Title: Cylinder injection type spark ignition engine
Inventor: NODA TORU
IPC: F02B17/00
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of NOx in stratified combustion by advancing the opening timing of one of two intake valves more than the opening timing of the other intake valve, setting a phase difference in opening timing between both the intake valves, and forming a valve recess in a position corresponding to one intake valve in a piston crown surface. SOLUTION: A phase difference in opening timing is set to intake valves 5A, 5B arranged in a first and second intake ports 7A, 7B, and the opening timing of the intake valve 5A is advanced more than that of an intake valve 5B. In a low load area where a stratified combustion is performed, the valve overlap between the intake valve 5A and an exhaust valve 6A is large, which actively increases the internal EGR quantity. A valve recess is provided in a position corresponding to the intake valve 5A in a piston crown surface, so that the injected fuel can be collided to the circumferential wall surface on the side having the valve recess by a swirl flow in the initial stage of the fuel injection to a cavity combustion chamber through a fuel injection valve 11 in stratified combustion to transfer all the fuel to an ignition plug 10 side by laying it on the swirl flow.

Title: Word retrieving device
Inventor: AKIYAMA SHIGEKO
IPC: G06F17/28
Filed: 1989-09-29
Abstract: PURPOSE:To reduce an access area and to shorten the retrieving time for an input word by retrieving the area which is specified by the first character of the input word with the second character of the word. CONSTITUTION:The character data inputted from an input part 1 are stored continuously in a data memory 5 until the input of the word punctuation data. When the word punctuation data is inputted, the words are retrieved. Then the first character of an input word is identified and an access is given to a big headline storage part 41. Thus the offset value of a crosshead storage part 42 is read out, and the second character of the input word is identified. An access is given to the second character from the offset position of the part 42 and the header of the code of the second character is retrieved. Hereafter the accesses are given to a subhead storage part 43 from the part 42 and to a semantic memory part 44 from the part 43 respectively. Thus the meaning of the input word and other information are read out and sent to a display part 3.

Title: Take-up device for veneer
Inventor: KOIKE MASARU
IPC: B27L5/02
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To prevent veneers from meandering and prevent their production yield during take-up process from lowering by outputting an operating signal to an interval changing member so that the interval between a magazine roll and all belts is widened when the radius reaches a specified level, and outputting an operation suspension signal to the interval changing member when the widened interval reaches a specified level. SOLUTION: A belt 4 is pushed down following the diametral increase of a rolled veneer and a piston rod 26a is slightly retracted into a cylinder tube. However, a force which the rolled veneer receives from the belt 4 is almost constant as the force to be brought about by an air cylinder 26 is almost constant. In addition, a force to act on a load cell is about 10% stronger than is a push-up force, so that a retaining base ascends resulting in the lifting-up of the rolled veneer. Consequently the piston rod 26a of the air cylinder 26 follows the ascending rolled veneer and protrudes. Therefore, the belt 4 continues to be brought into contact under pressure with the rolled veneer.  The veneer is taken up while it is brought into contact under pressure with the rolled veneer by the belt 4 and the pressure contact force of a touch roll 6 is constantly measured and controlled by the load cell, so that the veneer is not squeezed.

Title: Heat treatment method
Inventor: CHIYOU KOUYUU
IPC: H01L29/78
Filed: 1993-09-20
Abstract: PURPOSE:To solve problem of a glass base board shrinkage or deflection by holding the base board approximately horizontally, and heating it. CONSTITUTION:A reaction tube 11 made of quartz, a base board holding means 12, and a base board 13 arranged horizontally constitute a device for use with the heating processing method, which is further fitted with a heater for applying heat to the reaction tube 11 externally. A means to supply a certain gas to the reaction tube is equipped, and also a means to move the base board holding means to the outside from the reaction tube is furnished. The glass base board is held jorizontally for preventing it from deflecting and losing its flatness through a heating process. This configuration works effectively in the case which requires a process where a temp. over a distortion point is applied to the base board. If the base board is not to be shrunk in the heating process, it should previously undergo a heating process (pre-heating) to make a shrinkage so that shrinking in the later heating process is reduced.

Title: Laser cvd
Inventor: UESUGI FUMIHIKO
IPC: B01J19/12
Filed: 1984-12-05
Abstract: PURPOSE:To deposit a thin film having a desired width on a substrate by a laser CVD method by using a gaseous mixture composed of H2 and N2 for the carrier gas of an alkyl compd. and changing the mixing ratio of the gaseous mixture to change the decomposition temp. of the alkyl compd. CONSTITUTION:Laser light 12 is irradiated through a window 22 to the deposition part 13 on a substrate 11 on the surface of which the patterns of Si 20 and SiO2 21 intermingle to heat the substrate. The Al(CH3)3 transported by the gaseous mixture composed of gaseous H2 14 and gaseous N2 15 is decomposed and Al is deposited on the substrate 11. The substrate 11 and a cell 16 for deposition are slid on a stage 18 by a motor 19 so that the Al is deposited straightly. The mixing ratio is set at about H2:N2=1:1 and the total flow rate at about 700cc/min in the case of deposition on the Si 20 and the mixing ratio is set at H2:N2=1:9 in the case of deposition on the SiO2 21. The straight and uniform deposition of the Al at about 3mu width is thus made possible with substantially no change in the line width of the Al at the boundary line between the Si 20 and the SiO2 21 by changing the mixing ratio on the Si 20 and the SiO2 21 in the above-mentioned manner.

Abstract: PURPOSE:To properly follow to fluctuation in picking speed or unwinding time by comparing an average unwinding time for each unit turn with a response time of an engaging pin, selecting the optimum signal from plural unwinding signals outputted from each unit turn and outputting a stop signal to the engaging pin. CONSTITUTION:Weft yarn (Y) wound onto a drum (D3) is unwound and guided to a picking nozzle (N). In the process, unwinding time for each unit turn of the weft yarn (Y) is measured by an unwinding sensor (SA) composed of a light projector (SA1) and a light receptor (SA2) additionally attached to a ring member (B1) for mounting a balloon breaker (B) on the front of the aforementioned drum (D3). The average time of the unwinding time for each unit turn except at least the first unit turn is compared with a response time of an engaging pin (D4) to select the optimum unwinding signal from at least two or more unwinding signals raised for each unit turn so that the above-mentioned engaging pin (D4) may be present at the engaging position during a period from the time starting unwinding of the final unit turn to the completion time. Thereby, a stop signal is outputted to the engaging pin.

Title: Semiconductor device and its manufacture
Inventor: TAKAGI SHINICHI
IPC: H01L21/28
Filed: 1990-09-28
Abstract: PURPOSE:To reduce contact resistance between a semiconductor layer and a metal electrode, and improve characteristics of a semiconductor device, by setting the energy gap between the vacuum level and the valence band to be smaller than the energy gap between the vacuum level and the valence band of an Si layer. CONSTITUTION:A source.drain region 7 formed on a silicon substrate surface is in contact with a metal electrode 10, via dissimilar semiconductor such as germanium and silicon germanium alloy whose forbidden bandwidths are narrower than that of silicon. As the result, the heights of Schottky barriers of metal-dissimilar semiconductor and dissimilar semiconductor-source.drain region can be kept low. Further the effective areas of these materials are small, and the increase of a tunnel current can be expected, so that the contact resistance between the interfaces can be reduced. The mobilities of these materials are larger than that of silicon, so that the diffusion resistance also can be reduced. Thereby the parasitic resistance is reduced, the ON-resistance of a transistor is lowered, and high speed operation can be realized.

IPC: H02M7/12
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To achieve a compact configuration, light weight at low cost and to improve power conversion efficiency and the like by setting the power factor to the same degree with respect to the change in AC input voltage when a power supply circuit corresponding to a wide range is constituted. SOLUTION: A filter choke LN, a high-speed recovery-diode D2 and a controlled winding NR of an orthogonal control transformer PRT-2 are inserted into a rectified output line in series. A filter capacitor CN, which forms a low- pass filter together with the filter choke coil LN, is provided. The switching output is fed back to the rectified output line with a primary-side series resonance circuit (C1 , N1 ), and the power factor is improved. Then, the DC control current, which is decreased in correspondence with the rising of a rectified smooth voltage Ei, is made to flow through a control winding NC of the orthogonal control transformer PRT-2. Control is performed so that the power factor becomes approximately constant for the fluctuation of an AC input voltage VAC.  Thus, for example, a second series resonance circuit comprising the winding of a magnetic coupling transformer and a second series resonance capacitor is omitted.
