Title: Cylinder block casting method and its cast product
Inventor: HASEGAWA YASUAKI
IPC: B22D19/00
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent the partial deformation of a preform in a cavity caused by the pouring pressure of molten metal without separately using a large-scaled suction apparatus or the like. SOLUTION: The cylindrical preform having a prescribed vol. ratio is fitted onto the outer periphery of a bore pin by being entagled with wear resistant metallic fibers. The molten metal is supplied into the cavity from molten metal supplying passages set in the forming positions of journal parts 3a-3e to constitute the inner peripheral surface portions of a cylinder bores with the preforms. In this way, the state the partial diameter-expansion deformation near the journal parts 3a-3e is caused in the preforms is prevented with a rigid member 21 fitted to the bore pin. The molten metal is allowed to be easily infiltrated by reducing the vol. ratio (enlarging porosity) only at the portion nearer to the molten metal supplying portion in the preform, thus the above mentioned deformation can be prevented. The preform is pressurized in the compressing direction with the molten mold pressure by slitting the molten metal supplying position so as to be positioned at the outer periphery of the preform, thus the above mentioned deformation can be prevented.

Inventor: PIEERU JIERUNE
IPC: G01N21/90
Filed: 1994-10-11
Abstract: PURPOSE: To prevent any premature outward exclusion of bottles from taking place by forcing bottles subjected to conveyer transport to pass an optical distance measuring device every time of their return, radiating light beams on the circumferential edge range on the bottle bottom parts from a measuring device and owing to the evaluation result of a distance measuring signal, bottles are separated and excluded outside of circulation process flow. CONSTITUTION: A laser distance measuring device 5 is installed at an interval to a pet bottle 1, light point is injected on the bottle 1 along an arrow mark A and reflected light beams are condensed in an image at a position sensor inside of the device 5 by means of an objective lens 4. The sensor inputs an analog signal proportional to a measured distance into an analytic device 6. The bottle 1 makes relative movement to the device 5 by means of a conveyer and the locus of a light point exceeds the base surface 2 on the bottle 1 and extends to the outside peripheral range of a dome 3 from the inside circumferential range of the base surface 2.  Two curves of a measured distance signal and a reflected light quantity signal are produced from the sensor output, and these are evaluated to detect rugged state and cracked state of the surface and any bottle 1 determined unsatisfied is removed and separated to the outside of the conveyer.

Title: Rolling piston type rotary compressor
Inventor: AEBA YASUSHI
IPC: F04C18/356
Filed: 1983-12-23
Abstract: PURPOSE:To uniformize clearances at both end surfaces of a piston and reduce the amount of leakage by a method wherein a slanted groove, located in the manner that the lower end opening is positioned in an advanced direction further than the upper end opening with respect to the rotating direction of a shaft and communicated with both end openings, is provided on the inner peripheral surface of the piston. CONSTITUTION:The inner peripheral surface of the piston 7 is provided with the slanted groove 31, located so that the lower end opening is positioned in the advanced direction than the upper end opening with respect to the rotating direction of the shaft 5 and communicated with both end openings. The piston 7 rotates with a speed slower than an eccentric pin 6 at all times, therefore, oil which flows on a sliding surface, collides against the slanted groove 31 and the flow thereof is curved as shown by an arrow sign 32 in the diagram. On the other hand, the oil receives a force shown by the arrow sign 33 as the reaction therefor, therefore, an upward component or a force in a direction to lift up the piston 7 is received by the oil as the component of the force shown by the arrow sign 33 as shown by the arrow sign 34 in the diagram. The upward component can be selected arbitrarily by changing a slant angle 35, therefore, the angle, in which the component 34 balances with the gravity of the piston 7, may be selected. According to this method, the clearances of both end surfaces of the piston 7 may be uniformized to reduce the amount of leakage and the performance coefficient of the piston may be improved.

Inventor: HIROSE TAKASHI
IPC: H05B3/48
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To provide uniform strength and an excellent mechanical characteristic of hardly causing a chip and a crack by ceaselessly winding/wrapping the whole circumferential direction of a core material in a state of forming a continuous layer by an insulating layer embedding a resistance heating element between the insulating layer and the core material composed of ceramics and being composed of ceramics for winding the core material. SOLUTION: A resistance heating element 13 and a terminal 14 are arranged on a surface of a ceramic columnar core material 11. An insulating layer 12 ceaselessly winds/wraps the core material 11 in a state of forming a continuous layer over the whole circumferential direction of the core material 11 for forming the resistance heating element 13 and the terminal 14. Thus, there is no easily chipping part in a ceramic heater 10, so that a crack is hardly caused. Since flexural strength of the ceramic heater 10 is uniformized in the circumferential direction, a mechanical characteristic is improved. In manufacturing the ceramic heater 10, a vertical directional cross section of a green sheet for the insulating layer is desirably an almost trapezoidal shape such as to satisfy an expression: (δ<=L-I<=4δ (L is the length of the lower bottom of a trapezoidal shape, I is the length of the upper bottom, and δ is a height).

Title: Multi-beam semiconductor laser driving device
Inventor: INOUE YASUAKI
IPC: H01S5/068
Filed: 1989-09-20
Abstract: PURPOSE:To keep an optical output unchanged by cancelling variations of the optical output caused by optical crostalk by adding part of the optical output from adjacent devices and entering it into a voltage comparator part for its comparison with an output from an optical output detector part. CONSTITUTION:Voltage generated from a reference voltage generator part 22 is denoted by V2, and optical output voltages detected by optical output detector parts 11, 31 of adjacent devices are denoted by V1 and V3. Assumed flowing currents through resistors R1-R3 to be i1-i3, a comparator input terminal voltage Vc of a voltage comparator part 23 is given: Vc-i2.R6+R6(i1+i3) with conditions R1, R3 R2, R6. First term of the right side of the above equation is voltage dependent on the reference voltage V2, and the second term is voltage dependent on the optical outputs V1, V3 of the adjacent devices. The comparator part 23 compares the voltage Vc and an output from an optical output detector part 21. When the adjacent device is supplied with power, the second term of the above equation becomes positive voltage and hence Vc increases. The amount of the increase of V2 can be adjusted by the resistors R1, R2. If it is set to be equal to the increased fraction of the optical detection output caused by optical crosstalk, laser output variations caused by the optical crosstalk are eliminated.
