Title: Junction type field effect transistor
Inventor: OGAWA KUNI
IPC: H01L29/06
Filed: 1977-12-16
Abstract: PURPOSE: To reduce recombination noises and 1/f noises by selectively forming a p-type gate, n-type source and drain which extend from a high resistance poly Si layer surface formed on a n-type Si layer to a n-type layer.  
     CONSTITUTION: The n-type layer 23 on p-type Si 21 is separated by p-type layer 22 and after high-resistance poly Si 27 is stacked, a high-temperature treatment is done in H 2  to improve the state of the interface between layers 27 and 23. Next, it is covered with film 29 through wet oxidation and an opening is provided selectively. By using Si 3 N 4  mask 31, layer 27 is etched at the opening part of film 29, and p-type gate 26 is made through B diffusion. At this time, p - -type layer is produced near the gate touching layer 27, so that noises due to lattice distortion through high-density diffusion will be reduced remarkably. In addition, since the center of layer 26 can be made into the P +  type, the series resistance will not increase. Further, film 29 has a contamination source and even if layer 26 touching film 29 is inverted partially into the (n) type, noises can be reduced low with a little influence upon layer 26. Mask 31 is removed, phosphorus is diffused to produce n-type layers 24 and 25, and an Al electrode is formed, so that a low-noise FET can be obtained.

Title: Method for aligning free-running frequencies of oscillators with each other by data bus control
Inventor: KENESU JIEI HERUFURITSUCHI
IPC: H04N5/44
Filed: 1995-06-19
Abstract: PURPOSE: To make it easy to determine and set a free-running frequency by calculating the difference frequency between the absolute values of a mean frequency and a reference frequency and applying a new control value to align a 1st oscillator with the reference frequency. CONSTITUTION: The free-running frequency of a timing generator 112 is aligned by an alignment device 800. To use the same alignment instrument for both a single-standard and a multiple standard type image receiver, the oscillator 112 is automatically adjusted by measuring a horizontal drive signal CHD representing a divided oscillator frequency. Spurious phase modulation is imposed on this signal CHD with blanking pulses obtained from another oscillator. Here, the mean frequency of a disordered signal is determined. After the mean frequency is measured, the frequency difference from the value of the reference frequency is calculated and represented as the absolute value. The absolute value of the frequency difference is tested for the value at the minimum end, e.g. 50 Hz, the oscillator 112 is synchronized again, and the alignment is completed.

Title: Orthogonal amplitude distortion correcting circuit
Inventor: TAKEDA YUKIO
IPC: H04L27/00
Filed: 1985-07-11
Abstract: PURPOSE:To eliminate orthogonal amplitude distortion by providing an amplitude operation device operating a difference of horizontal distance between a cross point of orthogonal axes as to each carrier and at least one set of signal points identified by a position identifier and using an output of the amplitude operation device so as to control the phase difference of the carriers to pi/2 thereby keeping always the axes of the carrier to pi/2. CONSTITUTION:An orthogonal amplitude modulated signal is divided into two by a hybrid circuit 1 and demodulated by a demodulator 2. In this case, the carrier obtained by a carrier recovery circuit 3 is used directly on one hand and used via a pi/2 phase shifter 4 and a phase shifter 11 on the other hand. The latter carrier is controlled so that the output of the amplitude operation device 10 has always a phase difference of pi/2 to one carrier for the phase shifter 11 fed via a low pass filter. That is, the phase difference of the carriers has an error (substantially the difference should be pi/2), it is identified and an output is obtained and the carriers are phase-shifted before the demodulator 2, then a normal signal is obtained always from the demodulator 2.

Filed: 1996-05-25
Abstract: PROBLEM TO BE SOLVED: To improve execution capability by providing a ring plate made of a synthetic resin or the like, which is attached to the bottom part of a cylindrical main body and includes a water expansion rein body integrally in its penetrated inner peripheral part. SOLUTION: After a cylindrical main body 1 is pushed into the head part required depth of an existing pile P, an anchor bar B is put through an attached part 41 and welded and fixed to a casing part in the upper surface of the existing pile P. Then, concrete milk is injected into the existing pile P, passed through a disk plate 3, a ring plate 2, a disk plate 3 and the bottom part of a cavity molding 1 and thereby the cylinder is filled with the concrete milk inside. Then, a water expansion resin body provided in the inner peripheral part of the ring plate 2 absorbs water contained in the concrete milk C and, since its upper and lower surfaces are held between the disk plates 3, expansion concentrates in the horizontal section direction of the concrete milk C passed through its inner peripheral part. Thus, the concrete milk part in the hardened part thereof is made thin and, by further absorption of water, cracks easily occur in the remaining concrete milk part.
