IPC: G11B17/28
Filed: 1984-09-18
Abstract: PURPOSE:To correct a weight-unbalanced condition and improve the positioning accuracy of a medium to its housing and a read/write station, by fitting a counter weight for adjusting unbalance of rotating weight to a medium holding section. CONSTITUTION:A medium holding mechanism section 12 is advanced toward a housing 2 by means of a ball screw 11 and pulls a medium 1a into the mechanism 12 by grasping the protecting frame 1 of the medium 1a. A chassis 8b rotates upward or downward around a shaft 15 and inverts the medium 1a to a horizontal attitude, and then, inserts the medium 1a into a read/write station 3. Since the medium holding mechanism section 12 coupled with a base section 8a by means of the shaft 15 is offset from the shaft 15, the section 12 is very unstable under a vertical condition. However, the stability in the vertical condition is improved and the medium putting-in and taking-out operations to and from the housing 2 are smoothly performed, since the unbalance of the rotating weights is adjusted by fitting a counter weight 14.

Filed: 1990-07-24
Abstract: PURPOSE:To automatically set correct time information constantly by detecting a time signal from a multiplex signal on a broadcast wave and automatically correcting time of a time counting means. CONSTITUTION:A TV signal received by a TV signal reception circuit 11 is sent to a display unit 14 to be displayed. In this case a teletext multiplex broadcast signal multiplied on the TV signal of a broadcast station A is decoded by a teletext signal decoding circuit 12, from which signal a control circuit 13 detects time information broadcast by an S company. At this time since a transmission sequence of the time information in teletext multiplex broadcast provided by the S company is predetermined, the control circuit 13 can detect correct time information by receiving it according to the sequence. After the detected time information is subjected to correction such as a time lag from time information required by a user, it is set in a time counting circuit 16. Since the correct time information is thus automatically set in the time counting circuit 16, correct time management is possible by operating a timer, etc. based on the time information.

Abstract: PURPOSE:To prevent a glitch noise from occurring by providing a selector which selects either of input A or B by a select signal, a noise mask generation circuit which delays the input A, and a noise masking circuit which synthesizes the output of the selector with that of the noise mask generation circuit. CONSTITUTION:When the select signal is set at an H level, the selector 1 selects the input A, and outputs it to the noise masking circuit 3 after being delayed by the noise mask generation circuit 2. The circuit 3 outputs the OR of the selector 1 and the input A to the circuit 2. When the select signal goes to an L level, the output of the circuit 2 goes to the L level, however. the output of the circuit 3 remains at the input A as it is. Following that, the input B is outputted from the selector 1 to the circuit 3 being delayed by the switch delay time of the selector 1. At this time, since the output of the circuit 2 remains at the input A as it is, the output of the circuit 3 goes to the OR of the input A and B. Furthermore, the output of the circuit 2 goes to the L level being delayed by the delay time of the circuit 2, the output of the circuit 3 goes to the input B.

Title: Semiconductor device
Inventor: SAWADA KOUKICHI
IPC: H01L23/52
Filed: 1981-12-02
Abstract: PURPOSE:To manufacture the semiconductor device in which an internal circuit section is not broken by surge applied to an input circuit section and can be protected effectively and surge resistance can be improved even when the input circuit section and the internal circuit section are brought close and the degree of integration is increased. CONSTITUTION:A diffusion layer 5 connected to a GND line is formed between the diffusion layer 1 of the input circuit section and the diffusion layer 2 of the internal circuit section. Surge applied to the input circuit section is absorbed to the GND through the N<+> diffusion layer 5 because the N<+> diffusion layer 5 connected to the GND line is shaped between the N<+> diffusion layer 1 of the input circuit section and the N<+> diffusion layer 2 of the internal circuit section in the semiconductor device according to this constitution. Consequently, the surge resistance of the semiconductor device is improved remarkably because surge is not transmitted to the N<+> diffusion layer 2 of the internal circuit section. An area required for shaping the N<+> diffusion layer 5 is minute, and the diffusion layer 5 can easily be formed into a high integrated circuit.

Title: Cap device of liquid injection recording head
Inventor: KOBAYASHI TORU
IPC: B41J2/18
Filed: 1987-08-07
Abstract: PURPOSE:To enable continued adsorption of discharged recording liquid always in stable condition by extending an adsorption member, one end of which upper part is caused to come into contact with the discharge surface of a recording head downward and also setting one end of the upper part of the adsorption member above a head of water suction maintained when the adsorption member is impregnated with recording liquid. CONSTITUTION:The upper end of an adsorption member 31 is caused to come into contact with the discharge surface of a recording head 1. When the lower end 31A of the adsorption member 31 is immersed in recording liquid 33 in a container 32, the recording liquid 33 is gradually sucked by the adsorption member 31 due to capillarity. When a suction head reaches a prearranged height H0, it becomes balanced, and the recording liquid 33 discharged from an orifice is adequately adsorbed and held above a height equivalent to the head of water suction H0. In addition, the recording liquid 33 adsorbed in the part above said height descends as it is by gravity to be stored in a container. Subsequently, the adsorption member 31 itself properly adsorbs and discharges the recording liquid 33 without the necessity to squeeze out the recording liquid 33 because the storage into the container compresses the recording liquid.
