Filed: 1986-06-30
Abstract: PURPOSE:To obtain stable breakdown strength by each overlapping a gate electrode and a through-layer electrode up to the upper section of a substrate region through a surface insulating film and forming both electrodes. CONSTITUTION:Gate electrodes 8 overlapped onto an N-type semiconductor substrate 1 are shaped to a P-type diffusion layer 4 and electrodes 9 overlapped onto the N-type semiconductor substrate 1 to a through-diffusion layer 3 respectively. When a bias is applied in the forward direction at that time, a depletion layer is spread as shown in a dot-dash line (a) on a low bias, and the gate electrode 8 functions as the so-called field plate, and the depletion layer is extended as shown in a broken line (b) on a high bias, and the depletion layer is inhibited by the voltage of the through-layer electrode 9 on the surface and the depletion layer is not spread to an outer circumferential section more than before. Accordingly, stable breakdown strength is acquired without being largely affected by the film quality of an insulating film and the variation of the film quality.

Title: Hydraulic control device for automatic transmission
Inventor: FUJIWARA TAKUJI
IPC: B60W10/10
Filed: 1986-06-30
Abstract: PURPOSE:To prevent the occurrence of a shock due to a fact that a line pressure is excessively higher than an engine output, by a method wherein correction control is effected in a manner that, by means of a line pressure correcting means, a line pressure set by a line pressure set means is decreased over that during running on lowlands. CONSTITUTION:In a pressure regulating valve 52, a bellows 91 is positioned to the end face on the pressure reducing port 52d side of a spool 52' through the force of a spring 92. When an atmospheric pressure is low, the bellows 91 is expanded to press the spool 52' in a direction, in which a drain port 52e is opened, through the force of the spring 92. Thereby, a line pressure to a specified boost pressure is set to a value lower than that during running at lowlands, characteristics of the line pressure to the boost pressure are also decreased generally. Thus, even during running at highlands in that an engine output is decreased, during transmission of an automatic transmission gear, a line pressure fed to a hydraulic actuator is adapted for torque or an engine output, being to be transmitted to a clutch or a brake, and a high transmission shock caused due to a fact that a line pressure is excessive is prevented from occurring.

Title: Photoelectric transducer
Inventor: MURAMATSU SHINICHI
IPC: H01L31/042
Filed: 1984-07-27
Abstract: PURPOSE:To enable an electrical output corresponding to each individual pattern of the incident light to be obtained, by connecting photovoltaic elements in such a manner that the electrical output obtained when all the photovoltaic elements are irradiated with light is smaller than the electrical output obtained when the elements are partially irradiated with light. CONSTITUTION:Photovoltaic elements No.1 and No.2 are electrically connected in parallel so that they are opposite in polarity to each other, thereby forming each of the units. The units are connected in series in such a manner that no electromotive force is produced between output terminals 2 when all the photovoltaic elements are irradiated with light. When the number of odd-number photovoltaic elements 1 irradiated with light and the number of even-number photovoltaic elements 1 irradiated with light are equal to each other, no electromotive force is produced between the output terminals 2, whereas, when these numbers are not equal to each other, an electromotive force is produced between the output terminals 2. Thus, the electrical output depends upon which elements in the photovoltaic element group are irradiated with light. It is therefore possible to identify each individual pattern of the incident light from the electrical output.

Title: Optical recording disk
Inventor: AKAHIRA NOBUO
IPC: G11B7/24
Filed: 1985-07-15
Abstract: PURPOSE:To obtain the recording disk which has a little noise, a small volume weight, can be easily manufactured and is inexpensive by forming the transparent layer having the difference of 0.2 or below in the refraction factor and the opaque layer added the pigment on the recording thin film. CONSTITUTION:On a transparent substrate 1, a transparent synthetic resin layer 3 and an opaque synthetic resin layer 4a added the pigment to the material are formed on a recording thin film 2. The incident light from the substrate 1 is absorbed and scattered by the pigment in the layer 4a, the intensity of light to reach an interface 401 with the outside air comes to be little, the refraction factor difference between the layer 3 and the layer 4 is set to 0.2 or below, and thereby, the reflecting is suppressed at an interface 301. Consequently, the noise due to the reflection from an interface between a protective film 4a and an outside air is decreased, and the high quality signal can be recorded and reproduced.

Title: Noise resistance microphone
Inventor: UEDAHIRA YOSHIRO
IPC: H04R1/00
Filed: 1986-07-02
Abstract: PURPOSE:To remove noise and to realize a communication with a clear voice by pressing a vibration sensing type transducer high in an acoustic impedance against a sound receiving block having a suitable curing. CONSTITUTION:The vibration sensing type transducer 1 seals a transducer 4 using a piezoelectric element in a thin metal case 2 through a damping oil and transforms the deformation of the piezoelectric element based on the vibration impressed in a direction shown by an arrow into an electric signal. The transducer 1 is tightly fixed to the hard acrylic block 5 by a bonding agent 6 such as epoxy resin, thereby, if the vibration propagated through the acrylic block 5 is detected, the acoustic impedance of this microphone structure is extremely large in comparison with that of air (about 10<6>times), so that an external influence due to the noise is hardly received. A non-bonded surface to the acrylic block 5 of the transducer 1 may be further effectively covered with a sound absorbing material 7 such as a silicone rubber or a sponge.
