Abstract: PURPOSE:To make the thickness of a photo detecting layer small for increasing an efficiency by constituting the photo detecting layer with a super lattice which is made in a first direction parallel with the surface of a substrate and in which a conductivity is inverted in a second direction which crosses at right angles with the first direction and is parallel with the direction perpendicular to the substrate surface. CONSTITUTION:When a substrate 41 is a p-type GaAs substrate, a photo detecting layer 43 is constituted of a super lattice. The super lattice which constitutes the photo detecting layer 43 is such that, for example, GaAs layers 43a and AlGaAs layers 43b are alternately located in the direction parallel with a principal plane of the substrate 41 and each of the layers 43a and 43b is a p-type part 43ap or 43bp on the substrate 41 side and is inverted into an n-type part 43an or 43bn midway in the direction perpendicular to the principal plane of the substrate. A super lattice can be formed in the direction parallel with a principal plane of a substrate by such a technology that a GaAs substrate with a (100) surface and a [011] flat is used and a GaAs layer is developed for the first half of the distance from one step to the next step of a crystal formed on the surface of the substrate and an AlGaAs layer is developed for the latter half of the distance. Consequently, a thin photo detecting layer which has a high efficiency is expected to be realized.

IPC: C09D5/08
Filed: 1987-10-20
Abstract: PURPOSE:To obtain the title film which can prevent cracking due to blistering and expansion of the coating film caused by the diffusion of water vapor and therefore can prevent corrosion even through prolonged use, by using a base material and a specified mixture formed on its surface which comes in contact with water vapor or a water-containing substance of a temperature higher than that of the wall of the base material. CONSTITUTION:A corrosion-preventive film which prevents the diffusion of water vapor, consists of a metallic and/or nonmetallic base material and a mixture of a polymetallocarbosilane [e. g., a copolymer of a polycarbosilane having structural units of formulas I and II (wherein R1-R4 are each H, 1-4C alkyl or phenyl) with a compound having units of formulas III and IV (wherein M is Ti or Zr; R5 and R6 are each 1-4C alkyl or O)] with a ceramic powder (e. g., an SiC powder), formed on that surface of said base material which comes in contact with 1 water vapor and/or a water-containing substance of a temperature higher that that of the wall of the base material. Because of excellent resistance to diffusion of water vapor, this film as applied to a metallic and/or nonmetallic base plate of a temperature different by 5 deg.C or greater and/or in, e.g., a region wherein the temperature difference between day and night is great, can prevent the coating film from expanding and blistering due to the diffusion of water vapor so that it can produce an effect of preventing corrosion even through prolonged use.

Title: Reproducing device
Inventor: TAKAHASHI TOSHIHIKO
IPC: G11B15/467
Filed: 1985-11-22
Abstract: PURPOSE:To make specific information such as program searching information readable by controlling the number of rotation of a drum and a tape speed so that at the time of fast tape forwarding the relative speed between a tape and a head can be constant and larger than that at the time of normal reproduction. CONSTITUTION:A reel servo circuit 26 travels the tape 15 at a constant speed of m.N.Vt in a (m.N)-fold fast forwarding mode under the control of a microcomputer 30. A drum servo circuit 29 rotates and controls rotating heads 11A and 11B at a constant speed of m.VD'. Here the Vt and VD' show a tape speed at the time of normal reproduction and N-fold drum (head) speed at the time of fast forwarding, respectively. As a result, the absolute value of the magnitude (thetaT-thetaR) of an angle made thetaT at the time of (m.N)-fold speed can be below some critical value, whereby a relative speed of m.VR' higher by m-times than a relative speed VR' at the time of N-fold speed (namely, a relative speed VRO at the time of normal reproduction) can be obtained. Thus program searching information can be read out at the time of feeding a tape at a high speed.

Abstract: PURPOSE:To enable a member measuring such a size that it has never conventionally entered to enter an opening part of a tape cassette having a limited space by constituting the subject device to be capable of releasing always a brake in the tape cassette during the time when the tape cassette is loaded into a tape driving means. CONSTITUTION:Immediately after starting loading the tape cassette 1, a projecting part 4a of a brake releasing rod 4 is entered into the tape cassette 1 to come into contact with the brake for a tape reel, commencing to release the brake. When the loading of the tape cassette 1 is further progressed, the projecting part 4a is completely entered into the tape cassette 1 so that the brake for the tape reel is released, and afterward a tape drawing plate 6 is started with its slanting part 6a to come into contact with the tape 2. By this method, even in case of a large diameter guide roller 11, this can be entered into a position as shown by a dashed line in the right opening part 8.

Title: Dynamo-electric machine
Inventor: HINO YOUJI
IPC: H02K3/02
Filed: 1989-10-09
Abstract: PURPOSE:To enlarge the permeance factor of a magnetic circuit and to increase effective magnetic fluxes so as to increase torque by forming a magnetic field coil using a conductive line material which has a magnetic core within. CONSTITUTION:A field coil 20 is made by using a conductive line material 20b which has a magnetic core 20a within. The magnetic fluxes of air gaps 22 and 24 pass inside the magnetic cores 20a small in resistance. Supposing that the diameters of the magnetic cores 20a are fixed, the substantial gap length of the air gap 22 and the substantial gap length of the air gap 24 decrease. When the magnetic fluxes inside the air gaps 22 and 24 pass the magnetic cores 20a of the field coils, the magnetic flux links such that it crosses the line material 20b of the field coil 20 at right angles, so the quantity of effective magnetic fluxes can be elevated. Hereby, the generated magnetic flux can be made to cross the field coil at right angles effectively so as to elevate the quantity of effective magnetic fluxes, whereby a small and highly efficient dynamo-electric machine can be obtained.
