Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a clock generating circuit that can generate a clock signal synchronously with an input signal independently of the frequency of the input signal without increasing a circuit scale. SOLUTION: An input selection circuit 1 makes a selection as to whcih of input clocks CK1, CK2, CK3 received from an external device is to be given to an input frequency counter circuit 5 and a 1/N counter 2 on the basis of a selection signal G. The 1/N counter 2 frequency-divides the received clock CK on the basis of a frequency division ratio set to its inside and outputs the result of frequency division to a PLL oscillator 3 as a frequency division clock CKn. The PLL oscillator 3 is a conventional PLL oscillator consisting of a phase comparator, a low pass filter and a voltage controlled oscillator. The frequency divider 4 applies frequency division to a received original oscillation clock Cko at a prescribed frequency division ratio set in its inside and outputs a timing signal CKB and a system clock CKs.  The system clock CKs is used for a unit to which this clock generating circuit is provided.

Title: Flat plate microlens array with reflection surface and its production
Inventor: KUSUDA YUKIHISA
IPC: G02B6/32
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to change an optical path length without affecting optical characteristics by forming a surface formed with lenses as a substrate front surface and the surface on the side opposite thereto as a substrate rear surface and reflecting the incident light from the substrate front surface along the optical axis in a direction exclusive of the optical axis direction by the substrate rear surface. SOLUTION: The surface of this flat plate microlens 104 on which the microlenses 101 are formed within a transparent substrate, for example, a glass substrate 100, is formed as the substrate front surface 500 and the surface on the side opposite thereto is formed as the substrate rear surface 501. In such a case, the substrate rear surface 501 is sloped at an inclination of θ with the optical axis of the microlenses 101. The substrate rear surface 501 has a structure to reflect the incident light from the substrate front surface 500 along the optical axis toward the front surface 502 exclusive of the direction of the optical axis.  The angle 6 that the refractive indices 501 forms with the optical axis of the microlenses 101 is so selected as to attain the angle satisfying the condition θ=cos<-1> (1/n) under which the incident light is totally reflected when the circumference of the flat plate microlens is formed of the atm. air and the refractive index of the glass substrate is defined as a real number (n) larger than 1.

Title: Casting method of super-cooling metal
Inventor: SHIODA SHIGEO
IPC: B22C9/22
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To faithfully replicate a minute shape and to prevent the defects such as shrinkage cavity, crack, misrun, by melting an alloy material, heating to a specified temp., pouring molten alloy material immediately into a cooled mold and rapidly cooling it. SOLUTION: The alloy material is heated to the temperature higher than the m.p. of the alloy +200 deg.C after melting. Desirably, the temp. of the cooled mold is not higher than the crystallizing temp. of the casting alloy. Since the super-cooling metal is not subjected to a phase transformation in the molten state at the solidifying time, the gas is not generated and the molten metal can be heated to high temp. In the casting of the super-cooling metal, since the molten metal is beforehand melted at the high temp., the molten metal is run over the minute shape and not solidified during casting into this mold. When the molten metal is run over the all corners, the molten metal is vitrificated by being rapidly cooled with the mold to produce the super-cooling metal.  As an ornament and a dental material produced with a precision casting, the super-cooling metal of Pd-Cu-Ni-P or Zr-Al-Ni-Cu-Pd is used.

The leakage of the radio wave to be suppressed can be thereby made minimum.

Title: Artificial dental root

IPC: A61C8/00
Filed: 1990-04-11
Abstract: PURPOSE:To enhance strength as a whole by forming a ceramic material into a cylindrical shape opened at both ends thereof not only to make the molding and processing thereof easy but also to make the formed cylindrical body hard to crack and inserting a bottomed cylindrical metal substrate having a flange at one end thereof in the cylindrical body. CONSTITUTION:An apatite cylinder 11 is formed into a cylindrical shape having the same diameter and both end parts thereof are opened. A bottomed cylindrical metal substrate 21 composed of titanium has the bottomed cylindrical part 21a inserted in the apatite cylinder 11 and the external flange part 21b formed to the end part of the bottomed cylindrical part 21a on the side opposite to the bottom part thereof. Since a ceramic material having relatively fragile properties is formed into the simple cylindrical shape opened at both ends thereof, no stress concn. is generated at the times of sintering and processing and the possibility of the generation of a crack caused by stress concn. is eliminated. The outer surface of the bottom part exposed from the lower end surface of the cylindrical ceramic material of the bottomed cylindrical metal substrate 21 comes into contact with a jawbone but, when a proper material, for example, titanium is selected as the metal substrate, the problem from the aspect to bio-compatibility is not generated.

Abstract: PURPOSE:To obtain a processing rack with which the advancing position and the advancing angle of a photosensitive material to a guide plate are adjusted to appropriate ones and the photosensitive material is surely guided and carried without causing a fault in passage. CONSTITUTION:An intermediate block 189 is interposed between a side plate 142 and a guide plate 187, and a screw 191 is screwed in a female screw 187D. When the screw is loosened, the intermediate block 189 and the guide plate 187 can be rotated centering around a pin 187C, so that the advancing angle of the photosensitive material 14 to the guide surface 187A of the guide plate 187 is changed. Meanwhile, a long hole 142B is formed on the side plate corresponding to a pin 189C and a female screw 189D on the intermediate block 189. When a screw 193 is loosened, the intermediate block 189 is moved in the horizontal direction with respect to the side plate 142, that is, in the longitudinal direction of the long hole 142B, thereby changing the advancing position of the photosensitive material 14 to the guide surface 187A of the guide plate 187.

Title: Background eliminating device
Inventor: ITO AKIHIRO
IPC: H04N1/40
Filed: 1993-04-22
Abstract: PURPOSE:To eliminate background at high speed without necessitating preliminary scanning by sampling a picture element for each line of a digital picture signal and using its mean value as a background density and using a threshold level obtained by adding a predetermined offset to the background density, thereby eliminating the background for each line. CONSTITUTION:A picture element sampling means 1 samples a picture element for a predetermined interval from a picture signal by one line. An average calculation means 2 obtains a mean value of picture elements by one line sampled. An offset adder means 3 adds a predetermined offset to the obtained mean value to decide a threshold level. Then a background eliminating means 4 sets all signals smaller than the threshold level to '0' in an inputted picture signal to provide an output thereby eliminating the background. Thus, the background is eliminated while revising the threshold level for each line to unnecessitate preliminary scanning.
