Title: Substrate for information recording and its production
Inventor: KIMURA TOSHIO
IPC: G11B7/24015
Filed: 1987-07-27
Abstract: PURPOSE:To decrease residual strains and to prevent warpage by disposing projections of at least either of an outside circumferential spacer and inside circumferential spacer to a discontinuous annular shape. CONSTITUTION:A substrate 1 is constituted by disposing two sheets of disk substrates 3a, 3b to face each other with recording medium layers 4a, 4b positioned on the inner side and sticking the substrates via the outside circumferential spacer 5 and the inside circumferential spacer 6. The substrates are welded by welded parts 8 which are ultrasonically welded in the projecting parts provided on respective both sides and are thereby changed from the projections. The projections of the outside circumferential spacer 5 and the inside circumferential spacer 6 which constitute the welded parts 8 are discontinuous and are uniformly disposed to the annular shape. The internal stresses remaining in the substrates are thereby decreased and the warpage is prevented.

Title: Particulate trapping device and sealing material therefor
Inventor: SEKI MASANORI
IPC: F01N3/023
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To obviate dust leakage in spite of the presence of moisture, etc., by disposing inorg. mats which are subjected to a waterproof treatment and contain components expanding at the time of heating on the surface side of the frame part of a bored shape frame where the sealing material of a particulate trapping device for regenerating a filter by generating a backflow gas comes into contact with the upper and lower surface filters. SOLUTION: The introduction of the dust-laden gas is stopped in order to remove the particulates captured by the filter 2 and to regenerate the filter 2. A back washing valve 7 near a cleaning gas outflow member is opened to rapidly introduce the back washing gas from an introducing port 8. The back washing gas is sent from the cleaning gas flow passage side via the filter walls to the dust-laden gas flow passage side. The particulates are desorbed from the filter walls and are passed through the dust-laden gas flow passage extending in a longitudinal direction. The particulates are then dropped into a lower particulate receiving section 9 and are ignited and burned to ash by a seal heater 10. The ash is taken out of an ash take-out port 11. The inorg. materials and sealing materials are subjected to a waterproof treatment.  As a result, there is no absorption of the moisture and even if there is the moisture in the waste gases and the device, the deterioration of the restoration performance of the inorg. mats is averted and the dust leakage is prevented.

Title: Solid image pickup device
Inventor: KURODA TAKAO
IPC: H04N5/335
Filed: 1980-12-25
Abstract: PURPOSE:To easily manufacture a device and to efficiently discharge excess charge to the outside, by providing an excess charge discharge means corresponding to each photoelectric converting part. CONSTITUTION:Each excess charge discharging impurity layer 8 is provided independently, corresponding to each photoelectric converting part 1. Each layer 8 is electrically connected through a contact hole 21 to an Al layer 10 provided on a vertical transfer shift register. Excess charge which has overflowed to the layer 8 is discharged to the outside directly from the layer through the layer 10. According to this constitution, after gate electrodes 4-7 of each vertical CCD, a transfer gate electrode 2 and an excess charge discharging control gate 9 have been formed, the converting part 1 and an impurity layer of the layer 8 are formed by the same impurity leading-in process. Accordingly, since the layer 8 can be formed by means of self-matching diffusion, non-uniformity of channel length can be controlled. Also, since the excess charge is discharged directly to the outside, the discharge capacity is sufficient even if the quantity of excess charge has increased.
