Title: Electron gun for picture tube
Inventor: KUMADA SEIJI
IPC: H01J29/48
Filed: 1990-10-03
Abstract: PURPOSE:To inhibit the generation of grid emission, and to obtain an electron gun for picture tube, which is composed of an electrode that has no possibility of side effect, at a low cost by having an active metal included in an electrode material preferentially oxidated on the surface of the electrode, and by forming the electron gun out of an electrode, for which the oxide layer of the active metal is formed in a discontinuous manner on the surface. CONSTITUTION:By preferentially oxidating an active metal such as Si, Mn, Cr and so on, included by a small amount in an electrode material, on an electrode surface 1, an electron gun is formed out of an electrode for which an oxide layer 2 of the active metal is formed in a discontinuous manner on the surface. Even when Ba, BaO and the like evaporated from a cathode adhere to the electrode surface 1, the activation thereof is little, and since the reduction in work function is inhibited, the generation of grid emission is inhibited. Since the layer 2 of the oxide thus formed is in a discontinuous mode, the side effect such that the electric field distribution in the vicinity of the electrode is varied, will rarely occur. The generation of grid emission from the electrode can be inhibited, and an electron gun for picture tube, composed of an electrode that has no possibility of side effect, can thus be obtained at a low cost.

Filed: 1987-10-21
Abstract: PURPOSE:To make it possible to try saving of fuel and damping noise by controlling an engine speed by means of an actuator on the basis of an inverter load current detection signal and a generator voltage detection signal. CONSTITUTION:Electric power generated by a generator 3 is supplied to an inverter unit 4 to be used as an external power supply by means of a socket 9 and a signal from an electric current sensor 6 installed between the generator 3 and the inverter unit 4 is supplied to a controller unit 7 as a load current detection signal of the inverter unit 4. Also, a voltage detection signal from the generator 3 is supplied to the controller unit 7. The controller unit 7 supplies a control drive signal to an actuator 8 on the basis of each detected signal to control an engine speed. Thus, the position of a thrust shaft 33 is detected by signals from detectors so as to return the engine speed certainly to its idling state in such conditions as providing possibility for generating power sufficiently in the idling state, or as providing inoperative state of a power generation mechanism 1.

Title: Work profiling method in laser beam machine, its device and laser machining head
Inventor: SHIOJI KOMEI
IPC: B23K26/046
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce a flaw generating in a work by minimizing a contact part of a work contactor, reducing the change of a gap between a tip end of a nozzle and the work owing to an inclination of the work and reducing a required crosspiece width. SOLUTION: A sensor nozzle 5 which is combined with a non-contact type sensor detecting a distance from a conductive body is provided in a tip end of a laser machining head 1, and a nonconductive guide body 15 is provided in a tip end of the sensor nozzle 5. A contacting nozzle 21 consisting of the conductive body is provided in the guide body 15 so as to freely approach, separate and move vertically with respect to a tip end surface 13 of the sensor nozzle 5. A tip end of the contacting nozzle 21 is brought into contact with the work W consisting of an insulator. The laser machining head 1 is vertically moved so that a distance between the sensor nozzle 5 and the contact nozzle 21 is controlled to be constant with a controller based on the detected distance by the sensor nozzle 5.  Since a diameter of the tip end of the contacting nozzle 21 is considerably small, the flaw in the work is largely reduced, the crosspiece width is reduced and a stable laser beam machining which is not affected by the inclination of the work W is executed.

Title: Seal container
Inventor: SAKAI YUSUKE
IPC: B65D81/34
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To obtain a seal container suitable to fragrant food or steamed food by providing, in an internal space formed by a container body and a lid, a hermetic package which automatically unseals with an internal pressure rising by heating by a microwave oven to diffuse fragrant constituents outside. SOLUTION: When the seal container is placed in a microwave oven and heating of the seal container 1 is started, moisture in nonwoven fabric 6 impregnated therewith of a hermetic package 4 begins to vaporize to have an internal pressure of the hermetic package 4 increased to cause an entire outer package 5 to swell. Moisture contained in a cooking substance X in a container body begins to vaporize to rise the internal pressure in the container body, thereby causing a lid to swell outward. The internal pressure in the container body and the outer package 5 rises, a back seal 8 and/or end rim seals 9, 10 begins to peel on the outer package 5, and when peeling reaches a tip of the seals, vaporized moisture and fragrant constituents are discharged outside. Thus the fragrant constituents can be entirely and evenly spread over cooked food.

Title: Image processing unit
Inventor: KUMASHIRO HIDEO
IPC: H04N1/405
Filed: 1994-10-28
Abstract: PURPOSE: To attain the diffusion of error at a high speed by converting received picture element data with N1 value into dither image data with N2 value and discriminating the attribute of the image so as to diffuse the error of a mean image density and dither image data thereby avoiding the occurrence of a stripe pattern specific to the computer graphics or the like. CONSTITUTION: A multi-valued dither circuit 11 of an image processing circuit 10 converts 8-bit input image data f1 into 4-bit dither image data f2. An error correction section 12 applies error correction for error diffusion to the dither image data f2. An attribute discrimination section 17 receives the data f2 to discriminate distributed state of the image based on a maximum/minimum value of a local area. An adjustment section 18 adjusts error correction data for error diffusion depending on the result of discrimination by the discrimination section 17. Thus, error diffusion depending on the attribute of the image is controlled and the image processing utilizing the advantages of both the dither error diffusion and the binarizing mean density error diffusion for the image processing is attained.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a high-quality, high- productivity and inexpensive assembly mounted with a semiconductor part, a method for manufacturing a finished product mounted with a semiconductor part, and a finished product mounted with a semiconductor part. SOLUTION: A semiconductor element 114 is buried in a first thermoelestic resin substrate 122, and a circuit pattern 116 is formed on the buried semiconductor element 114, thereby completing the mounting.
