Title: Fluorescent lamp
Inventor: MATSUNO HIROMITSU
IPC: H01J61/10
Filed: 1986-03-10
Abstract: PURPOSE:To enhance the efficiency of a fluorescent lamp, by covering an electrode with a spherical hollow cover having an opening toward a positive column, to eliminate a Faraday dark space from which light is not emitted. CONSTITUTION:An electrode 3 is covered with a nearly-spherical hollow cover 8 having an opening 9 toward a positive column. The cover 8 is made of transparent glass and electrically insulated from the electrode 3. A fluorescent substance 10 is applied to the inside surface of the cover 8. The constitution of the spherical cover 8 is such that two hemispheres are stuck to each other without using another material and sandwich two lead wires supporting the electrode 3. As a result, most of the high-energy electrons in a negative glow 4 recombine on the inside surface of the spherical cover 8, and very few of the electrons diffuse through the opening 9. For that reason, a Faraday darks space is almost all eliminated so that the negative glow 4 and a positive column 6 are directly coupled to each other.

Title: Cooling method for semiconductor device
Inventor: TAKAHASHI EIJI
IPC: H01L23/367
Filed: 1980-04-18
Abstract: PURPOSE:To improve the thermal reliability of a semiconductor device by equalizing the radiating amounts on the cathode and anode sides. CONSTITUTION:By making the surface area of a heat sink 4 on the cathode side larger than that of a heat sink 5 on the anode side, the thermal resistance between the cathode-side heat sink 4 and the atmosphere is decreased. Consequently, the cathode-side thermal resistance decreases, so that the cathode side has the radiating effect equal to that of the anode side. It is also effect that the contact surface between the cathode and the heat sink is formed into a curved surface in order to increase area and decrease thermal resistance.

Title: Method and device for image recording
Inventor: KIMURA HIDEAKI
IPC: G06T5/20
Filed: 1989-03-01
Abstract: PURPOSE:To effectively perform the sharpness emphasizing process of an image signal without increasing memory capacity by setting the sampling pitch for reading image information out of an original image larger than a prescribed value. CONSTITUTION:An image signal which is read by scanning an original is processed by the image processing such as the sharpness emphasis and then scanned on a recording carrier by the image signal for recording. In this case, while the read is made at the sampling pitch larger than the prescribed sampling pitch, the recording is carried out at recording pitch corresponding to the prescribed sampling pitch. Therefore, the image processing such as the sharpness emphasis is carried out with mask size substantially larger than prescribed mask size. Consequently, the image processing is performed effectively without increasing the memory capacity for the image processing.
