Filed: 1992-04-14
Abstract: PURPOSE:To obtain a lightly cookable food free of heating unevenness in thawing by arranging cooked rice, formed and frozen in the form of a block on a heat-resistant sheet, further placing a thin sheetlike formed and frozen side dish having grooves or unevennesses in the longitudinal and/or transverse directions on the surface thereon and filling the side dish in a bag. CONSTITUTION:Cooked rice 2, formed and frozen in the form of a block is arranged on a heat-resistant sheet 5. A side dish 3, formed and frozen in a thin sheetlike form and having grooves 6 on the surface, e.g. curry sauce is placed thereon and the whole is filled in a bag 4 and sealed. In eating, the food is directly thawed and heated with a water bath or a microwave oven. The bag may be unsealed and the food may be directly eaten from the bag or taken out of the bag 4 with the heat-resistant sheet 5 and eaten. Since the food has the constitution, the side dish 3 is quickly thawed and heated. Since the cooked rice 2 is in the form of the block, warm curry and rice, etc., can lightly and tastily be eaten without overheating and causing unevenness.

Title: Pressure reducing valve
Inventor: MORINO KENJI
IPC: G05D16/10
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a simple valve structure equipped with a high pressure side oil pressure selecting function and a function as a pressure reducing valve by adopting a pressure reducing valve and a shuttle valve. SOLUTION: This pressure reducing valve is provided with a high pressure selecting function to be used as the signal pressure and/or driving pressure of an oil pressure control circuit and a pressure reducing function. Either an oil pressure introduced to a first input port 12a or an oil pressure introduced to a second input port 13a, which is higher, allows a center spool 16 to move to one side, and an oil pressure is generated in an output port 15a, and first and second pistons 19 and 20 are moved to the center.  At that time, the oil pressure of the output port 15a is allowed to act on the piston in the pressure chamber whose input pressure is lower of first and second pressure chambers, and the piston is closely brought into contact with the end face of the center spool 16, and returned to the initial neutral position together with the center spool 16 according to a differential pressure based on a difference between the cross-sections of the piston and the center spool 16. Then, the reduced output pressure is generated in the output port 15a according to the pressure balance at that time.

Title: Dc regenerative circuit
Inventor: TATEDA YOSHIFUMI
IPC: H03K5/007
Filed: 1977-11-15
Abstract: PURPOSE: To attain the DC regeneration of a fine signal stably avoiding the temperature drift due to a transistor, by detecting the peak of the output voltage of a DC amplifier after the comparison with a reference voltage and amplification and by feeding it back to the input side of the DC amplifier.  
     CONSTITUTION: Input signals after its DC components are removed by capacitor 1 are applied to transistor Tr3 at its base, thereby extracting low-impedance output signals. This output signal is compared with reference voltage 6 and amplified by amplifier 10 and after its peak is detected at the time constant determined by diode 11, capacitor 12 and resistor 13, it is inputted to the base of transistor 3 by way of diode 2 to fix its base bias. The temperature dirft of the DC component regenerated by the circuit like this depends upon the input dirft of amplifier 10 if the gain of amplifier 10 is large, and it is under no influence of characteristics of Tr3. Further, the temperature drift of amplifier 10 can be decreased, so that stable DC regeneration can be attained.

Title: Stabilizer for wavelength of semiconductor laser
Inventor: KAEDE KAZUHISA
IPC: H01S5/0625
Filed: 1984-07-03
Abstract: PURPOSE:To prevent the variation of oscillating frequency even when the number of carrier electrons injected to an active layer is changed by applying control currents to a second electrode so as to deny the variation of the optical resonator length of a semiconductor laser element generated by applying modulation signal currents to a first electrode. CONSTITUTION:When currents are injected to an active layer 201 through a first electrode 213 and a common electrode 212, a laser is oscillated by a resonator formed by a diffraction grating 204 and a second cleavage plane 219. When a modulation signal is applied to the first electrode 213 for modulating the intensity of laser oscillating beams at that time, the optical length of a region just under the first electrode 213 in the active layer 201 changes. Since a control signal altered in response to the change of the modulation signal is applied to a second electrode 214, however, a refractive index varies only by a section compensating a resonator change generated by the refractive-index change of the active layer region just under the first electrode 213 in a region just under the second electrode 214 in the active layer 201, thus keeping resonator length constant as a whole.

Title: Curable unsaturated alkyd and its production
Inventor: TAKIYAMA EIICHIRO
IPC: C08F299/00
Filed: 1985-06-26
Abstract: PURPOSE:To obtain an unsaturated alkyd resin excellent in workability, water resistance and chemical resistance, by reacting an epoxy resin with a specified amount of xylenol and esterifying the hydroxyl groups of this product with an alpha,beta-unsaturated polybasic acid. CONSTITUTION:An epoxy resin of formula I is reacted with xylenol in an amount sufficient to eliminate the epoxy groups of this epoxy resin to form a reaction product of formula II. The hydroxyl groups of this reaction product are esterified with an alpha,beta-unsaturated polybasic acid or its anhydride to obtain the purpose unsaturated alkyd of formula III. In the formulae, R1 and R2 are each H or methyl, n is 0-2 and m is 2-20. Because said unsaturated alkyd has dimethylphenoloxymethylene groups as side chains, it is bulky and is low in a content of double bonds per unit MW, which will advantageously affect the boiling water resistance and heat distortion temperature of the resin.
