Title: Reserving apparatus
Inventor: MATSUMURA TAKANAO
IPC: H04N5/76
Filed: 1991-05-30
Abstract: PURPOSE:To reserve by designating a special external device and to control the special device. CONSTITUTION:A reserving apparatus is connected to recorders, and ID numbers of the recorders A, B, C, are sequentially set to 1, 2, 3. A controller 3 applies a command to an ID confirming output unit 6, which outputs an ID confirmation signal to an external device. The recorders A, B, C receive the signal and outputs an ID number of own device. An ID response input unit 7 receives ID response signals from the respective recorders, and transmits connections of the recorders of the ID numbers 1, 2, 3 to the controller 3. The ID number of the recorder to be desirably executed and a starting time are set by an operation unit 5, and stored in a reservation data storage unit. A reservation starting time is compared with a time of a clock 2, and when the times become equal, the controller 3 outputs an ID number signal and a record execution command. Thus, a special external device can be designated and reserved, and the special device can be controlled.

Title: Preparation of d-2-(6-methoxy-2-naphthyl)-propionic acid
Inventor: KIKAZAWA KAZUO
IPC: C07C67/00
Filed: 1978-10-18
Abstract: PURPOSE: To prepare the d-isomer of 2-(6-methoxy-2-naphthyl)propionic acid, useful as medicine, in high optical purity in an industrial scale, easily and economicaly by optical resolution of d,l-2-(6-methoxy-2-naphthyl)propionic acid with  L-(-)-α-phenylethylamine.  
     CONSTITUTION: d-2-(6-Methoxy-2-naphthyl)propionic acid expressed by the formula is prepared by optical resolution of d,l-2-(6-methoxy-2-naphthyl)propionic  acid with L-(-)-α-phenylethylamine. The resolution is carried out as follows. The acid and the amine (0.5W1.0mol on the basis of 1mol of the acid) are dissolved in a solvent. Preferably the solvent is the one which completely dissolves both compounds but poorly dissolves the formed salt, and a preferable example is the mixed solvent of methanol and ethyl acetate. The amine salt of the acid rich in the d-isomer slowly precipitates when the reaction solution is left to stand at room temperatures for 0.5W48hr. The product is further treated with the hot methanol- ethyl acetate mixutre to increase the ratio of the d-isomer, and the salt is decomposed to give the desired product.

IPC: H01L29/792
Filed: 1979-10-03
Abstract: PURPOSE:To permit high speed memory by setting negative electric potential to a substrate composing of memory at a lower value than a barrier level at the interface between the substrate and a gate insulating film wherein the storage of electrons at the trapping center in the gate insulating film is prevented. CONSTITUTION:An n<+> type source region 2 and an n<+> type drain region 3 are formed by diffusion on a p type Si substrate 1. And an SiO2 gate insulating film 4 having charge trapping center is formed on the substrate 1 exposed between the source region 2 and the drain region 3. A poly-crystalline Si gate electrode 5 is instlled on the SiO2 gate insulating film 4 to form a floating gate-type nonvolatile memory. In this composition, negative electric potential to the substrate 1 is selected at a lower value than a barrier level at the interface between the substrate 1 and the film 4. Namely, when the electric potential to the electrode 5 is VG, electric potential shown in a formula [I] is given to the substrate 1. Where: q is the quantity of electricity, phiso is a barrier level, tox is film 4 thickness. In this way, a threshold voltage will not fluctuate.

Title: Heat-cooking utensil
Inventor: ZUSHI SADAO
IPC: F24C7/02
Filed: 1982-07-22
Abstract: PURPOSE:To prevent a poor cooking result and to improve an operational stability, by constituting a heating chamber temperature detecting type automatic heat-cooking utensil such tat a heating section may be brought into suspended state upon a heating chamber temperature being raised to a preset upper limit that can affect on the heat-cooking result of foodstuff. CONSTITUTION:A heating chamber 2 has its temperature at the base plate 2b thereof detected by a heat sensitive element 21 and then inputted to a control section 10. The control section 10 functions to render a magnetron 4 inoperative upon a temperature 21 detected being elevated to a preset upper limit or more, and thereby preventing the utensil to cook automatically. By so doing, an infrared ray emitted from a foodstuff 6 can be correctly detected by a sensor 9 while a heat-cooking is carried out. As a result, a precise heating of the foodstuff 6 reflects on the improved cooking result of foodstuff. This also eliminates the chance of heating chamber to abormally raised state in its temperature, and thus improving an operational safety property.

Title: Photometric distribution control system of camera
Inventor: TSUNEKAWA TOKUICHI
IPC: G03B7/28
Filed: 1982-07-22
Abstract: PURPOSE:To obtain proper exposure at each of longitudinal and lateral positions, by providing a processing circuit which receives the output of a switch circuit operating according to a photographic attitude and excludes the contribution of a sky light measurement output to photometric arithmetic. CONSTITUTION:When a camera is held laterally, the contact of a switch PW1 is short-circuited by the gravity force of a conductive ball BL to turn off a gate G1. In this lateral state, the output of a light metering circuit LN1 for measuring sky light is applied to an operational amplifier OA1 through only a resistance RN1 to reduce the contribution rate of the circuit LN1 to the photometric arithmetic. When the camera is held longitudinally, on the other hand, the contact of a switch PW4 is short-circuited and the contribution rate of a circuit LN4 for measuring the sky light at the position is reduced.

Title: Exhaust apparatus of two cycle engine
Inventor: TOMITA TAKAO
IPC: F02B25/16
Filed: 1980-09-17
Abstract: PURPOSE: To reduce exhaust resistance and expedite exhaust, by forming a spirally twisted exhaust port on one side of central area of a cylinder so as to put combustion gas into circulation when the gas is exhausted.  
     CONSTITUTION: An exhaust port 3 is formed in such that the section between a laterally elongated opening 3a in an inner liner of a cylinder 1 and a longitudinal elongated opening 3b acting as a joint to an exhaust pipe on its outer side, may be formed in a spirally twisted intermediate conduit 3c. When an engine is operated and mixed air is exploded and burnt, and a piston 6 is pushed downward, the inner wall opening 3a of an exhaust port 3 is opened in order that combustion gas flows into the exhaust port 3 and then jets into an exhaust pipe after given circulation through the intermediate conduit 3c while increasing its velocity. Thereby, exhaust resistance is reduced and exhaust is expedited. Since discharge of burnt gas is promoted, fresh mixed gas can be charged smoothly into the cylinder 1 and the output of the engine can be thus increased.

Abstract: PURPOSE: To improve a semiconductor device in wet resistance by forming an Al film on the electrode part and an insulating film, and oxidizing the surface.  
     CONSTITUTION: An electrode 4 and an insulating film 6 on a semiconductor substrate are coated with an Al film 7, to which a metal wire 5 is connected. This is oxidized in O 2  to form Al 2 O 3  film 8 on the surface of the Al film 7.

Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To attain accurate positioning of an object by projecting a light for positioning for split image pickup and applying blink control to the light synchronously with the image pickup. SOLUTION: A spot light from four light emitting elements being components of a spot light projector 6 is projected on an object by a control signal from a spot light control circuit 7 when image pickup is started. The four spot lights in this case are projected to surround four corners of an area made narrower than an actual split image pickup range A by a prescribed overlapped area. In the case of picking up a succeeding split image pickup range B, the positions of the spot light at upper and lower parts at the right side in the case of picking up the preceding split image pickup range A are stored and a camera apparatus 3 is moved so that each spot light of upper and lower parts of the left side is overlapped onto the positions. Since the preceding split image pickup range A and the this split image pickup range B are matched, camera-shake is not almost caused.
