Title: Manufacturing method of semi-open type impeller
Inventor: KAJIWARA KENICHI
IPC: F04D29/22
Filed: 1978-04-17
Abstract: PURPOSE: To greatly reduce the leak loss of a semi-open type impeller, by bending a portion of a blade extended from a main plate of an impeller toward a side plate to form the second portion extended in parallel to the side plate and thus expanding the width of the blade's front rim.  
     CONSTITUTION: A main plate 1 and blade 2 are made of steel plate. A cylindrical body having the first portion 2a extended from the main plate 1 toward the side plate and also having the second portion 2b bent from the first portion 2a to the direction in parallel with the side plate is formed of the steel plate. This cylindrical body is divided, for example, into four to form a blade. A flange 2c is also formed at the moment of the working to the rim of the first portion 2a and welded to the main plate 1. The blade of such construction with the first and second portions 2a, 2b is very large in width and can greatly reduce the leak loss of the impeller.

Title: Resin film peeling method for cathode-ray tube
Inventor: KENMOTSU SHIROU
IPC: B05C9/10
Filed: 1994-03-15
Abstract: PURPOSE:To facilitate peeling work of a resin film. CONSTITUTION:In peeling a surface flattening resin film 22 bonded on a panel surface 14a of a cathode-ray tube 10, a resin peeling liquid 36 is penetrated into part of an interface 34 between the panel surface 14a and the resin film 22 so that the end of the resin film 22 is peeled in a state where bonding force between the panel surface 14a and the resin film 22 is weakened. When the resin film 22 is gradually peeled while charging the resin peeling liquid 36 between the peeled end of the resin film and the panel surface 14a, the resin film 22 can be completely peeled from the panel surface 14a without the residual resin. This is because hydrogen bonding force between the resin and a cleansing liquid becomes stronger with application of the cleansing liquid while hydrogen bonding force between the glass surface of the panel and the resin becomes weaker in that degree.

Title: Optical writing element
Inventor: SHIMIZU YUKIHIKO
IPC: H01J31/15
Filed: 1995-03-03
Abstract: PURPOSE: To provide an optical writing element wherein fluctuation in quantity of light of luminous dots is small. CONSTITUTION: On an inner face of an anode substrate 2 of an envelope 4, luminous dots 8 are arranged in a staggering shape in two rows. In between the two rows of the luminous dots 8 and in between wiring conductors 6 of the luminous dots 8, band-like control electrodes are provided. On each of the two rows of the luminous dots 8, a cathode 22 is provided. The wiring conductors 6 to be connected to the luminous dots 8 and the outward part of the upper face of the anode substrate 2 are covered with an insulating layer 12. A driver IC 13 arranged on the insulating layer 12 and the wiring conductors 6 are connected by a wire 15. On an edge part 12a of the inside of the insulating layer 12, shielding members 21 are provided. The shielding member 21 is higher than the interval between the luminous dot 8 and the cathode 22.  As the shielding members 21 partition the most part of the insulating layer 12 and the luminous dots 8, an electron charged on the insulating layer 12 does not change the quantity of light of the luminous dots 8. As the shielding members 21 shield the wire 15 and the luminous dots 8, the electric field of the wire 15 does not change the quantity of light of the luminous dots 8.

Title: Heat exchanger of horizontal lamination type
Inventor: SASAKI HIRONAKA
IPC: F28D1/03
Filed: 1986-02-28
Abstract: PURPOSE:To obtain a heat exchanger of lamination type which has sufficient strength against internal and external pressures applied to its tube elements by constituting the tube element by connecting a pair of formed plates with the peripheral section of an intermediate plate with inner fins positioned between the pair of formed plates. CONSTITUTION:This tube element is formed by connecting a pair of an upper formed plate 11 and a lower formed plate 11 which open on one face and have pan shape with an intermediate plate 12 positioned between those formed plates 11 and 11. On the other hand the intermediate plate 12 has an outer shape which follows along the peripheral edge of the formed plate 11, and only both side edges 12a and 12a are made to be larger than the whole width of the formed plate 11 so that they project from the edges of the connecting face 13 of the formed plates 11 when they are in the state of connection. The intermediate plate 12 has an inner fin section 12b provided at the flat section of the tube element in order to increase heat exchanging efficiency. Because the intermediate plate becomes a reinforcing element, the heat exchanger is excellent in resistance against pressure and durability.

Abstract: PURPOSE:To improve control accuracy ever so better, by letting a controller compensate a duty ratio in a driving pulse signal for controlling a solenoid valve according to a driving voltage level of the solenoid valve for time use, in case of the controller that controls the injection timing of fuel with a closed- loop control system. CONSTITUTION:Engine speed data N is found out of a top dead center pulse TDC from a reference timing sensor at a speed operational part 21, and the output is inputted into each of desired injection timing and actual injection timing operational parts 22 and 23. Next, each output out of these operational parts 22 and 23 is inputted into an error detecting part 24, detecting a difference between the desired injection timing and the actual injection timing, and the detected result is given to a duty ratio operational part 26 via a PI operational part 25. Hereat, a duty ratio in a driving pulse signal to secure an operated variable of a timer for injection timing adjustment necessary for setting this difference portion to zero is operated. Then, the duty ratio is compensated by a compensating part according to a driving voltage level of a solenoid valve for timer use, and the solenoid valve is controlled on the basis of the duty ratio after compensation.

Title: Gate prpotecting circuit
Inventor: MURAYAMA KOUJI
IPC: H03K19/003
Filed: 1982-03-20
Abstract: PURPOSE:To improve the protecting function of a gate protecting circuit by connecting a semiconductor element having a withstand voltage lower than the gate breakdown voltage at the gate of a protecting transistor, thereby preventing the gate breakdown of the transistor. CONSTITUTION:When an excess input is applied to an input terminal IN, a transistor T6 instantaneously turns ON, and a transistor T5 turns On in ressponse to the voltage the obtained by substracting the threshold voltage of the transistor T6 from the input voltage. Thus, low voltage obtained by dividing the input voltage by the input resistance R and the ON resistance of the transistor T5 is applied to the gate of the transistor T, thereby performing the protection of the gate of the transistor T. Since a transistor T7 having a withstand voltage lower than the gate breakdown voltage is connected to the gate of the transistor T5 even if the input voltage is very high, the gate insulation breakdown of the T5 can be prevented in advance. In this case, since it is not necessary to form the transistor T7 so that the ON resistance is low, the size can be reduced.

Title: Laminated core for motor
Inventor: UETOKO TAKEO
IPC: H02K1/12
Filed: 1981-03-26
Abstract: PURPOSE:To improve a magnetic circuit without taking up the accuracy of processing as a problem by removing arbitrary one part number among laminating, forming air gaps detaching sections among magnetic poles constituted to remaining laminated cores and conducting laminating, stacking and fastening. CONSTITUTION:h-Sections are detached and the air gaps alpha are formed, and the detachment is not conducted about some number of laminated plates. Since the h sections of most of laminated plates are detached, reactive magnetic flux cannot pass the h sections by the air gaps alpha particularly larger than air gaps, and can be reduced remarkably. Since the air gaps alpha may be made particularly larger than the air gaps, machining for fining the h sections after punching processing can be unnecessitated. Accordingly, the efficiency of the magnetic circuit can be improved without taking up the accuracy of processing as a problem.
