Title: Fine powder manufacturing method and its device
Inventor: WATANABE TOSHIO
IPC: B01J2/02
Filed: 1987-03-09
Abstract: PURPOSE:To manufacture fine particles with a narrow range of grain size distribution by allowing a high-speed air flow to move downward around a continuous columnar falling flow of a molten material and the air flow to hit an impact body which moves with a high speed in the contracted part located at the end part of the falling flow. CONSTITUTION:A nozzle 5 which permits a molten raw material to flow down from a melting device is provided in a funnel-shaped throttled part 11. A rotary disk 1 having a plurality of blades 2 mounted on its periphery is housed in a casing 13 and rotates at high speed. As the blades 2 are formed at an inclined angle with a shaft, the axial flow of an atmospheric air is generated and proceeds from the top to the bottom under the rotational impact of the disk 1. This axial flow passes through the throttled part 11, enveloping the tip of the nozzle 5, then guides the flow of the molten material to the blades 2 stably. Thus the falling flow of the molten material is given a uniform impact. The molten material which hits the blades 2 is sprayed in the form of fine particles and discharged.

Title: Hardware and method for connecting shielding plate
Inventor: KAMEI YOSHINOBU
IPC: E04F13/08
Filed: 1995-02-18
Abstract: PURPOSE: To provide hardware and a method for connecting shielding plates wherein errors in the dimensions of shielding plates or connecting hardware are simply adjustable, and wherein as a result connection of desired performance is simply accomplished with reliability without any skillful engineer. CONSTITUTION: The title connecting hardware is formed by bending sheet metal so that its cross section has a Z shape, and thus includes a lower side section 13e, an upper side section 13a, and a middle side section 13c. Base hardware is installed on a supporting body, such as a wall, encircling a space to be shielded. The lower side section 13e of the connecting hardware 13 is placed on the base hardware, and one end of a shielding plate is inserted into between the lower side section 13e and the middle side section 13c. One end of another shielding plate is inserted into between the upper side section 13a and the middle side section 13c. Screws are driven through the connecting hardware and the shielding plates to the base hardware to join them with one another.  In this method the connecting hardware functions as a ruler and thus a required lap length of shielding plates is simply obtained with reliability.

Title: Extruder
Inventor: OOTSUGI SHIYOUZOU
IPC: B29C48/30
Filed: 1980-04-24
Abstract: PURPOSE:To prevent the stagnation of a resin at the head of a screw by disposing a screw shaft and a breaker plate with their center axes being displaced to each other. CONSTITUTION:A breaker plate 4 is disposed with its center axis X being shifted from the center axis O of a screw shaft by a distance alpha. The molten resin introduced through a narrowed passage 2 formed with a reducing piece 3 flows through a breaker plate 4 and a passage 6 formed in an adapter 5 into a passage formed within a die holder 7. Since the breaker plate 4 is disposed with its center axis displaced from the center axis of the screw shaft by a distance alpha, a part of the molten resin flows over the head 1 of the screw, therefore, the molten resin will not stangate at the head of the screw. Since the stagnation of the molten resin is thus prevented, the thermal denaturation of the resin is prevented, so that the molded product is free from rough surface.

Besides the zinc 21 overflows a lower weir 9, and is discharged from a discharge port 17 for zinc 21 and recovered from an outlet 20.

Title: Capacitor type resistance welding machine
Inventor: OMATSU HIDEFUMI
IPC: B23K11/26
Filed: 1985-03-18
Abstract: PURPOSE:To increase the accuracy and speed in charging by providing the first comparator to compare the reference voltage with capacitor charging voltage and by arranging the second comparator to compare the output of integrating circuit with the rectifying value of the power source voltage as well. CONSTITUTION:A power source voltage is inputted into OP amplifier 27 being subjected to full-wave rectification with rectifier 26. In this case, a clock pulse signal b is outputted, in succession a capacitor 29 is gradually discharged and the rush current at the charging initial period is prevented. The maximum phase of the ignition pulse signal m at the capascitor charging time is decided by comparing the reference voltage i of variable resistor 42 and saw tooth wave e by OP amplifier 36. The reference voltage i for charging voltage setting is compared by the differential amplifying type comparator consisting of resistors 43-46 and OP amplifier 47. The current reduction at the charging finishing period is thus prevented and high speed charging can be performed as well as the improvement in charging accuracy.

Title: Motor with reduction gear mechanism
Inventor: UCHIYAMA HIROSHI
IPC: H02K7/116
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To provide noiseless operation for long service life even if a load change is received, by disposing a thick-wall load receiving part formed by increasing wall thickness to the larger load side applied to an output shaft from a load. SOLUTION: At a shaft holder 3e, a thick-wall load receiving part 21 is formed, and the thick-wall load receiving part 21 is disposed on the longer axis side of an ellipse of a thicker-shaft holder 3e. In the thick-wall load receiving part 21, when maximum load is applied to a motor arm connected outside a gear case 3 of an output shaft 20, large bending stress along the axial direction of an armature shaft 7 is applied to the output shaft 20. By preventing an increase in a clearance between the output shaft 20 to the stress direction and a fifth bearing 34 so as to be against bending stress, no looseness is caused between the fifth bearing 34 and the output shaft 20. It is thus possible to attain noiseless operation even if a load change is received, for which no impact noise occurs.

Title: Gel type lead-acid battery
Inventor: KAWANAMI YOSHIHARU
IPC: H01M4/57
Filed: 1983-03-29
Abstract: PURPOSE:To make possible to penetrate silicic anhydride fine powder into pores of granules by using granules obtained by granulating dilute sulfuric acid and lead powder as positive active material in a clad type lead-acid battery using gel electrolyte. CONSTITUTION:100ml of dilute sulfuric acid with sp.gr. 1.20 is added to 1kg of lead powder having an oxidation degree of 70% and they are granuled with a granulating machine to form granules. The granules are filled in a tube to form a clad type plate. Gel type electrolyte comprising dilute sulfuric acid with sp.gr. 1.28 containing 10wt% silicic anhydride is used to form a clad type lead- acid battery. Because silicic anhydride fine powder penetrates relatively large pores between granules and its concentration is uniform, pushing out of dilute sulfuric acid by gas evolved during charging is decreased and diffusion of electrolyte is increased to improve battery performance.
