Title: Agent for disintegrating brittle material
Inventor: INOKUCHI YUKIO
IPC: C09K3/00
Filed: 1982-02-19
Abstract: PURPOSE:To provide the titled disintegrating agent capable of exhibiting expansion force in a short time without erupting from the free surface only by kneading with water and filling in a hole bored to the material to be disintegrated, and disintegrating the mateiral in a shorter time, by crushing clinker composed of free lime powder coated with copper oxide. CONSTITUTION:The raw material obtained by mixing (A) 100pts.wt. of 90.0- 99.9wt% (after calcination) of free lime crystal particles and 0.1-10.0wt% copper oxide or their mixture with (B) <=10.0pts.wt. of solid solution of calcium ferrite and (C) <=30pts.wt. of gypsum, is calcined at 1,000-1,600 deg.C to coat the surface of the free lime cyrstal particle with molten copper oxide, etc. The obtained clinker is cooled and crushed to a fineness of 500-5,000cm<3>/g (Blaine value). The crushing is carried out if necessary in the presence of a cement additive (e.g. lignin-based additive) to obtain the objective disintegration agent. The agent is used by adding 25-45pts.wt. of water to 100pts.wt. of the agent, kneading the mixture, and filling in the hole bored to the material to be disintegrated.

Title: Comparator circuit
Inventor: NAKAYASHIKI YASUO
IPC: H03K5/08
Filed: 1988-02-03
Abstract: PURPOSE:To set a bias voltage with a desired accuracy by a digital data and to attain the quick setting by inputting a digital signal with a prescribed bit to a control terminal and outputting a voltage in response to its digital data. CONSTITUTION:A reference signal is inputted to a noninverting input of a comparator circuit 1 to be tested via a voltage division circuit comprising resistors R3, R4. On the other hand, the reference voltage Vref is given to a voltage output DA converter 2 of a voltage output type with a 6-bit control input. The output of the converter 2 is 0V when all the digital input bits are 0 and the output of the converter 2 is Vref (63/64) when all the digital input bits are at level 1. That is, the voltage Vref is divided by a ratio of the display value of the digital control input to the maximum display number and the result is impressed to an inverting input of the circuit 1. Thus, the potential at a point P is set optionally. That is, the bias voltage is set optionally by a digital control input. The setting voltage is given more accurately by increasing the bit number of digital input.

The output signal is inputted to signal processing part 4 via preamplifier 2 and A-D converter 3. Signal processing part 4 has a reciprocal generating circuit which generates an output signal proportional to the reciprocal of an input digital signal, and a multiplying circuit; the photoelectric conversion part output generated by using a reference light source is inputted to the reciprocal generating circuit and then the obtained output of the reciprocal generating circuit is multiplied by a signal based upon an object to be measured, thereby correcting the characteristic deviation of the individual infrared- ray detector. The corrected output is inputted to display part 10 via D-A converter 5 and display controlling circuit 6.

Filed: 1978-03-03
Abstract: PURPOSE: To automate the winding operation of a signal from the first to the end without increasing the value of acceleration instruction higher than predetermined value when actual speed is accelerated to reach predetermined value smalled by the value of a deceleration instruction.
