Title: Pll circuit for information reproducing device
Inventor: HOSOYA HIDEKI
IPC: G11B7/005
Filed: 1987-07-23
Abstract: PURPOSE:To minimize the pull out of a PLL at the time of the omission of a reproducing signal by setting the sensitivity of the titled PLL circuit in accordance with the level of an automatic tracking error signal at the time of reproduction. CONSTITUTION:In a range where the absolute value of an AT error signal S3 is small, the cut-off frequency of an LPF 2 is comparatively high, the attenuating quantity of an attenuator ATT 4 is comparatively small, and the sensitivity of a PLL is comparatively high. When a position relation between a light spot and an information track largely varies with some reason, and the absolute value of the signal S3 exceeds the reference value of a comparator 7, the switching signal S5 goes to 'H', the switches SW1 and SW2 are switched to the side of a capacitor C1 and a resistance R3, the cut-off frequency of the LPF 2 goes to low, the attenuating quantity of the ATT 4 goes to large, and the sensitivity of the PLL goes to low.

Abstract: PURPOSE:To omit a troublesome finishing process by attaching powdered epoxy resin to the rotor or the stator, the coil thereof is conducted and heated, blowing off the epoxy resin of sections except the coil and melting and curing the epoxy resin. CONSTITUTION:The coil of the stator S is conducted and heated so that the coil reaches approximately 80 deg.C and other sections 25-30 deg.C, the stator S is entered into a vessel 9 in which the powdered epoxy resin 11 is placed onto a filter 10, and air is blown in from a lower port 9a, thus attaching the powdered epoxy resin 11 to the whole stator S. Here, the powdered epoxy resin adhering on the coil of the stator S is brought to a state that solidly adheres because of the high temperature of the coil, but other sections are brought to states that powder simply adheres. Powdered epoxy resin adhering on sections except the coil is blown off by means of air spray-up devices 13, 14 while the stator S is turned by means of a revolution supporter 12, and lastly the epoxy resin adhering on the coil is melted and cured. The same applies to the rotor.

Title: Semiconductor memory device
Inventor: OOTANI TAKAYUKI
IPC: G11C11/34
Filed: 1983-09-30
Abstract: PURPOSE:To attain the reduction and the large scale integration of a memory cell area and to realize a high working speed and low power consumption with a semiconductor memory device by using a word line which controls plural transfer gates independently of each other and securing a simultaneous access to unit recording circuits with different addresses. CONSTITUTION:A memory cell 11 is selected by the word line 1WL for the 1st port. Then data are read out and written to the cell 11 via a bit line 1BL for the 1st port. Then the cell is selected by a word line 2WL for the 2nd port. Thus data are read out and written via a bit line 2BL for the 2nd port. Therefore the simultaneous or single access is possible to the same cell through both port or a single port. In such constitution, two wirings for the bit lines and two transfer MOS transistors can be omitted compared with a conventional circuit. This attains the large scale integration as well as a high-speed operation and low power consumption for the semiconductor memory device.

Title: Corrugated panel
Inventor: TERASONO MITSUO
IPC: B32B3/18
Filed: 1989-07-15
Abstract: PURPOSE:To prevent bent part from yielding even when external force is applied to the crest of the bent part by a method wherein spacer is provided between the inner surface of the crest of each bent part of corrugated surface plate and base plate so as to support the crest of the bent part from its rear side with the spacer. CONSTITUTION:Spacer 4 such as sticker or the like is inserted between the back of the crest of bent part 1 and the front of the base plate 3 throughout their whole length. Corrugated surface plate 2 is bonded to the base plate 3 at the base of each bent part 1. Further, by bonding the spacer 4 to both the base plate 3 and the corrugated surface plate 2, the crest of each bent part 1 is also bonded through the spacer 4 to the base plate 3. At the edge of a corrugated panel A produced as mentioned above, frame members 8 and like are mounted, when necessary, so as to be used by being worked to furniture door, movable partition door or the like. Since the crest of the bent part is supported from its rear side with the spacer 4, the spacer 4 can prevent the bent part 1 from deforming by yielding, even when external force is applied to the outer surface of the crest of the bent part.

Title: Lead frame for resin-sealed type semiconductor device use and manufacture thereof
Inventor: ISHIGURO TSUTOMU
IPC: H01L21/56
Filed: 1989-07-14
Abstract: PURPOSE:To eliminate a need for a process used to remove a resin burr by a method wherein, in a dam structure, a shape whose head has been spread to be a T-shape near a side face of a resin is provided and opposite faces have a very small interval with reference to an external terminal. CONSTITUTION:When a lead frame is manufactured, a wedge-shaped groove 6 is formed at the head of a dam structure by using a press punch. That is to say, a resin which has been injected by means of a T-shaped head 5 of a dam rod 4 is dammed up by a top face 7 of the dam rod. The press punch 9 is put into the wedge-shaped groove 6 at the head of the dam rod; side-face parts at the head of the dam rod 4 which has been pressed with the press punch 9 are pushed in a side-face direction of an external terminal 2, and their interval becomes a minimum structure. Since the top face 7 of the dam rod is arranged in nearly the same position as the side face of the resin in this manner, a resin burr is not produced. In addition, since a T-shaped side face of the dam rod 4 and a side face of the external terminal 2 come into contact with each other or form a very narrow interval, it is possible to prevent the resin from being leaked along the side face of the external terminal.

Abstract: PURPOSE:To improve responsiveness and sensitivity by forming a heat sensitive thin-film body and an IR absorptive layer on the front surface of a substrate, forming the rear side thereof as a space and installing an IR transmission filter in the route for IR rays. CONSTITUTION:The heat sensitive thin-film body 2 and the IR absorptive layer 5 are formed on the front surface of the substrate 1 laminated with an insulating layer 1a on a semiconductor layer 1b and the space S is formed on the rear side thereof. The IR transmission filter 7 is installed in the route for the incident IR rays to the absorptive layer 5. The sensor is microminiaturized by the use of the thin-film body 2 and the heat sensitive part consists of the small thickness part A of the substrate 1 and the thin-film body 2 and is small in thickness as a whole so that this part has an extremely small heat capacity and extremely good responsiveness. The space S communicates with the front surface in the relation with the part A to form the non hermetically closed state and the part where the volume of the air in the space S is increased and decreased by a temp. change is replenished and discharged. The accuracy of the measurement is thus maintained without allowing the part formed with the thin-film body to be deformed.
