Title: Control system for operating spin welder
Inventor: TAKADO YUTAKA
IPC: B29C65/06
Filed: 1985-08-16
Abstract: PURPOSE:To stop the servo motor at a specified position, by setting a detector of the rotating position in the servo motor, by feeding back the output to introduce it into a counter of the directive pulse and by controlling the stop of the rotation of the motor by this feed-back pulse after the directive pulse stops. CONSTITUTION:While the servo motor 4 is in motion, a pulse, to be proportional to the rotational angle between an encoder 11 and the motor 4a, is dispatched and the pulse is introduced into a deviation counter 8 through a pulse shaping and synchronizing circuit 7 as a feed back pulse of the position. After a necessary time has passed, the directive pulse 6 is stopped and only the feedback pulse is then input. As the deviation counter 8 reduces the value of deviation, the analog voltage decreases and the rotational speed of the motor 4 correspondingly decreases. The motor 4 rotates until the value of deviation becomes zero and the determination of the position can be completed. If the stop position of the rotation is fit to the phase of the sine wave of the directive pulse 6 in advance to be 0 deg. for example, the motor 4 can be stopped at the state that the directive pulse 6 is not dispatched, and the perfect controlling of the stop position of the rotation is thereby possible.

Filed: 1982-10-16
Abstract: PURPOSE:To accurately perform the quantitative measurement of grease, by a method wherein a fixed quantity chamber is highly pressurized by a plunger prior to sending grease to a grease emitting nozzle under pressure to collapse air bubbles or air in grease to check the grease. CONSTITUTION:When a valve V1 is opened to supply grease into a fixed quantity chamber 11 under pressure and a limit switch LS1 is brought to ON-operation by the movements of a plunger 15 and a piston lever 16 to their retracted ends, the valve V1 is closed. Subsequently, the fixed quantity chamber 11 is highly pressurized by the plunger 15 and, if the plunger 15 is not advanced into the fixed quantity chamber 11, a valve V2 is opened because of no air bubbles in grease and the grease (g) in the fixed quantity chamber 11 is injected in and applied to a bearing B. On the other hand, when air bubbles are mixed in the grease, air bubbles are collapsed and the plunger is advanced little because of volume reduction. In this case, a manual opening and closing valve V3 is opened to introduce the grease into the fixed quantity chamber 11 and the grease having air bubbles mixed therein in the fixed quantity chamber 11 is discharged to drain D.

Title: Microphone
Inventor: WADA HIROTO
IPC: H04R3/00
Filed: 1981-11-12
Abstract: PURPOSE:To suppress the backward sensitivity nearly zero, by arranging two sets of single directivity microphone units back and forth mutually and synthesizing the output of the back microphone with the output of the front microphone via an attenuation circuit. CONSTITUTION:Since microphone units 1, 2 are arranged inversely, the units 1, 2 output aural signals of almost the same amplitude but opposite phase and they are inputted to a synthesis circuit 3. In this case, the output of the unit 2 arranged backward is applied to the circuit 3 via an attenuator 4. As a result, the response of the unit 1 arranged forward toward 180 deg. and that of the unit 2 arranged backward toward 0 deg. are adjusted equally with the attenuator 4, allowing to obtain a cancelled synthesis signal from the circuit 3.

Title: Metal mold for foam resin extrusion forming
Inventor: KITAGAWA RIYUUICHI
IPC: B29C48/06
Filed: 1982-10-15
Abstract: PURPOSE:To obtain an extrusion formed product having a skin layer from a kind of foam resin by a metal mold for foam resin extrusion forming by such an arrangement wherein an opening which is gradually expanded in funnel shape toward its outlet is formed in an internal resin passage piercing through the center of a mandrel arranged in a resin flow passage. CONSTITUTION:When foam resin flowed into a passage 5 moves into a funnel-shaped opening 6, it becomes decompressed condition and it begins foaming and flows out. On the one hand, when foam resin flowed into an outer passage 16 passes through an outer passage slit 4, it becomes such a condition wherein it is hard to foam, since it is applied with the pressure of foaming of resin flowing out of the funnel-shaped opening 6 and its interior becomes a foam core 17, and a foam extrusion formed product A of which surface layer becomes a skin layer 18 of low foaming rate is obtained. To give glossiness to the outer surface of this product, a covering resin is extruded into a resin passage 2 through an extrusion machine 13 for covering resin and a covering resin extrusion slit 10 simultaneously with the foam molding of the product. By this method, a foam extrusion formed product having a foam core and a skin layer each of which differs in foamed condition from the other can be obtained by using one kind of foam resin and the construction of a metal mold can also be simplified.
