Title: Clock reproducing circuit
Inventor: KATOU KOUTAROU
IPC: H04L7/10
Filed: 1981-07-28
Abstract: PURPOSE:To prevent the generation of insensible section and to realize a stable clock reproduction, by stopping the detection without a timing component until the timing component arrives by predetermined numbers after arrival of a burst to the reception side. CONSTITUTION:A reception signal (p) is inputted to a burst detection circuit 21. The circuit 21 detects the section existing in the burst with the signal (p) and generates a pulse (q) indicating the head timing. The pulse (q) is used as the driving signal of an L notation counter 22 and sets the 4th FF23. If a pulse is generated to an output (r) of the counter 22, the FF23 is reset. At the section generated with a pulse to an output (s) of the FF23, an output (m) of an absence of timing detection circuit 13 is not given to the output of a circuit 24 with the 5th AND circuit 24. Then, at the leading process head reproducing the clock from a burst signal, no insensible section is generated and a smooth pull-in process can be realized.

Filed: 1991-05-22
Abstract: PURPOSE:To keep off an electric leak or the like to the outside in draining leaked water from a pump part till it is reached to an output shaft, by setting up a drain board, for preventing the water from shifting to a motor as going along the output shaft, in a boss part at the more rearward than a leakage preventer. CONSTITUTION:In this centrifugal pump 10, when an impeller 56 rotates with rotation of an output shaft 26, water is drawn in from an intake 54, and it is discharged out of a discharge port 55 by way of an impeller inner chamber 59. In this case, a mechanical seal 67 is broken, leaked water out of a pump case 40 passes through an inner part of the mechanical seal 67. Accordingly, the leaked water toward a boss part 80 after passing through the inside is scattered by a rotating drain board 65 till it is reached to the output shaft 26. With this constitution, such a possible accident that an electric leak to the outside might be caused is thus obviated. In this connection, the drain board 65 is made of an insulator such as rubber or the like, and the mechanical seal 67 is installed in the rear of the boss part 80 being set up in the circumference.

Title: Semiconductor device
Inventor: SHIMIZU AKIHIRO
IPC: H01L29/68
Filed: 1986-05-23
Abstract: PURPOSE:To construct a high-performance basic device structure by a method wherein a Schottky junction is formed between metal and low-concentration semiconductor and electrodes are built on them through the intermediary of an insulating film. CONSTITUTION:An N<+>-layer 2 is kept at a drain voltage VD, a gate electrode 3 at a gate voltage VG, and a metal layer 5 at the ground potential. When a positive voltage (VD>O) is applied only to the drain N<+>-layer 2, no current flows although a Schottky barrier depletion layer in an N<->-layer 1 extends toward a silicon side. Next, when the gate voltage VG is also rendered positive, the Schottky barrier will be so thin that electrons will tunnel from a metal layer 6 into the N<->-layer 1 for the performance of switching actions. In this case, the N<+>-layer 2 contacts with external circuits. It becomes possible for a current flowing from the drain N<+>-layer 2 to a source metal layer 5.

Title: Operation button mounting structure of electronic device
Inventor: CHIBA KOJI
IPC: H01H21/00
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To enable a fulcrum part to be arranged in the vicinity of a front face finish plate opening, significantly improve a back face space factor, miniaturize it, and reduce restrictions of design degree of freedom by providing the fulcrum part and an elastic part at one end of an operation knob. SOLUTION: An operation button 1 is provided with a fulcrum part 1b and an elastic part 1c at one end of an operation knob 1a, and a hinge function required for operation is obtained by utilizing slackness of the elastic part 1c. Thus, the fulcrum part 1b can be arranged in the vicinity of an opening 2a of a front face finish plate 2, and the elastic part 1c can be arranged in an area directed from the vicinity of the opening 2a to the backward. Therefore, in the circumference of the opening 2a, a part excessively distant from the opening 2a does not need to be utilized as a space for mounting the operation button 1.  Thus, in the case of a car mounting acoustic device, by means of the operation button having such a mounting structure, a space factor can be significantly improved in a face along the back face of the front face finish plate 2, miniaturizing of a product can be easily promoted, and restriction on the design degree of freedom is reduced.

Title: Magnetic field type energy filter
Inventor: OIKAWA TETSUO
IPC: H01J49/44
Filed: 1985-05-31
Abstract: PURPOSE:To eliminate an optical aberration causing to produce distortion of image, a dim image, deterioration of energy analysis ability, and the like, and improve the energy filtering capability, by giving an inclination to the magnetic flux distribution in a bowl piece. CONSTITUTION:A gap t formed in a bowl piece 20 is made the farther from the light axis Z, the narrower the gap. Therefore, the incident electrons into the bowl piece 20 make the magnetic flux density B smaller and the rotation radius r larger near the light axis Z, and, the magnetic flux density B larger and the rotation radius smaller as apart farther from the light axis Z, thus converting the rotation radius r responding to the magnetic flux density B within the bowl piece 20. Therefore, an incident electron to the bowl piece can be turned back to the light axis Z in a locus shown as No.2 in the bowl piece with only one direction of magnetic field. In that, there occurs no free space without magnetic field, because only one bowl piece is used, and the resultant aberration can be removed.

Title: Thermal recording paper
Inventor: KOIKE KAZUYUKI
IPC: B41M5/28
Filed: 1985-05-31
Abstract: PURPOSE:To obtain thermal recording paper excellent in both of color forming density and image quality (dot reproducibility), by setting the density of a paper support to 0.98g/cm<2> or less, the center line average roughness (wavelength 250mum) thereof to 0.70mum or less and the Cobb water absorbancy (JIS-P-8140) to 10-20 g/m<2>. CONSTITUTION:If the center lien average roughness of a paper support is made larger than 0.70mum, dot reproducibility to be satisfied is not obtain. in order to make the center line average roughness small, it is important to apply super calender processing to the paper support to raise the density thereof but, if density is made higher than 0.98g/cm<2>, paper cratering is generated or the rigidity of paper is lost. When Cobb water absorptiveness 20g/m<2> or less, the deterioration of surface smoothness at the time of the coating of a thermal coating layer is reduced and, therefore, recording density is high at the time of thermal recording and dot reproducibility is well. When Cobb water absorbancy reaches 10 g/m<2> or less, the wettability of the thermal coating solution to the paper support is deteriorated and, at the time of high speed coating, it is not pref. because minute uncoated parts are partially generated.

CONSTITUTION:A probe main body 1 is inserted in a blood vessel 18 through the channel of an endoscope 17 and laser beam is allowed to irradiate a thrombus part 19 from a ceramic chip 7 to cauterize and remove he same. At this time, since the probe main body 1 is stably held at the approx. center of the blood vessel 18 by am spacing chip 9, the puncture of the blood vessel due to laser beam can be prevented. Since a circular arc-shaped notch part 11 is provided to the spacing chip 9, the interior of the blood vessel 18 beyond the spacing chip 9 can be observed by the endoscope 17. Therefore, the thrombus part 19 can be treated while the irradiation position with laser beam is confirmed by the endoscope 17. Further, since the blood vessel 18 is not closed by the spacing chip 9, the flashing of a physiological saline solution can be easily performed.
