Title: Hetero junction field-effect transistor
Inventor: FUCHIGAMI NOBUTAKA
IPC: H01L29/812
Filed: 1993-01-12
Abstract: PURPOSE:To realize a high speed and low noise by providing an undoped semiconductor layer wherein energy level of a conductive band is lower than energy level of a channel layer between a channel layer and a barrier layer at a specified thickness. CONSTITUTION:An i-InAlAs buffer layer 7 and a p-InGaAs buffer layer 6 are formed on an InP substrate, and an n-InGaAs channel layer 1, an i-InAs carrier storage layer 2, an i-InAlAs barrier layer 3 and an i-InGaAs cap layer 4 are formed thereon at thicknesses of 15, 1, 10, and 5nm, respectively. After a gate electrode 9 is formed and a surface thereof is coated with an SiO2 film 8, the SiO2 film 8 is removed only in an ohmic layer formation region. The channel layer 1 in the ohmic layer formation region is etched using the SiO2 film 8 as a mask.

Title: Safety circuit for electric heating equipment
Inventor: YONEDA SEIJI
IPC: G05D23/24
Filed: 1991-01-16
Abstract: PURPOSE:To enhance safety by providing two independent temperature detecting circuits which are so constituted as not to be mutually affected. CONSTITUTION:A device is equipped with a first temperature detecting circuit 1 which detects the temperature of a heating wire 11 based on the terminal voltage of a heat sensing wire 12, and with a second temperature detecting circuit 2 which detects the temperature of the heating wire 11 based on current flowing in the heat sensing wire 12 through a current transformer CT. Since the input impedance of the current 1 is set in advance greater than that of the heating wire even if the impedance of the first temperature detecting circuit fluctuates because of the failure of the circuit 1, current flowing in the current transformer CT is not affected, current can thereby be cut off based on the output of the temperature detecting circuit 2 in case of an abnormal condition. In addition, even if the temperature detecting circuit 2 fails while its input impedance fluctuates, the current fluctuation of the primary circuit of the current transformer CT is negligible, the detected voltage of the temperature detecting circuit 1 is not thereby affected because the heating wire is connected to the temperature detecting circuit 1 via the current transformer CT, current can be therefore cut off based on the output of the temperature detecting circuit 1 in case of an abnormal condition.

Title: Recording method
Inventor: KIHARA NOBUYOSHI
IPC: H04L7/08
Filed: 1979-01-12
Abstract: PURPOSE: To ensure the accurate detection for the synchronous signals with a simple system by securing the parallel recording for the signals received the digital conversion with every bit and at the same time deciding the synchronous signal pattern according to the occurrence frequency of the high and low levels which form the bit signals.  
     CONSTITUTION: With conversion of the analog signal A into the n-bit digital signal, the level relation to the n-bit analog signal features as (1/2 n )×VPP (VPP: maximum analog input voltage). Thus the repetitive synchronism is accelerated more and more between high level 1 and low level 0 toward the lower bits. These n-bit digital signals are recorded in parallel onto the track T 1  and so on of the magnetic tape or the like and with every bit, and the synchronous signals of the pattern of more repetition between levels 1 and 0 are applied to the higher-rank bit with the pattern of less repetition applied to the lower-rank bit respectively in accordance with the occurrence frequency of the high and low levels and with every frame F into which several data are collected. As a result, the probability of the occurrence of both the synchronous signal and the data in the same pattern can be reduced, thus securing the accurate detection for the synchronous signals with a simple system.

Title: Load detector
Inventor: TAKAGI KATSUYUKI
IPC: G01B7/00
Filed: 1993-01-12
Abstract: PURPOSE:To increase an output sensitivity to a load input and to improve a detecting precision by a method wherein the strain detecting direction of the other opposite set of resistor thick films is made to intersect a load detecting direction and also a gage factor is made small. CONSTITUTION:Resistance values R2 and R4 of lateral-direction resistor thick films 6c2 and 6c4 increase from initial values under a compression load when a gage factor is 2.6 or below, for instance, and decrease from the initial values under the compression load when the gage factor is above 2.6. Accordingly, the gage factor of the two thick films 6c2 and 6c4 of which the strain detecting direction intersects the load detecting direction perpendicularly is set at 1.5 to 2.0 being lower than 2.6, while the gage factor of longitudinal-direction resistor thick films 6c1 and 6c3 is set at 7 to 10 being higher than 2.6. In this way, a large output voltage e0 can be obtained, as a Wheatstone bridge circuit, for a compression load input received by a strain generating body 6a. In other words, the output sensitivity to the load input is increased.

Title: Distributed feedback semiconductor laser
Inventor: ABE HIROAKI
IPC: H01S5/042
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To make an electric current injected into projecting strip sections formed on the surface of an upper clad layer to be efficiently supplied to the oscillating area of an active layer without circulation to other parts than the projecting strip sections by forming a contact layer only on the projecting strip sections. SOLUTION: A clad layer 13, an active layer 14, a clad layer 15, a contact layer 16 are successively formed on a substrate 12 in this order and projecting strip sections 19 are formed by removing both side parts of the layers 15 and 46. In addition, a diffraction grating is composed of forming a regular recessed section 19a between the strip sections 19. Since a current is given to an oscillating area β from an electrode 18 through the contact layer 16 and the strip sections 19, the current hardly flows to other parts than the area β. In addition, since the diffraction grating is formed of the recessed section 19a immediately above the area β, the resonance effect of waves becomes higher in the area β.

Abstract: PURPOSE:To constitute the title manufacture so that falling down of hairs which have been generated by adhering closely an ornamental component to the surface of a vacuum mold hardly occurrs, by bearing the ornamental component under a floating state in air by a needle-like protrusion provided on the vacuum mold in a standing state. CONSTITUTION:An ornamental component 10 is mounted on a needle-like protrusion 28 of a vacuum mold 12 so that a surface material 20 confronts with the needle-like protrusion 28. In this instance, the ornamental component 10 is under a state wherein the surface material 20 is born by the needle-like protrusion 28 and floated in the air slightly above the surface 23 of a mold 12. In addition to the above, as the ornamental component 10 is bonded with pressure so as to reduce thickness of the same at he edge part of the same, a larger space than the other part is formed between the vicinity of the edge 22 and the surface 23 of the mold. The surface, therefore, of the ornamental component is born by the needle-like protrusion or a back material is born by the same by striking against the back material even if the same pierces through the surface 20 and a matter that the surface material 20 is bonded to a mold surface with pressure is prevented.
