Inventor: SCHLOEMER GEORGE C
IPC: C07C233/11
Filed: 1990-02-28
Abstract: Pharmaceutically useful optically active  alpha -arylalkanoic acids of the formula <CHEM> where Ar is aryl and R1 is alkyl or cycloalkyl or esters, ortho esters, or amides thereof are stereoselectively prepared by contacting a reagent of the formula Ar-MX, (Ar) 2M or ArM' where M is Cd, Cu(II), Mn(II), Mg or Zn, and M' is Cu(I) or Li, and X is halogen, with an optically active compound of the formula <CHEM>  where Z is a leaving group and Y is halogen, acyloxy or <CHEM> where R' and R'' are alkyl, aryl or with N are a heterocyclic group, to form the optically active ketone of the formula <CHEM> which is ketalized and rearranged to said acid, ester, ortho ester or amide. Alternatively, said ketone is reduced to the corresponding alkanol, which is rearranged to the  alpha -arylalkanal. The alkanal so produced is converted to said acid by conventional methods.

Title: Direct-injection type diesel engine
Inventor: NAKAO HIROHIDE
IPC: F01L1/053
Filed: 1984-03-16
Abstract: PURPOSE:To secure each of large suction and exhaust port areas without entailing any drop in a compression ratio, by setting up a fuel injection nozzle centering on a cylinder, and also setting up both suction and exhaust valves to be driven by separate cam shafts symmetrically at both sides of the said nozzle, with them tilted a little. CONSTITUTION:In case of a direct-injection type Diesel engine, a fuel injection nozzle 8 is set up in the centershaft position of a cylinder, while a suction valve 13 and an exhaust valve 15 both are set up symmetrically at both sides of the nozzle 8 with a slight gradient to a cylinder axis. Each two of these suction and exhaust valves 13 and 15 are installed in one cylinder so that each of large suction and exhaust ports can be formed up. These suction and exhaust valves 13 and 15 are opened or closed by separate cam shafts 33 and 35. A tilt of each stem of these suction and exhaust valves is able to be held down to small enough whereby capacity in a concavity at the lower surface of a cylinder head 2 is well reducible, thus large suction and exhaust port areas are securable without entailing any drop in a compression ratio.

Title: Drain tool
Inventor: HAMAZAKI KOJI
IPC: E03C1/12
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a drain tool, by setting the upper face of the drain tool higher than the floor face so as to protrude it from the floor and providing a water way connected to the drain opening at the side face of the drain tool. SOLUTION: A recessed part 2a to lay decorative matericals T like tiles is formed on the upper face 2 of a drain tool 1. When decorative materials T are fixed onto the recessed part 2a with an adhesive, a plurality of pierced holes 4 are formed in the recessed part 2a in order to increase the adhesive strength and also water permeable holes 5 are formed at the side face 3 of the drain tool 1. The height of the side face part 3 is set so that the upper face 2 projects from the floor face (f) when the drain tool 1 is installed in the draining part of the floor F. Drain discharged on the floor face (f) flows into the drain tool 1 sideways from the water hole 5 and flows out from the drain opening 11 to a drain pipe 13 through a trap 12. Accordingly, since the upper face 2 is stuck out of the floor face (f), it is not trodden by users and hence, it is prevented from the deformation.

IPC: H03M3/04
Filed: 1984-03-15
Abstract: PURPOSE:To reduce deterioration is sound quantity when a bit error occurs on a transmission line and to maintain high sound quality by using an orthogonal estimating device as an adaptive estimating device for diverse ADPCMs. CONSTITUTION:A sound signal which is sampled and digitized is inputted at a transmission side from a terminal 1, a subtracter 10 calculates the difference between the sound signal and an estimated value, and a quantizer 20 performs quantization and outputs the result to a terminal and a reverse quantizer 30. The reverse quantizer 30 decodes the quantization result and an adder 40 calculates the sum of the decoded value and estimated value and outputs the sum to an estimating device 50. The estimating device 50 performs the orgothonal conversion of the decoded signal and multiplies the result by a coefficient which varies successively and adaptively to perform reverse conversion, and calculates an estimated value on the basis of the reverse conversion result and outputs the value. At a reception side, the quantization result inputted from a terminal 3 is applied to a reverse quantizer 31 to generate a decoded value. This decoded value coincides with that of the transmission side when there is not bit error. An adder 41 and an estimating device 51 perform exactly the same operation that the adder 40 and estimating device 51 perform. The output of the adder 41 is outputted as the output signal of the reception side from a terminal 4.

IPC: H01H36/00
Filed: 1983-03-25
Abstract: PURPOSE:To detect securely and safely the touch of a human body by using an oscillating circuit which is normally in an oscillation state and stops oscillation by variation in its input impedance once the human body touches a contact plate. CONSTITUTION:When the human body touches the contact plate 20, a signal is inputted to the oscillation circuit 21 through an input resistance 33 and the oscillation stops. Then, the output V1 of the circuit 21 is passed through a band- pass filter 22 to obtain an output V2, which is compared with a comparison voltage VS by a comparing circuit 23, whose output V3 is inputted to a smoothing circuit 24. The output V4 of the circuit 24 becomes smaller than the predetermined trigger voltage of a one-shot circuit 25, whose output voltage V5 becomes a positive bus voltage P for a predetermined time, so that a driving transistor 35 generates a detection output. Therefore, there is no electric shock because no AC bias is used, and the detection signal is obtained securely for the specific time in high safety without any electrostatic shock.
