Title: Production of optically active pantolactone
Inventor: SAYO NOBORU
IPC: C07B61/00
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound in remarkably high enantiomer selectivity and conversion by asymmetrically reducing a ketophantolactone in the presence of a transition metal complex containing a specific compound as a ligand. SOLUTION: This optically active pantolactone is produced by asymmetrically reducing ketopantolactone in the presence of a transition metal complex of 2,2'-bis(di-3,5-xylylphospholino)-5,5'-6,6',7,7',8,8'-octahydro-1,1'-b inaphthyl of formula I. The transition metal is preferably rhodium, ruthenium, iridium or palladium. The binaphthyl is obtained e.g. through processes comprising hydrogenating a 2,2'-dihalogeno-1,1'-binaphthy of formula II (X<1> is a halogen) in the presence of ruthenium-carbon catalyst, reacting the reaction product with metal magnesium, and subsequently condensing the obtained Grignard reagent with a di-3,5- xylylphosphinyl halide.

IPC: F25B5/02
Filed: 1990-10-16
Abstract: PURPOSE:To secure the humidity at the time when dehumidication is not necessary, by shifting a capacity for the defuminication if necessary, by a method wherein one circuit comprizing a first capillary tube, an evaporator and an electrically-controlled valve, and the other circuit comprizing a second capillary tube and an auxiliary evaporator are connected in parallel, and a flow resistance in the second capillary tube is made larger than that in the first capillary tube. CONSTITUTION:A refrigerant from a compressor 2 is sent into a condenser 3 and the heat of the refrigerant is radiated. After that, a refrigerant pressure is reduced in a first capillary tube 4 and the refrigerant is sent into an evaporator 5 and is evaporated and is returned into the compressor 2. A pipe line on the downstream side of the condenser 3 is split, and a circuit comprizing a solenoid valve 8, a second capillary tube 9 and an auxiliary evaporator 10 is connected to the suction side of the compressor 2, which is on the downstream side of an electrically-controlled valve 7. In this case, for example, a flow resistance caused by the refrigerant in the second capillary tube 9 is made four times as large as that in the first capillary tube. When the inside of a culture instrument is used at high humidity, the solenoid valve 8 is closed, and the opening of the electrically-controlled valve 7 is controlled, and thus the temperature of air in the inside thereof is controlled. When the inside thereof is used at low humidity, the solenoid valve 8 is opened and thus an evaporating temperature of the refrigerant in the auxiliary evaporator 10 is lowered and a capacity for dehumidication is secured.

Title: Ac signal generator
Inventor: KAWAMURA NOBUHISA
IPC: H03B27/00
Filed: 1992-10-16
Abstract: PURPOSE:To exactly output two AC signals in the relation of an arbitrary phase difference by digitally generating two waveforms and digitally generating the phase difference. CONSTITUTION:Digital data showing an amplitude value forming the AC signals is read out of a first waveform memory 11 by the operation of a first read means 10. A second read means 20 designates an address obtained by shifting addresses (DELTAt) corresponding to the phase difference theta which is set against the address which the first read means 10 reads, and it reads amplitude value data from a second waveform memory 13. Since the shift amount (DELTAt) of the read address is that corresponding to the phase difference theta which is set, amplitude value data forming the signal whose phase difference against the signal which is read out of the first waveform memory 11 is theta is read out of the second waveform memory 13.

IPC: G06F3/046
Filed: 1984-12-28
Abstract: PURPOSE:To obtain a position detector having high operability and high accuracy by detecting the maximum induced voltage level when a tablet part where plural magnetic plates and conductor plates are laminated by means of a position designating bar magnet. CONSTITUTION:A tablet part 100 is formed by laminating three sets of magnetic matters obtained by enclosing the warp and the weft woven into plain meaning into an insulated material and four sheets of conductor plates in the prescribed order and into a prescribed form. Then a point A of the part 100 is designated by a position detecting bar magnet 400 with its N pole turned down. Thus the induced voltage levels V1-V8 are obtained on the detection lines of the direction X. Each of these levels V1-V8 is maximum right under the point A. These voltage levels are obtained from a multiplexer 301 and therefore the X coordinate value with which the induced voltage level is maximum is calculated by a position detecting circuit 500 to obtain the X coordinate value XS at the point A. The Y coordinate value YS is also obtained in the same way.

Abstract: PROBLEM TO BE SOLVED: To calculate the distance to an object to be read without providing a distance sensor specially for a large-depth optical information reader which can reads optical information out of even an object at a distance from a read opening. SOLUTION: The reference image size Wst when there is a bar code Bst of size W at the read opening is represented as Wst=(L3/L2)W and image size Wo corresponding to a bar code Bo of size W at a distance L from the read opening is represented as Wo=(L3/(L1+L2))W, where L2 is the distance from the read opening to an image forming lens 34 and L3 is the distance from the image forming lens 34 to an optical sensor 36. The W's are erased from both the equations to calculate L1, which is then represented as ((Wst/ Wo)-1)L2. Here, L2 is a value characteristic of the device, so the distance L1 of the bar code Bo as an object of distance calculation from the read opening can be calculated by knowing Wst and No.

Title: Surface treating method
Inventor: HIRAOKA SUSUMU
IPC: H01L21/205
Filed: 1987-11-06
Abstract: PURPOSE:To preferentially selectively surface treat a section at which reactive substance is scarcely arrived by delaying the supply of reaction energy for a predetermined time from the supply of inactive reaction substance. CONSTITUTION:Inactive reaction substance 7 is injected from a pulse nozzle 1 toward a sample 2. When the nozzle 1 is closed in a state that the substance 7 is uniformly attracted to the surface of the sample 2, the removal of the substance 7 is started. The substance 7 of the section to be easily diffused is removed after a predetermined time, and the substance 7 is absorbed to the section to be scarcely diffused. Accordingly, a light is radiated from a pulse light source 6, here. After the substance 7 is activated and sufficiently reacted and the sample is sufficiently cooled, the nozzle 1 is opened and this process is repeated. Thus, a surface treatment can be selectively conducted in a section in which the supply of the reactive substance is not smoothly conducted due to the convenience of its shape.
