Title: Pump operating condition monitor
Inventor: NISHIKAWA SHINJI
IPC: F04D15/00
Filed: 1986-11-29
Abstract: PURPOSE:To obtain sure monitoring of the pump operating condition, by judging the pump operating condition after comparing detected values on the discharge pressure, suction pressure, flow rate, and pump shaft power with the set values for the normal operation. CONSTITUTION:The detected signals from a discharge pressure detector 12, a shaft power detector 13, a suction pressure detector 14, and a suction flow rate detector 15 are input into a judgement device 16.

IPC: H02P27/08
Filed: 1989-11-01
Abstract: PURPOSE:To facilitate adjustment of setting of predicted resonance frequency by sequentially lowering the carrier frequency, by a predetermined amount with predetermined interval, based on a command from a frequency operating circuit receiving a frequency lowering command from a vibration detecting circuit upon occurrence of vibration in the motor current.

Operating point of carrier frequency fc makes transition such that P1 P2 P3... and the carrier frequency fc lowers sequentially such that fc1 fc2...-fc3... with predetermined interval until resonance ceases. If resonance does not cease even if the carrier frequency fc lowers to the lower limit, the frequency operating circuit 1 provides an inverter operation stop command BS thus stopping operation of an inverter. By such arrangement, adjustment concerning to setting of predicted resonance frequency can be facilitated.

CONSTITUTION:Between the first installing member 1 and the second installing member 2 which consists of a magnetic body metal, an elastic body 3 is provided, and an operation chamber 4 an operating liquid is sealed is formed in the elastic body 3. To a movable plate 7 to compose one wall surface of the operation chamber, whose outer periphery is supported elastically by the second installing member 2, a magnet device 10 having a permanent magnet 11 and an electromagnet 12 is installed from the operation chamber 4 side, and an air gap 16 is formed between the outer surface of the movable plate and the bottom wall 2a of the second installing member. When a high frequency oscillation is generated, the coil current of the electromagnet is controlled so as to regulate the suction force between the bottom wall, and the movable plate 7 is displaced to the reverse phase, so as to control the liquid pressure variation of the operating liquid positively. Since the electromagnet is in the operating liquid of the operation chamber, while the permanent magnet is used concurrently to reduce the load of the electromagnet, the heating is suppressed, and the reduction of the vibration absorbing performance can be prevented.

Title: Production of maleamic acid and its ester
Inventor: KUME YASUHITO
IPC: C07C233/09
Filed: 1992-10-23
Abstract: PURPOSE:To produce a maleamic acid ester by producing maleamic acid from maleic anhydride and ammonia and then reacting the resultant maleamic acid with an alcohol. CONSTITUTION:A solution prepared by dissolving maleic anhydride in an inert solvent is placed in a reactor. On the other hand, ammonia gas is introduced into a space part of the reactor and absorbed from the contact surface thereof with the solution therein. The absorbed ammonia is then made to react with the maleic anhydride to produce the objective maleamic acid. An alcohol is further added to the resultant solution containing the maleamic acid to produce the objective maleamic acid ester according to the esterifying reaction. Thereby, the high-purity maleamic acid is obtained in high yield. As a result, the maleamic acid ester is prepared in the high yield and purity by directly adding the alcohol to the reactional solution according to the esterifying reaction without separating and purifying the maleamic acid.

Title: Concentration device
Inventor: TORIGOE HIROSHI
IPC: B01D1/00
Filed: 1986-12-01
Abstract: PURPOSE:To reduce impact-contacting speed, by providing a circulation nozzle to permit the flow line of waste fluid returning to an evaporation drum to curve downward obliquely in a concentration device which returns waste fluid absorbed by the evaporation drum and heated by a heater to the evaporation drum using a circulation nozzle. CONSTITUTION:Waste fluid 2 is absorbed by a circulation pump 4 from a spent fluid outlet 3 located at the lower end of an evaporation drum 1 in which the waste fluid 2 is stored. Then the waste fluid is conducted to a heater 5 and heated there. Then, the heated waste fluid is returned to the evaporation drum via a circulation nozzle 6. At that time, moisture contained in the waste fluid is separated. This circulation nozzle 6 is connected to the evaporation drum 1 in such a manner that it faces downward obliquely. Therefore, the flow line of the waste fluid 2 returned to the evaporation drum 1 curves downward at a gradient angle alpha. For this reason, the variation of a fluid level in the evaporation drum is significantly limited, and the deterioration of water quality at the outlet of the title device is also prevented, because the waste fluid which contacts the opposite wall of the evaporation drum with impact is not scattered into the air.

Title: Manufacture of semiconductor device
Inventor: YAMAGUCHI TSUNEO
IPC: H01L21/308
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent a non-processing region covered with a photoresist from being etched in pattern etching wherein hydrofluoric acid anhydride is used as etching solution. SOLUTION: A process of removing a desired region an oxide film 2 formed on a semiconductor substrate 1 is composed of a step of covering a non- processing region with a photoresist 3 and a step of etching the oxide film 2 to a desired degree with an etching solution. In the step of covering the non- processing region with the photoresist 3, heat treatment is not performed after rinsing and the oxide film 2 in the subsequent step is etched. Since the heat treatment is eliminated prior to etching, fine voides in the photoresist are prevented from being developed, the reactive molecules in the etching solution do not reach the non-processing surface to etch the non-processing region and pattern etching by the etching solution is performed.

Filed: 1986-12-01
Abstract: PURPOSE:To form a non-cyclic code converter by providing plural directionality couplers to couple to a ring-shaped microstrip line and a microstrip line and combining a signal to go around the ring-shaped microstrip line and a signal reflected by the directionality couplers. CONSTITUTION:To a ring-shaped microstrip line 1, two directionality couplers 2 and 3 are coupled with a reflecting coefficient at a connecting point as (r) and a transmission coefficient as (t). The ring-shaped microsstrip line 1 is composed of the square of a length L of one side and a directionality couplers 2 and 3 are respectively coupled to two sides facing the square. Thus, the transfer function (Z conversion) of an output at terminal B and C comes to be formulas I and II. Consequently, under the the conditions of r2=1/2, the denominator of the formulas I and II comes to be '1' and the transfer function comes to be non-cycle. Namely, the signal outputted from a circuit outputs the (pulse) of the special number even when the resistance for an amplitude loss is not provided, and converges. From the formulas I and II to the input of '1' from a terminal A, the output of the direction of (1, 1) is obtained from a terminal B, the output of the direction of (1, -1) is obtained from a terminal C and the code conversion is executed.
