Patent JP-S5735186-A (JP)
Title: Screw compressor
Inventor: TANAKA MASANORI
IPC: F04C18/16
Filed: 1980-08-08
Abstract: PURPOSE: To prevent drop of compression capacity by eliminating the over-compressed state through permitting the gas in the compression space to flow out to the discharge hole passing a check valve and by shutting the communication between the gas passage and compression chamber while there is no over-compression.  
     CONSTITUTION: When an over-compressed state is going to arise due to change of volumes of the male and female rotors 3, 4, the over-compressed gas opens immediately a check valve 36 to exhaust part of the high pressure gas in the compression chamber to the gas discharge hole 8 through an opening 31 and passage 30. Thus overcompression is hindered. When the over-compressed state is out, the check valve 36 is restituted to the closed position and the gas pressure of gas discharge hole 8 acts always on the gas passage 30, so that the check valve 36 blocks the compression chamber 1 from gas passage 30. Accordingly, compression and expansion of the gas in the compression chamber 1 is not transmitted to the gas staying in the gas passage 30, and thus drop of compression capacity can be prevented.

Title: Automatic self-support control device for fault detection
Inventor: YAMAGUCHI TOSHIYUKI
IPC: G05B9/02
Filed: 1979-08-27
Abstract: PURPOSE:To prevent previously the state of crisis for the control system, by detecting the high frequency component when the fault occurs and then carrying out the switching of the circuits. CONSTITUTION:When some fault occurs at either one of amplifiers AMP1-AMP4 at the control part 6, this falult is detected by the detecting circuit 7 which is connected immediately after occurrence of the fault. The the self-support control circuit part 9 is actuated immediately through the OR circuit 8 to ensure the self-support for the control signal at the early stage when no effect of the fault is given to the control signal. Thus the effect of the fault can be prevented from affecting the process 1. At the circuit 7 the integral network 71 extracts the high frequency component when the fault occurs, and the difference of signals is extracted through the deviation amplifier between the abnormal and normal states. Thus the deviation level during occurrence of the fault is heightened. The integral network 73 discriminates the fault signal from the noise signal from the time product. When the AMP1 generates the fault, the output causes the positive or negative step waveform signal. And the detecting circuit 71 detects the step waveform signal and then delivers the output to actuate the relay of the detecting part 9. Thus the control signal is held at the state which is before occurrence of the fault.

Title: Ink jet head
Inventor: NONOYAMA SHIGEO
IPC: B41J2/045
Filed: 1986-05-13
Abstract: PURPOSE:To prevent the clogging of a jet nozzle and the invasion of air bubbles into the nozzle, by a method wherein, the jet nozzle is communicated with an ink feeding chamber, and an outlet for discharging an ink out of the ink chamber is provided in the vicinity of the tip end of the jet nozzle. CONSTITUTION:An oil based ink 32 in an ink chamber 26 and a water based feeding liquid for ink 33 in an ink feeding liquid chamber 27 have the combination of water-soluble/oil-soluble properties. The ink does not exist usually within a jet nozzle 28 and at the tip end of the nozzle 28 being in contact with air, but only the ink feeding liquid 33 fills the nozzle 28. In a printing operation, a fixed amount of the ink 32 flows out of an ink outlet 29 of the ink chamber into the ink feeding liquid 33 in the vicinity of the nozzle 28, thus being jetted out of the jet nozzle 28 in a drip form together with the ink feeding liquid. In this manner, the concentration of the ink can be prevented even if the ink feeding liquid evaporates under a long-time non-printing condition.

Title: Hydrogen storage electrode
Inventor: SAKAI TETSUO
IPC: H01M4/24
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a hydrogen storage electrode having a high capacity and a high discharge rate by incorporating a specific element into a titanium - nickel alloy. SOLUTION: A hydrogen storage electrode comprises, as a constituent, a molding made of mixture powder including a titanium - nickel alloy containing oxygen. Although the titanium - nickel alloy containing oxygen is not particularly limited as long as oxygen (atoms) is incorporated into the Ti2 Ni alloy, it preferably has a composition expressed by a general formula: Ti4 Ni2 Ox (wherein 0.1<=x<=1.0, preferably, 0.3<=x<=0.8). If the content (x) of oxygen is less than 0.1, an effect owing to oxygen introduction becomes insufficient. In contrast, if the content x exceeds 1.0, a hydrogen dissociation pressure exceeds 1atom., thereby reducing charging efficiency, with a disadvantage of a decrease in capacity.
