Title: Semiconductor integrated circuit
Inventor: NOMURA YOSHINOBU
IPC: H01L27/082
Filed: 1987-10-19
Abstract: PURPOSE:To produce an output signal having larger amplitude by producing an output from an IIL basic element having large breakdown strength between an emitter and a collector by a bipolar linear circuit. CONSTITUTION:A most logic circuit is composed of a first IIL basic element 40, and a second IIL basic element 41 having a second base region 47 of higher impurity concentration than that of the base of the element 40 is formed in an island 43 formed with the element 40. The element 41 is inserted between the element 40 and a bipolar linear circuit 57 to produce an output from the element 41. As a result, since the value of a breakdown strength between the emitter and the collector of the inverter transistor 2 of the element 41 can be increased larger than that of the transistor 2 of the element 40, an output signal having larger output amplitude is produced.

Abstract: PURPOSE:To reduce cost of coating materials using a simple coating method by coating the surface of a granular fertilizer with a coating material consisting of a carboxyl group-containing thermosetting resin and platelike filler. CONSTITUTION:The surface of a granular fertilizer is coated with a coating material (volume concentration of the filler; 5-25%) consisting of a thermosetting resin having carboxyl groups at the terminals, e.g., a resin consisting essentially of an alkyd resin, and a platelike filler selected from talc, sericite and muscovite to provide a coated granular fertilizer. The shape of the platelike filler is especially preferably flaky (>=2, especially >=10 ratio of particle diameter/thickness) and the particle diameter thereof used is normally 0.5-50mum. The above- mentioned coated granular fertilizer is produced by dripping or spraying a solution prepared by dispersing the thermosetting resin and platelike filler in a granular fertilizer in a fluid or tumbled and heated state.

Title: Toaster oven
Inventor: YAMAGUCHI SHIGEKI
IPC: A47J37/08
Filed: 1986-11-05
Abstract: PURPOSE:To improve the safety of the oven by backing up the toaster performance by a thermostat controlling the oven performance. CONSTITUTION:A changeover switch 6 can be switched to the position of the toaster and that of the oven. When the changeover switch 6 is set at the position of the toaster, a damper 15 is pressed by a projection of a damper cam 19 and is rotated to open a guide port 12 of heat for a roasting degree sensor 13. When the temperature of a roasting chamber 2 is high, the output of a comparator 47 is quickly reversed and power supply switches 32a and 32b are quickly opened, thus the roasting degree constantly becomes a predetermined roasting degree. When a circuit fault is generated and the comparator 47 is not reversed, the temperature within the roasting chamber 2 increases extraordinarily. Then, the thermostat 20 operates to turn OFF a transistor 49, power supply to a solenoid 43 is stopped, and power supply to respective heaters 7 and 8 are also stopped. Thus, the safety of the toaster oven can be improved.

The dielectric layer prevents deterioration of recording properties by deforming the base and recording layer by heat at the time of recording and the same is a thin film of ZnS, SiO. The reflective layer is a thin film of a metal of Al or Au or an alloy of them with Ti or Cr. Recording is performed by forming amorphous recording mark by applying a laser beam pulse to a recording layer having a crystalline state.

Filed: 1987-10-20
Abstract: PURPOSE:To bring a smooth circle to plot at high speed by giving a gradation conforming to a distance between each picture element being in the vicinity of a circle and the circle, to each picture element. CONSTITUTION:When the radius of a circle is denoted by R, the center is set as an origin and coordinates of a picture element are denoted by X, Y, whether the picture element exists at the inside of the circle or at the outside can be decided by evaluating positive or negative of X<2>+Y<2>-R<2>. By utilizing such expression, coordinates of two picture elements for placing the circle between them in the X axis or Y axis direction can be derived. Also, in order to execute anti-aliasing, it is necessary to derive a distance between the picture element and the circle, but since it takes a time for calculating a square root, the following expression which is deformed the previous expression is used. D=¦(X<2>+ Y<2>-R<2>)/(2R)¦ A value of this expression is different from the distance, strictly speaking, but it can be regarded as the distance in case of a range of 0<D<1. Therefore, by utilizing this expression, selection of the picture element and a determination of its gradation are executed. In such a way, a smooth circle can be brought to plot by a small quantity of calculation.
