually converted into a material similar to a non- crystalline carbon having a three-dimensional network structure. This change further strengthens the binding between the active material particles by the formation of the three-dimentional network structure. Thus, the mechanical strength of an electrode plate is improved, and the fall of the active material particle from the electrode plate at the time of repeating the charge and discharge can be suppressed.

Abstract: PURPOSE:To recover the timing clock of an NRZ signal without using a timing tank by providing a PLL phase-locked with the output signal of an external synchronizing oscillator whose speed is set nearly equal to the bit speed of the NRZ signal. CONSTITUTION:In the reception of the NRZ signal S1 with jitter, an edge detection circuit 1 detects the code change point of the NRZ signal S1 and inputs a signal S2 in response to the code change point to an external synchronizing signal terminal of an external synchronizing oscillator 2. The oscillator 2 is oscillated synchronously with the signal S2 and the signal S3 is given to the phase locked input terminal of the PLL 3. The oscillating period T of the signal S3 is equal to a lit interval or the NRZ signal S1 or nearly equal thereto, even when any change point exists in the NRZ signal S1, the timing pulse is generated and even in the absence of a change point, the signal S3 supplies the clock.

Filed: 1990-11-29
Abstract: PURPOSE:To extend the range of extension selection and to improve the service by searching an idle extension in an extension representative group selected according to the selection priority in the case of selecting an extension. CONSTITUTION:When a PBX 10 detects an incoming call by an extension number, the PBX 10 references a table to discriminate whether or not an extension representative group is arranged as an extension large representative group. When not arranged in such a way, extension representative processing is implemented and when arranged in this way, an extension representative group 1 whose priority is highest in the extension number is selected and an idle extension is sought in the order of extensions B, C, A, D in the order of priority. When an idle extension is in existence, the processing to receive the extension is implemented and when no idle extension is in existence, an extension representative group 3 in a 2nd priority in an extension large representative group I is selected and similarly, an idle extension is sought in the order of extensions H, J, I according to the priority in the extension representative group 3. Thus, the service is improved.

Abstract: PURPOSE:To feed out refrigerant to a defrosting circuit in a short time, and to eliminate an increase in a defrosting time due to insufficient refrigerant amount by forcibly feeding out the refrigerant weighed by a weighing unit with the discharging pressure of hot gas to be discharged from a compressor. CONSTITUTION:A refrigerant amount necessary for a defrosting operation of refrigerant enclosed by the closing operation of a first solenoid valve 30 is weighed by a weighing unit 33 by the closing operation of a second solenoid valve 32. The weighed refrigerant is fed out to an evaporator 4 by the opening operation of the valve 30, and forcibly pressed to a defrosting circuit by the discharging pressure of the hot gas to be discharged from a compressor 1 by the switching operations of a hot gas valve 21 and a three-way switching valve 34. Since the pressing time is normally completed within 20sec, its time is measured in advance to be set to a timer, the valve 34 is switched, after the set time is elapsed, to close an inlet path 35, thereby stopping the introduction of hot gas to the unit 33. After the pump down operation is finished, the defrosting operation can be immediately started.
