Abstract: PROBLEM TO BE SOLVED: To obtain a racemic carboxylic acid useful as an intermediate raw material for medicines and agrochemicals in high yield by reducing the amount of a base used and racemizing an optically active carboxylic acid under mild conditions. SOLUTION: The racemizing reaction of an optically active carboxylic acid represented by the formula (R<1> and R<2> are each hydroxyl, a 1-10C alkyl, a 6-10C aryl, a 7-11C aralkyl or a 5-6C cycloalkyl; X is H or an alkali metal) or an alkali metallic salt thereof is carried out in the coexistence of a base (e.g. potassium hydroxide) and dimethyl sulfoxide at 60-130 deg.C for 0.1-40hr. The base is used in an amount of 1.01-10 equiv. based on the optically active carboxylic acid and 0.01-9 equiv. based on the alkali metallic salt of the optically active carboxylic acid. The dimethyl sulfoxide is used in an amount of 0.1-10 times based on the optically active carboxylic acid (alkali metallic salt). An organic solvent (e.g. cyclohexane) and water may coexist in racemization.

Title: Feeding-out device hot water in jar pot
Inventor: NAKAO YOSHITADA
IPC: A47J27/21
Filed: 1987-12-11
Abstract: PURPOSE: To improve safety by controlling the hot water discharging device in such a manner that, when a hot water discharging key is pressed, if the water is sufficient, hot water may be normally pumped out, and when the hot water discharging key is depressed, if the water is insufficient, the hot water may not be pumped out. CONSTITUTION: When a hot water discharging key 7a is depressed, the output 7b becomes high, and a base current is supplied to a transistor 9d through a resistor 9c, and the transistor 9d can be turned on. Then, since a motor 4 and the transistors 9b, 9d are serially connected, the motor 4 rotates only when the transistor 9b and the transistor 9d are on at the same time. That is, only when the hot water discharging key 7a is depressed under a state wherein hot water has not decreased to a degree that a water level detector 8a is exposed, the motor 4 rotates to drive a pump 5, and the hot water is pumped out. Then, when the water level detector 8a is exposed, even if the hot water discharging key 7a is depressed, the motor 4 does not rotate, and the hot water is not pumped out.

IPC: H04N21/435
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To enjoy multimedia line service while utilizing a personal computer popular in general home without applying any remarkable specification change. SOLUTION: Multimedia data are received and supplied to a board 2 as a bit stream. On the board 2, image and audio data and other general data are separated from the bit stream based on an ID for each packet. The image and audio data are recorded in a storage B composed of an attachable and detachable large capacity recording medium as a stream B together with the recording position information of data. Information corresponding to the recording position in the stream B is contained in the general data, defined as a stream A and recorded in a storage A composed of an HDD. A user performs the retrieval of data to the storage A and performs the actual reproduction of image and audio data from the storage B. Since the large capacitance data and interactive data are separately recorded, the multimedia service can be enjoyed while utilizing the existing personal computer.

Title: Soldering method by light beam
Inventor: WATANABE MASAKANE
IPC: B23K26/082
Filed: 1994-11-24
Abstract: PURPOSE: To provide a highly stable and reliable soldered connection. CONSTITUTION: In the case a transparent softening material is put between a transparent presser glass plate 3 and a substrate 2. the pressure applied to the glass plate 3 is dispersed due to the transparent softening material 6 and even if there is more or less unevenness in a connection terminal part, pressure is applied uniformly to the substrate 2 and the connection terminal part can be attached closely to the substrate and a solder is spread sufficiently. In the case the transparent softening material 6 is in the connection terminal side and has a cross section shape with a small surface area, the pressure is converged on the connection terminal, so that the pressing does not loosen.  Moreover, by using a mechanism for pressing which applies pressure to the glass substrate while shifting the pressure applied part of the glass substrate in the periphery of the area to which laser is radiated, the part to which laser is radiated is always pressured and thus the pressure at the time when a solder reflows does not become weak.

Title: Disk driving device
Inventor: HAYASHI MITSUHIRO
IPC: G11B11/105
Filed: 1994-12-20
Abstract: PURPOSE: To improve a detection speed by correcting a discrimination value for discriminating the information on '0' or '1' of the PEP signal read out of a PEP region in accordance with the detection output of a number-of- revolution detecting means. CONSTITUTION: A reproducing means 109 reproduces the information of the PEP region in accordance with the discrimination value corrected by a correcting means 112. Then, the PEP signal is eventually reproduced in accordance with the adequate discrimination value according to the number of revolution of a disk 101 even in an acceleration period after the disk starts rotating before the disk attains stationary revolution. The exact reproduction of the information from the signal of the PEP region of the disk 101 is, therefore, made possible during the acceleration period after the disk starts rotating before the disk attains stationary revolution. The detection speed is thus made higher than heretofore.

IPC: G11C11/401
Filed: 1990-11-20
Abstract: PURPOSE:To enable accurate synchronous operation by selecting a synchronous clock inputting first and second control signals to make an X address latch signal and a Y address latch signal. CONSTITUTION:First and second control signals are latched with first and second conduction type latch circuits 11 and 12 respectively based on a synchronous clock.

Title: Cylinder device for compressor capable of tightly fixing position of keeper
Inventor: KO MEIJU
IPC: F04B39/10
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To correctly maintain the position of a keeper even if a compressor is used for a long time by forming a fixing hole on the keeper, and arranging a fixing projection for tightly fixing the position of the keeper on a valve plate by connecting to the fixing hole. SOLUTION: Fixing holes 93 are formed on both side edge part regions of a keeper 91. A pair of fixing projections 99 for inserting into the fixing holes 93 are formed on a bottom surface of a first recessed part 41 of a valve plate 31. The fixing projections 99 are formed so as to have rectangular cross sections respectively, and the fixing projections 99 and the fixing holes 93 are tightly connected to each other. By the fixing projections 99 are connected to the fixing holes 93, the position of the keeper 91 is tightly maintained in the first recessed part 41. The position of the keeper 91 is not changed by vibration transmitted from a discharge valve lead 71 to the keeper 91, abrasion of the keeper 91, and the like even if a compressor is used for a long time.  It is thus possible to prevent the positions of a stopper 81 and the discharge valve lead 71 from changing, and it is also possible to prevent reduction of an efficiency of the compressor.
