Title: Semiconductor device
Inventor: ASAMI SEISUKE
IPC: H01L29/78
Filed: 1982-12-17
Abstract: PURPOSE:To contrive accomplishment of high integration of an IC by a method wherein, on the epitaxial layer of a semiconductor substrate, a bipolar transistor and a CMOS transistor are provided on the same substrate. CONSTITUTION:As a P-channel transistor 50 of CMOS is provided on an N type epitaxial layer and an N-channel transistor 51 of CMOS is formed on a semiconductor substrate 22 consisting of P type silicon, the formation of a P-well is unnecessitated, and the epitaxial layer of 4-5mum thickness located under the P-well to be used for prevention of latchup phenomenon, which was required before, can also be unnecessitated. Accordingly, the epitaxial layer itself can be thinly formed, and as a result, an oxide film isolation method, which is not used when a thick epitaxial film is used, can be used and besides, the width of an isolation region can be narrowered.

Title: Field effect transistor
Inventor: UMEMOTO YASUNARI
IPC: H01L21/338
Filed: 1985-10-07
Abstract: PURPOSE:To suppress multiplying effect of carriers, by providing a state, wherein holes do not remain in a substrate, i.e., a state, wherein the quick flow of electrons into the side of a drain can be controlled. CONSTITUTION:Flow of electrons 20, which are generated in a semi-insulating GaAs substrate 11, into the drain side is blocked by a P-type impurity doped layer 18, which is a potential barrier for the electrons. Flow of simultaneously generated holes 21 into the source side is blocked by an N-type impurity doped layer 19, which is a potential barrier for the holes. Therefore, only the holes do not remain in the substrate, but both electrons and holes remain. With the elapse of time, both electrons and holes are recombined and disappear. Thus the multiplying effect of carriers generated by the input of alpha rays can be suppressed.

Abstract: PURPOSE:To enable a correct detection of filter stuffing and an appropriate response thereto by providing a dryer for clothes with a control means having such a construction that, when the air pressure in a drying room is detected to be higher than a predetermined one, it can appropriately respond to detection results. CONSTITUTION:In drying of clothes to be dried, waste thread scattered from the clothes is caught by a lint filter 8 and gradually attached thereon. If the lint filter 8 is not cleaned, the mesh of the filter 8 is stuffed with the waste thread and air pressure inside a drum 4 rises up. As a result, a diaphragm 24 of an air pressure sensor 21 is pressed from the inside to the outside of the drum 4, which makes a magnet 25 come near a reed switch 26. Thus the read switch 26 is operated to provide detection signals about the air pressure in the drum 4. If the detected value is judged to be higher than a predetermined one, the sensor 21 operates an alarm means to provide alarm signals to tell that the lint filter 8 is in the stuffed condition, and stop electric supply to a motor 18 and heater 14, thereby interrupting the drying operation.

IPC: B06B1/04
Filed: 1989-08-29
Abstract: PURPOSE:To prolong the life of an exciter by forming a shaft body as a hollow body and providing a heat pipe in the hollow part of the shaft body. CONSTITUTION:Yokes 5, 5' in contact with the respective magnetic poles of a magnet 4 are fixed in a cylindrical part 1b of a housing 1 and a coil 6 is mounted on the outer periphery at the front end of a skirt part 21 of the shaft body 2.

This heat is absorbed by the evaporation of working fluid. The latent heat thereof is radiated by a heat sink 2b. The life of the exciter is prolonged without impairing the function of the magnet in this way.

Title: Method for determining threshold level
Inventor: ISHIBASHI MASAHIRO
IPC: G11B7/00
Filed: 1988-09-06
Abstract: PURPOSE:To correctly discriminate the presence/absence of a writing signal by relating two parameters of inclination and offset to read powers, tabling them and obtaining a threshold level by an arithmetic operation. CONSTITUTION:On an offline, a minimum signal level and a maximum noise level in the read powers of a measured disk are measured beforehand and a SIG ON level (threshold level relating whether it is regarded as a signal or as a noise) is set between the read powers. This SIG ON level is approximat ed to the linear function of the read power and the two parameters of the inclination and the offset are related to the read powers and they are tabled. At the time of an online processing to measure the signal of the optical disk, the set read power is read and the SIG ON level is obtained by the arithmetic operation by referring to the corresponding inclination and offset. Thus, the presence/absence of the writing signal can be correctly decided.
