Title: Vessel for pressure packing
Inventor: SAPAYAN EMU KURISHIYUNAKUMAA
IPC: B65D1/02
Filed: 1988-12-08
Abstract: PURPOSE: To maintain stress applied to container above prescribed value and to prevent the base part from being broken by equipping radial pentapod portion that concave head provided toward radial center of annular externals of base configuration has become pedestal and by separating the leg portion with radially expanding ribs. CONSTITUTION: In a structure of blow molded thermoplastic resin container with a large angle of expansion at the rib portion, thickness of the rib portion becomes large in the state with distribution in thickness in the direction of expanded angle and broadens width of the rib portion of the base 18. To obtain necessary strength for the rib portion, the leg portion 22 is made in five at most. Width Rw and thickness Rt of rib portion 26 become larger. Further, it is found further that the thickness Rt of the rib portion 26 is substantially larger than thickness Lt of the leg portion 22. This increase in thickness of the rib portion 26 reinforces strength of the base that receives a large pressure. Moreover, thickness of fillet portion 28 between each rib 26 and adjacent leg 22 also increases. The base whose shape was changed is made to have a larger durability against stress cracking.

Title: Rotation detector
Inventor: MIYAZAKI SEISHI
IPC: G06F3/0354
Filed: 1992-10-28
Abstract: PURPOSE:To provide the simple and economical structure of a rotation detector by rotating the rolls magnetized by multiple poles in response to the rotation of a global manipulator body and detecting directly the rotations of these rolls by a magnetic sensor. CONSTITUTION:A rotatable global manipulator body 1 is positioned at the opening part 9A of a printed circuit board 9. Then the rolls 2-5 which are magnetized by multiple poles are rotated by the rotation of the body 1. The rotations of the rolls are directly detected by the MR elements set opposite to each roll and then sent out as the detected signals on which the change of the electric resistance is reflected. For instance, the X direction components are directly detected and sent out by the MR elements set opposite to the rolls 2 and 4, and the Y direction components are directly detected and sent out by the MR elements set opposite to the rolls 3 and 5 respectively. Thus it is possible to detect the rotation of the body 1 by simple constitution where the rolls 2-5 are combined with the MR elements.

IPC: H01L21/316
Filed: 1992-11-20
Abstract: PURPOSE: To shorten high-temperature heat-treating time for removing minute gaps between silicon substrates in a welded junction method. CONSTITUTION: Silicon substrates W1 and W2 as the objects for junction after a general preprocessing step are arranged on a carrier 6 in a quartz pipe 1. Oxidizing agent (wet oxygen) is introduced into the quartz pipe 1 from a flask 10, and stabilizing process is performed under an oxidizing atmosphere. Then, after a primary junction has been performed, the carrier 6 is moved to the position of a heater 8. In the state, wherein the oxidizer atmosphere is maintained, heat treatment is performed for a short time (about 2-10 minutes). Thus, the growth of an interface oxidized film by the oxidizer supplied into the minute gap is introduced, and the removal of the minute gap and the reinforcement of the junction strength are achieved.

Title: Flow regulating valve
Inventor: NOKUBO SEIJI
IPC: F15B21/04
Filed: 1987-12-09
Abstract: PURPOSE:To prevent pulsation of a pump and to enhance the feeling of foot depression by pressing a piston when the viscous resistance of working fluid increases, so as to communicate first and second chambers through a cut-out part in order to regulate the flow rate of the working fluid. CONSTITUTION:When the frictional resistance of working fluid due to an orifice 3c formed in a communication passage which is formed piercing through a piston 3 provided in a valve body 2 movably overcoming a resilient means 8, increases upon low temperature operation, the piston 3 is moved by the increased resistance so that a flow passage between first and second chambers 4, 5 is established. Accordingly, the flow rate of working fluid may be regulated through a passage passing through the orifice 3 during normal temperature operation, but through a passage by way of the cut-out part 3d during low temperature operation. Accordingly, if this valve is used in a brake device incorporating antilock control, it is possible to eliminate such a conventionally experienced disadvantage that the flow of working fluid from a pump is ceased upon low temperature operation, thereby it is possible to prevent slight movement of a pedal due to pump pulsation, and to improve the feeling of foot depression.

Abstract: PROBLEM TO BE SOLVED: To enable to quickly move a case body matching with handle operation, by constituting the case body so as to transmit the operating amount of a means to operate the movement of a virtual vehicle directly to a case body movement mechanism to move the case body. SOLUTION: When a steering is steered, a first pulley 214 is rotated. Thereby a belt 222 is rotated to act rotation force in the same direction acts on a servomotor 220. On the other hand, the servomotor is constituted so that large rotation torque acts in the direction reverse to the steering direction to inhibit the rotation of the belt 222. It causes, when the steering is further rotated, the first pulley 214 to be rolled on the belt 22 in the reverse direction. At that time, a frame body 208 to support the steering shaft moves with the first pulley 214 to tilt a movable case body 200 in the direction reverse (outside arrow mark) to the steering direction (inside arrow mark) of the steering, Thus the handle operation amount can be quickly transmitted to the case body 200 through the belt 222 to move the case body 200.

IPC: G06F9/52
Filed: 1989-12-04
Abstract: PURPOSE:To eliminate the need for the monitoring job of an operator by providing a deadlock detecting function on the task control function of an operating system. CONSTITUTION:A task group control block TGCB 121 includes a task counter 1211 which shows the number of tasks that are started and not finished yet and a deadlock detection counter 1212 which shows the number of tasks of a practicable state or an executing state. Whether the state of the counter 1212 is '0' or not is decided, and when it is '0' it means that all tasks that are not finished yet are kept waiting and a deadlock state is detected for these unfinished tasks. In this case, the tasks kept waiting are never practicable again and therefore finished forcibly by an operating system. Thus the monitoring jobs of an operator can be omitted.

Filed: 1991-10-30
Abstract: PURPOSE:To attenuate, in improving the performance of a bypass mixing type hot-water supplying apparatus especially with respect to the resumption of hot-water supply, the sharp drop in the temperature of hot water that occurs when the supply of hot water is resumed. CONSTITUTION:In a supplying apparatus of the bypass mixing type, a mixing part BN at which the bypass 6, passed at a lower position than the heat exchanger 2, is connected with the channel 5 on the side of hot water is provided at approximately the same height as or at a higher position than the outlet CN of the heat exchanger. As a result, immediately after the supply of hot water has been stopped, it does not occur for cold water in the inflow channel in the cold water region and in the bypass to flow into the channel on the hot-water side, that is, into the hot-water region. Thus a temporary flush of cold water at the time of resumption of the hot water supply can be prevented and the performance of the hot-water heater at the resumed start of the supply is improved.
