Title: Four or six stage rolling stand having operation rolls supported on the side thereof
Inventor: GERUHARUTO KUMAAHOFU
IPC: B21B13/14
Filed: 1990-07-31
Abstract: PURPOSE: To decrease a risk of slip by supporting one lateral intermediate roll against one of two support rollers and the other lateral intermediate roll against the other support roller. CONSTITUTION: A first lateral intermediate roll 5 is supported at one side against a first support roller 6 having a relatively large area, at other side, is supported against a second lateral intermediate roll 7. The second lateral intermediate roll has a small diameter because it is supported in itself against a second support roller 8 and an intermediate roll 3 having relatively large support force. In addition to this advantage, torque is transmitted to the first lateral intermediate roll 5 from the intermediate roll 3 of a rolling stand through the second lateral intermediate roll 7. As a result, the torque is not transmitted by itself from a support point on a working roll 4 to the intermediate roll 5. By this arrangement, a risk of slip is considerably decreased particularly in accelerating.

Title: Ink jet recording head
Inventor: YASUTOMI HIDEO
IPC: B41J2/055
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a smooth image having high gradability like a photograph image by differentiating elastic moduli or thicknesses of partition walls of a plurality of heads. SOLUTION: Elastic moduli and thicknesses of partition wall 18a of a large- diameter head 12 and partition wall 18b of a small-diameter head 14 are differentiated. That is, in the case of the modulus, the wall 1a of the head 12 is reduced as compared with the wall 18b of the head 14. In the case of the thickness, the wall 18a of the head 12 is reduced smaller as compared with the wall 18b of the head 14. As a result, even if the same print signal is applied to a common electrode and individual electrodes, ink droplet discharged from a nozzle 28 if the head 12 is larger than that discharged from a nozzle 28 of the head 14. Accordingly, the head 12 or 14 is suitably selected in response to conditions of the image to be formed, and a voltage applied to the common electrode and the individual electrodes is altered, and hence gradability can be widely changed.

Title: Voltage controlling circuit for laser tube
Inventor: KOSHIZUKA MICHIO
IPC: H01S3/097
Filed: 1986-08-27
Abstract: PURPOSE:To restrain the power loss of a current controlling part to a minimum, by keeping the voltage applied to a current controlling part in a necessary high voltage range at the time when discharge starts, decreasing the voltage to a necessary lowest value after discharge, and controlling the current of a high voltage power source applying the necessary lowest voltage to a controlling voltage. CONSTITUTION:When the output voltage of a high voltage power source 12 is applied to a laser tube 10, discharge starts and a discharge current flows into a current controlling part 18. Then voltages determined by voltage dividing resistors R1-Rn are applied between respective drains and sources of a current controlling element TR1 and transient current controlling elements TR2-TRn. In this case, a condenser C is charged by a current flowing through resistors R1-Rn. As the result of this, gate voltages of elements TR2-TRn rise, and the voltage (nE-E) shared by each element (FET) is decreased, whose amount of decrease is burdened by the element TR1. The drain voltage E of the element TR1 is fed back to the high voltage power source 12, and compared with a reference voltage. Then a specified high voltage is output from the high voltage power source 12. Accordingly, the controlling voltage applied to the element TR1 is always kept constant.

Title: Ultraviolet reaction vessel
Inventor: FUKUSHIMA RYOSUKE
IPC: G01N27/06
Filed: 1993-07-24
Abstract: PURPOSE:To obtain an ultraviolet reactor having a compact structure and enhancing emission efficiency by providing an outer pipe, the coating film applied to the pipe wall thereof, low pressure mercury and a passage forming reaction pipe. CONSTITUTION:A pair of electrodes G, G bringing low pressure mercury 13 enclosed in a quartz outer pipe 11 to a plasma state by discharge to generate ultraviolet rays having a desired wavelength are provided to the respective end surfaces of the quartz outer pipe 11. An ultraviolet reaction vessel U is, for example, an ultraviolet light source emitting ultraviolet rays with a low wavelength of 185nm and can realize radical reaction advantageous to the decomposition of org. matter. Since the ultraviolet light source receives a synthetic quartz reaction tube 14 forming a spiral sample passage S, the vessel U becomes a compact structure. Since the inner wall of the outer pipe 11 has a mirror surface by an aluminum coating film 12, the leakage of harmful ultraviolet rays to the outside is prevented. By the even balance of the diameter of the passage S and the irradiation length of ultraviolet rays, reaction temp. is well controlled while the rise of ultraviolet density in the pipe is suppressed and emission efficiency is enhanced.

Filed: 1987-08-14
Abstract: PURPOSE:To enable a field-effect transistor having required characteristics to be manufactured in a reliable manner, by forming an oxynitride film in a gate insulating film before performing vapor growth of a semiconductor layer which is to provide a channel region after formation of the gate insulating film. CONSTITUTION:An oxynitride layer 15a having different etching properties from those of an oxide film 2 formed on the surface of a semiconductor substrate 1 on which a semiconductor layer is to be deposited by vapor growth is formed in a gate insulating film 15. When the oxide film 2 on the surface of the semiconductor substrate 1 is etched before depositing the semiconductor layer 6 by vapor growth, the gate insulating film 15 can be prevented from being etched thereby and hence any problem such as deterioration of characteristics can be avoided. Since the semiconductor layer 6 formed on the substrate 1 is thus allowed to have excellent crystallinity, it is possible to provide a field-effect transistor having uniform stability as required.

Title: Refrigerant liquid level controller inside cooling jacket in evaporative cooling device for internal-combustion engine
Inventor: ISHIHAMA MASAO
IPC: F01P3/22
Filed: 1984-09-29
Abstract: PURPOSE:To prevent the occurrence of overheating, by forcedly feeding a cooling jacket with a liquid phase refrigerant at a time when a refrigerant liquid level inside the cooling jacket falls short of a lower level than the level controlled by a liquid level controlling device. CONSTITUTION:A first liquid level sensor 32A comes out of order, and when a liquid level is erroneously detected that it is more than a first level, whereas it is less than the first level L1, such control as making a refrigerant liquid level go up is no longer carried out whereby the liquid level inside a cooling jacket 2 continues to go down. With this level dropping, if the liquid level drops beyond the setting level (a second level L2) of a second liquid level sensor 32B or the lower limit allowable value, this second liquid level sensor 32B comes to OFF whereby a continuous rating current to a coil 38b of a relay is cut off, while a control unit 31 senses an OFF signal so that such control as turning a power source to OFF with S112 takes place there. Therefore, a first solenoid valve 26 is closed while a third solenoid valve 24 is opened and under this condition the continuous rating current to the coil 38b is cut off whereby a contact 38a comes on, thus an auxiliary refrigerant feed pump 36 is energized with the current and driven.
