Title: Structure of impedance matching material for ultrasonic sensor
Inventor: HASEBE NOBORU
IPC: G01N29/24
Filed: 1991-04-25
Abstract: PURPOSE:To prevent a receiving level from lowering due to the influence of a standing wave by providing a step difference of 1/4 of wavelength lambda of an ultrasonic element on the surface of an impedance matching material, and setting high/low parts to a prescribed ratio. CONSTITUTION:The influence by a standing wave is generated due to a fact that an ultrasonic wave from a transmitter is reflected from an object and reflected repeatedly between the object and the transmitter. In the case of the transmitter driven by 210kHz resonance frequency, when the speed of sound is 340m/s, wavelength lambda is 1.6mm. Accordingly, whenever a distance between the object and the transmitter moves by lambda/4=0.4mm, a receiving level becomes lower. In order to prevent it, a step difference of thickness of lambda/4 is provided by an area of a prescribed ratio of the surface area on the surface of an impedance matching material. The step difference, can be provided in a shape of a concentric circle, a half-moon, a bamboo blind, etc., and sticking is also allowable. In such a way, even if there is the influence of a standing wave, a receiver can hold a roughly constant level.

Title: Sash window
Inventor: TAKAYANAGI TAIJI
IPC: E06B3/14
Filed: 1994-08-31
Abstract: PURPOSE:To decrease the number of parts by forming each rail and stile of a sash window, in which the inside of an opening-section frame is partitioned vertically and horizontally and a plurality of unit window bodies are mounted, in the same shapes while the width of a mullion and a transom is formed in the depth width or less of a unit window body rail or stile. CONSTITUTION:When a sash window, in which a comparatively large window opening section W is partitioned crosswise and a plurality of unit window bodies 1 are combined, is formed, the rails and stiles 4 of each window body 1 are molded in the same shapes. The rails or stiles 4 are installed to an opening- section frame body 6 through auxiliary tools consisting of arm hooks 8, arms 9, etc. When mullions 7 are used, the rails or stiles 4 are mounted on the mullions 7 through auxiliary tools such as sliders 10, pivot hinges 11, etc., while the width of the mullions 7 is made smaller than depth width formed by both rails or stiles 7 of the unit window bodies 1. A sash window using no transom is formed when a stepped window is constituted besides the usage of transoms in place of the mullions when the window opening section W is partitioned vertically. The number of parts is decreased, and execution is facilitated while the mullions and the transoms are not viewed from the outside.

Title: Optical fiber cable
Inventor: SEKII YUICHI
IPC: G02B6/44
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To lessen the increase of the transmission loss when a cable is bent by laminating plural sheets of ribbon-like coated optical fibers in a direction perpendicular to the plane inclusive of the regulated bending direction of this cable. SOLUTION: The optical fiber calbe 5 is obtd. by forming plural sheets of the ribbon-like coated optical fibers 1 which are laminated and are provided with integral coatings 2 on their outer peripheries as cable cores 3 and coating the outer periphery of such cable cores 3 with a protective sheath 4. The bending direction at the time of winding the cable 5 on a drum is an arrow direction. Namely, the cable 5 is formed by laminating the plural tape-like coated optical fibers 1 in the direction perpendicular to the plane inclusive of the regulated bending direction. If the cable is constituted in such a manner, the waving of the tape-like coated optical fibers 1 does not arise when the cable 5 is bent and, therefore, the increase of the transmission loss is lessened.

Inventor: OGOSHI TAKESHI
IPC: H01L21/30
Filed: 1990-08-06
Abstract: PURPOSE:To exclude dimensional change of the upper part and the lower part of a step-difference, by a method wherein, when the resist spread on a substrate having the step-difference is exposed to light and developed, and a hole pattern is formed on each of the upper part and the lower part of the step-difference, the exposure is performed in the manner in which the focus position with respect to a substrate is changed for the upper part and the lower part of the step- difference. CONSTITUTION:Firstly by using a mask for the upper part 35 of a step- difference on a semiconductor substrate, focus position is set on the upper part 35 of the step-difference, and alignment and exposure are performed by a demagnification aligner stepper. Secondly by using a mask for the lower part 34 of the step-difference, focus position is set on the lower part 34 of the step-difference, and alignment and exposure are performed by the stepper. After that by development, each desired hole pattern is formed on each of the upper part 35 and the lower part 34. Since exposure is enabled by setting each of the optimum focus positions for upper part 35 and the lower part 34, the difference of hole dimension is not generated between the upper part 35 and the love part 34.

Title: Difference signal generating circuit
Inventor: TSUNEKAWA TOKUICHI
IPC: G01C3/06
Filed: 1983-11-04
Abstract: PURPOSE:To enable accurate detection of the difference of 2 signals, by constructing 2 electric charge accumulators per each light receiver in a circulating loop and computing the difference of 2 signals with the electric charge accumular and an operational amplifying means. CONSTITUTION:Photoelectic charges generated in light-sensitive image elements S1-SN are accumulated by an electric charge accumulators ST1. When phiSH1 and phiA reach high level, the electric charge accumulated in the accumulator ST1 is transmitted tentatively to an electric charge transmittor and when it is inverted the phiSH1 low level, then the electric charge is accumulated in an accumulator ST2. When electric charges accumulated in the accumulators ST1, ST2 are transmitted tentatively to electric charge transmittors GA, GB and phiSH1 is inverted to the low level, the information charge of the ambient light is accumulated in the accumulator ST2. The information charge at the light emission time is delivered to the accumulator ST1 and after addition, the same operation is repeated successively. Light information at the light emission time and the same at the light non-emission time are added in a circulating manner. Thus, the difference signal of 2 signals obtained from a photoelectric convertor at the time of light emitting and light non-emitting times can be detected at high accuracy.

Title: Magnetic recording medium
Inventor: SHIGA AKIRA
IPC: G11B5/64
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To improve the corrosion resistance of a magnetic layer by forming a metallic thin film type back coating layer having a higher ionization tendency than the constituent metal of the magnetic layer. SOLUTION: A magnetic layer Mag consisting of Co in a prescribed thickness is formed on one side of a substrate made of a polyethylene terephthalate (PET) film having a prescribed thickness. A back coating layer BC having a prescribed thickness is formed on the other side by vapor-depositing an Fe-Cr alloy (Fe:Cr=20:80). Since the relation among the ionization tendencies of the metals is Cr>Fe>Co, even if the protective layer of the resultant magnetic recording medium is damaged by repeated use, an oxidizing substance reacts with the metals of the back coating layer having higher ionization tendencies to water than the metal of the magnetic layer. As a result, the corrosion of the magnetic layer is prevented and the corrosion resistance of the magnetic layer is improved.
