Title: Image forming device
Inventor: HANEDA SATORU
IPC: G03G15/08
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device capable of setting magnetic particles without causing the alteration and the deterioration of an image forming body by controlling so that toner concentration in a magnetic brush may be a 1st set value in the operation. SOLUTION: The toner concentration in the magnetic brush in the operation when toner left after transfer is recovered and discharged is controlled within 2 to 7% as the 1st set value TC11 lower than the developer concentration to be ordinarily set to 5 to 10% in a developing means. A 2nd set value TC12 is 2% of the lower limit value of the toner concentration, and a 3rd set value TC13 is 7% of the upper limit value of the toner concentration. When the concentration is equal to or under the 2nd set value TC12 (2%), the deterioration of carrier and the alteration of the image forming body are caused due to the adhesion of the magnetic particles to the image forming body when applying bias and the breakdown and toner filming on the image forming body.  When it is equal to or above the 3rd set value TC13, image fogging is caused by the adhesion of the magnetic particles to the image forming body and faulty cleaning.

Abstract: PURPOSE: The inexpensive and highly reliable captioned sensor which comprises constituting a sensor base body by the perovskite type oxide containing Co, Mn, etc. and which stably operates even in the atmosphere of exhaust gas or the like in which oxidative gas and reducing gas co-exist.  
     CONSTITUTION: The oxygen density detecting sensor consists of a sensor base body 10, electrodes 11, which are mounted on body 10, composed of metals such as Pt, Pd, Au, Cr, C, Ni, W and a sintered alumina-made stand 13 to which the sensor body 10 is mounted. This sensor base body 10 is constituted by the perovskite type oxide having chemical formula of ABO 3  and Co or Mn is contained in part or the whole of the B site. As a result of this, the oxygen density detecting sensor exhibits combustion catalyst action and P-type semiconductor characteristic and in oxidative gas it exhibits extremely low resistance. In a reducing gas atmosphere, it causes a considerable resistance increases. Thus, even if it is used in the atmosphere of the exhaust gas in which oxidative gas and reducing gas co-exist, its operation will not become unstable near the equivalent point.

Title: Electronic camera
Inventor: HINO HIROMASA
IPC: G03B7/16
Filed: 1986-02-26
Abstract: PURPOSE:To automate rear-light photography and to eliminate an error in the photography by comparing the levels of the output signals of the 1st and the 2nd photosensors provided almost in front of and above a camera body with each other and generating a rear-light detection signal when the former is a specific value larger than the latter. CONSTITUTION:The camera receives light in a normal lighting state more intensely from in front of than from above, so the level of the output signal of the 2nd photosensor 42 provided above is higher than the level of the output signal of the 1st photosensor 40 provided in the front and a comparator, therefore, generates no rear-light detection signal. In a rear-light state, on the other hand, the light from the front is intenser than the light from above (ambient light) and then the output signal of the 1st photosensor 40 becomes higher in level than the output signal of the 2nd photosensor 42, so that the comparator 44 generates the rear-light detection signal. Intense electronic flash light is emitted in response to the rear-light detection signal and a white balance adjustment and a stop adjustment are made correspondingly, so that a natural color photograph or image is obtained even by rear-light photography.

IPC: F16B4/00
Filed: 1979-04-06
Abstract: PURPOSE: To efficiently and continously assemble a bridged cylindrical ring in a unit machine, by once triangularly deforming the outer cylindrical shell of a uniform-velocity joint or the likeof an automobile, fitting the outer shell to a trifurcated  bridge and then restoring the original shape of the cylindrical member.  
     CONSTITUTION: In a set state, an outer cylindrical shell 3 is pressed at between its projecting parts 5 by a pressing punch 17 so that the outer shell is deformed as a triangle. An air cylinder 39 is then moved down to insert a trifurcated bridge 4 in the triangular outer shell 3 concentrically therewith. Another cylinder 25 is  moved down to separate sliders 20, 21 from the pressing punch 17. An outward force is applied to the punch 17 by a return spring 19 so that the punch is separated from the outer shell 3. At the same time, a restoring punch 18 is pushed inward by the slider 21 against the return spring 19 to contract the projecting parts 5 inward and restore the original shape of the outer shell 3. The projecting parts 5 are fitted  in the fitting holes 6 of a joint. This results in providing the uniform-velocity joint  as a bridged cylindrical ring.

Abstract: PURPOSE:To control the generation of flaws in a film deposited on a substrate by forming many closely spaced recessed grooves on the surface of a discharge electrode opposed to another discharge electrode provided with a substrate and making the deposited film difficult to peel. CONSTITUTION:A drum-shaped substrate 2 is freely rotatably provided in a cylindrical vacuum chamber 1 as one discharge electrode, and two halved cylindrical discharge electrodes 3 are fixed on both sides of the substrate 2 with a space 4 in between.

A grooved plate 8, on which many V-shaped recessed grooves 6 are formed at intervals of <=5mm is fixed to the circular surface. The raw gas is decomposed by plasma in the space 4 to deposit a thin film on the substrate 2, hence the film deposited on the surface of the grooved plate 8 is thinned and flaked, and the flakes are hardly scattered. The deposition of the flake on the substrate 2 is thus reduced, and a thin film is formed with less flaws.

Title: Current limiter
Inventor: SUZUKI SHIGEMITSU
IPC: H02P3/08
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To decrease the number of the parts of a current limiter by detecting the current flowing through a motor, stopping the flowing of the current larger than a specified current value through the motor and stopping the current supply to the motor when the operating time is longer than the specified time. SOLUTION: The current flowing through a motor 50 is detected by a current detector R. When the detected current is larger than a specified current value, the flowing of this current is stopped by upper-current-limit-value restricting means AMP, HYS, COM, TTL, AND10, AND11,,AND20, AND21 and AND3. When the operating time of the upper-current-limit-value restricting means AMP, HYS, COM, TTL, AND10 and 11, AND20 and 21 and AND3 becomes longer than the specified time, the current supply to the motor 50 is stopped by the current-restricting-time measuring means CPU and TTL. Thus, the number of the parts of the current limiter can be decreased.
