Title: Cross flow filtration
Inventor: AMAIKE HIDEO
IPC: B01D37/00
Filed: 1993-08-24
Abstract: PURPOSE:To maintain a state suited to filtration for a long time so that a tolerable filtration time is prolonged and enhance filtration efficiency by sealing one side of a filter with a liquid in the early stage of a filtration step and supplying a liquid to be treated to circulate it along the other side of the filter. CONSTITUTION:Water is stored in a storage tank 11 prior to the start of a filtration step, then a drain port 16a is closed and at the same time, water is supplied to a filter device 13 from the storage tank 11 so that it circulates through the filter. If the circulation path is filled with water, an outflow pipe 16b is closed and at the same time, the drive of a circulation pump 12 is stopped and the drain port 16a of a connection pipe 15a is opened. Then the water in the entire circulation path excepting the outer peripheral part of a filter in the filter device 13 and a drain pipe 16b, is drained from the drain port 16a, resulting in a watertight state. Under this state, the circulation pump 12 is driven to start the filtration step. Consequently, the pores for deposited cake and the filter are increased in number as a differential pressure between both sides of the filter is comparatively lower.

Title: Storage circuit
Inventor: MURAKAMI KOUICHI
IPC: G11C16/06
Filed: 1982-11-30
Abstract: PURPOSE:To attain the cost down of a storage circuit using a nonvolatile memory and the miniaturization of packaging by forming two kinds (high and low) voltages from a power supply voltage and applying any of the voltages to a control gate depending on the logical state of data input terminals. CONSTITUTION:When ''H'' is applied to a terminal IN, an output of an AND gate 1 goes to a VDD as shown in Fig. A to turn on a TR9. Further, an ''H'' output of the gate 1 is inverted to turn off a TR4, resistors 5, 6 do not function as a voltage dividing circuit, an output level of a voltage switching circuit 2 goes to a power supply VDD, a write current is applied to a memory cell 8 and its threshold voltage is increased from a VTHS to a VTHA. In the readout of a memory cell after the end of write, since no ''H'' is applied to an enable terminal EN other than at write, the TR4 is turned on, and the output level of the circuit 2 becomes VDD, decreased from the power supply VDD. Since the setting is made in advance as VTHS<VDD'<VTHA, the cell 8 under no write state is turned on, its output goes to 0V and the output of the cell 8 finished for write goes to the VDD as shown in Fig. C.

CONSTITUTION:When the rotation of a main spindle is started, a holder barrel part 22 is rotated, and a vibration shaft 34 is also rotated integrally with the holder barrel part 22. At this time, the vibration shaft 44 is axially moved in an arrow mark B direction by a compression coil spring 52, but a compressed air is fed into a groove space 58 from passages 32, 34, 36, when the communicating hole 42 of the holder barrel part 22 is communicated with the passage 36, and the vibration shaft 44 is axially moved in an arrow mark A direction. Moreover, when the rotation is continued, the communicating hole 42 is communicated with discharge passages 37, 38, and the vibration shaft 44 is moved in the arrow mark B direction by the energizing force of the compression coil spring 52 once again. The vibration shaft 33 is repeated at its reciprocating axial movement with the holder barrel part 22 and vibration shaft 44 being rotated, and a polishing tool 64 is rotated while being vibrated in the axial direction, so, the movement optimum for a polishing work can be obtained.

Title: Radar equipment
Inventor: TANAKA YASUTOSHI
IPC: G01S13/42
Filed: 1982-11-30
Abstract: PURPOSE:To compensate for phase vibration in a transmission pulse by causing a phase vibration in a pulse opposite in the characteristic to a transmission type signal. CONSTITUTION:The characteristic of a phase variation in a transmission pulse depending on characteristics of a power amplifier as shown in the drawing (a) is measured and displayed on an oscilloscope, an X-Y recorder or the like. Based on such a data, a phase vibration value is sampled manually for a unit time allowing a phase shifter for compensation to respond to rewriting corresponding to a set phase shift level to determine a phase difference between this and the latter half of a pulse free from phase variations. The phase difference is a necessary correction value corresponding to sampling times. This correction value is quantized by the quantization unit of the compensation phase shifter, inverted in the symbol and applied to the phase shifter corresponding to the sampling times. With such an arrangement, as shown in the drawing (b), a transmission type signal has a phase variation opposite in the characteristic to the phase variation characteristic of the drawing (a) and thus, the relative phase of a transmission pulse emitted from an array antenna with respect to a coherent signal gives a phase waveform with limited variation as shown in the drawing (c).

Title: Manufacture of flow rate control valve
Inventor: YOKOMIZO TOMOKI
IPC: G01M13/00
Filed: 1987-08-26
Abstract: PURPOSE:To obtain a high-accuracy, inexpensive method by carrying out fine adjustment machining by using the specific relation between upstream and downstream pressure of a valve in test facilities and its absolute temperature. CONSTITUTION:The characteristics of the control valve to be manufactured are so set that a capacity coefficient (Cv value) indicating the easiness of a gas in a noncritical state to flow is prescribed under the necessary pressure and flow rate condition of the scheduled facilities. This valve is manufactured by adjusting finely and machining the needle 10 of a valve which is machined roughly in advance by using different conditions by test facilities. At this time, the gap part between the needle 10 and a port 11 serves as a throttle mechanism provided with a fluid flow passage for adjusting a flow rate by varying the extent of contraction of area. Then the fine adjustment machining is carried out by using the constant relation, i.e. (P1+P2)<2>/{T1/2(P1<2>-P2<2>)<1-/2>= constant, where P1 and P2 are the upstream pressure and downstream pressure and T is the absolute temperature of the fluid.
