Title: Electromagnetic engaging device with synchronizer
Inventor: KAWAMOTO MUTSUMI
IPC: F16D27/10
Filed: 1987-09-26
Abstract: PURPOSE:To prevent generation of abnormal sound and to improve durability by disposing a synchronizer between engagement elements not to obstruct a magnetic path formed by excitation in a tooth electromagnetic clutch. CONSTITUTION:When an electric current is applied on a coil 24, strong magnetic force is generated in a coil 24, and a rotor 21 is magnetized to form a magnetic path 33, so that a driven-side armature 26 is attracted to the rotor 21 against the spring force of a spring 30. At this time, according to the degree of intensification of the friction material of a synchronizer 28 contacting the rotor 21 and the armature 26, the torque capacity transmitted from the drive side to the driven side is gradually increased and the rotational frequency of the armature 26 approaches the rotational frequency of the rotor 21. At the time of the rotational frequencies of the armature and the rotor are synchronized, a tooth 22 and a tooth 27 are meshed to connect the drive side rotor 27 and the driven side armature 26. Accordingly, the relative rotation can be decreased without control by frictional force produced by electromagnetic force.

Title: Magnetic disk
Inventor: ISHII TOSHIO
IPC: G11B5/73
Filed: 1992-09-11
Abstract: PURPOSE:To make it possible to form a magnetic film at a high temp. and to improve missing error characteristics by regulating the span of the minute/ waviness of the surface of a substrate to <=50mum. CONSTITUTION:The span of the fine waviness of the surface of a substrate is regulated to <=50mum. Since this span is sufficiently smaller than the width (2.0mm) and length (2.8mm) of the slider part of a magnetic head, the effect of the minute ruggedness of the surface of the substrate on the floating characteristics of the head is reduced, the floating characteristics of the head are stabilized and electromagnetic transducing characteristics such as missing error characteristics are improved. In the case of a Ti substrate, the surface is mechanochemically polished with abrasive grains of Al2O3. The surface roughness (Ra, Rmax) of the surface of the substrate after polishing depends on the grain size of the substrate as well as on polishing conditions. Since the span of minute waviness also depends on grain size, the grain size of Ti is preferably regulated to <=50mum.

Title: Manufacture of multilayer interconnected semiconductor integrated circuit device
Inventor: TONARI SHINICHI
IPC: H01L21/3205
Filed: 1988-09-27
Abstract: PURPOSE:To prevent difference in thickness of an insulating film at the shoulder part of a lower aluminum wiring layer and at the flat part scarcely by depositing and forming the insulating film mainly consisting of polyimide over the whole surface of a semiconductor substrate including the lower wiring having an inorganic or organic insulating film left on the side surface thereof. CONSTITUTION:A silicon nitride film 3 is etched by about 1mum by reactive ion etching utilizing carbon tetrafluoride gas plasm until the surface of a lower aluminum wiring layer 2 is exposed. Because this etching is anisotropic etching, the silicon nitride film 3' is left on the side surface of the lower aluminum wiring layer 2. Lastly, polyamide precursor solution is applied by spin application process so that the film thickness at the part may be about 1mum, and baking up to about 400 deg.C is carried out stepwise to form a polyimide interlayer insulating film 4. In this case, since polyamide precursor solution is applied to the shoulder part of the lower aluminum wiring layer 2 on the basis of the surface of the silicon nitride film 3', the polyimide interlayer insulating film 4 formed on the shoulder part of the lower aluminum wiring layer 2 scarcely differs from that formed on the flat part.

Title: Copying method
Inventor: IWAMOTO MINORU
IPC: G03G15/01
Filed: 1987-09-29
Abstract: PURPOSE:To make an original entirely black, to form a solid black copy image, and to disable the copy image to be read when a copy is taken again by synthesizing an image to be copied by using toner which has the same color, transparency, and no sensitivity to a photosensitive body after undercolor formation. CONSTITUTION:A specified area part of an obtained copy can be read, but a copy obtained from said copy becomes entirely black and can not be read by stamping a copy inhibition seal impression and specifying a copy inhibited area. In this case, transparent toner is used to take a copy and then when a copy is further taken again, the whole original becomes black because of the characteristics of the photosensitive body and the copy image is entirely black. Consequently, the seal inhibition seal becomes effective.

Title: Self-excited 1-transistor inverter
Inventor: TAKAHASHI KEIJI
IPC: H02M7/537
Filed: 1985-10-31
Abstract: PURPOSE:To eliminate unintentional ON of a transistor by forming a resonator by a tank circuit consisting of the secondary winding of an output transformer and a tank capacitor, and providing an attenuator for attenuating a ringing surge generated in the transformer. CONSTITUTION:When an AC power source is turned ON, a base current flows through a bias resistor 38 to a transistor 32 with increase in the output of a full-wave rectifier 2. When the transistor 32 is turned ON, an inverter 3 is oscillated by the resonance of the inductance of a feedback loop from the collector of the transistor 32 through the primary winding 31P, feedback winding 31F, a resistor 36 and a capacitor 35 to the base and the secondary winding 31S with a capacitor 33. Thus, a high-frequency output is generated in the winding 31S of an output transformer 31. A resistor 36 inserted into the feedback circuit prevents the excess effect of a ringing surge across the base and the emitter of the transistor 32 to prevent it from again becoming ON.

Abstract: PROBLEM TO BE SOLVED: To continuously manufacture a slurry and to facilitate a regulation of a concentration by supplying a liquid from the midway of a screw pump, mixing the liquid with a powder, boosting the mixture, and lowering a pressure at a discharge port of its pump at once. SOLUTION: A screw pump 10 has a casing 12, and a rotor 13, and has a powder supply unit 14 provided at a suction side 11s. The unit 14 has a motor 15 for rotating the rotor 13. The motor 15 and the rotor 13 are coupled to a rotary shaft 16 through an Oldham coupling 17. Coal powder is charged in the unit 14, its powder is sucked in a gap between the rotor 13 and the casing 12 of a screw pump part 11, and sequentially extruded at its discharge side 11d. During this period, the powder is mixed with the liquid supplied from supply tubes 18, 19, and boosted toward the side 11d. When the mixture is discharged from a discharge port 20, its pressure is lowered at once, thereby generating a shearing force. Then, the mixture is thus fluidized to a slurry. Thus, the slurry can be continuously manufactured in a short time and can deal with a change in its concentration.

Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a perforated plate type sound absorbing panel low in cost with a high sound absorbing coefficient in a low frequency sound area of 100-500 Hz. SOLUTION: This sound absorbing panel 1a is formed by forming a large number of sound absorbing holes 3 in a wood panel body 2 in the state of piercing the front and rear faces, and bonding a wood sound absorbing membrane plate 4 with a thickness of 0.2-3.0 mm to the surface of the panel body 2 to close the sound absorbing holes 3.
