Title: Variable capacity type pump
Inventor: NAKAMURA KIYOUICHI
IPC: F04C14/22
Filed: 1983-11-18
Abstract: PURPOSE:To make it possible to control the flow rate and the pressure of a vane pump with a single member by providing an orifice forming member, which divides the fluid passage into two parts, between the cam ring and the housing and by providing a spring at one end of this forming member and leading the discharge pressure to the other end of it. CONSTITUTION:Between a cam ring 14 and a fixed ring 12, an orifice forming pin 32 is placed in parallel to the axial line of a rotor 17, and a spring 35 is set, at one end of the pin 32, between a hole 10a and this end. Also at the other end of the pin 32, the orifice pores are provided to divide a pressurized fluid passage 15 into working chambers 15A and 15B.

Title: Method and apparatus for determining electric modulus of pipe
Inventor: JIYOSEFU DEIBUIDO TEITOUROU
IPC: G01N29/04
Filed: 1988-09-02
Abstract: PURPOSE: To determine a coefficient of elasticity accurately and easily by measuring the length and density of a pipe, exciting stress wave at one edge of the pipe, and subtracting a specific coefficient from a propagation time where a stress wave is propagated to the other edge of the pipe and obtaining a correction propagation time. CONSTITUTION: An acceleration meter 14 is fixed to the head part of a hammer 12, caps 18 and 22 are sealed to both edges of a pipe 20, and an acceleration meter 24 is sealed to the cap 22. When the head part of the hammer 12 strikes against the cap 18, stress waves are generated, the acceleration meter 14 generates an electrical pulse, and a circuit 16 detects it, thus starting clocking operation. The cap 18 enables the stress waves to enter the pipe 20 relatively uniformly and to be propagated within the pipe 20 along the pipe 20 easily. When the wave front line of P wave of the stress waves arrives at an edge part 34 of the pipe 20, it is transferred and propagated from the pipe 20 to the cap 22 and the acceleration meter 24 detects it and operates an electrical pulse to the circuit 16, thus stopping clocking operation.  The circuit 16 corrects delay due to the caps 18 and 22 and the acceleration meter 24 and determines a correction propagation time where the P wave is propagated from one edge 34 to the other of the pipe 20, thus obtaining the Young's modulus of the pipe 20.

Filed: 1988-09-02
Abstract: PURPOSE: To provide a tensioning device which is simple and not bulky and is suitable for the use together with a safety belt for passenger by constituting in such a way that an air storage tank forms a part of inertia mass in the tensioning device including a speed change response means. CONSTITUTION: An air storage tank 2 is pushed to the right by force of an ordinary spring 19. In case of extreme deceleration of a vehicle, for example, an accident including collision, the air storage tank 2 forms a part of a speed change response means and moves to the left in a housing 5 against the spring 18 as a result of its inertia force. When the air storage tank 2 performs a motion of about 1 to 2 mm, stored pressure medium is immediately released to act on the whole operation surface 25 of a piston member 28, the action of gas is increased by about 10 times, and the piston 28 is speedily driven to the left to move a tensioning cable 13. A ratchet device formed by a claw 4a and a rack 4 keeps a safety belt in a condition in which it is stretched fully and tightly. Consequently, it is possible to obtain a tensioning device which is simple and is not bulky.

IPC: H01L21/265
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To obtain the effect of channel stopper implantation without providing any additional masking process by thermally forming oxide film areas which demarcate an active area and doped areas of a first conductivity in a wall area. SOLUTION: Combined doped areas 62 are spread at a certain distance under field oxide film areas 38 and 39, especially, under parts of bird's-beak zones 64. The thicknesses of the areas 38 and 39 fluctuate in the bird's-beak zones 64 of the areas 38 and 39. Therefore, in the areas where the zones 64 reach the full thicknesses of the areas 38 and 39, field implantation 130 is nearly completely masked. Therefore, such a self-aligned field implantation structure that the combined doped areas 62 are only formed in the area of a p-well 12 which is not masked with the areas 38 and 39 is formed, because the field implantation is self-aligned with the edges of the areas 38 and 39.

Title: Method and device for forming groove on outside peripheral surface of shaft to be rolled
Inventor: TAKEKOSHI MIKIO
IPC: B21H7/18
Filed: 1988-09-05
Abstract: PURPOSE:To curtail the set-up manhour without necessitating to consider a relative position relation of a groove alignment, etc. by pressing one piece of groove form rolling roll and one piece of plural pieces of smooth profile rolls having no groove shape against the outside peripheral surface of a form rolling shaft and giving them a rotation. CONSTITUTION:At the time of forming a groove on the outside peripheral surface of a form rolling shaft, by one piece of grooved form rolling roll 1 and one piece or plural pieces of smooth profile rolls 4 having no groove shape, the respective rills form a groove on the outside periphery of the form rolling shaft, while executing a profile rotation. Accordingly, since there is no groove in one profile roll 4 of plural rolls, it becomes unnecessary to consider a relative position relation of a groove alignment, etc., and the ste-up manhour is reduced remarkably. In this regard, it will suffice that the profile roll 4 and the form rolling roll 1 are synchronized separately with the outside periphery of a form rolling object, a mechanism for synchronizing the rotation of a die is not required at all in the device, and the device itself is simplified in its structure, and also, miniaturized.
