Title: Torque sensor for automatic transmission
Inventor: TAKATORI KAZUHIRO
IPC: F16H61/10
Filed: 1987-07-13
Abstract: PURPOSE:To make it possible to directly detect a rotational torque transmitted to an input shaft so as to improve control accuracy by forming a circular torque sensing face on the outer circumference of an input shaft and arranging a torque sensor having a sensing coil on stationary portion side cylindrical ember opposite to the torque sensing face. CONSTITUTION:A torque sensing face 20A is formed on the outer circumference of the input shaft 6 of an automatic transmission by having direct shape mag netic anisotropy generated on this outer circumference. The magnetic permeabil ity change of the torque sensing face by tensile force or compressive force based on a torque acting on the torque sensing face 20A is detected by the flat sensing coils 34A, 34B of a torque sensor 20B which is arranged at the cylindrical portion 4a of a cover fixed on a transmission case side opposite to the torque shaped face. Thus, the input torque transmitted to the input shaft 6, i.e., the turbine torque of a torque converter, can be accurately detected directly so that the use of this torque sensing value can remarkably improve the control accuracy of a speed change controller which restrains a speed change shock.

Title: Prevention of violet fall of furniture
Inventor: OGAWA MASAAKI
IPC: A47B97/00
Filed: 1995-06-16
Abstract: PURPOSE: To prevent the generation of the death accident, injury and physical damage accompanied by the violet fall of furniture by reducing the friction resistance of the bottom surface of furniture with a floor surface by increasing the contact area of the bottom surface of the furniture with the floor surface not only to make the furniture easy to slide on the floor surface but also to allow the same only to slide even upon the reception of violet vibration. CONSTITUTION: For example, the width of the earth part formed to the peripheral edge part of the bottom surface 2 of a commercial locker in a protruding state is set to, for example, 45mm and the contact area of the bottom surface 2 with a floor surface is set to 3 times a conventional contact area. Since the contact area of the bottom surface 2 with the floor surface is increased to reduce the load per a unit area of the earth part 3 of the locker, the friction resistance with the floor surface can be reduced and the locker 1 becomes easy to slide on the floor surface and only slides on the floor surface even upon the reception of violent vibration to be prevented from falling down violently.

Title: Semiconductor device
Inventor: UCHIDA YOKO
IPC: H01L21/338
Filed: 1988-07-15
Abstract: PURPOSE:To obtain favorable breakdown strength by using a semiconductor having a high resistance because it has a lattice constant mismatching with that of a semiconductor, instead of an insulating film. CONSTITUTION:On a semi-insulating GaAs substrate 1, an undoped GaAs layer 2, an n-type GaAs layer 3 and an undoped InGaAs layer 4 are formed in order. The undoped InGaAs layer 4 serving as an insulating layer, the thickness can be varied depending on the content of In vs. Ga. Expressing the undoped InGaAs layer 4 as InxGa1-xAs, the InGaAs layer can be a high resistance layer when it has the thickness of 10nm or more with the content x of In of more than 0.4. As a semiconductor film in place of an insulating layer, such a semiconductor as forms a high resistance layer because it has a lattice constant mismatching with that of a semiconductor formed directly under it is used. It is possible to manufacture an MIS-structure-like semiconductor device easily without any restrictions on material by taking advantage of a high resistance layer formed using a mismatching of a lattice constant.

Title: Connecting board for color liquid crystal display
Inventor: KASUGA KOJI
IPC: H05K1/02
Filed: 1994-07-27
Abstract: PURPOSE:To suppress the deformation due to thermal expansion by the ambient temperature change for decreasing the shearing force on TCP by a method wherein power supply patterns and grounding patterns are formed in mesh form making a specific angle with the length direction of the board contour. CONSTITUTION:Within a meshy pattern 4a, square pattern holes 5 having one side of 0.5mm making an angle of 45 deg. with the axial line X-X in the length direction of the contour of a connecting board 3 are provided, each of the same pattern holes 5 are arranged at 0.7mm pitch in the longitudinal and lateral directions to be formed in mesh form.

Accordingly, the reliability upon the thermal shock of a color liquid crystal displayer can be improved.

Title: Manufacture of semiconductor device
Inventor: YAMAZAKI SHUNPEI
IPC: H01L21/205
Filed: 1985-08-08
Abstract: PURPOSE:To assure the high reliability by a method wherein a semiconductor containing hydrogen or halogen element is formed on a substrate and then fluorine is doped to the surface or inside of the semiconductor without bringing the semiconductor into contact with atmosphere. CONSTITUTION:A semiconductor material containing hydrogen or halogen element is formed and then fluorine is doped to the surface or inside of semiconductor in no-oxygen atmosphere. Thus Stabler Wronskian effect showing metastable state peculiar to an amorphous semiconductor can be prevented from happening since the hydrogen on the surface apparently existing on the inner surface of semiconductor due to void etc. can be substituted with fluorine for stabilization by doping fluorine without bringing the semiconductor into contact with atmosphere. Besides, the coupling of Si-H, Si-O can be substituted with the coupling of Si-F for stabilization to prevent any residual stress, void as well as any damage to P-I, N-I and P-N junctions from happening.

Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To securely prevent filming, which is caused by fine powder such as toner and paper powder sticking to the surface of an image carrier, with no cost increase in the image forming device as a copying machine. SOLUTION: In a position which is upstream from a cleaner 16 in the direction of the rotation of the photoreceptor 10, a P-sensor is provided for detecting soil on the base of the surface of it.

Abstract: PURPOSE:To instantaneously respond to a receiving state affected by momentarily changing weather, by sampling a receiving signal during an antenna stationary period while automatically adjusting an integration time. CONSTITUTION:A radio wave from a satellite is inputted to a voltage/frequency converter (V/F)3 through an antenna 8, a receiving apparatus 1 and a low band pass filter 2 and converted to frequency and the output of the converter (V/F)3 is subjected to the counting of the number of cycles by a frequency counter 4.
