Title: Machining method of reduction gear for high reduction ratio
Inventor: KOJIMA MASAAKI
IPC: B23P15/14
Filed: 1994-02-03
Abstract: PURPOSE:To manufacture reduction gears for high reduction ratio which are inexpensive without reducing their quality when a prime mover for high speed such as gas turbine and steam turbine is used. CONSTITUTION:In reduction gears for high reduction ratio which are constituted by meshing small gears A with a large gear B, pitch error and surface roughness of the small gears A are finished by a predetermined machining method and the large gear B is finished by rough finish machining to cover the large gear B by copper plating. Projections 2 of copper plating which float from tooth faces of the large gear B are removed due to relative slide and rolling between tooth faces by meshing and rotating the large gear B with the small gears A to finish surface roughness of the tooth face to a specified roughness. The thickness (b) of copper plating which covers the large gear B is set to the thickness which slightly exceeds average roughness (a) calculated by measuring roughness of the tooth face of the large gear B.

Title: Manufacture of positive plate for pasted lead battery
Inventor: TOKUNAGA AKIO
IPC: H01M4/20
Filed: 1985-01-24
Abstract: PURPOSE:To improve the initial discharge performance of an immediately used battery and increase its life by using a charged positive plate produced by forming a plate made by packing a paste containing a highly anisotropic graphite in a low-concentration sulfuric acid solution by a specific current level. CONSTITUTION:After a plate made by packing a lead battery paste containing a highly anisotropic graphite is aged, the aged plate is formed in dilute sulfuric acid with a specific gravity of 1.01-1.05 by a current 100-150% of the theoretical capacity of the positive active material. Then the formed plate is washed with water and dried. For example, after 1.0wt% of a highly anisotropic graphite with particle size of 150-1,200mu is added to a lead powder composed of metallic lead and 75% of lead oxide and the thus prepared mixture is kneaded with dilute sulfuric acid to prepare a positive paste with a density of about 4.5g/cm<3>, the thus prepared positive paste is packed into a lead alloy grid and the thus formed plate is aged. Next, the aged plate is formed in dilute sulfuric acid with a specific gravity of 1.01-1.05 by a current 100-150% of the theoretical capacity. After that, the formed plate is washed by flowing water and then dried. A pasted lead battery is produced by combining the dried plate with an immediately used negative plate with adequately great capacity.

Title: Dc-ac inverter circuit
Inventor: OOSHIRO MASAHIRO
IPC: H02M7/537
Filed: 1978-02-07
Abstract: PURPOSE: To prevent the simultaneous turning ON by inverting the polarities between the positive feedback current in one collector current of push-pull connected transistor thereby applying the reverse bias on the other base of the transistor.  
     CONSTITUTION: The output from the current transformer T3 placed between the transformer T2 and the collectors of pushpull transistors Q1, Q2 is positie feedback to the base of Q1, Q2, while diodes D1, D2 are inserted in the direction to block Q1, Q2 through the base drive circuit 1. Consequently the positive feedback current provided by the collector current of one transistor as well as the feedback current from the transformer T3 when a reverse base current flows due to the polarity inversion of the base drive source during the storage time of one transistor can apply reverse bias on the other base of the transistor, thereby simultaneous turning ON can be prevented without requiring the interval.

Abstract: PURPOSE:To provide an apparatus for diagnosing deterioration of paint film which can perform adequate judgment all the time, can perform operation simply and positively and can perform highly accurate deterioration diagnosis by eliminating the room for subjectivity when the deterioration diagnosis of a paint film is performed. CONSTITUTION:A probe 10 is applied on the surface of a paint film 9 whose deterioration is to be performed. Impedance Z1 of the paint film is detected with a current which flows through the paint film 9 when a voltage is applied across the probe 10 and ground metal 11. The logarithm log Z of the paint film impedance Z has the linear relation with a time (t). Therefore, analysis is performed with a personal computer 1, and the degree of deterioration of the paint film 9 is judged. At this time, the average value of the impedances Z1 is multiplied by a temperature correcting coefficient (k), and the value is converted into the value below reference temperature of 25 deg.C. Then, the degree of deterioration is judged.

Abstract: PURPOSE:To reduce the number of parts and to prevent troubles from happening by changing the operation time of a solenoid, working a changeover member on a different cam surface without working the changeover member by a driving force of the solenoid and preventing the changeover member from abutting against other members. CONSTITUTION:When a plunger 136 is sucked by operating the solenoid S, a 1st protrusion 131a is drawn so that a turning lever 131 is turned, and also a driven member 132 is turned. When the sucking time is short, a pin 133 of the member 132 is not engaged with a cam surface 70a of a cam gear 70, and the member 132 keeping under the state of positioning in a notched part 70f is restored by a spring 139. After restoring, since the pin 133 passes along the exterior of the cam surface 70a, the member 132 does not turn. During the sucking process of the solenoid S, since the member 132 is turning toward the center of the gear 70, and when the sucking time is long, the rotating cam surface 70a is engaged with the pin 133. As a result, the member 132 is turned by following the cam surface 70a, and a pin 134 drives a head chassis 30 and a fast forward changeover driving plate 130. The head chassis 30 is returned in the direction of X, and also a changeover plate 80 is turned.

IPC: H01M2/02
Filed: 1983-01-28
Abstract: PURPOSE:To optimize the heat insulating characteristics and strength of a heat insulating layer and improve the battery characteristics by dispersing a heat insulating material mainly made of inorganic fibers in a liquid and filtering the dispersion liquid to form the heat insulating layer so that the density is adjusted according to filtering conditions. CONSTITUTION:Inorganic fibers are used as a heat insulating material and they are dispersed in a dispersion medium, e.g., in water, and a predetermined quantity of a dispersion liquid adjusted to the predetermined density is injected to be filtered between a battery outer case 1 provided on a filtering jig 2 and an electrode dummy section 3. A glass filter, a metal net, filtering cloth, etc. are used as the filtering filter section 4, and they are suitably selected according to filtering conditions, thus the formed density of a heat insulating layer is adjusted according to the ratio of the heat insulating material component in the dispersion liquid and filtering conditions during the filtering process. That is, the density of the heat insulating layer can be adjusted by making the pressure in a decompression chamber 6 variable. Accordingly, after a cylindrical heat insulating layer 10 with a bottom is formed from the inner wall of the battery outer case 1 toward one opening section side, it is removed from the filtering jig and is dried, then a bottom cover 11 is welded.

Title: Band-pass filter device
Inventor: SAEKI AKIO
IPC: H03H7/01
Filed: 1984-01-27
Abstract: PURPOSE:To improve the overall characteristics and to attain miniaturization of a BPF (band-pass filter) device by cascading a multi-stage filter and a 2-stage filter and therefore reducing the filter Q value. CONSTITUTION:For the pass characteristics of a multi-stage filter 3, the out-band characteristics are sharp and the in-band characteristics are not flat. Then the attenuation is given to upper and lower limit frequencies of band width. While a 2-stage filter 4 shows a low level of attenuation at two points near upper and lower limit frequencies of band width and has a peak level of attenuation at a point near the passing center frequency with the gentle out-band attenuation characteristics. Both fillers 3 and 4 are cascaded to each other via a matching circulator 5 to compensate the characteristics of both filters with each other. Thus the flat pass characteristics are obtained within a band, and the attenuation characteristics having sharp rises at upper and lower limit frequencies of band width can be obtained.
