Title: Magnetic field generator for nuclear magnetic resonance imaging apparatus
Inventor: YOSHINO HITOSHI
IPC: G01R33/38
Filed: 1990-01-22
Abstract: PURPOSE:To obtain a stable image generating no strain or artifact by mounting the cylinder mounted on a yoke heel plate moving a movable member by the thermal expansion due to the change of atmospheric temp. of the liquid sealed in the cylinder. CONSTITUTION:When atmospheric temp. is changed in a state offset to either one of the upper or lower parts of a static magnetic field generator, the liquid 23 sealed in a cylinder 11 is thermally expanded and the force proportional to the diameter (d) of the cylinder 11 and the amount of the sealed liquid is generated corresponding to the degree of the thermal expansion to extend and retract a cylinder rod 11a and a movable member 9 is raised and lowered in a hole 24 only by the quantity following the change of atmospheric temp. and the uniformity change of a static magnetic field due to the change of atmospheric temp. is automatically adjusted. When the uniform change of atmospheric temp. is generated in the whole of the static magnetic field generator, the liquid 23 sealed in a cylinder 17 is thermally expanded to extend and retract a cylinder rod 17a and a yoke heel plate 10b is raised and lowered only by the quantity following the change of atmospheric temp. and the uniformity change of a static magnetic field due to the change of atmospheric temp. is automatically adjusted. Therefore, a stable image generating no strain or artifact is obtained.

Title: Synchronous clutch for multi-speed transmission for automobile
Inventor: AKUSERU DEIERU
IPC: F16D23/06
Filed: 1988-01-20
Abstract: PURPOSE: To prevent a locking tooth from entering in the cavity of a retaining tooth and a clutch tooth on the gear from wearing by seating the clutch tooth within the cavity, by making the width of a guide tooth narrower than that of the retaining tooth and the width of the first set of the locking teeth wider than that of the locking teeth of the second set. CONSTITUTION: At the time of an axial movement of a synchronous sleeve toward the gears, narrower guide teeth 6 and the second set of locking tooth 13 remain sliding in contact on the adjoining flat lateral surface and this contact prevents wider locking tooth 12 from being seated within the dent 8 formed on the lateral surface of the retaining tooth 5. When this sleeve is further moved axially, the sliding contact between the locking tooth 13 and guiding tooth 6 is maintained so as for the locking tooth 12 to go beyond the cavity 8 on the retaining tooth 5 and to allow interfering inner sliding contact between the surfaces of the locking tooth 12 and retaining tooth 5. Next, the gears rotate axially in relation to the sleeve to seat the clutch tooth 10 within the cavity 10 on the clutch tooth 10 and the guide tooth 6.

Title: Manufacture of starter yoke
Inventor: MORISHITA AKIRA
IPC: H02K15/02
Filed: 1982-01-26
Abstract: PURPOSE:To efficiently manufacture a starter yoke having excellent mechanical strength by forming a magnetically shielding groove by the pressing pressure of a roller. CONSTITUTION:A pressure receiving anvil 9 is inserted into the central hole of a cylindrical yoke 7 made of soft iron. A work which forms a magnetically shielding groove 8 on the outer peripheral surface of the yoke 7 presses a roller  6 from the outer peripheral surface of the yoke 7 toward an axial center, and  rolling the roller 6 in this state. The roller 6 has a structure that a disc of superhardness is rotatably journaled at the center, and is accordingly pressed to the outer peripheral surface of the yoke 7, thereby allowing the peripheral wall of the yoke 7 to hole it between the roller and the anvils 9, and forming the groove 8 having V-shaped cross section.

Title: Electrospark machining
Inventor: INOUE KIYOSHI
IPC: B23H1/02
Filed: 1978-02-01
Abstract: PURPOSE:When starting discharge after narrowing again the machining clearance widened for washing said clearance during the machining in which pulse groups and interruption intervals are made repeatedly, to stabilitze discharge by setting the continuances of said pulse groups to a large value and said interruption intervals to a small value. CONSTITUTION:The feed signals for narrowing the machining clearance once widened through the reciprocation of an electrode 1 for washing said clearance is detected from a control circuit 12, and thereby a counter 14 is cleared. Said counter 14 counts the clock pluses generated by an oscillator 15, controls to reduce a little the interruption intervals between said clock pulses as count increases so that said intervals are reset to the value initially set before reciprocation control, and makes said machining clearance properly fine for certain steady machining. After said clearance is narrowed, discharge is restarted with mean current density lowered by controlling to widen the interruption intervals between unit pulse rows and continued with said intervals reduced gradually to the initially set value thereof.

Title: Optical vehicle sensor
Inventor: KATO KENJI
IPC: G01J1/04
Filed: 1986-01-20
Abstract: PURPOSE:To improve the versatility of a sensor by structuring a lens system so that the lens system can shift in position to and away from a photoelectric converting element group for swinging and tilting. CONSTITUTION:The lens system 1' is so structured as to shift in position to and away from the photoelectric converting element group 2'. Consequently, the photoelectric converting element group 2' can be installed in parallel to a road surface 10 regardless of the fitting angle of the sensor. Then, the image formation surface 9 on the photoelectric converting element group 2' is parallel to the road surface 10, so A'1A'2/A1A2=B'1B'2/B1B2=h/H. Namely, magnification becomes constant regardless of the position on the road. Namely, photoelectric elements may be all the same regardless of the arrangement position. Therefore, the shape and position of the photoelectric converting element group 2' are determined by the magnification, in other word, only fitting height H and becomes irrelevant to the fitting angle of the sensor.

Title: Address conversion device
Inventor: NISHIMOTO TETSUNORI
IPC: G06F13/00
Filed: 1979-02-03
Abstract: PURPOSE: To avoid the loss the effective information on the TLB by removing space ID featuring the minimum number of the entry on the TLB from the STO stack in order to register the new entery to the STO stack.  
     CONSTITUTION: When the new entry is registered to memory 1 in TLB100, space ID is written into the address corresponding to memory means 3 with the contents of the address receiving +1. In case the effective entry is removed from memory 1, the contents receives -1 for the contents of the address in means 3 corresponding to space ID. And in case the contents of the segment base register varies, the ID featuring the minimum number of the entry on TLB100 is put onto register 23. Thus the number of the entry on the TLB100 of that moment emerges on register 36, and the entry of memory 2 emerges at register 27. Then the entry possessing space ID on register 23 is made ineffective on TLB100. After this, the contents of register 27 is shifted to register 25, and the contents of the new segment base register  emerged on line 36 is put to the corresponding entry.

Filed: 1989-01-19
Abstract: PURPOSE:To exclude the disconnection of an electric wire at a freely rotatable joint part and to enhance durability by receiving a power supply such as a dry battery in the arm constituting a fixation lamp apparatus. CONSTITUTION:The base stand 11 of an external fixation lamp apparatus is fixed to the forehead pad member 6' of the face receiving part of opthalmic machinery while a base stand support 13, an interruption arm 14 and an arm 16 having a battery 20 received therein are held in a freely rotatable manner and rotary friction force is applied to all of them by a friction adjusting screw 15. For example, the arm 16 is constituted of a light emitting diode 18, a switch 19 and a current limit resistor 27. Since it is unnecessary to pass an electric wire through a joint part moving a freely revolvable manner or to provide an electric contact, there is no possibility of the electrical disconnection in the joint part and a joint mechanism becomes simple and rotation over 360 deg. or more can be freely performed.
