Title: Two-stroke internal combustion engine
Inventor: SUGA TAKASHI
IPC: F02B75/02
Filed: 1990-04-18
Abstract: PURPOSE:To considerably improve charging efficiency by equipping an exhaust port and a cylinder scavenging port on the same side, and also providing a rotary valve, rotating so as to open the ports toward the upper side from the lower side, on a cylinder exhaust port. CONSTITUTION:Fuel is injected from a fuel injection valve 5 in the compression stroke of a piston 3, and is ignited with a spark plug 6 at the vicinity of a top dead center. An exhaust valve 8 is opened in the latter half of a combustion stroke to start the exhaust of a burnt gas from a combustion chamber 4. When the top part of the piston 3 is lowered from the position of a scavenging port 9 to open a rotary valve 11, fresh air from a supercharger 10 is pressedly fed, and the blowoff direction is gradually spiralled upward with the rotation of the rotary valve 11. Moreover an exhaust port 7, the exhaust port of the burnt gas, is located on the upper side of the scavenging port 9 on the same side to the cylinder center, consequently the introduced fresh air is returned to this side from a facing cylinder wall surface. As a result, the charging efficiency of the fresh air can be considerably improved.

Title: Clock generating circuit
Inventor: OOTA HIROSHI
IPC: H03K5/06
Filed: 1984-05-21
Abstract: PURPOSE:To adjust simply the length of logical ''0'' and logical ''1'' by giving logical ''1'' to the 1st input terminal of the 1st NAND gate, giving logical ''0'' to an input terminal of an inverting gate and connecting respectively the 1st and 2nd input terminals of the 2nd NAND gate and two of plural delay output terminals. CONSTITUTION:Explanation is made as to the adjustment that the period of logical ''0'' of an output waveform from an oscillator 1 is shorter than the normal value as shown in Fig. (a). A tap 10 and the 3rd connecting terminal 22, and the 6th connecting terminal and the 1st and 4th connecting terminals 20, 23 are connected respectively. Then, for example, a tap 11 and the 2nd connecting terminal 21 are connected. A signal [Fig. (d)] where the period of logical ''0'' is made longer is obtained at an output terminal 26 by ORing an output signal of the tap 10 [Fig. (b)] and an output signal of the tap 11 [Fig (c)] by the 1st three- input NAND gate 3. The period of logical ''0'' is made sequentially longer by changing sequentially the connected tap as taps 11, 12...19.

Title: Capacitor
Inventor: KITANO MOTOI
IPC: H01G4/18
Filed: 1987-04-24
Abstract: PURPOSE:To prevent an aluminum electrode film from deterioration or damages at its high voltage regions, by implanting ions of a dissimilar metal into the aluminum electrode by means of ion beams or the like. CONSTITUTION:An aluminum electrode is vapor deposited on one or both faces of an insulating polymeric film and then metallic ion are implantated from one or both faces of the film by means of ionic beams. By implantating dissimilar metal ions into the aluminum electrode in this manner, the aluminum electrode in an aluminum vapor-deposited film capacitor can be prevented from being deteriorated or damaged at its high voltage region, because the aluminum vapor-deposited electrode is modified by the ion doping or change in chemical composition thereof. The capability of preventing the aluminum electrode from deterioration or damages is dependent on the extent to which it is modified. The extent of modification is increased as an amount of implanted ions is increased but it is not dependent much on types of ions.

Abstract: PURPOSE:To decrease the interlocking frequency of a pipeline and to increase the executing speed of an object program, by performing the instruction scheduling in a conversion mode in consideration of an instruction group to be carried out between blocks immediately before and after the block. CONSTITUTION:The object code converting part 23 of a compiler 2 converts the intermediate text groups 61 and 62 included in an intermediate text 6 into object codes 71 and 72 in consideration of the instruction group to be carried out immediately before and after a block. In other words, the instruction defining a register SO contained in a code 71 is shifted to the position before the instruction which does not define the register SO that is practicable after the instruction which defines the register SO via the instruction scheduling process since an instruction using the register SO is included in the instruction group contained in the block to be executed immediately after the instruction. In the same way, the instruction using the register SO contained in the code 72 is shifted to the position after the instruction which uses no register SO since the instruction that defines the register SO is included in the instruction group contained in the block to be executed immediately before the instruction.

Title: Production of alumina powder
Inventor: YAMADA KOICHI
IPC: C01F7/145
Filed: 1986-05-02
Abstract: PURPOSE:In producing alumina powder by Bayer's process, to obtain uniform, fine alumina powder inexpensively, by adding alpha-alumina powder as a seed to an alkali aluminate solution and precipitating aluminum hydroxide.

The amount of the alpha-alumina powder added is properly about 0.1-50pts.wt. based on 100pts.wt. aluminum hydroxide to be precipitated. Then, the precipitated aluminum hydroxide is filtered off, dried and calcined to give the aimed alumina powder. Consequently, when aluminum hydroxide is calcined and transformed into alpha-alumina powder, the aluminum hydroxide can be calcined at relatively low temperature in a short time and calcination cost can be reduced. Fine primary particles can also be obtained and alumina powder having small average particle diameter and narrow particle size distribution after grinding can be obtained.
