Abstract: PURPOSE:To ensure the detection of a sheet width, by a method wherein, a travel means is abutted against a recording material to scan the surface of the recording material when a carriage reaches a recording area, and the displacement of the travel member is detected by a displacement detecting means. CONSTITUTION:In a recording area, an electric conduction to a solenoid 9 is carried out to make a permanent magnet 10 resile, whereby a travel member 11 is shifted rightward so that the contact part 11A thereof is abutted against a recording sheet 4. In this condition, since a travel detecting part 11C of the travel member 11 cuts a light path of a photointerrupter 12, a presence of recording paper is judged. Next, with the travel of a carriage 2 a sheet width detecting device 1 scans beyond a crosswise edge of the recording sheet 4. At this time, the travel member 11 is excited by the solenoid 9 to move out of the sheet surface, whereby the travel detecting part 11C opens the light path of the photointerrupter 12, and the completion of the opening operation is confirmed. After that, by reversing the conducting direction to the solenoid 9, the travel member 11 is shifted leftward back to a retracted state, and the carriage is returned to prepare for a next recording.

Abstract: PROBLEM TO BE SOLVED: To prevent images from degrading by avoiding the occurrence of shortage of toner and density becoming lowering, white stlipes, and the like at forming adjacent picture images when toner carried on a toner carrier is allowed to fly selectively. SOLUTION: Between a toner carrier 22 and an opposite electrode 25, high voltage is applied from a high voltage electric source 30 to an opposite electrode 25 for forming an electric field to allow carried toner to fly to the opposite electrode side, and a control electrode 28 is interposed between the toner carrier 22 and the opposite electrode 25 in order to control the flying of toner between the toner carrier 22 and the opposite electrode 25. Toner flying electric potential or no toner flying electric potential is applied during the formation of images via a control electric source 31 to a ring- shaped electrode 27 provided around a gate 29 on which the control electrode 26 is formed and to which toner flies, thus forming images by toner on recording paper carried on the opposite electrode 25.  In this instance, the rotational peripheral speed Vs of the toner carrier 22 is made faster than the carrying speed Vb of recording paper 5, so that even when adjacent dots are formed, shortage of toner can be precluded and further the deterioration of an image quantity due to the lowering of density or the like is prevented.

Title: Switching circuit of high frequency signal
Inventor: WARASHINA MITSUO
IPC: H03K17/76
Filed: 1984-02-01
Abstract: PURPOSE:To eliminate the effect of a circuit at the non-conduction side by impressing the adverse bias voltage to a switching diode at the non-conduction side to secure a satisfactory cut-off state. CONSTITUTION:When changeover switches S1 and S2 are turned to the left TV side, a high frequency signal is transmitted to a TV tuner 4 from a signal input socket 1. At the same time, the negative voltage is impressed to a diode D1 at the radio side from a circuit which supplies the negative voltage to a tuning circuit 6 via resistances R4 and R1. Thus the D1 is set under a satisfactory cut-off state. This eliminates substantially the effects of a capacitor C2, a coaxial cable 2 and a radio block 3 which are connected to the D1 and therefore prevents the attenuation of the TV signal. Thus it is possible to avoid the effect of a circuit at the non-conduction side.

Abstract: PROBLEM TO BE SOLVED: To sufficiently and surely prevent the unexpected discharge of toner at the time other than when the toner is supplied by disposing a locking member capable of locking the relative turning of a container shutter member and a main member and releasing the lock, between the container shutter member and the main member. SOLUTION: The locking member 30 attached to the main member 8 is positioned in the annular gap between the inner periphery of the cylindrical part of the container shutter member 10 and the outer periphery of the cylindrical part of the main member 8. When the locking flange part 34 of the locking member 30 is forced against the energization by elasticity of the restraining piece for locking 28 of the main member 8, to be separated upward from the restraining piece 28 in an axial direction, the locking flange part 34 is moved upward along the notch 60 of the container shutter member 10, so that a locking pawl part 36 is released upward from the notch 29 of the flange 24 of the main member 8.  Consequently, the lock by the locking member 30 is released, the restraining piece for locking 28 of the main member 8 is movable along a slit and the main member 8 and the container shutter member 10 can be relatively turned.

Abstract: PURPOSE:To ensure that the spectral distribution of infrared rays of >=2.5mum long wavelength is approximately equal to that of the sunbeam, by setting a light shielding plate with openings that contains a heat insulating layer and an infrared ray reflecting layer at the front of a lamp lighting tool forming a light source. CONSTITUTION:A substrate 2, a heat insulating layer 3 and an infrared ray reflecting layer 4 are laminated at the front of a storing part 1 where plural light sources are stored. A light shielding plate 6 which contains openings 5 at positions corresponding to each light source within the part 1 is provided with the layer 4 set in opposition to the front side of the part 1. Therefore, only the infrared rays of long wavelengths that are diffused from the positions opposite exactly to the openings 5 can pass through the plate 6. Other infrared rays are reflected and diffused by the layer 4. In such a way, the radiation of infrared rays of long wavelengths is greatly reduced. As a result, the spectral distribution of an artificial solar device is approximate to that of the sunbeam over all wavelength regions.
