Title: Color television signal generator
Inventor: AZUMAGUCHI HISAAKI
IPC: H04N11/24
Filed: 1987-06-15
Abstract: PURPOSE:To keep the continuity of a color signal between frames with simple constitution by switching a picture data outputted from a delay line corresponding to a phase difference of 180 deg. of a subcarrier and a picture data read out of a memory for each frame so as to output them. CONSTITUTION:A picture data sampling a color television signal while a sampling frequency CK is taken as 2N-multiple (N=1, 2,...) of the subcarrier frequency is stored in a frame memory 10, and when it is read repetitively from the memory 10 and displayed as a still picture, the picture data 101 read out of the frame memory 10 and the picture data 102 retarding the picture data 101 read out of the memory 10 by N samples corresponding to a phase difference of 180 deg. are outputted switchingly for each frame. Thus, the color phase is matched between frames with simple constitution and the continuity of the color signal is kept.

IPC: H04N19/50
Filed: 1995-06-14
Abstract: PURPOSE: To obtain a still image transmission system in which a transmission time being a required time or over is not required for an input image with a few changes. CONSTITUTION: An input image 103 is subject to discrete cosine transformation(DCT), quantization and conversion into variable length code sequentially in the unit of blocks for coding and the coded image is sent via communication line and the quantized data 106 are reverse-quantized and subject to reverse discrete cosine transformation (IDCT), and decoded and stored. In the process that difference data 104 between the stored decoded image 113 and the input image 103 are repeated for coding for plural number of times in the sequence above, when the data amount 201 converted into the variable length code reaches a prescribed value or below, the repetition of coding is finished and the succeeding coding of the input image is conducted.  Thus, when the input image is a precise image, number of times of repetition of the coding is increased and when the input image is rough, the number of times of repetition of the coding is decreased.

Title: Rotary head assembly for magnetic recording and reproducing device
Inventor: NAKATSU KIMIHIDE
IPC: F16C33/10
Filed: 1987-06-11
Abstract: PURPOSE:To prevent the damage due to the edge of a spiral group bearing in the radial direction by fixing an insert member formed with the spiral group on its inner circumferential face to a prescribed position of a rotary cylinder. CONSTITUTION:The insert member 11 is provided while surrounding a center shaft 3 and the spiral group 113 is formed in opposition to the center axis 3 in the inner circumferential face 112. Moreover, the insert member 11 is made of a material softer than that of the center axis 3. Thus, the center shaft 3 is not damaged by the spiral group 113 formed to the insert member 11. Thus, ununiformed film thickness of lubricant oil or ununiformed dynamic pressure caused in the spiral group bearing cause the vibration at rotation and a problem of baking the spiral group bearing due to oil film damage is solved.

Title: Power running control system of electric locomotive
Inventor: YANO TAMOTSU
IPC: B60L15/20
Filed: 1978-12-01
Abstract: PURPOSE: To perform the acceleration control smoothly by deciding whether the occasion is a starting case or a power rerunning case when the power running is commanded and by changing the speed of the notch step according to the decision result.  
     CONSTITUTION: The train speed detected by the speed generator 1 is compared with a reference value by the comparator 2, the relay LSRY is made off when the compared value is a fixed value or more. When the timer 3 is given a power running command, it produces a pulse of a fixed period, the period is longer when the  train is in power running of a fixed speed or less, and it is shorter when the power  running command exceeds a fixed value. The power running notch step-up circuit  4 counts the pulse of timer, and turns the power running notch command relay  N1RWN7R on in sequence. Thus, the power running notch step-up is commanded  by a pulse of a longer period to prevent a shock when the train is at a fixed speed  or less. In the case of power rerunning, a pulse of short period is commanded to  accelerate the train quickly.

Abstract: PURPOSE:To measure the length of a medium regardless of the skew of the medium by clocking the time detecting the medium by a sensor and the time between the times beginning to detect the medium by left and right sensors and calculating the length of the medium on the basis of the respectively clocked times. CONSTITUTION:Sensor parts 101, 102 are arranged to both side parts of a medium on the straight line in the lateral direction of the medium right-angled to the feed direction of the medium. The sensor parts 101, 102 output signals becoming 1 only during the passage of the medium between the positions of the sensor parts. A signal width measuring part 103 measures the times when the signals from the sensor parts 101, 102 are 1 at any time. A time lag measuring part 104 measures the time lag being the time from the point of time when the signal of the sensor part 101 becomes 1 to the point of time when the signal of the sensor part 102 becomes 1 or the time from the point of time when the signal of the sensor part 102 becomes 1 to the point of time when the signal of the sensor part 101 becomes 1. An operation part 105 performs operation on the basis of the measured results from the signal width measuring part 103 and the time lag measuring part 104 to calculate the length of the medium corrected in the error due to the oblique running of the medium.

Title: Preparing junction type field effect transistor
Inventor: YASUNO KOUSUKE
IPC: H01L29/808
Filed: 1978-11-29
Abstract: PURPOSE: To prevent withstand voltage property from deterioration by forming well through polycrystalline semiconductor formed on the semiconductor substrate.  
     CONSTITUTION: Polycrystalline Si 7 is formed on p-type Si semiconductor substrate 7. Using mask of SiO 2  8, etc., n-type impurity is selectively introduced to form n- well 9. Then, oxidation-inhibiting film 10 is selectively formed on the area which will later form the source, drain, and gate. This is oxidized at a low temperature to  form SiO 2 7' to allow the polycrystalline Si to be subdevided into 7a∼7c. Diffusion  mask film 11 is selectively formed on the surface of the area later becoming the gate. This is used for selective duffusion of n-type impurity through the film 7b, 7c to  form the source area 12 and the drain area 13. p-Type impurity is selectively introduced to the area to be later used as gate to form the gate area 14. Metal electrodes  15∼17 are formed on the areas 12, 13 and substrate 6. This permits high concentration area of n-well 9 surface to be located within the polycrystalline Si7 and thus is  effective in preventing withstand voltage reduction and capacitance increase.
