Title: Starting time fuel supply controller for internal combustion engine
Inventor: YOSHIOKA MAMORU
IPC: F02D41/04
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To detect a foreign object such as carbon or the like entering an intake valve and to eliminate the foreign object in the intake valve by washing it away with fuel injected from a fuel injection valve at the time of starting an internal combustion engine. SOLUTION: The determination of the entry of a foreign object in the intake valve 4 of an internal combustion engine is made by using an intake air quantity reduction ratio calculating means to calculate an intake air quantity reduction ratio based on an intake air quantity detected by an intake valve entry detecting means using an air flowmeter 21 and a cranking rotational speed detected by a rotational speed sensor 23, and then comparing this value with a specified value. If the entry of a foreign object is determined, the injection timing of a fuel injection valve 7 is set to be intake synchronous injection by a foreign object washing means, and the foreign object in the intake valve 4 is washed away by injected fuel.

Title: Ink removal device of printer
Inventor: HANIYU AKINOBU
IPC: B41F31/20
Filed: 1988-10-05
Abstract: PURPOSE:To prevent the deterioration of an ink scraping capability of doctor blade by providing a scraping tool arranged in such a manner that it comes in contact with a doctor blade when the doctor blade is away from a printing roll and a scraping tool drive device which rotates the scraping tool when the doctor blade is separated from a printing roll. CONSTITUTION:A doctor blade 4 is allowed to come in contact with an ink oscillating roll 1 to scrape sticking ink off the ink oscillating roll 1 with the doctor blade 4, and then the doctor blade 4 is separated from the ink oscillating roll 1 with a doctor blade movement device. Consequently, the doctor blade 4 comes in contact with a brush 12. Simultaneously, a drive motor 90 is driven to rotate the brush 12 and a doctor blade cleaning tool 8 shuttles back and forth along a direction where the doctor blade 4 extends. Then the brush 12 moves backward and forward along the doctor blade while rotating. Consequently, the ink is scraped off the ink oscillating roll 1 width the doctor blade 4, and then the ink remaining on the doctor blade 4 is automatically scraped off with the brush 12.

Filed: 1988-10-06
Abstract: PURPOSE:To secure a large hysteresis, and also, to execute comparison by using a value of a comparison voltage input as it is by feeding back a comparison signal output of a comparator through a diode and a resistance in series. CONSTITUTION:A resistance R1 is inserted into a line of a comparison voltage input VC of a comparator 1, and also, between the resistance R1 and the comparator 1, a comparison signal output VOUT of the comparator 1 is fed back through diodes D1-Dn of the anode side and a resistance R2 in series. When the comparison signal output VOUT of the comparator 1 is L, the diodes D1-Dn become OFF, and it can be compared with a signal input VIN between said input and the comparison voltage input VC as it is. Also, when the comparator 1 goes to ON once, the diodes D1-Dn become ON, and a voltage inputted to the comparator 1 is different from the comparison voltage input VC and generates a hysteresis. In such a way, when the comparator is OFF, the input signal and the comparison voltage input can be compared, and also, a sufficiently large hysteresis can be secured.

Title: Sampling of thin crystal or membrane
Inventor: YOSHIMURA HIDEYASU
IPC: C30B28/12
Filed: 1989-09-29
Abstract: PURPOSE:To permit all kinds of membranes to be sampled by a method wherein a thin crystal or membrane formed on the surface of a molten metal is brought into contact with a membrane sampling member maintained at a temp. higher than the solidifying point of the metal and lower than that of a liquefied substance, whereby the thin crystal or membrane is solidified so as to be attached to and sampled on the membrane sampling member. CONSTITUTION:When a liquefied substance is dropped onto the surface of a molten metal (silver) 11 developed into a flat form, a membrane M is formed rapidly on the surface of the metal 11 or a crystal is grown thereon, since the surface tension of the molten metal 11 is greater than that of the liquefied substance.

Title: Numerical value controller
Inventor: TAKEUCHI AKIHIRO
IPC: H02P5/50
Filed: 1991-10-01
Abstract: PURPOSE:To prevent deviation of a track due to a load change, etc., by comparing a current command to a motor with a predetermined set current, reducing a target speed if the command is larger than the set current, and regulating the command to each motor to the set current or less. CONSTITUTION:Current command comparators 28X, 28Y compare a current command to motors 10X, 10Y with a predetermined set current. As a result of comparison, if the command is larger than the set current, the command to the motors 10X, 10Y is regulated to the set current or less by a target speed regulator 30. Thus, even if tracking becomes difficult due to an overload, etc., the target speed is reduced. As a result, the tracking is secured, and a target locus can be drawn. Thus, a deviation of the locus due to the load change, etc., can be prevented.

Title: Method of improving withstand voltage strength of multilayer semiconductor device
Inventor: HANSUYOAHIMU SHIYURUTSUE
IPC: H01L29/32
Filed: 1990-09-21
Abstract: PURPOSE: To enhance breakdown strength of a multilayer semiconductor device by an arrangement wherein only the central region of the device is covered with an irradiation mask and the carrier life time is shortened through irradiation with charged particles only in the circumferential fringe region of a pn junction being biased. CONSTITUTION: Edge of a thyristor is cut obliquely at an acute angle starting from upper and lower major surfaces 9, 10, for example. Surface field strength is lowered in the region LBr on the circumferential fringe 12, 13 of a pn junction 7, 8 existing in the interface 11 on the side and the carrier life time is shortened through irradiation of electrons only in the region LBr on the circumferential fringe 12, 13. When the central region LBz of a semiconductor device is covered with an irradiation mask 15 made of a metal, for example, the carrier life time is shortened tram 200μs to 10μs only within the region LBr. Consequently, current amplification factor is also decreased within the region LBr and breakdown strength is enhanced in that region.
