Title: Spindle controller of machine tool
Inventor: USHIGOE TOMIO
IPC: B23Q5/20
Filed: 1982-09-03
Abstract: PURPOSE:To index a main spindle without causing any necessity for additionally providing a control shaft, which controls a rotary angle of the spindle, by providing an indexing plate having grooves divided at an equal distance on the peripheral position of the spindle and indexing the spindle by inserting a rotary knob provided on a tool rest into the divided groove, in the case of a spindle index controller of a machine tool. CONSTITUTION:A workpiece held by a main spindle is subjected to turning work by a rotary tool 15 and turning tool 14 on the first feed slide bed A. Next, if a Z-axis slide 9 of the second feed slide bed B advances along a rotary shaft line of the spindle to a position, where a rotary knob 18 of a control member 17 is enaged with the divided groove on an indexing plate on the spindle, the Z-axis slide 9 stops. Thereafter, an X-axis slide 10 of the second feed slide bed B advances the workpiece by the distance corresponding to the amount of travel required for machining a prescribed long hole toward the rotary shaft line of the spindle. Thus the spindle is able to give the workpiece a necessary rotary feed and further index the workpiece.

Title: Method and device for polishing
Inventor: UEDA SHINJIROU
IPC: B24B31/02
Filed: 1982-09-03
Abstract: PURPOSE:To enable increase in rotational speed when the angle anf frequency of inclination are increased by providing a rotary motion to a polishing drum while combining with it an axially inclining motion in which the angle of inclination or rotary shaft, amplitude and vertical amplitude ratio are freely selectable. CONSTITUTION:Workpieces, together with 50 to 60vol% of abrasives, water, compounds, are filled into a drum 1 through the opening 2, and a rotary shaft 4 and a shaft 20 are rotated through a drum 1 rotating motor 8 and a base- seat inclining motor 23. The drum 1 is rotated through the shaft 4, while the rotation of the shaft 20 allows eccentric wheels 18 and 19 to eccentrically revolve leading to relative vertical motion of rollers 16 and 17, which, in turn, causes the right-left inclining motion of the base seat 7, resulting in the right- left inclining motion of the drum. Therefore, if the drum is rotated at high speed when the angle and frequency of inclination are increased, the device is not subjected to non-polishing condition because of centrifugal force, continuing highly efficient polishing operation due to the combination of rotating and inclining motion of the drum.

Title: Plate connector
Inventor: MORINO GIICHI
IPC: E04B2/74
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To allow an easy connection with plates both horizontally and vertically by forming, at both ends of a planar plate, side plates which can be fitted into a frame, and placing on the side plates a pair of slightly projecting locking pieces each having a notched part that is not shorter than the sum of the widths of two frames. SOLUTION: Side plates 1b are installed in such way as to form an almost U-cross section so that the frame of a plate can be fitted to both ends of a planar plate 1a. Locking pieces 3a, 3b which project slightly to both sides of a notched part 4 are placed on the side plates 1b, the length of the notched part 4 being not less than the sum of the widths of two frames. The side plate 1b of this connector 1 has elastic action whereby it can be opened slightly to the planar plate 1a when mounted on a plate. To connect plates together, the connector 1 is inserted into their abutting parts, and the locking pieces 3o of the connector 1 are opened by the elastic action, attaching the frames of the plates to the notched parts 4.  Thus the opposite locking pieces 3 lock to a lower ridge while sandwiching the frame, and prevent horizontal movement of the connector 1, so that the plates can be firmly and easily connected together.

Title: Test circuit arrangement
Inventor: BEIER RALF
IPC: G01R31/02
Filed: 1995-06-21
Abstract: PURPOSE: To provide a test circuit having a comparator connected to a circuit point to which a test current is fed from a current source, for comparing a voltage at the circuit point with a reference voltage so as to detect an excessive leakage current at a high impedance circuit point at a low voltage and at a high speed. CONSTITUTION: A circuit point P1 is connected to one of input terminals of a comparator K1 and a reference voltage Ur1 is connected to the other one of input terminals of the same. The reference voltage is produced by a voltage divider between, for example, UB and 0V, and is substantially equal to a half of an operating voltage. As far as the leak resistance RL is sufficiently high, and accordingly, as far as the leak current IL is sufficiently small, the voltage at the circuit point P1 is higher than the reference voltage Ur1 so that the comparator K1 produces a low output signal.  The leakage resistance RL becomes lower than an allowable tolerance, and accordingly, the voltage at the circuit point P1 becomes lower than a reference voltage Ur1 when the leakage current IL exceeds a test current I1 and accordingly, the comparator K1 produces a high output signal which indicates that the leakage resistance is excessively low.

Title: Low temperature tank linked its suspended roof with loops
Inventor: NIWA RIICHI
IPC: F17C3/02
Filed: 1978-12-15
Abstract: PURPOSE:To prevent a tank, its suspended roof from breakage by linking the suspended roof and the tank bulkhead endlessly with loops of catenating rope materials. CONSTITUTION:A suspended roof 4 is provided at the upper side on the liquid level in such a way that endless ropes 5 are linked with loops of eye hardwares 6, 7 respectively installed on the inside of the tank 1 and on the verso side around the rim of the suspended roof 4. Thus, in case where horizontal external force is worked on the suspended roof 4, suspending rods 3 are easily applied flexure owing to their ratio of height to length, so that the suspended roof 4 is ready for swinging like a pendulum. In consequence, the swing is hindered by tension of the rope on the opposite side to be ready for swinging. In this event, the rope 5 made of twines has high percentage of elongation, so that energy is fully absorbed by the elongation. Since this prevents efficiently swing in such a way that the rope for half a month on the opposite side of the swing entirely participates in the absorption of swinging energy, and prevents efficiently the swing, breakage of the tank, etc. can be prevented.

Title: Electrode catalyst for fuel cell
Inventor: KOSEKI KAZUO
IPC: H01M4/96
Filed: 1988-06-23
Abstract: PURPOSE:To more promote activation to obtain an electrode catalyst layer having a good polarization characteristic by decreasing a quantity of the fine grains of fluororesin as water repellent material to a quantity necessary for binding taking advantage of the water repellency of acetylene black. CONSTITUTION:A fine grain of catalyst 7 and a fine grain of acetylene black 8 are bound by a fine grain of fluororesin 3. A water repelling action is made by the fine grain of acetylene black 8 and the fine grain of fluororesin 3. The purity of the fine grain of acetylene black 8 is high and does not have a group having electrolyte and affinity (e.g., carbonyl group, carboxyl group, aldehyde group, etc.) on the surface. Its water repellency, therefore, is higher than the other carbon carriers. This water repelling action makes it possible to reduce fluororesin as water repellent material and therefore, the degree that a fine grain is covered with fluororesin decreases and the electrode catalyst can be more activated than before; as a result, it is possible to obtain an electrode catalyst layer for fuel cell having a good polarization characteristic.

Title: Out-of-step detecting device
Inventor: NAKANO AKIRA
IPC: H02H7/06
Filed: 1994-07-07
Abstract: PURPOSE:To use a standard A/D conversion circuit for an out-of-step detecting device by eliminating the need of using exclusively circuits for detecting out-of- step by A/D-converting voltage signals at every sampling time of voltage signals which are sampled at one-sampling intervals and transmitting angle information obtained by calculating phase angles from a prescribed operational expression for phase. CONSTITUTION:Voltage data sampled from the voltage waveform 2 of a B- terminal station at one-sampling intervals (30 deg.) are A/D-converted at every sampling time. When both preceding data V1 and this-time data V2 are positive or negative, 30 deg. phase information is transmitted. When the preceding data V. are negative and this-time data V1 are positive, phase information theta calculated from the number '1' of a prescribed operational expression for phase is transmitted. When the preceding data V6 are positive and this-time data V7 are negative, phase information theta calculated from the number '2' of the prescribed operational expression for phase is transmitted, where theta2=tan<+>V7/(sq. rt. 3 V7-2V6), V7=Vsin(theta2+180 deg.) and V6=Vsin(theta2+150 deg.). Therefore, such an exclusively used circuit as the rectangular wave generating circuit for detecting out-of- step, panel number quantizing circuit, etc. becomes unnecessary.
