CONSTITUTION:A reception signal outputted from a narrow-band amplifier 19 is branched off into two signals, and one signal is inputted to a synchronism detection output part 20, and synchronism detection is carried out with a single frequency (f0) given from a single frequency generator 3, and a phase component of this detection output is set as [e1(f)]. The other reception signal is also inputted to the synchronism detection output part 20, and synchronism detection is carried out with a signal whose single frequency (f0) is shifted by 90 degrees by a phase shifter 21, and a phase component of this detection output is set as [e2(f)]. These detection output pairs [e1(f) and e2(f)] are obtained by a plurality with every constant frequency, and are fed to an inverse Fourier transformer 22 as a real number part and an imaginary number part, and an impulse responsive waveform of a signal is obtained. This waveform is displayed (23) by changing a position of two boring holes, and an underground cross-sectional image is obtained.

Filed: 1981-08-31
Abstract: PURPOSE:To control overcurrent rapidly by reducing the slip frequency supplied to an induction motor when the overcurrent is generated in the induction motor in a frequency region higher than the rated frequency of the induction motor. CONSTITUTION:The command of an overcurrent detecting circuit 10 is inputted to a slip-frequency control circuit 8. When overcurrent is generated in an induction motor 3 in the frequency region higher than the rated frequency of the induction motor 3, the overcurrent is detected by means of the overcurrent detecting circuit 10, the slip frequency is reduced by means of the frequency control circuit 8, and brought close to zero, and the overcurrent is controlled. Reliability can further be improved by jointly using the lowering of output voltage and the reduction of the slip frequency at the same time as the overcurrent is detected in a high-frequency pulse-width modulation region.

IPC: H01F41/04
Filed: 1995-06-05
Abstract: PURPOSE: To eliminate dry plating or photolithographic technology by forming a board of ceramics and baking metal paste and forming a coil conductor. CONSTITUTION: After metal paste is spirally printed on a ceramic board 2 having low dielectric constant by screen printing, it is baked to form a coil conductor 3.

Thereafter, metal paste is screen printed on the batch 7, and baked to form a jump conductor 6. Then, an electric insulation layer 8 is so baked by using ceramic paste as to cover the conductor 3 and the conductor 6 to be formed on the board 2. Subsequently, terminal electrodes 9, 10 are formed at both ends of the board 2. Thus, dry plating and photolithographic technology are not necessarily used to form the coil conductor, and the low-cost coil conductor can be formed.

Title: Semiconductor laser array device
Inventor: SUGINO TAKASHI
IPC: H01S5/40
Filed: 1984-07-05
Abstract: PURPOSE:To stabilize single longitudinal mode oscillation, by forming cavities from the same composite cavities, respectively. CONSTITUTION:Grooves 9 are formed in the surface of an n type substrate 1 at equal distances. An n type GaAlAs layer 2, an active layer 3, p type GaAlAs layer 4 and a p type GaAs layer 5 are grown on the substrate 1. A stripe-shaped high resistance part is provided directly above the groove part 9, and ohmic electrodes 7, 8 are formed on the p-side and the n-side, respectively. A forward bias is applied between the P- and N-ohmic electrodes of the laser to oscillate a laser beam. Since each pair of adjacent stripes are close to each other, light is coupled between each pair of adjacent stripe-shaped flat portions of the substrate 1 to generate a laser beam consisting of in-phase light components. Since each stripe has a change in cavity configuration at the boundary between the groove portion and the flat portion, the light is internally reflected, and the reflected rays interfere with each other within each composite cavity, whereby stable single longitudinal mode oscillation is obtained.

Abstract: PURPOSE:To make compact and inexpensive a semiconductor device by a method wherein a photoelectric conversion element having a P-N junction and an active element used to amplify the electric signal generated in the element are integrated in one and the same semiconductor substrate. CONSTITUTION:A diode 1 used as a photoelectric conversion element and amplifiers 2-6 composed of the plural number of bypoler transistors 10 are formed in one and the same semiconductor substrate 11. In other words, N<+> type buried regions 13 and 14 are formed by diffusion on the surface of a P type Si substrate 11, and an N<-> type layer 12 is grown epitaxially on the whole surface of the substrate including the above regions.

Next, one layer 12b is used as a collector region where a P type base region 18 and an N type emitter region 19 located in the region 18 are formed to constitute an N-P-N transistor. On the other hand, a P type region 29 is formed by diffusion in the other layer 12a to make a diode 1. By so doing, it is possible to obtain a pickup with superior S/N sensitivity.

Filed: 1990-05-30
Abstract: PURPOSE:To reduce changes in display characteristics due to a change in an observing direction by setting up the refractive index of a phase plate in the thickness direction to a value larger than that in a direction vertical to an optical axis. CONSTITUTION:In a liquid crystal display device constituted of an upper side polarizing plate 1, an upper side substrate 5, liquid crystal molecules 7, a lower side substrate 8, a lower side polarizing plate 10, a backlight 12, and a phase plate 3, the refractive indexes of the phase plate 3 consisting of an optically compensating double refraction substance is anisotropically set up and the refractive index in the thickness direction is set up to a value larger than that in the direction vertical to the optical axis. Since the phase plate consisting of the double refraction substance, coloring of the background part and display part of the twisted nematic field effective type liquid crystal display element can be suppressed, and because the refractive index in the thickness direction of the phase plate 3 is larger than that in the vertical direction to the optical axis, a visual change in the display characteristics can be suppressed and effective display characteristics can be obtained.

Title: Controller for power-operated steering device
Inventor: MURATA MASUMI
IPC: B62D6/04
Filed: 1980-10-03
Abstract: PURPOSE: To enable to obtain a precise steering force and steering feeling suitable for all steering conditions, by a method wherein, through the addition of a power shift control to a control by car speed, a combination control is performed by a steering angle and a lateral direction acceleration speed.  
     CONSTITUTION: At the time of running at more than a middle speed, or if a rapid turn steering is conducted under the condition of less working oil amount, a steering angle speed sensor 10 works at an initial time of a turn steering, and the signal causes a control circuit 8 to change an energizing current to an electromagnetic solenoid 7. This moves a valve 2 so that the faster a turn steering speed is, the more working oil amount to a control valve 3 increases, which results in preventing a delay in a feed of a required oil amount. Meanwhile, a reaction force of a type T increases at the latter half of the turn steering, and this causes working of a lateral direction acceleration sensor 11. The signal enables the control circuit 8 to control the energizing current to the solenoid 7, and this allows the valve 2 to operate so that a working a oil amount reduces.

Thus, the circuit consists of a digital circuit. Then the circuit is stable against the fluctuation of power voltage and ambient temperature and the clock generator not requiring the period acquisition time till the clock is generated is obtained.
