Patent JP-H02168445-A (JP)
Title: Optical recording medium and its utilizing method
Inventor: UEDA YUTAKA
IPC: G11B7/24035
Filed: 1988-12-22
Abstract: PURPOSE:To obtain a writable medium able to be reproduced by a compact disk player on market by forming an Ag thin film layer and a changing layer made of a material absorbing a light with a wavelength of a specific range and causing state change on a base. CONSTITUTION:A nitrocellulose background layer 2 is provided on a base 1 and an Ag thin film 3 whose thickness is 50 - 2,000Angstrom is vapor-deposited on the layer 2. Moreover, a resin layer 4 in which carbon black is dispersed is provided on the film 3. The Ag has a minimum reflectivity near a wavelength of 320nm and becomes translucent. When the light in this wavelength range irradiates from the side of the Ag thin film 3, the light transmits through the layer 4. Thus, the state of the layer 4 is changed to cause the state change such as deformation to the thin film 3 thereby recording the information. Thus, in the case of reproduction, when a light with a wavelength longer than 320nm is used, a reflectivity of 90% or over is obtained, and since the reflectivity of the recorded part only is low, the medium is reproduced by using a conventional compact disk player.

Inventor: TAMURA KUNIYASU
IPC: A61B8/00
Filed: 1988-12-22
Abstract: PURPOSE:To suppress the generation of heat from a buffer, to prevent the saturation of the buffer, and to improve the quality of an ultrasonic image by changing a current to flow in the buffer correspondingly to the depth from the body surface of a reagent with which an ultrasonic probe comes into contact with each diagnosing part of the reagent. CONSTITUTION:An oscillator 1 is driven through a buffer 2 by a pulser 4, an ultrasonic wave is transmitted to the reagent, further, the ultrasonic wave is received by each diagnosing part of the reagent with the same oscillator, and this input signal is inputted to the buffer. Thereupon, a reference signal S1 is inputted from a reference signal generating circuit 3 to a bias controller 5, the current of the buffer is controlled, the signal from the buffer is amplified in a preamplifier 6, and diagnostic information is displayed on a B mode image display part 7. Thus, an average current can be suppressed by increasing the bias current of the buffer at a shallow diagnosing part and decreasing the bias current of the buffer at a deep diagnosing part. Consequently, the generation of the heat from the buffer can be suppressed, the saturation of the buffer can be prevented, and the quality of the ultrasonic image can be improved.

IPC: B24D3/06
Filed: 1990-11-26
Abstract: PURPOSE:To stabilize tooth profile and manufacture products of fixed quality by making an internal tooth honing stick itself out of metal, and electrodepositing abrasive grains made of CBN on the tooth surface. CONSTITUTION:At first an external tooth honing stick 3 is formed, by electro- depositing abrasive grains 2 made of CBN in a single layer on the tooth surface of a master gear of external tooth. Next, a gear 4 of internal tooth to be honed is machined with the external tooth honing 3 to form an internal tooth gear 5, and similarly abrasive grains 2 made of CBN are electrodeposited in a single layer on the tooth surface of the internal tooth gear 5 to form an internal tooth honing stick A. Hereby, because the internal tooth gear is accurately machined, the internal tooth honing stick which is manufactured by uniformly electrodepositing grains made of CBN on the tooth surface of it, can be accurately formed. Consequently, honing accuracy with the internal tooth honing stick can be remarkably improved.

Title: Movement adaptive scanning line inteprolation circuit
Inventor: SAGAWA KENTA
IPC: H04N7/01
Filed: 1989-12-14
Abstract: PURPOSE:To eliminate line flicker disturbance generated in an incomplete telop character or the like by detecting and eliminating a false movement detection signal caused by the incomplete telop character or the like from a movement detection signal. CONSTITUTION:An output of an absolute value circuit 94 is fed to a timing adjustment delay device 97 and also fed to a comparator 101 and the comparator 101 compares an absolute value of a one frame difference signal with a threshold level and when the absolute value is larger than the threshold level, a logical H is outputted and when the absolute value is smaller than the threshold level, a logical L is outputted. Moreover, an output logical value of a three-input NAND gate 104 goes to logical H only when an input logical value is A=L, B=H, C=L pattern. Since most of false one-frame difference signal caused by a defective telop character corresponds to this pattern, only when a false movement takes place, the output logical value of an AND gate 104 is H and a coefficient converter 105 converts a coefficient 1-k and a coefficient (k) from a coefficient generator 105 into other values according to a false movement detection signal.

Title: Method for detecting blocking of air-filter
Inventor: ISHIWATARI MASAOKI
IPC: G01N25/72
Filed: 1988-12-26
Abstract: PURPOSE:To precisely detect blocking of an air-filter in a narrow place by providing temperature sensors on the upstream side and downstream side of the air-filter for dust protection to monitor differences in detected values by means of both temperature sensors. CONSTITUTION:A first temperature sensor 21 is provided upstream of an air- filter 10 for dust protection installed in an air intake A, while a second temperature sensor 22 is provided downstream thereof, and heating elements R are provided just upstream of the sensor 22. Temperatures detected at the sensor 21 remain unchanged regardless of blocking of the filter 10, where outdoor temperatures are detected, whereas the sensor 22 detects the temperature of air having been heated to a higher temperature by means of the heating elements R as long as the filter 10 is not blocking, whereby differences in detected values of both the sensors 21, 22 are great. On the other hand, the filter 10 has got blocked, the quantity of air passing the heating elements R decreases, whereby the sensor 22 is not influenced so much by the rise in temperature due to the elements R, so that differences in detected values of the sensors 21, 22 are small. Depending on the magnitude of differences in detected values, blocking of the filter 10 can be found out.

Abstract: PURPOSE:To prevent reflection in an optional two-wavelength range by forming a 1st substrate refractive index adjusting layer and a 1st reflection preventing layer to wavelength lambda1 and interposing an unparticipant layer to the wavelength lambda1 at least one place. CONSTITUTION:When the refractive index of a substrate S is denoted as nsub, a two-layered reflection preventing film (V coat) needs to consist basically of the substrate refractive index adjusting layer with optical film thicknesses n1d1=lambda1/4 and n1=(nsub)<1/2>.n2 and the reflection preventing layer made of a material n2 with a low refractive index n2d2=lambda1/4 so as to preclude reflection of the wavelength lambda1 efficiently. When reflection is precluded in the two- wavelength range of lambda1 and lambda2, a lambda2 substrate refractive index adjusting layer and a lambda2 reflection preventing layer are only provided so as to preclude reflection of lambda2 without spoiling characteristics of the V coat to the lambda1. The unparticipant layer is constituted to an integral multiple of n1(lambda1/2) or/and n1(lambda1/4)-n2(lambda1/2)-n1(lambda1/4), and the refractive index of the unparticipant layer is selected corresponding to the substrate refractive index adjusting layer and reflection preventing layer.
