Title: Light irradiating device
Inventor: WATANABE YUKIO
IPC: B01J19/12
Filed: 1981-09-25
Abstract: PURPOSE:To obtain a small-sized irradiating device that does not cause overheating of a lamp, by installing a pair of shutters having basal ends pivoted at both sides in front of a lamp and having tips opened outward in a light irradiating device. CONSTITUTION:A pair of double open type shutters 3 having basal ends fixed to rotation axes 5 on both sides in front of a lamp with their tips opening outward and capable of opening and closing in front of the lamp 1. When opened, the basal parts are made nearly parallel to the direction of irradiation and the tip parts are opened outward. When closed, the tips are opposed with slight overlapping. By this way, the device can be made small, and radiated light from the lamp 1 is reflected by the shutters 3 and does not return to the lamp. Thus, overheating of the lamp 1 can be prevented.

IPC: G03G15/01
Filed: 1991-05-27
Abstract: PURPOSE:To detect the quantity of toner highly accurately by eliminating fluctuation caused by the staining of a detection window even in the simple, space- saving structure. CONSTITUTION:Two-components developer composed of carrier and toner is attached onto the developing cylinders 1 of developing units 3Y, 3M, 3C, and 3BK. The developer is carried to the part opposed to a photosensitive drum 5 by rotating a sleeve 8 over a magnet 7. By the rotation of a gondola 2, the developing rollers of their respective developing units sequentially face the photosensitive drum 5 via an opening part 6. Toner moves from the napped carrier which is on the developing cylinder 11 without being in contact with the photosensitive drum, and development is carried out. At this time, the developing units sequentially meet a toner concentration detector 11. Light from a light emitting element 9 is directly projected from the opening part 6a to the part where the carrier on the developing cylinder 1 is lying down without being in contact therewith. The light is relfected by the toner on the developing cylinder 1, and received by a light receiving element 10. Thus, the concentration of the toner on the cylinder 1 is directly detected.

Abstract: PURPOSE:To enable repair and renewal of electrical apparatus, etc. with high reliability by detecting the degree of thermal deterioration in the process of progression of continuous deterioration from the change in the IR absorption spectrum of an insulating material by IR spectrochemical analysis. CONSTITUTION:An epoxy resin is used for a sample and is deteriorated in a thermostatic chamber. The change in the IR absorption spectrum thereof is measured. The absorbancy ratio of 825cm<-1> changing with progression of the deterioration is determined with 1,610cm<-1> absorbance as a reference. Activation energy DELTAE is determined by other method and a conversion time theta is calculated. Here (t) denotes the time for deterioration and T the absolute temp. for deterioration. There is a good correlation between the time theta and the absorbancy ratio and if the time theta is equal, the change in the chemical structural quantity owing to thermal deterioration is equal as well. An insulating coil of an electrical apparatus consisting of the same material as the material of the sample is worked for required time and thereafter the insulator is sampled and the absorbancy ratio at 825cm<-1> is determined from the absorption spectrum, by which the time theta is obtd. and the remaining life of the insulating coil is detected. This method is applicable to an enamel wire film, coil impregnating agent and film material as well.

Title: Power supply and separated power supply information unit
Inventor: OTSUKI NORIYOSHI
IPC: H02J1/00
Filed: 1993-06-23
Abstract: PURPOSE:To prevent failure due to short circuit between the output terminals by providing a power supply generating means, an output switch, a power switch, a connection confirming means, and a switching limiting means. CONSTITUTION:Power generated from a power supply generating means 4 is fed to the body section through an output switch 5. The output switch 5 is operated by a user through a power switch 2. A connection confirming means 1 is activated when the body section is connected with the power supply section. A switching control means 3 controls the output switch 5 depending on the output state of the means 1. When the body section is disconnected from the power supply section and the means 1 is inactive, the switching control means 3 locks the output switch 5 in OFF state and thereby the user can not operate the output switch 5. When the means 1 is active, the user can operate the output switch 5 through the power switch 2. This constitution can prevent the failure due to short circuit between the output terminals 6.

IPC: B23K11/00
Filed: 1987-06-18
Abstract: PURPOSE:To save an expensive inactive gas, by equipping blow-off ports for the inactive gas on electrode parts of electrical welding. CONSTITUTION:A plurality of inactive gas blow-off ports 11, 11, ... are opened circumferentially on back-and-forth positions of electrode parts 1, 1's portions where a case 2 contacts with a cap 3, and their blow-off ports 11, 11 are made to mutually communicate with gas channels 12a which extend diametrically and with gas channels 12b which extend axially. Very small amount of the inactive gas is made to flow from the inactive gas blow-off port 11 at the electrode part 1 at the time of welding so that an inactive gas atmosphere is locally produced. Dry air is made to always flow inside a transparent box which houses the whole in order to maintain low temperature there. Since the inactive gas atmosphere is locally thus produced by the blow-off of the inactive gas from the inactive gas blow-off port 11 at the electrode part 1, the amount of using the inactive gas is decreased.

Abstract: PURPOSE: To prevent insulation breakdown of an insulating film by forming a resistive region having a large area in a semiconductive region and forming a bonding pad and a wiring layer in a portion at a location on the resistive region of the insulating film.  
     CONSTITUTION: The area of a resistive region 13 provided on a semiconductor region 11a is made larger than the area of the conventional region. A bonding pad 16 and a wiring layer 17 are formed in a portion at a location on the resistive region 13 of an insulating film 14. Therefore, the bonding pad 16 and the wiring layer 17 do not cover semiconductor regions 11a and 11b, a separating region 12, and the like. In this constitution, since the potentials of the bonding pad 16, the wiring layer 17, and the resistive region 13 directly beneath thereof become the same, the insulation breadkown of the insulating film 14 due to surge voltages, which are applied to the bonding pad 16, are completely prevented even though the thickness of the intervening insulation film 14 is somewhat thin.
