Title: Ac two-wire contactless switch
Inventor: TAKAHASHI FUMITO
IPC: H03K17/945
Filed: 1989-04-11
Abstract: PURPOSE:To enable the momentary conduction of a switch at every half cycle to be performed and to suppress voltage drop in a switching operation by providing a Zener diode between the base of a switching transistor and the collector of a sensor output transistor, and a diode between the base and emitter of the switching transistor. CONSTITUTION:A charging thyristor 14 is energized by turning off the switching transistor 12 by turning on the output transistor 6a of a sensor circuit 6, and causing a current flowing on the sensor circuit 6 flow from the output of a constant voltage circuit 5 to the gate of a charging thyristor 14. Simultaneously, the current is caused to flow on the gate of a main thyristor 4 via the output transistor 6a by detecting voltages at both ends of the sensor circuit 6 with the Zener diode 19, which energizes the main thyristor 4. In such a manner, it is possible to quickly energize the main thyristor 4 without being affected by the impedance and the temperature change of the sensor circuit 6, and to quickly charge a capacitor 7 connected in parallel with the sensor circuit 6 up to the voltage of the Zener diode 19, and to accelerate the operation of a switch, and to suppress the voltage drop.

Inventor: KOMADA HAJIME
IPC: A23B4/06
Filed: 1987-04-14
Abstract: PURPOSE:To reduce the flow-out of drip from frozen food and to enable uniform thawing of a frozen food, by thawing a frozen food at a low temperature and high humidity and subjecting the thawed food to tightening thawing treatment, thereby forming an ice layer on the surface of the food. CONSTITUTION:A frozen food is thawed at a low temperature (>=0 deg.C, i.e. about 2-8 deg.C) under high humidity condition (about 95-100%) and then subjected to tightening thawing treatment at a low temperature slightly lower than 0 deg.C, i.e. at about -3--1 deg.C under high humidity condition of about 90-100% to form an ice layer on the surface of the food. The flow-out of drip after the thawing operation can be inhibited by the ice layer. Consequently, the thawing of food can be carried out suppressing the deterioration of taste and the decrease in weight and keeping the quantity of the food in excellent state.

Title: Electronic scanning radar
Inventor: IZUMITANI TOSHIYUKI
IPC: G01S13/44
Filed: 1978-07-26
Abstract: PURPOSE:To shorten the beam scanning time, while holding the accuracy of an elevation, by setting a proper shift in a phase shifter so that the beam shape is expanded substantially in a Gauss shape. CONSTITUTION:In order to realize the vertical voer area 21 which is required for radar for scanning a pencil beam, in a low elevation region having the maximum covering distance, this region is covered with beams 40-1, 40-2 and so on having such beam width as are determined as small as possible by the aperture of an antenna. A high elevation region having short covering distance is made to have its beam width expanded as much as possible for the antenna gain so that the beam spacings are also expanded proportionally. As a result, a shift is set properly in a phase shifter by the command of a beam controller 11 so that the beam shape is formed into that of a Gauss function. As a result, the angle calculation can be simplified by the interporation of the beams, and the number of the beams in a vertical plane is reduced to shorten the scanning time.

IPC: G01N33/569
Filed: 1989-04-13
Abstract: PURPOSE: To detect presence of an antibody in a biological sample quickly by employing a specified diluent and aqueous cleaning composition. CONSTITUTION: A biological sample under suspicion of containing an antibody specific to some ligand is mixed with a diluent composition buffered to pH6-10 and containing a protein, a hydrocarbon, a surfactant and an organic compound charged negatively. The diluted sample is brought into contact with a ligand to produce an immunological complex of ligand and the antibody in sample and then an insolubilized complex is formed and separated from uncomplex substances using a microporous filtering membrane. Besides, the complex is brought into contact with an enzyme labeled antibody to form a labeled antibody-antibody-ligand complex and the insolubilized complex is cleaned using an aqueous cleaning solution buffered to pH5-10 and containing a surfactant thus removing the uncomplex substances.  Finally, a reagent composition is added to the insolubilized complex held on the membrane to form pigments thus determining whether the assay indicates the presence of ligand antibody in the sample.

Title: Method for disintegrating ceramic shell mold

IPC: B22C9/04
Filed: 1987-04-15
Abstract: PURPOSE:To prevent damaging of a product and to reduce the cost of shaking- out by immersing a casting mold after casting into an aq. alkali soln. of a prescribed concn. and temp. CONSTITUTION:The casting mold 3 is formed by forming a refractory layer 2 on the surface of a pattern 1, heating the pattern 1 at a prescribed temp. to expend the pattern and calcining the layer 2. A molten metal is then poured into the cavity 3a of the mold 3 and is cooled to cast a casting 4. The mold 3 and the casting 4 are thereafter immersed into the aq. alkali soln. 5 having <=50% concn. and the temp. above 50 deg.C and below the b.p. to disintegrate the mold 3 and to release the mold from the casting. Since no physical impacts are thereby applied to the product casting 4 at all, the damage of the product is surely prevented. Since the alkali concn. is relatively low, the stripping of the mold even from an Mg alloy casting is possible and since the time for the mold releasing is shortened, the cost of the mold releasing is reduced.
