Title: Milk amount measuring apparatus for milking apparatus and measuring of total milk amount between milking periods
Inventor: FUIRITSUPUSU POPE KIISUTORA
IPC: G01F15/08
Filed: 1981-05-27
Abstract: A volumetric apparatus for milk (FIG. 1) for use by milking plants in the direct measurement of the quantity of milk collected from a cow in milking. The instrument comprises a vacuum separating chamber 1 for separation of the milk from the milk-air mixture drawn from the cow and, following said separating chamber, a measuring chamber 7 for the milk which at its lower end is provided with a milk outlet opening 15 and a valve plug 16 for selectively closing of said outlet opening. The measuring chamber is outfitted with a measuring means, and the separating chamber 1 is connected to the measuring chamber (7) through a constantly open inlet opening (6) of such size that the same pressure prevails in both chambers throughout the measuring operation. A collecting means follows the measuring chamber and communicates with the measuring chamber for receiving milk therefrom when the outlet opening 15 is opened by the valve plug. An air-conducting pipe (8) extends from adjacent the separating chamber to the collecting means. The measuring means is adapted to make partial quantity measurements while the inflow of milk into the measuring chamber (7) continues.

Abstract: PURPOSE:To obtain a semiconductor device having a gate electrode showing a good Schottky characteristic even after processing and forming the gate electrode by alternately performing polymer formation for protecting a sidewill and etching when processing a Schottky electrode by anisotropic etching, an RIE(Reactive Ion Etching). CONSTITUTION:After implanting ions from above a mask 12a provided on a GaAs substrate 11, heat treatment is performed to form an n-type operation layer 13 by activation and to pile up a WNx film 14a to become a gate elec trode all over a wafer by reactive sputtering while further selectively forming a photoresist 12b. Later, the WNx film 14a is processed by RIE with the photoresist used as a mask to form a gate electrode 14b, when polymer is formed by using CF4 and H2 gas and 50W low power etching by using CF4 and O2 gas are alternately performed once a batch. Thereby, a Schottky elec trode is processed by sputtering under a low bias condition so as to obtain a semiconductor device with the gate electrode having a good Schottky charac teristic for not giving damage to the substrate and the electrode.

Title: Method for removing black product in laser processing
Inventor: KAMEYAMA YASUHARU
IPC: B23K26/38
Filed: 1990-03-28
Abstract: PURPOSE:To completely remove the black product sticking to a processed part by subjecting the neighborhood of this part to a high-frequency discharge in a gaseous mixture composed of oxygen and nitrogen. CONSTITUTION:The black product generated near the processed part when org. matter is processed by using a laser is removed. The neighborhood of the processed part is, thereupon, subjected to the high-frequency discharge in the gaseous mixture composed of the oxygen and the nitrogen.

Title: Production of disk magnetic head
Inventor: TASHIRO KO
IPC: G11B5/187
Filed: 1985-04-15
Abstract: PURPOSE:To produce a disk magnetic head easily and quickly with high accuracy by securing the working allowance of a prescribed size only at a part serving as a counter surface to a medium and forming this part with a step. CONSTITUTION:The working allowance C is secured for a slider original form parts 21 and 22 only at a medium counter surface area respectively. While other areas of both parts 21 and 22 have the same size and form as the final product. Thus the form and the size approximately equal to those of a finished product are obtained just by deleting the area of the allowance C. This shortens greatly the cutting time and this cutting can be performed based on the stepped parts 24 and 25 since the area of the allowance C is stepped. Thus the working is simplified. Furthermore a core original form parts 23 is produced with the area of the allowance C secured previously and cut according to both parts 24 and 25. As a result, the depth of an R/W gap 15 of the parts 23 can be decided with high accuracy.

IPC: H02J7/16
Filed: 1991-04-12
Abstract: PURPOSE:To provide an output controller for a vehicle generator for controlling the generator output appropriately according to the traveling state of the vehicle. CONSTITUTION:In the case of acceleration (S130), deceleration (S170) or constant speed traveling (S190), the control goes to S140 where a correction value data d(+ or -), corresponding to the difference between a battery voltage VBT and voltage values(VL, VH, VM) set at a target output voltage Vreg, is added to duty ratio Duty and finishes the process of (Duty   Duty +d). Upon transition from acceleration to constant speed traveling, the control goes to S200 where a micro value alpha is added to the Duty (alpha>0, Duty   Duty +alpha), and a decision is made whether the VBT is equal to VM at S210. If the VBT is smaller than the VM, the process is ended (generator output increases gradually because the micro value alpha is continuously added in the following process.)

Abstract: PROBLEM TO BE SOLVED: To eliminate a fault introduced to externally discharge cleaning balls from a heat exchanger of a power plant by manufacturing by it using rubber manufacturing composition obtained by substantially uniformly and homogeneously mixing natural rubber with biodegradable substance having faster biodegradable speed than the rubber. SOLUTION: The sponge ball is manufactured by using rubber manufacturing composition containing 100 pts.wt. of natural rubber or mixture of the natural rubber and synthetic rubber and 2 to 70 pts.wt. of biodegradable plastic having faster biodegradable speed than that of the natural rubber as main components. In the manufactured ball, the substance is uniformly and homogeneously contained together with the rubber components, and hence the plastic is rapidly decomposed. Further, the rubber components are exposed with the outer atmosphere for receiving decomposing action due to microorganism on a surface of wide area similar to that manufactured in a thin film state. Accordingly, the decomposition is accelerated as compared with cleaning sponge not mixed with conventional biodegradable substance.

Abstract: PURPOSE:To prevent commodities from being stolen by using a signal from a frequency sensor provided within a radiation area of a transmission wave. CONSTITUTION:An electromagnetic wave having a prescribed frequency is radiated constantly from a transmission antenna 2 into an area. When a frequency sensor 3 set in this area receives a transmission wave, radiates, as an output, an electromagnetic wave having a frequency higher by an integer multiple than the frequency of the transmission wave. The wave radiated from said sensor 3 is received by an antenna 4, and a reception signal is supplied to a receiver 5. When an alarm generator 6 is operated in the presence of the reception signal, the presence of the sensor 3 can be recognized from the presence of an alarm. Accordingly, commodities can be prevented from being stolen by sticking the sensor 3 to the commodities beforehand.

Title: Narrow groove welding method
Inventor: NOMURA HIROICHI
IPC: B23K9/16
Filed: 1979-06-29
Abstract: PURPOSE: To make the height of welding beads constant irrespective of any change in the width of a welding groove by comparing the electric signals of arcs and a reference signal and controlling the speed of welding by the differential signal thereof.  
     CONSTITUTION: When a groove width (l) becomes wide or when the bottom face 12 of the root pass of arc is low, a molten metal pool 4 assumes a low level of molten metal because a welding wire 5 is melted therein at a fixed amount of melting, and this results in decreased electric current and increased voltage. When the groove width (l) becomes narrow or the bottom face 12 of the root pass of arc becomes high, the welding pool level becomes high, resulting in increased electric current and decreased voltage. These electric signals of the arcs are detected with a welding arc current (or voltage) detector 13 and are compared with the reference signal from a reference signal generator 16 by a differential amplifier 15, and the acceleration-deceleration controlling circuit 27 of the travelling motor 17 of a welding carriage 11 is controlled by the differential signal thereof, whereby the quality of the weld zone is improved.
