Title: Door opening/closing detecting device and jig used therefor
Inventor: OKUBO HIROYUKI
IPC: E05F7/00
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To improve safety with inexpensive structure by switching a shutter, energized onto an action block position of a detecting switch by a protruding part of the other door, into an unblock position at the time of closing one door of a double-leafed hinged door. SOLUTION: In the opened state of a double-leafed hinged door, a shutter 7 is in a block position, and a switch 4 is in an off state. When one door is closed, a protruding part comes in contact with a block part 7a of the shutter 7 and cannot enter further into protective cover 3 so as not to result in putting the switch 4 in action. When the other door is closed, the protruding part enters into the protective cover 3 from an opening aperture 8, and a leaf spring 6 is bent to move the shutter 7 into an unblock position. The shutter 7 enters into the protective cover 3 from an opening aperture 9, and the leaf spring 5 is rotated around an engaged part between a center part 5a and a supporting shaft 11 as a fulcrum so as to switch the switch 4 from off to on through an actuator lever 4a.

IPC: G05B19/02
Filed: 1985-06-03
Abstract: PURPOSE:To select and output one arbitrary pulse among pulses at various frequencies by transmitting one signal or a synchronizing signal among plural frequency dividing signals outputted from a frequency dividing circuit to an external load and obtaining the output of a high frequency pulse with a stable period. CONSTITUTION:The frequency dividing circuit 11 frequency-divides several times the output signal of a reference pulse generating circuit 10, and outputs it as a timing signal with the prescribed period.

Title: Digital magnetic recording and reproducing device
Inventor: NISHIDA AKITERU
IPC: G11B5/09
Filed: 1988-05-17
Abstract: PURPOSE:To accurately decide the recording state of data by monitoring the data immediately at the time of recording the data by deciding the validity/ invalidity of the data recorded on each track of a tape based on an output signal from a signal deterioration means which deteriorates a signal reproduced by a monitor head. CONSTITUTION:An equalizer circuit EQ and a change-over switch SW to connect and disconnect the equalizer circuit EQ are provided between a recording and reproducing amplifier circuit 22 and an equalizer circuit 23. Digital data is reproduced by the monitor head 7a in recording, however, at this time, the change-over switch SW is connected to the equalizer circuit EQ side. Therefore, the level of the signal can be set almost equal to the one in ordinary reproduction by changing the frequency characteristic of the signal by the equalizer circuit EQ, and deteriorating the level of the signal reproduced by the monitor head 7a. In such a way, it is possible to suppress an error rate in the recording almost equal to the one in the ordinary reproduction, and to obtain accurate data in the reproduction.

Title: Single-phase induction motor
Inventor: KAWAMOTO TETSUO
IPC: H02K17/08
Filed: 1986-05-23
Abstract: PURPOSE:To reduce a vibration and an adnormal sound at the time of starting a single-phase induction motor by disposing a magnetic piece between the ends of poles in such a manner that the surface of the piece continues with the peripheral surface of the pole opposed to the rotor, thereby reducing a magnetic strain between the rotor and a stator. CONSTITUTION:Since the surface of the magnetic piece 7 of a magnetic wedge 6 continues with the peripheral surfaces of poles 4, 4 opposed to a rotor, air gaps between the inner peripheral surface of a stator and the outer peripheral surface of the rotor become substantially constant, thereby reducing a magnetic strain between the rotor and the stator. Accordingly, a vibration and an abnormal sound at the time of starting can be effectively reduced. Since a mounting piece 8 is bonded by forming it of a metal material or fixedly mounted by press-fitting by forming it of an elastic material, unreasonable force is scarcely applied to a part between the ends 4b and 4b of the pole. Accordingly, since it is not necessary to form a longitudinal groove for a magnetic wedge at the ends 4b, 4b of the pole like the conventional one, the manufacture of the stator 3 is facilitated.

Thereby, the back coating layer is stably formed, so that the obtd. ferromagnetic metal thin film 2 has a lubricant layer 3 containing the lubricant included in the back coating layer which is uniformly transferred onto the ferromagnetic metal thin film 2.

Abstract: PURPOSE:To obtain a molded body of dry ice having a shape providing an optional sectional shape by warming a cylindrical die comprising a good heat conductor and having a penetrating die hole, by a heating means, and allowing the die to contact with a dry ice block. CONSTITUTION:A dry ice block 12 is mounted on a die hole part 3 of die 4 heated 5 at a specified temp.(100-200 deg.C). After holding the block 12 for about 1-5min, the block 12 is lifted, and a molded body 14 of dry ice having a tip shaped to a stick of a small diameter as illustrated by the drawing is obtd. Since, in this stage, a heat buffering space 7 of a large diameter is formed at a bottom surface side of the die 4, thermal influence from the internal peripheral surface of the die 4 to the peripheral surface of the stick 13 formed by the downward extrusion through a nozzle 8 of the die 4 is reduced. Accordingly, there is no fear for causing loss of the stick 3 part by sublimation. The molded body 14 is suitable for use in low temp. remedy of an affected part.

Filed: 1991-05-24
Abstract: PURPOSE:To execute high-speed and suitable control to illuminance over a wide range by correlating plural diaphragm control to gain means in a simple control system. CONSTITUTION:An image is received from an optical system 11 having a diaphragm 12, amplified by an intentifier 13 and guided through a fiber plate 15 to a solid-state image pickup device.
