Title: Production of para-hydroxybenzoic acid
Inventor: SUZUKI TOSHINOBU
IPC: C07C65/03
Filed: 1992-09-25
Abstract: PURPOSE:To obtain the subject compound useful as a raw material for high polymer materials, a raw material for medicines and agrichemicals from an intermediate or a by-product of Kolbe-Schmitt reaction in high yield by carrying out transfer reaction of salicylic acid potassium salt in the presence of salicylic acid potassium substituted with a specific substituent group. CONSTITUTION:Dried powdery salicylic acid potassium salt is charged into a pressure-resistant reactor in the presence of a compound expressed by the formula (R is alkyl, alkenyl, alkynyl, alkoxy, amino, imino, acyl, formyl, phenyl, etc.; (n) is integer of 2-4) and as necessary, an inactive reactional medium such as biphenyl is added thereto and the reactional system is pressurized with carbon dioxide and salicylic acid potassium salt is subjected to transfer reaction under 8kg/cm<2>G reactional pressure at 290 deg.C for 1hr while stirring. Thereby, the objective para-hydroxybenzoic acid useful as a raw material for high polymer materials, medicines and agrichemicals is obtained in high yield from salicyclic acid potassium salt which was an intermediate or a by-product of Kolbe-Schmitt reaction.

IPC: F04C29/02
Filed: 1992-09-25
Abstract: PURPOSE:To prevent the condensation of high pressure refrigerant through the rise of inlet pipe surface temperature and low pressure refrigerant temperature by providing a part of a precooling pipe with an expansion chamber for lowering the mass speed of circulating refrigerant, and forming this expansion chamber into a double pipe. CONSTITUTION:A refrigerating cycle is formed into a circulating cycle of the discharge pipe 12 of a compressor 1   a precooling heat exchanger 15   a precooling pipe 14   condenser 16   a capillary tube 17   an evaporator 18   a compressor 1. In such constitution, the precooling pipe 14 is partially expanded, and an inlet pipe 11 is passed therein to form an expansion chamber 20 of double pipe structure for lowering the mass speed of circulating refrigerant. The precooling pipe 14 therefore covers the inlet pipe 11 and performs heat exchange, so that low pressure refrigerant is heated at the double pipe 20 part, and its temperature rises in the inlet pipe 11 from the time of coming out of the double pipe 20 until reaching compression mechanism 2. High pressure refrigerant is thereby prevented from being condensed.

Title: Multi-task executing device
Inventor: YOSHIDA KOICHI
IPC: G06F9/48
Filed: 1987-10-12
Abstract: PURPOSE:To execute the priority of plural tasks hourly and without waste with one microprocessor by operating the setting time of a counter and making a difference at the executing time of the tasks. CONSTITUTION:Until the value of a data register for a task executing time provided in respective register files A-D is set to a counter 3 and a counted value becomes the set value, one task is executed. When a counting value becomes the set value, the counter 3 generates a pulse and a next task is determined by a task designating circuit 4. The signal from a task designating circuit 4 is decoded by a decoder 5 and the register files A-D are switched so as to execute the next task. The priority between tasks can be executed only by making a difference for a register file for the value of the data register for the task executing time. Thus, without giving the burden to a user program, plural tasks can be executed with a time division by executing the priority for tasks with one microprocessor.

Title: Reciprocating piston machine
Inventor: RIEDLINGER HEINZ
IPC: F04B49/08
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To discharge pressure in a compression chamber in a short time after a reciprocating piston machine stops by providing a valve plate or a valve tongue piece on a discharge side and/or a suction side with at least one capillary passage as a pressure discharge connection part. SOLUTION: Valve plates 13, 14 of valves 9, 10 have capillary passages 18, 19 as pressure discharge connection parts so that a pump 1 can be restarted without load by reducing pressure which is left in a compression chamber 6 or vacuum when a diaphragm 1 stops. In this case, the capillary passage means a connection passage having comparatively and extremely small and close passage cross section. Although a certain degree of flow speed has to be generated first to form a return stream of gas, there is enough time for forming a gas stream which passes the capillary passages 18, 19 because the valves 9, 10 are closed after a reciprocating piston machine is shut off. Conseqeuntly, pressure compensation for environmental surrounding pressure is done in the compression chamber 6 in a short time, and the restart that the diaphragm 1 follows can be done without load.
