Filed: 1991-07-31
Abstract: PURPOSE:To automatically select and output a status signal side, when a status signal is varied, in a state that a pulse signal side is selected and outputted by a variation of a pulse signal. CONSTITUTION:In a state that a first and a second flip-flops 3, 4 are set, a data selector 2 selects and outputs status signals S1-S3 by an output of an AND gate 9 and when pulse signals P1-P3 are varied in such a state, its varied pulse signals are latched by a latch circuit 1 by an output of an OR gate 5, and also, a second flip-flop 4 is reset, and the data selector 2 selects and outputs latch data of the latch circuit 1. Also, when a variation is generated in the status signals S1-S3 in such a state, pulse converting circuits 10-12 detect its variation, a second flip-flop 4 becomes a set state again by an output of an OR gate 8 passing through an AND gate 7 and an OR gate 6, and the data selector 2 selects and outputs the status signals S1-S3.

Title: Rice transplanter
Inventor: NAKAO YASUNARI
IPC: A01C11/02
Filed: 1994-09-08
Abstract: PURPOSE: To provide a rice transplanter capable of laterally transferring seedlings while suppressing the friction between the bed soil part of a mat seedling and the seedling stopper of a sliding guide rail of a seedling holding table. CONSTITUTION: The seedling stopper 16b of a sliding guide rail 16 of a seedling holding table is furnished with a sponge material 23a and a liquid-feeding path 23b. The liquid-feeding path 23b is connected with a chemical tank 25 via a chemical supplying channel 24 and liquid chemicals e.g. insecticide or disinfectant are supplied from the tank 25 with a liquid feeding pump 26. The sponge material 23a is impregnated with the liquid chemicals by supplying the chemicals through the liquid-feeding path 23b and a feeding hole 23c to the sponge material 23a. The chemicals are applied to the bed soil of a mat seedling A supported on the seedling holding table 11 by transferring the mat seedling in lateral direction while contacting with the sponge material 23a.  This process enables the insecticidal treatment and the sterilization treatment of seedlings and, at the same time, improves the slipperiness of the bed soil part on the seedling stopper 16b.

Title: Manufacture of semiconductor device
Inventor: NAKANO ATSUSHI
IPC: H01L21/205
Filed: 1983-11-15
Abstract: PURPOSE:To form a CVD film selectively in a simple and reliable manner by a method wherein a mirror film reflecting a light is connected on a semiconductor substrate and only a part removed of this film is heated when a film is formed by repor-phase growth (optical CVD) with the application of a light on the semiconductor substrate. CONSTITUTION:Using Al, an Al alloy, tungsten, molybdenum or the like as a material of a mirror film reflecting a light, a mirror film 2 is formed on a semiconductor substrate 1. A reactive gas is introduced into a quartz vessel through the inlet 4 thereof and exhausted to several Torr from the outlet 5 thereof. A light is applied onto the semiconductor substrate from the outside of the quartz vessel. On this occasion, a part to which the mirror film is connected reflects the light and is not heated, and thus a CVD film is not formed thereon. Consequantly, only the other part to which the mirror film is not connected is heated selectively, and thereby the reactive gas is decomposed pirolytically to form a CVD film 6. According to this method, a only necessary part of the semiconductor substrate is heated locally while the entire substrate is not heated, and this is very advantageous for a manufacturing process and reliability.

Title: Lead storage battery
Inventor: MURAKAMI HIDEHO
IPC: H01M10/10
Filed: 1983-11-14
Abstract: PURPOSE:To enable the captioned battery to be easily carried and reduce the ristriction in service side such as necessity of keeping said battery warm in a cold district, by impregnating positive plates, separators and negative plates with the electrolytic solution which is made by mixing diluted sulfuric acid, ammonium chloride and volcanic ash fine powder, and after making said battery to be in semi-dried condition. CONSTITUTION:Positive plates 1, negative plates 2 and separators 3 are sufficiently impregnated with the electrolyte which is made by mixing diluted sulfuric acid, ammonium chloride and volcanic ash fine powder. Thereafter, the liquid substance is removed and the impregnated bodies are made to be in semi-dried condition. By doing this, keeping a battery jar always to be horizontal is unnecessary and its portability is enhanced. Since there is also no possibility of leakage of the liquid, the battery can be set sideways. Furthermore, even it is used outdoors in a cold district, heat-retaining is unnecessary and the wire connection can be shortened, so materials and the cost of construction can be reduced.

SOLUTION: A pad-like oil coating member 14A is provided with a sponge 14Ab at its inside, and the sponge 14Ab is impregnated with oil, and composite film 14Aa where a porous texture material of about 50μm is impregnated and crosslinked with a material obtained by mixing silicone rubber with the oil so as to surround the sponge 14Ab is provided on a surface brought into contact with a fixing roller. Thus, the sponge 14Ab is impregnated with the silicone oil of a specified viscosity, so that the oil at the inside of the sponge 14Ab oozes out and is supplied to the fixing roller through the composite film 14Aa. The discharged quantity of the releasing oil must be the discharge equal to or above 0.6mg/page for the A4 sized OHT sheet. When it is <0.6mg/page, offsetting is apt to be caused.

Title: Shift lever
Inventor: KITO YASUO
IPC: F16H59/04
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To provide a shift lever wherein vibrations due to resonance are hard to happen and lateral rigidity is high. SOLUTION: A cylindrical attachment part 22 of a grip is attached to an upper end of a shaft 21 via upper/lower two rubber insert parts 28, 23. The upper rubber insert part 28, equipped with a bush 30 on an inner surface of a cylindrical insert rubber 29, is structured such that the shaft 21 can slide thereon axially. As a result, an axial spring characteristic of the upper rubber insertion part 28 can be unlimitedly lowered, and resonance is prevented by shifting a resonance frequency from a normal use frequency to a lower frequency zone.

Title: Pitching machine of high-speed rotative arm type
Inventor: TSURUTA TAKAO
IPC: A63B69/40
Filed: 1987-08-28
Abstract: PURPOSE: To simplify a structure and to use both overhand throw and underhand throw by one machine by diagonally attaching two curved arms to a disk for arm rotation, rotating them at a high speed and directly pushing out a ball by the arms. CONSTITUTION: When the arms 2 are rotated, a circular space is formed at a center part. When the ball is dropped there from a ball chute 6, the ball is moved between the two arms 2 along the arms 2 in the direction of the outer wall of a casing 1 by centrifugal force. At the time, the ball smoothly reaches the outer wall of the casing 1 without colliding with the outer wall of the casing 1 since the rotation of the arms 2 is fast. The ball is moved while being pushed by the arms 2 along the outer wall as it is and advanced to a ball control panel 4, horizontal shakes are eliminated and it is made to jump out from a ball exit 14 to the outside as it is. When the casing 1 is rotated for 180 deg. and fixed, the state of the underhand throw is changed to the overhand throw and use is performed for both underhand and overhand throws.

Title: Image reader
Inventor: ARAI KOJI
IPC: H04N1/04
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce color smear in an auxiliary scanning direction by constituting a means for reducing the centroid shift of a reading position in the auxiliary scanning direction of a plurality of line sensors, which is generated by the afterglow characteristics of the respective colors of a white light source for original irradiation, by means of hardware through the use of a pulse width modulation system. SOLUTION: The light control signal of a fluorescent lamp for original irradiation does not start control in synchronizing with the start-up of an Hsync period but executes control so that it is matched with a center reference. Even if the duty of the light control signal changes, a center position does not change. Thus, a start-up position is controlled to be variable in accordance with duty. The afterglow quantity of green and red is distributed to the front and the back of a light emitting area and they are averaged. Then, centroid shift quantity is reduced from d2 to fine d1. Thus, it can be set to a level which does not matter on the performance degradation of picture reading by line sensors at all.
