Title: Image forming device
Inventor: OKUMURA KOJI
IPC: G03G15/22
Filed: 1993-06-28
Abstract: PURPOSE:To provide an image forming device capable of making the magnifications of first and second images with respect to an original equal by reducing the size of the second image compared with the first image, because a paper sheet is slightly t-educed in size by the transfer and fixing of the first image. CONSTITUTION:When the first image is copied on the front of the paper fed from paper feeding paths 48 and 52 at a first magnification, the speed of the rotations of a photosensitive drum 28 is set to a normal once and a zoom lens 26 is set in a normal position. When the second image is copied on the front surface of the paper fed from a transfer path 54 at the same first magnification, the speed of the rotations of the photosensitive drum 28 is set lower and the zoom lens 26 is set to the side of reduction. Therefore, the second image can be reduced regardless of the same magnification.

Title: Stencil printer
Inventor: ONO KATSUMI
IPC: B41L13/04
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To keep a secret without generating a waste of a master in a stencil printer having a drum detachable from a stencil printer body. SOLUTION: A RAM 104 for storing setting of a secret keeping mode is provided at not a body side but a drum 31 side. A main CPU 101 of a controller 100 first judges whether the mode is set to the RAM 104 or not when a print command is input and inhibits a printing operation if the mode is set. Thus, since the setting of the mode in the RAM 104 provided at the drum 31 side is always judged in the state that the mode is set when the drum is replaced, even if an unengraved maser is not mounted when the drum is replaced, its confidentiality can be sufficiently kept, and it can allow both prevention of a waste of the unengraved master and keeping of the secret to be compatible.

Title: Camera operation controlling device
Inventor: WAKABAYASHI HIROSHI
IPC: G03B3/00
Filed: 1988-06-24
Abstract: PURPOSE:To prevent defocused picture photographing by inhibiting the manual focal point adjustment of a photographing lens when a focus lock is maintained. CONSTITUTION:The focus lock maintaining means 105 operates with the operation of a focus lock maintaining operation member 104, and even when the preliminary operation of a release operating member 102 is released and even when the preliminary operation is carried out again after the release, the focusing by a focus lock means 103 is continually carried out. An inhibiting means 106 inhibits the manual focal point adjustment of the photographing lens when the focus lock is maintained. Therefore, when the photographing is requested to a third person after carrying out the focus lock operation, the photographing lens position is not changed even when the third person touches the focal point adjusting operation member by mistake. Thus, the photographing of the defocused picture is inhibited.

Title: Dust filter choke display device for fan forced heater
Inventor: KASAHARA AKIHIKO
IPC: F23N5/02
Filed: 1989-06-20
Abstract: PURPOSE:To prevent erroneous display of chocking of a dust filter by a method wherein, during the lapse of a given time starting from a time when a combustion device starts combustion and a blower starts blast, a signal from a temperature detecting device is brought into an OFF-state. CONSTITUTION:When blast is started in a way that a combustion device 5 starts combustion and a blower 1 starts blast, detection of temperature is started by a high temperature detecting device 3. Simultaneously, a timer device 7 starts to count a time, and no signal from the temperature detecting device 3 is inputted to a control device 6 until the timer device 7 counts a given time. After the lapse of a given time, a signal from the temperature detecting device 3 is inputted by the control device 6, and choke display is effected on a display device 4. Since, as noted above, no display is effected on the display device 4 until a given time elapses, erroneous display of choke of a dust filter 2 is prevented from occurring.

Filed: 1989-06-19
Abstract: PURPOSE:To design an LSI and VLSI composed of a plurality of elements, and to contribute to the design of an analog element particularly by inhibiting mutual intervention between the two elements. CONSTITUTION:The drain 2, source 3 and gate 4 of a first MESFET are formed onto a GaAs substrate 1, and the source 5, drain 6 and gate 7 of a second MESFET are shaped.

Title: Insulation deterioration judging method for three-phase power cable
Inventor: YAMAGUCHI SATORU
IPC: G01R31/12
Filed: 1991-05-31
Abstract: PURPOSE:To detect deterioration of a insulator in a hot line including a latent water tree not detected in a cable in the dry state by judging insulation deterioration through measurement of a direct current component in a charging current flowing through a grounding conductor of a power cable in the hot line state and a zero phase current of a three-phase cable. CONSTITUTION:A switch for short-circuit 8 is turned off, and a charging current is made to flow through a measuring device 6. When a surge current arrives during measurement, a safety arrangement 7 is turned on so as to protect the measuring device 6. By this circuit, a direct current component in the charging current, higher harmonics and a high frequency component of a zero-phase current are measured for 12 cables of a cable to be tested 3. When neither of the high frequency component not less than 0.1MHz nor the higher harmonics component fifth or more is detected, it is judged as no insulation deterioration for the power cable 3. By this, even in the cable in the dry state, presence of a latent water tree, that is, insulation deterioration can be surely detected.
