Abstract: PURPOSE:To economically obtain high-quality 2-chlorocarboxylic acid useful as a raw material for medicine or agricultural chemical using a relatively safe catalyst in good yield, by carrying out chlorination of carboxylic acid raw material using the same kind of acid anhydride as a raw material carboxylic acid as the catalyst. CONSTITUTION:An aliphatic carboxylic acid raw material such as propionic acid, lactic acid or valeric acid is subjected to chlorination with Cl2 gas, etc., at 90-150 deg.C, preferably 110-140 deg.C using an anhydride of same kind of carboxylic acid as the raw material until conversion of the carboxylic acid attains >=99.5% to provide the high-quality aimed compound expressed by the formula (R is 1-4C n-alkyl) such as 2-chloropropionic acid 2-chloro-n-lactic acid, 2-chloro-n-lactic acid, 2-chloro-n-valeric acid or 2-chloro-n-caproic acid. The acid anhydride is used at an addition amount of 8-20 part acid anhydride based on 100 part carboxylic acid raw material. The aimed compound can be supplied to an industrial raw material without carrying out purification such as distillation, because the compound is obtained as very clear reaction liquid.

IPC: F24H1/10
Filed: 1996-04-20
Abstract: PROBLEM TO BE SOLVED: To stabilize quickly a hot-water discharging temperature immediately after changing the travel of a bypass valve. SOLUTION: When a set temperature is changed (S4: YES) during hot-water discharging operation through feedforward control and feedback control (S3), and the opening and closing operation of a bypass solenoid valve is effected (S5: YES), the hot-water discharging control is effected by only feedforward control (S9) for four second when an inlet water flow rate is more than 4L/min (S7) or for two second when it is less than 4L/min (S7). When temporary and sudden overshoot or undershoot is generated due to the opening and closing operation of the bypass solenoid valve, the hot-water discharging control is effected without receiving any affection of them whereby a hot-water discharging temperature is stabilized quickly.

Abstract: PURPOSE:To obtain a circuit which oscillates easily with low power consumption by connecting P and N-channel MOSFETs and C-MOSFET together in series between power terminals, by connecting a resistance in parallel to C-MOS and by providing a gate with a control input terminal. CONSTITUTION:Between power supplies VDD and VSS, P-MOSFETs T11 and T13  and N-MOSFETs T12 and T14 are connected and resistances RDD and RSS are also  connected to T13 and T14 in parallel.

Title: Structure of reinforced ground and method for reinforcing ground
Inventor: HORIIE MOICHI
IPC: E02D3/00
Filed: 1994-05-13
Abstract: PURPOSE:To enhance construction properties by installing a vertically oriented cylindrical body made of geotextile in an excavation above or in the ground, packing and consolidating earth and sand in the cylindrical body, and covering the cylindrical body with earth and sand. CONSTITUTION:The dead weight of fill 16 is transferred to the ground below through reinforcement 14 and a wedge-shaped sliding surface appears beneath the installed plane of the reinforcement 14. The level of the sliding surface is lower than it is when fill is constructed on original ground 12 that has no reinforcement therein. Therefore, the weight of a clod located above the sliding surface beneath the reinforcement 14, and the resistance of the clod to movement along the sliding surface, are increased, thereby reinforcing the ground 12. When the dead load acts on the reinforced ground 10, the reinforcement 14 is deformed in a diameter-increasing direction and resists the dead load. Further, the reinforcement 14 does not sink because of its light weight as compared with concrete blocks, and is kept in a predetermined position since it follows the deformation of the ground 12. Thus the bearing force and the stability of the ground can surely be enhanced and construction is facilitated.

Title: Rope slack prevention device and paying-out prevention device with rope slack prevention device
Inventor: FUNATO KOJI
IPC: B66D1/50
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent unnecessary paying-out of a rope after landing of a suspended cargo on a floor. SOLUTION: A load F is applied to a hoisting rope 1a through a link 32 and a roller 33 by extension and contraction of a hydraulic cylinder 34. At that time, the angle θ of the link 32 varies according to a slack amount of the rope 1a. By controlling a decompression degree of a solenoid proportional valve 27 according to the angle variation of the link 32, the load F acting on the rope 1a is kept a constant value (=F0). When the angle θ of the link 32 exceeds a prescribed value (θ0+α), it is judged that a suspended cargo 6 lands on a floor, and a solenoid valve 24 is changed over to stop driving for a drum 1. After the stop of the drum 1, the load also acts on the winding-up rope 1a regardless of the angle θof the link 32 to prevent unnecessary paying- out of the rope 1a.

Abstract: PURPOSE: To always perform the fail safe operation by separating the system when a short-circuit failure is detected, and separating the system when the speed value exceeding the preset value which is higher than the maximum value is indicated.  
     CONSTITUTION: An output fP of an ATC speed pattern generating circuit 8 is compared with an output fPCR of a pattern-scanning pattern generating circuit 101 in an abnormal ATC speed pattern comparator 102. If fP<fPCR, the output fP is judged to be normal, and an AC signal f 6  is sent out from the comparator 102. In the case said output f 6  is present, any failure is not detected in a failure detecting circuit 14, and an AC signal f 4  is sent out from the circuit 14; an AC signal f 7  is sent out from an AC AND circuit 103. The output actuates a failure detecting relay CHR via an AC amplifier 104. Said relay is released, when the fialure is detected in the cicruit 14, or when abnormality is detected i an ATC speed pattern. Therefore, the fail safe operation can be always performed.
