Title: Recording head for vertical magnetization
Inventor: MINO TETSUYA
IPC: G11B5/127
Filed: 1980-08-27
Abstract: PURPOSE:To reduce the external effects such as the change of temperature and humidty, the secular change, etc. and at the same time to form the head space with high accuracy, by forming plural main magnetic poles and auxilary poles on a single substrate. CONSTITUTION:Plural main magnetic poles 6 and auxiliary poles 7 are formed opposite to each other on a single substrate 8 of a silicon wafer, a glass substrate, etc. Then the current is flowed to a coil 10 to generate the magnetic field from the pole 7, and the short circuit is given to a coil 9 of the pole 6 excepting the poles 6 to which the magnetic recording is required. Thus the magnetic field is concentrated to the poles 6 having no short circuit to carry out the magnetic recording to a vertical magnetizing medium 4. The poles 6 having short-circuited coils 9 increase their magnetic resistance by the magnetic reaction function of the coil 9. As a result, the magnetic field is concentrated to the coils 9 having no short circuit. Thus the magnetized recording is possible on an optional track the recording medium 4.

Abstract: PURPOSE:To perform trouble diagnosing work of an LSI package readily and assuredly by enclosing an input and output terminal switching circuit in the inside of the LSI. CONSTITUTION:Terminals X, G, and P of each LSI are connected to common signal lines PP, GG, and XX.

Under this state, with the exception of the terminal X, G, and P, the LSI can be regarded as a single body. When the same inspecting pattern as that for single body inspection is applied on a terminal part 13 of the LSI by some way (e.g. IC clips), the quality of said LSI can be judged. The LSIs are sequentially inspected in this way, and the diagnosis of the LSI package is completed. In this constitution, the trouble diagnosing work which is the biggest bottleneck in the LSI package inspection can be simplified and assured.

Title: Combustion controlling device
Inventor: OKADA MAKOTO
IPC: F23N5/14
Filed: 1984-06-08
Abstract: PURPOSE:To prevent the evaporating capacity from lowering by raising the temperature of the evaporating device to vaporize liquid fuel such as kerosene and the like when the ambient temperature is low by a method wherein the temperature of the evaporating device is made variable in response to the temperature of the liquid fuel or of combustion air. CONSTITUTION:When the atmospheric temperature is low and consequently the temperatures of combustion air and of fuel are also low, the temperature of an evaporating device drops abruptly. As a result, the resistance of a thermistor 9 increases until a voltage comparator 22 inverts itself, resulting in energizing an electric heater 33. However, in this case, incomplete combustion may occur due to the lowering of evaporating capacity before the temperature of the evaporating device 5 is restored. In order to eliminate the fear of occurrence of above- mentioned incomplete combustion, a temperature detector 10 installed near the lead-in port of combustion air is set so that its contact closes when the ambient temperature lowers below the set value. As a result, the non-inversion side input voltage of the voltage comparator 22 is higher than that of the comparator 22 at the time when the contact of the temperature detector 10 is open, because a voltage divided by the resultant resistance value of a resistor 12 and a resistor 13 connected in parallel to each other and the resistance value of a resistor 21 is given to the non-inversion side of the comparator 22. Accordingly, the voltage comparator 22 does not invert until said voltage lowers below the voltage developed by the resistance value of a thermistor 9. As a result, the temperature of the evaporating device 5 becomes higher, resulting in enabling to prevent incomplete combustion from occurring.
