Title: Recording method and device
Inventor: IKEDA IKUMASA
IPC: H04N9/79
Filed: 1992-05-01
Abstract: PURPOSE:To eliminate a density unevenness caused by a variation in characteristics of printing elements by a method wherein recording is made on a recording medium based on conversion information read from a storage means in accordance with inputted image data and positional information of printing elements used for printing said image data. CONSTITUTION:On a printed matter obtained by using a thermal head, a recording density of each recording dot is measured correspondingly to each heating resistor. Based on the densities and the positions of corresponding heating resistors, the heating resistors are divided into 8 groups in a ROM 21 so that the heating resistors of the same group approximate in density value. Positional information 24 of the heating resistors is inputted to addresses of the ROM 21. The group is outputted as 3-bit information. A group having a maximum recording density value which is lower than any other recording density value in all the groups is referred to as a group 0. A group having a second lowest recording density value is referred to as a group 1, and the same rule applies to the other groups. Image data 23 for the group 1 is converted. The value of the data 23 is converted so that the recording density of the group 1 can be the same as that of the group 0 for the data 23, and the same conversion method applies to the other groups 2-7.

Title: Circuit apparatus for application connected to inductive and capacitive device for non-destructive measurement of orm resistance of thin film
Inventor: GERUNOOTO TORUN
IPC: G01R27/02
Filed: 1989-05-01
Abstract: PURPOSE: To measure the surface resistance of low and high impedances without contact by detecting the currents flowing at both inductive and capacitive units with inductance for forming an oscillator part for maintaining a resonance state. CONSTITUTION: Both an inductive sensor 2 and a capacitive sensor 3 constitute the parts of oscillators 15 supplied with electric energies from a current supply source 6. The sensor 2 is always connected to a phase regulator 17, and the sensor 3 ma be connected to the regulator 17 though not necessary. The role of the regulator 17 is mainly to tune the frequency of the oscillator 15, and to this end, oscillators 4, 5, 6 are always in resonance state. When this state is satisfied, the total resistance of the oscillators 4, 5, 6 has only ohmic resistance. Accordingly, the current additionally flowing the oscillators 4, 5, 6 becomes a scale of the surface resistance during the measurement of the layer. The currents flowing to the oscillators 4, 5, 6 are amplified by an amplifier 8, and sent to a voltage-current converter 19.  The gain of the amplifier 8 is adjustable by a regulator 20, and the sensors 2, 3 can be calibrated by a calibrating unit 21.

Title: Wind and water powered pump-driving device
Inventor: HANIBUCHI HIROYA
IPC: F04B17/00
Filed: 1981-07-17
Abstract: PURPOSE:To make use of a wide range of wind and water power from low speed to high speed by providing a control valve to control the delivery amount of a pump for reducing the driving power of the pump as maintaining the delivery pressure of the pump at a constant level at the time of low velocities of the wind and water. CONSTITUTION:When wind velocity is almost near to zero, the energy to drive a wind mill 1 and an oil pump 3 cannot be obtained from the wind power, and  the oil pump 3 cannot be driven. However, since the oil pump 3 is of variable  capacity and the delivery amount is controlled almost at zero by a control  valve 10 when the delivery pressure of the oil pump 3 is under a set value, the  driving power of the pump 3 is very small. Therefore, when the wind velocity  comes into a lowwind-velocity area a little higher than zero, the wind mill 1  and the oil pump 3 are started to drive, and pressure oil is sent and discharged  by pressure to a discharge pipe passage 5.
