Patent JP-H0367351-A (JP)
Title: Semiconductor device
Inventor: HAYANO KOJI
IPC: H04L13/08
Filed: 1989-08-05
Abstract: PURPOSE:To eliminate the discordance of contents between a status register and a received data buffer of a UART by allocating these register and buffer to the same address. CONSTITUTION:The received data RXD inputted to a UART is shifted by a shifter 8 at a communication Baud rate. A buffer 9 holds the received data, and a control circuit 10 produces a signal showing the reception state of the UART and stores the signal in a register 11. When the serial input data RXD is inputted to the shifter 8 by a piece of data, a reception end signal 13 is asserted. Then the received data are sent in parallel to the buffer 9 from the shifter 8. The UART usually sends an interruption signal to an interruption controller, and a CPU reads 14 simultaneously the received data and the status of the UART. When the register 11 doubles as a transmitter and a receiver, only the status is read at occurrence of a transmission interruption. In such a constitution, the coincidence of contents is secured between the received data and the status.

Title: Automatic iris correction circuit for television camera
Inventor: MAEZATO SHINICHI
IPC: H04N5/238
Filed: 1988-08-17
Abstract: PURPOSE:To always keep a video signal output level properly against the camera sensitivity changeover in operation by deciding a correction value of an iris control signal to each setting sensitivity in advance and correcting the iris control signal to the setting automatically. CONSTITUTION:When a setting value is switched by a sensitivity setting circuit 5, a microcomputer 61 reads a data of a predetermined control voltage in response to the setting value from a memory 62. The data is converted into an analog voltage by a D/A converter 63 and fed to a remote terminal 47 as a correction control signal. Then an automatic iris control signal 4 adds a correction control signal to a peak value to apply fine adjustment to the iris control signal. Thus, the incident light passes through the iris 1 to be controlled and is converted into an electric signal by an image pickup element 2 so as to keep the level of the video signal to a proper value at all times independently of the sensitivity setting via the amplifier 3.

IPC: G03G5/047
Filed: 1993-08-18
Abstract: PURPOSE:To improve sensitivity without decreasing mobility when two or more kinds of charge transfer materials are mixed and used by controlling the ionizing potential to a specified value. CONSTITUTION:A hydrazone compd. expressed by chemical formula I (with 5.05eV ionizing potential) and a diamine compd. expressed by formula II (with 5.10eV ionizing potential) as charge transfer materials in total 5 pts.wt. and 5 pts.wt. of polycarbonate resin are dissolved in dichloromethane to prepare a coating liquid for transfer of charges. Then a charge transfer layer is formed on a polyester terephthalate film on which aluminum is vapor deposited. In this process, when the difference of ionizing potentials between charge transfer materials is less than 0.1eV, the number of hole traps in the photosensitive layer decreases and sensitivity can be improved.

Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To obviate any possible falling of a bolt being under construction by attaching each of soft plastic rings to a necking part of the bolt and the border line of a thread part. SOLUTION: A necking part 2 is provided in a spot nearby the bolt head of the lower neck of a bolt 1, and a soft plastic ring 4 is attached to a border line between this necking part 2 and a thread part 3. This ring 4 is larger than a metal fitting hole 5 where the bolt 1 is inserted, but there is such a sized one attached, which is deformed, such magnitude as being insertable in the metal fitting hole 5, and not pulled out with the bolt's own weight alone. In this ring 4, a spot nearby the head of the bolt 1 is broad, flat, and an intermediate part has a taper, and another spot nearby the thread part is formed into a skirt form being diametrally narrowed.  With this constitution, when it comes into the metal fitting hole 5, admission takes place from its diametrally small side, so that it is easily carried out, and further, since a diametrally large part comes into contact with the hole, it is so designed as to be hard to slip out in terms of structure.

Abstract: PROBLEM TO BE SOLVED: To surely remove dust and mist adhered on the inner surface at arbitrary moment in operation by sending in and drawing out a chain body fixed by a cleaning tool at the tip end in an exhaust pipe and reduce the radiation dose of workers. SOLUTION: A cleaning device is constituted of a cleaning introducing pipe 11, a chain body 12, a cleaning tool 13, a chain driving means 14 and a connection pipe 15. First, the chain body 12 is wound up and the cleaning tool 13 at its tip end is placed on standby at above the introducing pipe 11. At this moment, off-gas is exhausted from an off-gas exhausting pipe 4 to the connection pipe 15. In the case adhesive Y has adhered on the inner wall surface of the exhaust pipe 4 during the operation of a glass melting furnace, the chain body 12 is sent out with the means 14 and the cleaning tool 13 is inserted inside the exhaust pipe 4. By reciprocally moving the cleaning tool 13 up and down with a driving source 14a, the adhesive Y is surely ground with each blade of the cleaning tool 13.  Therefore, cleaning work can be done in parallel to the operation of the melting furnace due to the gap G and the like and radiation dose of workers can be reduced owing to the use of the chain body 12.
