Title: Commutatorless motor for fan motor
Inventor: SATO HIRONOBU
IPC: H02P6/182
Filed: 1995-02-20
Abstract: PURPOSE:To make sure change-over of energization and stabilize rotation by providing stator wirings of three phases to the six pairs of teeth, always generating one nonenergized phase and supplying all powers in different phases for the teeth provided side by side to change over the energized combination of pairs of teeth on the basis of an induced voltage generated on the nonenergized stator wirings. CONSTITUTION:Stator wirings 20 to 25 are provided to teeth 14 to 19 of the six projected poles of a stator 13, a rotor 26 is magnetized in four poles and moreover the stator wirings 20 to 25 are coupled in three phases so that the teeth provided side by side are in the different phases and the teeth provides opposed with each other are in the identical phase during energization of three phases. All powers are supplied in such a pattern that only two phases among three phases are always energized and combination of the energized phases is changed depending on change of the induced voltage generated when the stator windings 20 to 25 are energized. Thereby, change-over of energization can surely be realized without using a rotating position detecting means such as a Hall element and moreover deviation of magnetic attracting force to the rotor 26 can be prevented and stabilized rotation of fan can be realized.

Title: Emergency shut-off valve
Inventor: EMA MASANORI
IPC: F16K17/36
Filed: 1982-03-02
Abstract: PURPOSE:To safely return a valve when a state of emergency is released, by providing a safety lock mechanism whereby movement of a valve body is restricted when a secondary pressure is exerted, and the restriction on the movement of the valve body is released when the secondary pressure is exerted. CONSTITUTION:When the state of emergency is released, an operating shaft part 28 is rotated to move a valve rod 32 against an elastic force of a spring 34, thereby leaking a pressure from a primary-side passage 3 into a chamber 15. In this case, when a cock is left unclosed, a lock shaft 21 receives the elastic force of a spring 23 and remains engaged with an engaging projected part 17a.  When the cock is closed, the pressure leaked into the chamber 15 acts on the interior of a diaphragm-operating chamber 24 through a through-hole 18d, whereby the lock shaft 21 is released from the projected part 17a. When the operating  shaft part 28 is subsequently rotated in the direction of an arrow F, a valve  port 5a is opened, and a plunger 7 is attracted onto an attracting element 12.

Title: Semiconductor integrated circuit device incorporating redundancy circuit for test
Inventor: SATOMI KATSUJI
IPC: G06F11/22
Filed: 1989-02-09
Abstract: PURPOSE:To insure the fast operating function of a synchronous logical circuit device by providing a DFF which inputs the external output signal of a synchronous logical circuit block and its synchronizing clock and outputting the output signal of the DFF. CONSTITUTION:The external output signal 38 from the synchronous logical circuit block 1 varies in synchronism with the leading (trailing) edge of the synchronizing clock S3 and is passed through circuits 2 - 6 incorporated in the block 1, so the signal varies while delayed by a propagation delay time. The DFF8 of the redundancy circuit uses a clock S3 as its clock signal. A signal S8 which is a data input at the timing where an edge of the clock S3 is inputted is data before variation by the DFF8, so the output signal S9 of the DFF8 holds the data before the variation until a next edge of the clock S3 arrives even after the output S8 varies by the propagation delay time later. Consequently, the signal level of the block 1 at fixed time and the signal level which is one cycle of the clock S3 before can be monitored at the same time.
