Inventor: ISONO MICHIKAZU
IPC: H01R4/64
Filed: 1989-03-27
Abstract: PURPOSE:To reduce the number of installing process by providing cut-up pawls of different lengths on an elastic earth metal fitting. CONSTITUTION:A one-touch type earth metal fitting 1 of an elastic body is bent in a U-shape, and a pair of pawls (1) 3, a pair of pawls (2) 4, and a pair of pawls (3) 5, cut up in different lengths, are provided on the opposite sides of the metal fitting 1. In an installing plate 6 to install the metal fitting 1, rectangular holes 7 are arranged. By pressing in the pairs of pawls 3, 4, and 5 of the metal fitting 1 to the holes 7, the metal fitting 1 can be installed to the plate 6 in one touch. Since the earth metal fitting can be installed in one touch in such a way, it is effective to reduce the number of installing process. And since the lengths of the pawls are different each other, some pair of pawls are hooked to the rectangular holes and the other pairs of pawls are not responding to the thickness of the plate, and the pawls not hooked but expanded are used as a stopper. Consequently, the earth metal fitting is not necessary to provide responding to the thickness of the installing plate respectively, and the cost can be reduced.

Title: Combustion device
Inventor: HIRATA YASUSHI
IPC: F23L17/14
Filed: 1984-04-11
Abstract: PURPOSE:To prevent odor pollution from occurring by absorbingly removing the odor constituents such as aldehydes, ketones and the like, which develop in large quantities at the setting-on and putting-out of fire, by a method wherein water abosrbing substance is arranged in an discharge passage, through which exhaust gas developed at a combustion section flows. CONSTITUTION:The air sucked through supply air ports is mixed with kerosene and burnt at a combustion section. The resultant exhaust gas is past through water absorbing substance 6 and discharged outdoors through exhaust ports 7. At this time, aldehydes, ketones, hydrocarbon, and carbon monoxide are absorbed in the bedewed water of the water absorbing substance 6. Especially, because aldehydes such as formaldehyde, acetaldehyde and the like, which are main causes of odor development, are water-soluble, almost all the aldehydes are absorbed in the water abosrbing substance 6. Furthermore, while conventional catalyst such as manganese oxidation catalyst, platinum or the like does not react on various noxious constituents and odor constituents until a high temperature of at least 300 deg.C is reached, the water absorbing substance 6 effectively absorbs said constituents even at lower temperatures.

Title: Magnetic disk device
Inventor: SHIRAIWA KAZUYOSHI
IPC: G11B21/10
Filed: 1987-03-25
Abstract: PURPOSE:To read information on a data surface with respect to the position of a fault even if there is the fault on a servo disk surface by providing a means which does not hold servo signal with respect to the fault position on the servo disk surface as a position signal. CONSTITUTION:When a track position which has been set address with the content of an address register 50, a position setting circuit 51 outputs a signal. A position circuit 53 outputs a signal, when a specified position on a periphery which has been set agrees with the counted content of a counter circuit 52. A gate circuit 54 takes the AND of respective signals of the circuits 51 and 53, and supplies the output to a gate circuit 55. When the output signal of the circuit 54 is active, the circuit 55 cuts off an odd sample signal 56a and an even sample signal 57a, and operates the position pulse of the servo signal 3 not to be peak-held in a peak holding circuit group 66. Thus, the circuit group 66 holds a previous state as it is without peak-holding a fault pulse in the signal 63, whereby a position signal is prevented from being disturbed.

Title: Surface displacement measuring instrument
Inventor: YANO TSUTOMU
IPC: G01B11/24
Filed: 1987-03-26
Abstract: PURPOSE:To measure even a small body regardless of the vibration and inclination of the body to be measured by using three optical heads which are <=12mm thick. CONSTITUTION:Three optical displacement gauges 22a-22c which consist of optical head parts and displacement arithmetic parts are arrayed at equal intervals on a line running in the center of the body 20 to be measured and equalized in reference position. Then when position detection sensors 32a and 32b detect the body 20 to be measured, a synchronizing signal is generated 33, and consequently the semiconductor laser of the optical displacement gauges are driven to project light beam arrays from them in parallel, thereby forming light spots 24a-24c on the body 20 to be measured. Their reflected light beams are guided out by the displacement arithmetic parts as outputs 25a-25c relevant to the distances between the body 20 to be measured and the respective optical displacement gauges. Then the outputs 25a and 25c at both ends are added 27 together and voltage-divided 28 by two, and a subtracter 29 finds the difference between this output and the output 25b of the center part. Then a comparator 30 compares a reference signal sent from an operation part 31 with the output of the subtracter 29 to decide and output whether or not the shape of the body 20 to be measured is within specific displacement.

Filed: 1989-03-24
Abstract: PURPOSE:To perform a stable sheet folding and its stacking accurately without being affected by environmental conditions attending on printing operation by reciprocating a sheet pressing roller and used with both functions of sheet folding operation and its stacking operation jointly. CONSTITUTION:A sheet 22 goes down and comes into contact with a paper sensor 14, operating a sheet pressing roller 6 in a B direction. This sheet pressing roller 6 travels as pressing the sheet 22 onto a mount 5 and, after it once stops at a right and, a sense of its travel is changed to a roller B direction. When being turned over, the sheet pressing roller 6 catches a sheet folding position before printing, folding the sheet 22, and afterward it moves in a B' direction likewise as pressing the sheet 22 onto the sheet mount 5, thus its operation at the right of the sheet mount 5 is completed. Even in regard to the left, the same operation quite as the right is performed, thus the sheet 22 is stacked on the sheet mount by continuing this operation.

Title: Weighing machine
Inventor: NAGAYAMA MASAHITO
IPC: G01G21/24
Filed: 1982-04-30
Abstract: PURPOSE:To obtain a weighing machine which reduces a deviation error caused by a position of a weighed article placed on a scale and which can be made small-sized, by providing beams strained by a load and a strain gage delivering an electric signal which changes linearly according to the amount of a strain. CONSTITUTION:The load of an article to be weighed which is placed on a scale 9 is transmitted from the scale 9 to a movable-side stay 7 via a load receiving board 8, moving the stay 7 downward slightly. An upper beam 4 and a lower beam 5 follow this movement of the stay 7 and are bent downward around a fixed-side stay 3 as a supporting point. Since strains are caused in horizontal pieces 4a-5b by the displacement of the beams 4 and 5, electric signals are obtained from strain gages 6a and 6b stuck on the horizontal pieces 5a and 5b of the lower beam 5, respectively. The voltages of these signals have a linear relationship with the amount of the strains and change also linearly in relation to the load. Thus, the weight of the article is transduced exactly into a voltage, and a weighed value is indicated by an indicating element via a circuit.
