Title: Manufacture of metal halide lamp
Inventor: MATSUNO HIROMITSU
IPC: H01J9/395
Filed: 1981-01-21
Abstract: PURPOSE:To prevent any variety in the color of the light of a metal halide lamp by charging a rare earth metal and mercuric iodide separately into an emission tube, and placing the said rare earth metal on a part of the wall of the tube which is not coated with a heat insulating film, which is applied to the ends of the tube, and heating the tube so as to produce an iodide of the said rare earth metal. CONSTITUTION:An emission tube 2 is charged with Dy metal pieces, HgI2, TlI, NaI, CsI, Hg and Ar. Next, after the Dy metal pieces are moved to a sealed off part 4, the Dy metal pieces are heated in vacuum while maintaining the tube 2 horizontal, with the part 4 located in the downside of the tube 2, so as to produce an iodide of Dy metal. After that, ZrO2 powder used as heat insulating films 3 and 3' is applied to both ends of the tube 2, and the tube 2 is charged in an outer tubular bulb. Consequently, a metal halide lamp with high quality can be obtained.

Filed: 1990-01-17
Abstract: PURPOSE: To surely perform the tearing process by providing a lid part with a weakened line inside a sealing line to a lower part, and providing a bond face of both parts with a longitudinal portion narrowly defined. CONSTITUTION: A lower part and a lid part are made of, e.g. a metalic film 112 and a plastic film 113, and both parts are closely bonded through a face along a seal line. A part 117 of a bridging piece 115 has an ordinary width, and its seal line 117a has also an ordinary width. By reducing the width of the bridging piece 115 in a selected longitudinal range such as a part 116, the sticking force of this part is reduced, and a lid film 111 is separated from the bridging piece part 116. Accordingly, by defining a tab piece by a weakened line on the lid part, and bonding the tab piece to a tear range 139 of the lid part 135 at the other side of the bridging piece, the tear range 139 can be torn by the tab, and the lid part can be separated.

Abstract: PURPOSE:To simplify a system and to reduce the cost of the system by bidirectionally transmitting an information signal between a first device and a second device by one transmission line. CONSTITUTION:In a video camera part, frequency multiplexing is executed to a picture signal V, which is formed in correspondence to a picture to be image-formed by an image pickup lens 1b in a video camera 1, and a sound signal A outputted from a microphone 1a.

Filed: 1987-01-14
Abstract: PURPOSE:To detect dust at high speed even in image which has the great number of data by providing a grid elimination process before dividing the image into some area, eliminating grids and leaving only the dust behind. CONSTITUTION:The image is converted with the aid of a two dimensional filter which has an operator coefficient as a figure (a) shows.

Title: Developing method in two color copying system
Inventor: MATSUMOTO FUYUHIKO
IPC: G03G13/01
Filed: 1980-01-25
Abstract: PURPOSE:To prevent defects due to the edge effect of a toner image, by rendering volume resistivity of the magnetic powder carrier of the first toner different from that of the second toner in developing static latent images different from each other in polarity on a latent image bearing body with 2 color toners different from each other in charge polarity. CONSTITUTION:For example, a negative latent image on the surface of photoreceptor 1 as a latent image bearing body is developed with black toner TBL, and a positive latent image with red toner TR. When the latent image is developed with the first toner TR and then, the other latent image is developed with the second toner TBL, red border R1 occurs around black image BL1 with white ground W1 between them on account of the edge effect. In order to prevent border R1, volume resistivity of a magnetic powder carrier used with toner TBL is made in 10<5>- 10<8>OMEGAcm, and that of the carrier used with toner TR is made in 10<10>-10<11>OMEGAcm. As a result, it is prevented that the latent image to be developed with toner TBL causes charge leakage due to the carrier of toner TR, and undergoes deformation, thus permitting the edge effect to be prevented.
