Title: Method for measuring thickness in laminated structure
Inventor: HONDA SHUNJI
IPC: G01B15/02
Filed: 1989-09-29
Abstract: PURPOSE:To highly accurately measure thickness of each layer by a method wherein a pulse wave is radiated to a laminated structure, a synthesized reflection wave is decomposed and extracted as reflection waves of a surface and respective layers, their time differences are detected, and the difference and the dielectric constant of each layer are used to calculate the thickness. CONSTITUTION:A pulse wave is radiated to a pavement where a surface At, a sub grade St and a road bed Mt are laminated, and a synthesized reflection wave of waveforms reflected on the surface and borders of the respective layers is received. Reflection waveforms W11 to W13 of the surface and the respective layers are decomposed and extracted from the synthesized deflection wave. With a time axis of the waveforms W11 as a reference, respective time differences D1 to D3 of the reflection waveforms W11 to W13 are calculated. An equation I is used to calculate thickness L of a layer based on the time difference D and a dielectric constant epsilon of each layer which is obtained as data in advance. Thus thickness of a layer can be measured at high accuracy quickly and continuously.

Filed: 1993-09-17
Abstract: PURPOSE:To improve operability by performing necessary down-shift operation speedily at the time of changing into a manual speed change mode. CONSTITUTION:When selection of a second range position D2 in which a speed change stage in which engine brake is in an effective condition can only be set by a shift device 40 is detected by a shift detection means 41, a speed change instruction means 43 instructs change into a speed change stage in which the engine brake is effective to the low speed side by a specified stage number from a speed change stage detected by a transmission stage detection means 42 immediately before that. When a mode is changed into one in which the speed change stage can be set by manual operation, down-shift occurs in accordance with the operation. Engine brake force can thus be increased, or acceleration ability can be increased, with operability for the purpose improved.

Title: Field winding for superconducting generator
Inventor: YAMAGUCHI KIYOSHI
IPC: H02K55/04
Filed: 1990-09-28
Abstract: PURPOSE:To obtain a field winding for a superconducting generator in which a field winding is rigidly supported fixedly to a tee for forming a slot by forming a lower insulating spacer arranged in the bottom of the slot of nonmagnetic metal coated with an insulator and having high resistance, high density and high strength. CONSTITUTION:In the case of 3600rpm of rated rotating speed as an example of a 1000MW class dipole superconducting generator having a lower insulating spacer 7 made of semicircular stainless steel of 40mm of diameter of sectional size in the bottom of a slot 2, the spacer 7 affects a pressure of 4.46MPa to a field winding 4. Heretofore, since it is formed of glass fiber reinforced plastic(FRP) in a rectangular shape, twelve times of pressure is obtained due to a difference of densities and shapes of the stainless steel and the FRP. Accordingly, a coil is rigidly supported to a wedge 5. No hysteresis loss is generated due to the nonmagnetic metal, and an induced current generated therein can be suppressed to a small value due to the high resistance.

Title: Photo-secondary cell
Inventor: KANBARA TERUHISA
IPC: H01M10/054
Filed: 1985-11-15
Abstract: PURPOSE:To obtain a larger discharge current by employing a material mainly composed of NbxZrSy (0<x<1, 1.8<=y<=2.1) or a compound of NbS2 and ZrS2 as a positive electrode material. CONSTITUTION:A negative electrode mainly composed of metal copper, a Cu<+> ion conductive solid state electrolyte and a positive electrode mainly composed of sulfide of Nb and Zr are laminated sequentially, and the obtained cell can be recharged by irradiating the light onto the positive electrode. Main cause of polarization of cell is the activating energy for moving the charges on a contacting face between an electrolyte and a positive electrode material. The lower the activating energy, the quicker the electrons are passed and received, thereby the polarization as a cell becomes lower. When ZrS2 is doped with Nb, the activating energy will lower so as to reduce the polarization.

Abstract: PROBLEM TO BE SOLVED: To provide a golf club having a sweet spot of expanded elliptical form on the center of a face, and a head designed to transmit maximum energy to the center of a ball. SOLUTION: The actual center of gravity G of a head 1 is set so as to come on the intersection of lines passing through the center of gravity positioned at the center of the upper surface of a head 1, a face 4 and a toe 5, and a distance (a) from the intersection of a line drawn from the actual center of gravity G to the sweet spot of the face 4 with a shaft axial line up to the actual center of gravity G is made equal or approximately equal to a distance (b) from the intersection to the face 4.
