Title: Two cycle internal combustion engine
Inventor: ONO EIJI
IPC: F02B75/02
Filed: 1989-09-29
Abstract: PURPOSE:To prevent injection of quantities of compressed air due to deterioration of atomization of injection fuel and reduction in a pressure in a combustion chamber by a method wherein when fuel is injected in a combustion chamber from an air blast valve, the pressure of compressed air is increased with the increase in a pressure in the combustion chamber. CONSTITUTION:When a feed valve 5 is opened, the interior of a surge tank 12 is communicated with the interior of a combustion chamber 4, and a scavenging pressure in the surge tank 12 attains a value approximately equal to a pressure in the combustion chamber 4. In this period, a compressed air pressure fed to an air blast valve 21 is regulated to a value approximately 3kg/cm<2> higher than a pressure in the combustion chamber 4 by means of a pressure regulator 22. Thus, when, during this period, the nozzle of the air blast valve 21 is opened to inject fuel in the combustion chamber 4, since a compressed air pressure is always regulated to a value higher by a proper pressure than that in the combustion chamber 4, atomization of injection fuel is prevented from worsening due to an increase in a pressure in the combustion chamber 4, and quantities of compressed air is prevented from being injected in the combustion chamber 4 from the air blast valve 21 as a result of a pressure in the combustion chamber 4 being reduced.

Title: Partial curved surface dividing method
Inventor: KONNO TAKATSUGU
IPC: G06T15/80
Filed: 1991-09-30
Abstract: PURPOSE:To divide partial curved surfaces facing each other into plural patches with a high precision without generating a space by using the same division point on the boundary line of them to divide them into patches. CONSTITUTION:One boundary curve C1 on a partial curved surface as the division object is selected. Apexes on the selected boundary curve are denoted as division points of a first group. Parts between adjacent division points of the first group on the boundary curve C1 are divided by division points of a second group. Parameters whose values are 0 to 1.0 are given to division points of first and second groups. Points whose parameters approximate each other between sides facing each other are connected to form plural polyhedrons. When first division points are obtained, the density of first division points is changed in accordance with the radius of curvature of the boundary curve to obtain divided curved surfaces of high precision.

Title: Lead frame and method and metallic mold for molding semiconductor chip using it
Inventor: KOYAMA HISAKI
IPC: B29C45/26
Filed: 1992-09-22
Abstract: PURPOSE:To make the molding resin used for a resin sealed type semiconductor device to uniformly flow. CONSTITUTION:When an IC chip 8 is molded with a resin by forming dummy leads 6 between each inner lead 5 of the prior art lead frame, bending the dummy leads 6A and 6B upward or downward or alternately bending the leads 6A and 6B upward and downward, and injecting the molding resin by using a molding metallic mold 17, the flowing speed of the molding resin flowing along the inner lead section 5 is made nearly equal to that of the resin flowing above the IC chip and below die pads 3, since the leads 6A and 6B resist the flow. Therefore, the occurrence of voids due to the creeping of the molding resin flowing along the section 5 can be prevented.

Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To obtain a control apparatus which prevents the generation of harmonics at a frequency causing trouble, even when the operating number of a plurality of PWM converters connected to an AC power supply is changed. SOLUTION: The operating number of PWM converters 12, 22 is detected on the basis of the switching state of switches 11, 21 installed on the side of a power supply for the PWM converters. A carrier-frequency generation circuit 31 outputs a carrier signal at a frequency corresponding to the operating number. A maximum-current-limit-value generation circuit 51 limits the maximum current of the converters 12, 22, so as to correspond to the operating number (i.e., the frequency of the carrier signal). A selection circuit selects the carrier signal at a frequency corresponding to the operating number or a maximum- current limit value. Alternatively, a phase difference change and a selection circuit 62 selects the carrier signal at the frequency, corresponding to the operating number or the maximum-current limit value so as to give a phase difference to every carrier signal.

Filed: 1988-10-07
Abstract: PURPOSE:To prevent a punch-through phenomenon by providing an insulator in a semiconductor substrate over the entire surface of the same and specifying the depth of the insulator. CONSTITUTION:The title structure comprises a gate insulating film 3 and a gate electrode 4 laminated on a semiconductor substrate 6. An insulator 1 is provided in the substrate 6 over the entire surface of the same. The insulator 1 has depths thereof, one in a channel region being less than that corresponding to the thickness of an inversion layer, one in a source-drain region being deeper than the insulator 1 located in the channel region, and one at interface between the source-drain region and the channel region being continuously changed. Thus, a depletion layer formed at a P-N junction of a source-drain diffusion layer 2 does not extend to the channel section owing to the existence of the insulator 1. Hereby, a punch-through phenomenon can be prevented.
