Title: Calcium phosphate cement composition for oranism
Inventor: SATO TSUGIO
IPC: A61K6/838
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To make biocompatible, strong, less irregular in strength and manipulatable at the time of grinding by containing calcium titanate fibers as a base material in a calcium phosphate cement composition for organisms. SOLUTION: The calcium phosphate cement composition for organisms is formed of a base material whose main component is calcium phosphate and a miscible solvent. And furthermore calcium titanate fibers are mixed as a base material. Calcium phosphate used as a main component of the base material is not limited as long as it reacts at the presence of water or a pseudo liquid, and produces and hardens hydroxyapatite. The calcium titanate fibers are preferably fine fibers 0.1 to 100 μm in average length, 0.01 to 10 μm in average diameter, and 3 to 50 in aspect ratio. The miscible solvent is one to grind a base material and generally water or ion-exchanged water.

IPC: F17C13/06
Filed: 1985-04-12
Abstract: PURPOSE:To prevent a lid from being blown off in an erroneous operation of the lid, by providing stepped primary and secondary stoppers for holding the lid within a range of a predetermined rotative angle of the lid at axially inside and outside portions. CONSTITUTION:An engagement portion 12 is formed with three engagement projections 51 extending circumferentially at equal pitch.

IPC: G01B11/24
Filed: 1991-04-10
Abstract: PURPOSE:To enable an object to be inspected by a simple method by measuring a measurement part by matching a target picture image to the corresponding figure. CONSTITUTION:For example, when inspecting an inside of a jet engine, an image of a blade 6 is picked up by inserting an electronic endoscope 2 through an inspection hole of an engine, for example, when inspecting an inside of a jet engine.

IPC: H04L25/02
Filed: 1984-04-20
Abstract: PURPOSE:To make the titled circuit suitable for high frequency operation and to reduce the effect of a switching noise on other circuit by using a resistor mounted externally to an IC to adjust a collector current of a transistor (TR) in switching operation to a collector of which a load resistor is connected into an optimum value. CONSTITUTION:In order to adjust a level of an FM demodulation signal output 9, an IC pin 30 and a variable resistor 37 are mounted at the outside of the IC. A TR34 is operated accoding to the base voltage and when the TR34 is turned off, a TR33 is turned off and a voltage of an input/output pin 31 of the IC is equal to a power supply voltage Vcc. When the TR34 is turned on, a collector current iL flows, since the collector current iL flows, the collector current iL of the TR33 is nearly equal to the iL, the voltage of the pin 31 is Vcc-iL R38. Then the FM demodulation signal level is adjusted by adjusting the resistor 37. Then the resistor 38 is set to a degree that the deterioration in the frequency characteristic due to the parasitic capacitance of the pin 31 is not a problem and the FM demodulation signal level is varied by the current value iL, then high frequency operation is attained. Moreover, since the current value iL is adjusted to a required minimum value, ripple noise is suppressed.

Title: A/d conversion system
Inventor: IIDA KAZUMASA
IPC: H03M1/20
Filed: 1989-03-31
Abstract: PURPOSE:To simply improve the resolution by adding a dither signal whose level varies so that its mean level is zero to an input signal, applying A/D conversion to the result, and averaging the obtained digital signal. CONSTITUTION:An input signal ein is subject to A/D conversion while a change in a dither signal Sd is superimposed thereupon. Then a digital signal ein-2 obtained as a result represents a value on the way of an area between a threshold level Tho with the input signal belonging thereto and a succeeding threshold level Th1. Thus, the resolution is improved. On the other hand, since the dither signal Sd is zero because of averaging, the effect superimposed with the dither signal Sd is eliminated from the digital signal ein-2.
