Title: Spindle control command system
Inventor: SASAKI TAKAO
IPC: G05B19/18
Filed: 1989-02-22
Abstract: PURPOSE:To simplify the switching command between the synchronous control and the single control by switching the synchronous control or the single control of plural spindles based on a program command. CONSTITUTION:The spindle control commands are switched by the commands G08.1 and G08.0 recorded on an NC tape. In other words, the spindles A1 and B3 undergo the synchronous control with the command G08.1 and then the single control with the command G08.0 respectively. The number of resolution of both spindles A1 and B3 are also decided individually in the single control mode. Thus the NC program commands the synchronous control or the single control of plural spindles. Based on this command, a numerical controller CNC switches both spindles between the synchronous control and the single control. Thus the control switching command is simplified.

Title: Delivery drive method in ink jet recording head
Inventor: TAMURA YASUYUKI
IPC: B41J2/14
Filed: 1990-02-26
Abstract: PURPOSE:To increase the density of nozzles to obtain a high-accuracy image by a method wherein when an image signal instructing a delivery is received, voltages of different levels are applied between wiring electrodes at both sides of an electrothermal transducer, and voltages of the same level are applied between wiring electrodes at the both sides of an electrothermal transducer corresponding to a non-delivery nozzle. CONSTITUTION:If a load signal is inputted to a shift register 6 with a clock signal at a time t1, the outputs Q1-QN of the shift register 6 are H level, and the outputs QN+1-Q2N-1 are L level. In this state, all the outputs of NOR circuits 51-5N become L level and the same electric potential. The output of an inverter circuit 4 and the outputs of NOR circuits 5N+1-52N-1 depend on the level of an image signal 2. All the output terminals of these circuits become the same electric potential. If an image signal 1 is H level at this time, only the output of an inverter circuit 3 becomes H level. Therefore, an electric potential difference occurs between the output terminal of the inverter circuit 3 and the output terminal of the NOR circuit 51. Then, an electric current flows from the inverter circuit 3 to the NOR circuit 51 through a heating element 11, whereby the heating element 11 is driven.

Abstract: PROBLEM TO BE SOLVED: To measure the activity of sludge continuously in a stable state by mounting a gas concn. detection means on the upper part of a gas concn. detection column main body and forming a gas lead-out port to the bottom part of the column main body. SOLUTION: A gas concn. measuring apparatus is constituted of a cylindrical column main body 5a and the gas concn. detection means 6 airtightly mounted on the upper part thereof. A hole is formed to the bottom wall 5d of the main body 5a as a gas lead-out port 7b and the partial route 3B connected to a pump is connected thereto. When the pump is operated, high humidity gas is sucked into the partial route 3A and introduced into the main body 5a from a gas introducing port 7a and led out to the partial route 3B from the lead-out port 7b to be supplied to an aeration means. Therefore, a downward gas passage (q) from the side wall 5b of the main body 5b to the bottom wall 5d thereof is dominantly formed.  By this constitution, the chance of the direct contact of gas with a detection part 6a is reduced and the generation of such a state that moisture in gas is condensed on the detection part 6a is suppressed.
