Title: Structure of combustion chamber for direct injection type diesel engine
Inventor: SAKURAI NORIYUKI
IPC: F02B3/06
Filed: 1986-10-23
Abstract: PURPOSE:To enable the air flow within a combustion chamber to be changed into a turbulent flow uniformly and effectively while it is efficiently confined therein by providing the opening of the combustion chamber in such a manner that it has a lip protruding inward in the radial direction. CONSTITUTION:The opening 4 of a combustion chamber 2, which is provided on a piston head 1 in such a manner that it is sunk in the piston head 1, is displaced into a figure similar to the bottom part 3, and in the circumferential direction with respect to the bottom part 3 so that a lip 7 is formed. Hereby, the air flow introduced into and confined in the combustion chamber 2 can be easily changed into a turbulent flow by way of varying the quantity of overhang of the lip 7 along the circumferential direction of the combustion chamber 2. In addition, it is designed that the air flow produced within the combustion chamber 2 can be confined efficiently therein by allowing the lip 7 to be formed into the shape of convex curved surfaces 5a, 5b inward in the radial direction of the combustion chamber 2. Thereby, promotion of changing fuel into mixture and improvement of the air utilization factor can be achieved.

Title: Variable multiplier circuit
Inventor: MASUBUCHI SHINICHI
IPC: H03K4/00
Filed: 1985-11-11
Abstract: PURPOSE:To easily set a desired number of multiple by multiplying a frequency signal supplied from other input of transistors (TR) connected as a differential pair according to the characteristic decided by the current being sum of reference currents. CONSTITUTION:Many differential pairs are constituted with TRs Q11-Qn and collectors of the TRs Q11-Qn are connected in common to load resistors R11, R12. As to a constant current circuit CS, the circuit connected by resistors Re1-Rer has the same current, but the current of constant current circuits CS11, CS12, for example, is different. Then the current IA flowing to the resistor R11 is the sum between the currents flowing to each TR at the supply side of an input signal Vin and the supply side of a reference voltage Vref1. Thus, in supplying the signal Vin, an output signal Vout multiplied by N times is obtained and a desired number of multiplication is easily set by adjusting the number of the differential pairs.

Filed: 1992-09-21
Abstract: PURPOSE:To provide the instruction form change device saving the memory capacity with high efficiency of program preparation. CONSTITUTION:An instruction containing a direction code to direct membership function shape information is changed to a middle form by an instruction shape change means 5. A display means 4 accepts it and displays the direction code included in the instruction and the keyword group of the membership function shape information stored in a membership function information storage means 9. When an operator inputs the selected keyword group, a membership function information readout means 10 reads out the membership function shape information stored in the membership function information storage means 9 based on this. An instruction synthesis means 7 replaces the direction code of the instruction changed by the instruction shape change means 5 with the read membership function shape information, further synthesizing the instruction containing the membership function shape information.

Abstract: PURPOSE: To prevent a change into a useless state of a lawn even when a car passes by laying blocks formed by continuously connecting short cylindrical bodies on a ground surface while coupling irregular sections formed to the outer circumferences of the blocks, charging soil into the short cylindrical bodies and planting the lawn. CONSTITUTION: A large number of hexagonal cylindrical bodies 2 consisting of high- density polyethylene are connected continuously, thus forming a honeycomb block 1. Notches 3 are formed at the upper ends of the walls of the adjacent hexagonal cylindrical bodies 2. Circular openings 4 for drainage and the spread of the roots of lawns are formed to the bases of the hexagonal cylindrical bodies 2. Projections are formed to the bases of the blocks 1 while one opposed surfaces are formed in a trapezoidal irregular shape and the other opposed surfaces are formed in a triangular irregular shape in the outer circumferential sections of the blocks. The projections 5 are pierced into soil to fix the blocks 1 onto a ground surface, and earth brought from another place and mixed in soil is charged into the honeycombs of the blocks 1.  The whole surfaces of the soil covered with the lawns and the lawns are contact- bonded. Accordingly, even when a car passes on a top face, into which the lawns are planted, irregularities are not formed in the ground surface, thus preventing the damage of the lawns.

Title: Toothbrush
Inventor: RIN SEN HOTSUKU
IPC: A46B11/02
Filed: 1989-09-27
Abstract: PURPOSE: To control distribution of tooth paste simply and effectively by moving a distributing part, when it is pushed to a first direction, to a sealed surface being engaged with a part so as to distribute tooth paste from a chamber. CONSTITUTION: Tooth paste is prepared in a chamber 8, and a distributing part 16 fills up the chamber 8 in the axial direction to press a pole 15 along the chamber 8. A finger 20 of a member 18 is engaged with the pole 15, and the distributing part moves together with the pole 15 along the chamber 8. Movement of the distributing part 16 pushes the tooth paste in the chamber 8 to a pipe 7, then to the brush head. When the cap 4 is released, a spring 14 pushes the cap 4 back to its original position and pulls the pole 15 back to its original position. An elastic finger of an elastic member 18 leaves the pole elastically for a moment to allow the raised part to pass in a distributing part 18 without moving from its displaced position in the chamber 8. In order to get enough tooth paste from a distributing tube 6, the cap 4 is repeatedly pushed and released.

IPC: B60K5/12
Filed: 1985-11-12
Abstract: PURPOSE:To effectively prevent an increase in dynamic spring constant of a vibration control equipment for high-frequency small amplitude vibration by forming a subsidiary liquid chamber on a partition wall for dividing into two liquid chambers, dividing an adjacent portion to both liquid chambers by a flexible film. CONSTITUTION:An incompressible liquid such as water is enclosed in the whole of a closed chamber 11, and the chamber is divided into two liquid chambers 13, 14 by a partition wall 12 provided wit a throttle passage 15. A subsidiary liquid chamber 21 where a required liquid is enclosed is formed by rubber films 17, 18 adjacent to the liquid chambers 13, 14. In this arrangement, vibration transmitted to a frame 2 is, if it has low-frequency and large amplitude, damped by internal friction of an elastic member 3 and fluid resistance and liquid column resonance of a liquid passing the throttle passage 15. On the other hand, high-frequency small amplitude vibration is insulated by deformation of the rubber films 17, 18. Accordingly, such vibration having contrary characteristics can be effectively damped and insulated to prevent an increase in dynamic spring constant effectively.

The data subject to shading correction are given to a position error measurement section (circuit) 4, which provides an output of an error signal 6 in response to the measurement result.  The position error measurement section 4 dinarizes the image data with the pattern and sets a window sequentially to the data after threshold processing to obtain a position of the image is oblique lines in the window.
