Title: Display element
Inventor: MAEDA TSUYOSHI
IPC: G02F1/1335
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain a semitransmission type and bright reflection type liquid crystal element and to realize multicolor display by arranging 1st and 2nd specified polarizing splitting means on both sides of a transmissive polarization axis varying means and using a colored light source. SOLUTION: TN liquid crystal panels 22 to 26 are used as a transmissive polarization axis varying optical element, and a blue color polarizing plate 12 is provided above the panels 22 to 26, and then a light scattering body 30, a polarizing splitter 40 and a red EL backlight 60 are provided below the panels 22 to 26 in this order. As for the reflection type display at the time when external light is made incident; blue display is performed at a voltage non-impressing part (polarized light 13 and 14) and white display is performed at a voltage impressing part (polarized light 15 and 16).  As for the transmission type display by the light from the backlight 60; black display is performed because red colored light from the backlight 60 is absorbed by the plate 12 at the voltage impressing part (polarized light 18), and red display is performed because it is transmitted through the plate 12 at the voltage non-impressing part (polarized light 17).

Title: Controller and control method for electric vehicle
Inventor: TANAMACHI TOKUNOSUKE
IPC: H02P27/06
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To accelerate/decelerate a vehicle by torque corresponding to a current command by a method wherein the hourly change rate command of the output frequency of an inverter is so controlled as to make an inverter output current be the current command. SOLUTION: An inverter output current Im is made to be equal to a current command Ip by the output Δαi of a current controller 62. That is, the increment of an inverter output frequency command Fin in accordance with a frequency hourly change rate command α is made to be equal to the increments of the rotation frequencies Fr1-Fr4 of induction motors 31-34 and the slip frequencies of the induction motors 31-34 are made to be constant. Then, the frequency hourly change rate command α is made to correspond to the current instruction Ip (≈ inverter output current Im). With this constitution, an overcurrent is hardly produced and, further, a vehicle is accelerated/decelerated by torque corresponding to the current command Ip.

Filed: 1990-05-09
Abstract: PURPOSE:To analyze an element which forms a fine region having a high in- plane resolving power by providing an X ray image detection means which has either a positional resolving power or an energy resolving power or both. CONSTITUTION:Thermoelectrons emitted from an electron gun 101 are focussed by a focussing lens 102 where the electrons are deflected by a polariscope 103 and reduced by an objective lens, and radiated uniformly to a sample 105 mounted on an X-Y stage 109.

Abstract: PURPOSE:To obtain the shield effect equal to that obtained when the whole is formed of an expensive material, by forming a strip form ring part constituted of a material more excellent in a shield characteristic to the central part of a slice collimetor in the radius direction thereof. CONSTITUTION:A slice collimator ring 12 is constituted of led having a uniform thickness and strip like ring parts 13 composed of tungsten are provided to both side surfaces of the central part thereof.

Further, since gamma-rays (d) also pass through the adjacent slice collimator, they are sufficiently shielded. By this method, the shield effect the same to that obtained when the whole is formed of an expensive material can be obtained.

Title: Printing machine equipped with sheet-shaped material supply and positioning mechanism
Inventor: MAAKU GATSUKIN
IPC: B41J3/44
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To execute accurate and stable multicolor printing by providing a means to position a sheetlike material in relation to a print head independently from a feeding means to drive a platen. SOLUTION: A sheet material S and an ink ribbon are pressed to the full length of a platen 40 in the axial direction thereof by a print head and delivered by the rotation of the platen 40 driven by a platen drive motor 64 in a pressed state. On the other hand, during printing work, a sprocket 46 is not a means to actively perform the feeding of the sheet material S but engages with a feed hole H and guides the sheet material S and adjusts the direction. Correct positioning of the sheet material S in relation to the print head can be made continuously by preventing the sheet material S from drifting away from the delivery direction thereof during delivery by the platen 40. Thus accurate and stable printing is ensured even in multicolor printing.

Title: Pump water falling preventing device
Inventor: MANABE AKIRA
IPC: F04D9/04
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent advance of air toward a pump so as to prevent falling of water by arranging a closing valve for shutting out flow of air reserved in a delivery pipe side when a delivery valve is opened, in a direction perpendicular to a flow passage. SOLUTION: At a time when a pump 1 is started to reach delivery pressure which is necessary for forming siphon action, a part of air rested in a delivery pipe 3 when water makes flow from a clearance of a valve element 10 into a delivery pipe 3 by opening a delivery valve 4, flows in a reverse direction from the clearance of the valve element 10. A flow passage is closed by a close plate 12 whose vertical direction length is about from 1/4 to 1/2 of a piping diameter and width of a horizontal direction is a pipe diameter or more, and thereby, reverse flow of air is obstructed so as to stay air to a downstream side of the close plate 12.  After that, when a flow rate of water is increased as an opening of the delivery valve 4 is opened largely, the flow rate of water is increased more than a reverse flow rate of air, and thereby, air is finally pushed out by flow of water so as to form a siphon water passage.

Title: Image sensor
Inventor: ITO TAKAFUMI
IPC: H04N5/335
Filed: 1987-05-15
Abstract: PURPOSE:To restrain the deviation of a focal point due to the dispersion of a sensor in thickness by a method wherein the dispersion of the sensor in thickness is rendered smaller than a specified value, where the sensor is structured in such a manner that a photoelectric conversion element is mounted on a glass substrate through which a light ray is incident. CONSTITUTION:An image sensor is structured in such a manner that a photoelectric conversion element 1 consisting of a glass provided with a light sensitive layer and an electrode 6 thereon is mounted on a glass substrate 2 through which a light ray 3 is incident. In the sensor structured as mentioned above, the substrate 2 is used which is smaller than + or -0.2 mm in thickness dispersion. The thickness tolerance of the substrate 2 through which the incident light ray 3 passes is rendered + or -0.2 mm, wherefore the resolution of an image pick-up unit depends on only performance of a rod lens array. By these processes, the deviation of a focal point owing to the thickness dispersion can be restrained, and thus an image sensor excellent in resolution can be obtained.

Title: Light guide line detection device
Inventor: NOMURA MASAKATSU
IPC: G05D1/02
Filed: 1991-05-23
Abstract: PURPOSE:To precisely detect a light guide line for guiding an unmanned vehicle. CONSTITUTION:A line sensor 4 receives light reflected by a road surface 1 and a light reflecting tape 2 and outputs a line sensor signal A whose value corresponds to the quantity of light reception. This line sensor signal A is compared by a comparator 6 with a threshold level and converted into a binary- coded signal. A position computing element 7 operates the position of the light reflecting tape 2 from the width and position of a high-level section of the binary-coded signal. In this case, if there is a part or metal piece with a high reflection factor on the road surface 1, binary-coded signals corresponding to them are ignored. Even if the light reflecting tape 2 becomes narrow in reflection width owing to damage, etc., the binary-coded signal corresponding to the light reflecting tape 2 is obtained to find the tape position.
