Title: Programmable generator
Inventor: TEIERII FUANSHI
IPC: H03B28/00
Filed: 1994-03-14
Abstract: PURPOSE: To obtain a programmable synthesizer reducing higher harmonics by generating a square wave signal having programmable frequency and controlling the capacitance value of an LPF based on the period of the signal. CONSTITUTION: A generator 13 generates a square wave signal having a programmable frequency. A counter 22 counts up the period of the square wave signal and a decoder 14 generates the value of a continuous discrete sine wave. Then the sine wave value is inputted to an LPF 20 consisting of a switched capacitor filter through a ROM 15 and a D/A converter 17. The LPF 20 is controlled its switching mode by a signal B8 of frequency proportional to the frequency of the square wave signal inputted from the counter 22 and suitably selects the value of the capacitor. Consequently the cut-off frequency of the LPF 20 can continuously match almost the same frequency as the sine wave and higher harmonics are reduced.

Title: Distance measuring device
Inventor: HOSHI TADAHIKO
IPC: G03B13/36
Filed: 1995-03-02
Abstract: PURPOSE: To irradiate a target object at a comparatively long distance by a sufficient quantity of light, and irradiate a target object at a comparatively short distance in a sufficient angle range by arranging a second area to emit a light flux from a light source at a second angle of emergence substantially larger than a first angle of emergence. CONSTITUTION: For example, a light flux from a light source 1 composed of a laser diode LD is sent toward a target object through a light sending lens 2. Two projecting parts B are formed in positions symmetric on the optical axis AX on a lens surface on the light source side of the lens 2. The projecting parts B locally project to the light source side from a peripheral lens surface, and its surfaces are formed into a spherical surface shape. Therefore, a light flux passing through the projecting parts B receives a refractive action stronger in a certain degree than a light flux passing through a lens surface A on the light source side of the lens 2. That is, among a light flux from the light source 1, a light flux incident on the lens surface A of the lens 2 proceeds to the target object while slightly diverging at an angle of emergence of θA. On the other hand, a light flux incident on the projecting parts B proceeds to the target object while diverging at an angle of emergence of θB larger than θA.

A primary winding N1 and an auxiliary source winding N3 are applied to the leg 2b. A secondary winding N2 is applied to the leg 2e. A control winding N4 is divided into two windings N4a and N4b. The control windings N4a and N4b are applied to the leg 2c and leg 2d respectively and connected in series. The flux of the winding N4a is added to the flux of the winding N4b. The magnetized condition of the legs 2c, 2d is changed by changing the current of the control winding. With this constitution, the width of the pulse generated by the secondary winding N2 can be controlled. As the four legs type rectangular core has a simple structure, the assembly is easy.

Filed: 1978-06-09
Abstract: PURPOSE: To enable change-over without providing an overcurrent blocking resistor nor reactor by arranging that winding portion of a starter transformer which is shorted by a contact on the tap change-over time around the same iron core as, and separately from, the other windings which are not shorted.  
     CONSTITUTION: A starter transformer ST-TR is fitted with taps U 1  and U 2  of R- phase, and windings 8, 9, and 10 are provided between a phase line R and the tap U 1 , between the taps U 1  and U 2 , and between the tap U 2  and a line U 0 . The winding 9 is arrange separately from the concentrically wound windings 8 and 10, and the others are arranged in the same way. Even when contacts 4 and 5 are closed and the winding 9 is shorted due to the change-over of the taps of the starter transformer ST-TR on starting time, the leakage reactance between the winding 9 and the other windings is so large that the crossing of the magnetic fluxes induced by the other unshorted windings is largely reduced. Thus, the short-circuit current is reduced without providing an overcurrent blocking resistor nor reactor.

Abstract: PURPOSE:To obtain a Schottky barrier diode high-pressure resisting for use on large current by a method wherein a plural windows are formed along an electrode window provided in an insulating film on a semiconductor substrate, which is covered with a barrier metal. CONSTITUTION:An SiO2 film is formed on an n<->-epitaxial layer on an n<+>-Si substrate 1, and fine windows W1, W2 are provided at a minute interval along a window W0. The window wall surface is then formed perpendicularly to the substrate face through a selected etching condition. Next, a barrier metal 3 is made. According to this constitution, resistance is increasing on the metal 3 in accordance as it proceeds from the window W0 to W2, therefore a potential difference is produced. A stretch 4 of a depletion layer is slanting mildly at the peripheral edge, and an electric field is not concentrated consequently. Then, since the barrier metal 3 is formed on the wondows W1 and W2 and the epitaxial layer of the substrate, a larger current capacity is obtainable than a conventional type. Further, the barrier metal covers an overall surface of the substrate, therefore an apprehension of exfoliation due to heat scarcely exists and a reliability is thus improved.

IPC: G01H13/00
Filed: 1992-02-10
Abstract: PURPOSE:To easily determine the shape of an object by detecting the change of the volume between a pipe and the object from the change of a gas in accordance with the law of gaseous reaction. CONSTITUTION:A pressure sensor 2 is provided at a side wall of a pipe 1 confronting an object 3 via a constant distance (d). The pressure sensor 2 using, for example, an electrostrictive material generates the distortion pressure when it is driven by the addition of a voltage. On the other hand, when the pressure is added from outside, the pressure sensor 2 detects a voltage signal. Therefore, when the pressure sensor 2 is driven to act a constant pressure inside, the volume of the internal gas is changed in compliance with the law of gaseous reaction. The repulsive force as the reaction of the volume change is detected as electric signals by tone sensor 2, so that the volume between the pipe 1 and the object 3 is detected. The volume represents a value corresponding to the shape of the object, and therefore the shape can be easily determined.
