Title: Active extending system for cable
Inventor: MATSUI TOSHIO
IPC: H04B3/00
Filed: 1987-09-18
Abstract: PURPOSE:To realize the smooth switch of a terminal resistance by switching a bias power supply after connecting a 1st diode in series to the terminal resistance of a 1st cable with a 2nd diode connected in parallel to said terminal resistance and then switching the polarity of the bias power supply part for active connection secured between 1st and 2nd cables. CONSTITUTION:A forward diode 11 is connected in series to a terminal resis tance 4 of a transmission system 10 and an adverse diode 12 is set in parallel between both transmission systems 10 and 20. When the polarity of a bias power supply 13 is kept as it is, the diode 11 is set forward with connection of the resistance 4. In this case, the diode 12 is set adverse with substantial separation of a terminal resistance 7. Thus the system 10 is never affected even though the connection is secured for the system 20 via a connector. When of the bias power supply 13 is switched, the diode 12 is set forward with connec tion the resistance 7 together with the diode 11 set adverse with no connection of the terminal 4 respectively. Thus the signals obtained by connection of the connector are free from the turbulance. Thus the terminal resistances are smooth ly switched in case a working active transmission system is connected to a 2nd cable transmission system via a connector.

IPC: G05B19/404
Filed: 1989-09-12
Abstract: PURPOSE:To change the operation into a mode where a robot arm functions as a spring with no movement by setting again a track command, i.e., the spring center position attitude based on the force/torque applied to a present finger effect device an a spring constant. CONSTITUTION:A track generating part 9 is provided to produce a position attitude command for movement of a robot arm 1 together with a force/torque sensor 2 which measures the force/torque that is applied to a subject fixed to the arm 1, a control means which actuates the arm 1 as a spring having a designated spring constant based on the position attitude command of the part 9, and an instruction means 10 which instructs a valid or invalid spring action. When an instruction is produced to change an invalid spring action into the valid one, the spring center position attitude is obtained from the force/ torque measurement value and the designated spring constant and used as a command of the part 9. Thus it is possible to set a mode where the arm 1 functions as a spring with no movement of the arm 1 in spite of whatever force/torque is applied from the subject.

Title: Molten metal reservoir for melting metal
Inventor: BURUFU BUREEMAA
IPC: F27D3/14
Filed: 1989-09-12
Abstract: PURPOSE: To measure the temperature of melt accurately by locating both an opening and a thermosensor below the mirror surface of the melt when the thermosensor provided with a protective coating part plunges into the wall part of a melting trough through the opening. CONSTITUTION: A protective pipe 3 is dispose directly above the opening of a capillary cast passage 2 in a melt trough 1 while plunging into the wall part thereof through an opening 8. A thermosensor 3 is separated, at most 2 mm, from the passage 2 or the inner wall of the tunnel type melt trough 1. Consequently, gravity acts in addition to the pressure of gaseous atmosphere at the time of casting process. Since a capillary casting passage is employed, a material melted by surface tension is prevented, by gas pressure, from entering through the passage 2 during a melting process. Since the forward end part of the thermosensor 3 plunges into the melt, temperature of the melt can be measured accurately.

Title: Acoustic wave probe
Inventor: UMEMOTO KOSHI
IPC: G01N29/00
Filed: 1985-10-23
Abstract: PURPOSE:To eliminate trouble due to the reflection of an ultrasonic wave in an acoustic lens and to prevent the ultrasonic wave from attenuating in the acoustic wave lens by forming the whole acoustic lens body conically. CONSTITUTION:The acoustic lens 1 is composed of an acoustic wave propagation body formed conically on the whole. An ultrasonic wave 7 which is oscillated by a piezoelectric element 2 into the lens 1 and reaches its spherical surface part 8 is reflected by a sample 9 and transmitted as a video signal 13 to a display body 14. An ultrasonic wave 7 which reaches a position off the spherical surface part 8 is reflected by the curved surface part of the acoustic lens 1 to the peripheral part of the plane part. Consequently, the possibility of the reflected ultrasonic wave 7 reaches the piezoelectric element 2 is decreased greatly and the adverse influence of the reflected ultrasonic wave 7 is eliminated.

Inventor: NAKAJIMA HARUKI
IPC: H04N5/44
Filed: 1990-09-04
Abstract: PURPOSE:To decide a video signal by means of a digital processing by deciding the presence or absence of the video signal by counting the number of horizontal synchronizing signal in one vertical scan period and deciding whether the count value is within a prescribed range decided by means of upper/lower limit values. CONSTITUTION:The number of the horizontal synchronizing signal for the prescribed period which is set by a monostable multivibrator 1 is counted by a counter 4 and the presence or absence of the video signal is judged whether the count value is within then range of the lower limit value n1 and the upper limit value n2 by the comparison by the comparator 6. Since the configuration of a video signal presence/absence deciding circuit is thus made, the presence or absence of the video signal can be decided by the digital processing. Thus, the circuit can be highly integrated.

Title: Ink-jet recording head, ink-jet recording head cartridge, and ink-jet recording apparatus
Inventor: INOUE RYOJI
IPC: B41J2/175
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To prevent air bubbles from growing rearwards, extruding from nozzles, being divided at a refill time and remaining in a common liquid chamber. SOLUTION: An inclined part 107 increasing a height rearwards is formed between a rear end of a heater 103 and a feed port 106. When heaters 102 and 103 are driven to discharge ink from a discharge part 104, generated air bubbles are hard to extrude from a common liquid chamber 105 owing to the inclined part 107 of a large volume even if the air bubbles grow rearwards. When ink is refilled, the ink smoothly flows owing to the inclined part 107 without dividing the air bubbles having grown rearwards. At this time, the ink hardly flows at a part more frontward than a part where an extension face of the inclined part 107 intersects with a ceiling part of an air bubble trap 110, and therefore resident air bubbles 111 are hard to flow backwards into a nozzle 101.

Title: Mis field effect transistor and driving method thereof
Inventor: KUNIO TAKEMITSU
IPC: H01L29/78
Filed: 1985-10-21
Abstract: PURPOSE:To prevent the kink phenomenon by bringing at least a part of a channel region existing under a gate electrode in contact with a semiconductor substrate and arranging source and drain regions in a semiconductor thin film on an insulating film located on the semiconductor substrate. CONSTITUTION:This N-channel MOSFET comprises four terminals of a drain electrode 11, a source electrode 12, a gate electrode 13, and a semiconductor substrate electrode 14. The semiconductor substrate electrode 14 can be predetermined at an arbitrary potential through a conductor 15. For example, 5V is applied to the gate electrode 13 so as to change a voltage of the drain electrode 12 from 0V to 5V. At that time, if a potential of the semi-conductor substrate electrode 14 has been floated, minority carriers are produced in a semiconductor thin film under a channel region to cause the change of the potential of the semiconductor substrate, and the kink phenomenon takes place in a pentode region of drain current-drain voltage characteristic. However, if the semiconductor substrate electrode 14 is predetermined at an arbitrary potential, for example, 0V, minority carriers flow out to the semiconductor substrate electrode 14 and the potential of the semiconductor substrate can be kept at 0V. Accordingly, the kink phenomenon is not produced and the potential of the substrate can be fixed by the potential applied to the semiconductor substrate electrode 14.

Title: Flow control device on group of master and slave valves
Inventor: IWATO MOTORO
IPC: F02C9/20
Filed: 1985-10-24
Abstract: PURPOSE:To make more wide valve open points than available from the total number of valves, and reduce a possible valve throttling loss by controlling a medium flow amount through two types of valve group made of master valve group comprising several reducing valves and a slave valve group wherein a flow amount corresponding to a single master valve is separated into several slave valves. CONSTITUTION:Steam regulating valves are separated into a master valve group A and a slave valve group B, and steam is introduced into the nozzle chamber 3 and the nozzle 2 of each valve. In this case, the master valve 5 of the master valve group A is always kept wide open or totally closed at the time of turbine operation and operated in principle only when changed over to the slave valve group B. On the other hand, another slave valve group C as a whole is made to have much the same capacity as a single master valve and the normal load or steam fluctuation thereof is controlled by opening and closing the slave valve group B. The illustration herein shows the case wherein Nos. 1 and 2 of master valves 5 and Nos. 1 and 2 of slave valves 11 are respectively wide open, and only Nos. 3 and 3 thereof are half open. If the capacity of a single slave valve is a quarter of a single master valve, a total steam flow amount becomes about 2.6-2.7 times as large as that available from a single master valve. A steam flow amount in wide opening is 2.5 times as large.
