Title: Hollow light leading body
Inventor: TATEISHI FUMIKAZU
IPC: G02B6/02
Filed: 1987-01-12
Abstract: PURPOSE:To obtain a hollow light leading body having high transmission efficiency by sticking a thin dielectric film to metallic foil, winding the same to a cylindrical or spiral shape in such a manner that the thin dielectric film is positioned on the inside and forming a sheath to the outside thereof. CONSTITUTION:A dielectric material 2 of germanium is deposited by vacuum evaporation on the aluminum metallic foil 1 subjected to mirror finishing on the surface. The thickness of the dielectric film is selected by taking the wavelength of a laser and the inside diameter of a light guide path, etc., into consideration minimize the loss to the lowest level. Since the film is deposited by evaporation on a flat surface, the control of the film thickness is easy. The aluminum foil 1 on which the dielectric material 2 is deposited by evaporation is spirally wound to the hollow shape of 0.5mm diameter. The surface of the aluminum foil is specular and the dielectric material formed atop said surface is specular as well; in addition, the film is formed to the exact film thickness. The sheath 3 of an aluminum tube intensifies the mechanical strength of the aluminum foil and improves heat radiation so that laser light of high output can be transmitted. The transmission of the laser light with high efficiency is thus permitted.

Title: Coordinate input device
Inventor: YOSHIMURA YUICHIRO
IPC: G06F3/03
Filed: 1994-01-20
Abstract: PURPOSE:To eliminate the interference of plate symmetrical waves and to reduce influence on plate asymmetrical waves by measuring the time from the input of vibration to a vibration transmission plate until the detection of the vibration based on the vibration of a separated single mode and calculating the coordinates of a vibration source based on the measured vibration transmission time. CONSTITUTION:The vibration transmission plate 8 is touched with a vibration pen 3, coordinate input is specified and signals from respective vibration sensors 6a-6d are detected in a vibration waveform detection circuit 9. For the detected signals, in an arithmetic control circuit 1, the vibration transmission time until the respective vibration sensors 6a-6d is measured based on the vibration of the separated single mode and the coordinate position of the vibration pen 3 is calculated based on the measured vibration transmission time. Thus, the interference of the plate symmetrical waves is eliminated, the influence on the plate asymmetrical waves is reduced and the precision of position coordinate detection is improved.

Title: Fluid pressure digital throttle valve
Inventor: DESAKI MASAYASU
IPC: G05D16/18
Filed: 1979-01-18
Abstract: PURPOSE: To enable controlling of a throttle valve by digital signal, by using a spool which formes the throttle portion of spool as the secondary curved surface.  
     CONSTITUTION: The opening area of the throttle is zero at the position which the maximum diameter of the secondary curved surface 4a on the spool 4 touches to the right side wall 1g of the annular groove 2a. When positive pulse voltage is applied to the pulse motor, the motor rotates by degree in prorportion to the pulse number rightward. This rotation is transmitted to the coupling 8 and the pin 9, permitting a screw 6 to rotate leftward viewed from rear. When the screw 6 and the nut 1f have right hand threads, the screw moves backward by degree in proportion to pulse number, the spool 4 is also pushed by a spring 5, moving backward by degree in proportion to pulse number. The shape of the secondary curved surface 4a is fixed to be in proportion to the change of spool for the throttle opening area formed between the secondary curved surface 4a and the edge 1a, therefore the control flow can be changed in proportion to pulse number.

Title: Schottky barrier diode
Inventor: TAKEDA MITSUGI
IPC: H01L29/872
Filed: 1980-01-18
Abstract: PURPOSE:To improve electric characteristics in a Schottky barrier diode which has a buried layer between a semiconductor substrate and an epitaxial layer by etching the epitaxial layer under electrodes so as to form one electrode on the buried layer  and the other a little above the layer. CONSTITUTION:An N<+> buried layer 2, an N type epitaxial layer 3 and an insulating film 6 are formed on a P type silicon substrate 1. By etching the part of the epitaxial layer where an anode electrode 8 is to be formed to the extent that the buried layer may not be exposed, the anode electrode is formed.

Title: Work taking out device
Inventor: IZEKI IKUO
IPC: B23P19/00
Filed: 1985-01-14
Abstract: PURPOSE:To make it possible to count the number of works with excellent accuracy and carry out every fixed number of works to the next process by providing a work taking out device with a carrying conveyer and a feeding conveyer operated at high feed speed in series to form a gap between works. CONSTITUTION:Works W which are fed at random on a carrying in conveyer 2, being near or apart one another, form a gap G between the works W when transferred onto a feeding conveyer 3 operated at high feed speed. A detector 9 can therefore correctly count the number of the works W. In addition, when the stopper 4 of a stopper element 5 rises to tilt a feeding conveyer 6 downward, the works W strike the stopper 4 and then stop there. A detector 10 ascertains that the final work counted by the detector 9 has stopped at the rear of the preceding works W. At this time, the detector 10 extends a cylinder 67 according to its ascertaining output to tilt the feeding conveyer 6 upward. Thus the works W are raised, and the stopper 4 is also lowered to carry out the works W to the downstream side.
