Title: Universal coupling of constant velocity
Inventor: KURIBAYASHI SADATOMO
IPC: F16D3/30
Filed: 1988-07-07
Abstract: PURPOSE:To make it possible to reduce its cost and provide it with proper constant velocity, by disposing a first arm and a second arm in mirror- symmetric relationship to each other within each of coupling units, and making the first and the second arms equivalent to each other in all the units. CONSTITUTION:An inconstant velocity universal coupling 26 a couples an end of the second portion 18a-2 of a first arm with an end of the second portion 24a-2 of a second arm, thereby to constitute a coupling unit. The first arm 18a and the second arm 24a are disposed in mirror-symmetric relationship to each other. The first arm is equivalent to the second arm, involving the relation between a driving shaft rotation counter 2' and the first arm and that between a driven shaft rotation center 4' and the second arm. It may thus be possible to reduce its costs and provide it with good constant velocity.

Title: Perishable fresh preserver
Inventor: TAJIKA TERUMITSU
IPC: A23B7/148
Filed: 1987-07-06
Abstract: PURPOSE: To store perishable articles for a long term by introducing carbon dioxide gas into a storage chamber upon elapsing a predetermined time after cooling it and increasing concentration of carbon dioxide gas while decreasing concentration of oxygen thereby lowering aspiration of the perishable articles in the chamber gradually. CONSTITUTION: A storage chamber 1 is cooled by a cooling unit 2 upon turning an operation start switch on and carbon dioxide gas is introduced into the chamber 1 from a carbon dioxide gas supply unit 7 upon elapsing 24 hours. Consequently, concentration of carbon dioxide gas increases while that of oxygen decreases. When the switch 9 is turned off, the units 2, 7 are stopped. Since aspiration of perishable articles is suppressed by increasing concentration of carbon dioxide gas or decreasing that of oxygen after aspiration is suppressed by cooling and settled, aspiration can be lowered gradually without applying any burden on the physiological action of the perishable articles.

Title: Manufacture of semiconductor device
Inventor: MATSUDA JUNICHI
IPC: H01L21/336
Filed: 1988-07-07
Abstract: PURPOSE:To control the positional relation of an S/D region accurately and an S/D region finely and to improve leakage current characteristics by forming the S/D region by self-alignment and taking care not to give distortion to a semiconductor substrate. CONSTITUTION:A sidewall 59 of polysilicon is formed in place of a conventional SiN sidewall, and after directly forming a field SiO2 film 10 leaving a thin SiN film 58 at this part, an S/D region 56 is formed between a gate and this field SiO2 film 10. For this reason, it suppresses generation of distortion at a semiconductor substrate arising from an SiN sidewall made of thin SiN film, which enables leakage currents at S/D region formation to be kept small, and the S/D region is formed in self-alignment. Hereby, the S/D region can be formed finely and in the same width.

Title: Picture processor
Inventor: SATO MAMORU
IPC: H04N1/393
Filed: 1985-08-02
Abstract: PURPOSE:To attain the conversion of pictures with high picture quality by giving the quick interpolation processing to the picture element data on the pictures obtained through a converting process based on the picture element data on an original picture in a production mode. CONSTITUTION:A result picture position register 45 advances synchronously with the picture signal pulse applied to an arithmetic circuit. Thus the result picture positions advance one by one. Here 'n' and 'M' are stored in a divisor register 42 and an increment register 43 respectively. Then the arithmetic circuit 41 divides the value obtained by adding 'M' to the values of both registers 42 and 43 and the picture element output 'm' set immediately before replacement by 'n'. Then a clock phi30 is delivered to advance the position of the original picture as long as the quotient is not equal to '0'. Thus an original picture position register 46 advances and therefore the original picture position also advances by one. Then the enlargement processing is through in the 1-dimensional direction and therefore the density of each picture element has the extremely smooth transition at sampling points after the end of said enlargement processing.
