Title: Image creating device
Inventor: TANIMOTO YASUFUMI
IPC: G03G15/00
Filed: 1986-06-30
Abstract: PURPOSE:To enable use as long as the body itself performing image creation is not out of failure, by furnishing a judging means which is to judge the condition of connected apparatus, and a means which allows continued processing of the apparatus separately if said judging means judges that the apparatus has any failure. CONSTITUTION:A jogger 4, a multi-cassette 2 and an envelope feeder 3 are controlled on the basis of print data given by any external device 50, and thus printing operation is performed. If, in this condition, a failure sensing signal is fed to a control part 51 from a failure sensor 4a in the jogger 4, the control part 51 continues the printing operation with processing by jogger 4 separated. If a failure sensor 2a in said multi-cassette feeder 2 or one 3a in the envelope feeder 3 gives a failure signal, the processing by corresponding device is separated and the printing operation is continued. Accordingly this is serviceable as long as the laser printer 1 itself is not out of order.

Title: Detector of boundary position and angle of edge image
Inventor: IWASAKI JUN
IPC: G01B11/26
Filed: 1985-07-12
Abstract: PURPOSE:To photoelectrically detect the boundary position and inclination of an edge image at the same time by adding, subtracting and dividing the output signals of central and sectorial photosensitive elements. CONSTITUTION:A circular central photosensitive element A0 and sectorial photosensitive elements A1-A4 arranged on a concentric circle constitute a detector and the areas of the elements A0-A4 are made equal to one another. When the boundary of an edge image is positioned on the center of the element A0, the output signal (I1+I2+I3+I4) of adding means C0 is in proportion to the sum of the light regions of the elements A1-A4 and the output signal I0 of amplifying means B0 is in proportion to four times the light regions of the element A0, being equal to the output signal of the adding means C0. Therefore, the output signal of subtracting means D0 becomes equal to zero. That is, by detecting a zero signal, the position of the boundary can be positioned on a center. Since, at the same time, an output signal in direct proportion to an inclination relative to a reference line is obtained from dividing means E1, the inclination can be known by multiplying the half of the sectorial angle of the sectorial element.

Title: Transmission line type antenna
Inventor: TAKAHASHI MASAMI
IPC: H01Q9/30
Filed: 1979-11-28
Abstract: PURPOSE:To avoid the problem of impossible restoration by excessive cut of antenna, by locating frequency adjusting plate and adjusting the frequency with the size of this adjusting plate. CONSTITUTION:Between an antenna element 1 and a ground plate 2, a frequency adjusting plate 6 is in contact with the ground plate 2. This adjusting plate 6 reduces the distance between the element 1 and the ground plate 2 from d1 to d2 to increase the capacity, and the insertion of the adjusting plate 6 reduces the frequency. The frequency adjustment is made by cutting the tip 11 of the plate 6. While cutting the tip 11 of the plate 6, since the center frequency goes higher, the setting to desired frequency can be made through this cut. Since this plate 6 can be replaced even if it is excessively cut, the defect of impossible restoration at the stage of adjustment can be removed.

Title: Selective etching method of oxidized film on wafer
Inventor: NOBE KAZUE
IPC: H01L21/306
Filed: 1991-05-30
Abstract: PURPOSE:To selectively etch an oxidized film on the front surface of a wafer without damaging the film by forming the oxidized films on both surfaces of the wafer and providing a positive resist exposed with patterns from the surface and a positive resist exposed over the entire surface thereon, then providing the rear surface with a positive resist. CONSTITUTION:The front surface of the wafer 1 formed with the oxidized films 2 on both surfaces is coated with the positive resist 3, which is exposed with patterns. The surface of the exposed positive resist 4 is again coated with the positive resist 5 and is subjected to non-pattern exposing. The first positive resist 3 is thereby not exposed and the completely exposed positive resist 6 is formed. The front surface of the wafer having such positive resist 6 as a protective film is attracted to the chuck (not shown in Fig.) of a resist coater and the rear surface of the wafer is coated with the positive resist 7. After the resist is then developed, the oxidized film 2 on the front surface is etched according to the resulted patterns and the resists 3, 7 are removed in the state of allowing the oxidized film 2 to remain on the rear surface.

Title: N:1 backup system for decentralized microcontroller power source
Inventor: TSUJI AKIHIRO
IPC: G06F11/07
Filed: 1981-09-30
Abstract: PURPOSE:To relieve a burden on an operator greatly when a power source is faulty, by monitoring the number of normal power sources and stopping the arithmetic of a controller in case of the fault of the power source in accordance with priority. CONSTITUTION:For example, if one of five power sources has a fault, the arithmetic of only a local controller SLC-4 with low priority is stopped to reduce the current consumption of the system. Then, a transmission controller SLC-5, a device master controller MC, a fuel system controller SLC-1, an air system controller SLC-2, and a water feed system controller SLC-3 which control a control system with high priority are allowed to perform arithmetic continuously. Thus, the number of normal power sources is monitored to allow the controllers to perform control, and as the number of faulty power sources increases, the arithmetic is stopped starting at the controller with the lowest priority. Consequently, automatic control by the controllers is performed.

Title: Optical magnetic recorder/reproducer
Inventor: SANO SHINYA
IPC: G11B11/00
Filed: 1979-11-27
Abstract: PURPOSE:To realize a high-accuracy reproduction through an optical recorder/reproducer, by incorporating the laser beam heating means which heats up the micro region of a magnetic substance, the detecting means of line of magnetic force which detects the change of the residual magnetization of the micro region and the shifting means of the magnetic substance. CONSTITUTION:The micro region spot 7 on the magnetic region is heated up by the laser beam 5 while giving the change of magnetic field based on the recording information through the magnetic head which functions as a detecting means of the line of magnetic force. Then the tape 1 is made to travel to record the information on the track 8. The information thus recorded is traced again by the same device, and thus the micro region recorded is heated up to reduce the residual magnetization. This change of reduction is detected through the magnetic head 4 and then processed through a detection circuit to read out the recorded information. As a result, a recorder/reproducer which can reproduce in a high accuracy the information immediately after recording with no transfer can be obtained through a simple constitution.

Title: Crystal oscillator
Inventor: YAMAZAKI TSUNEO
IPC: H03H9/56
Filed: 1977-12-22
Abstract: PURPOSE:To obtain a crystal oscillator featuring a low resonance frequency by giving the + or -15 deg. rotation to the crystal thin plate of the rectangular Y plate around the Y axis, applying the parallel electric field to the plate surface via the electrode provided on the thin plate surface and thus exciting the flexion vibration. CONSTITUTION:A pair of electrode 5 and 6 are provided on the surface of crystalflexion oscillator 4 composed of the thin plate crystal of under 0.5 mm thick. Now, if the positive and negative voltage is applied to electrode 5 and 6, the electric field inside the crystal is as shown by the arrow in the diagram. Thus, the opposite distortion is caused between the upper and lower surfaces and in the length direction of the crystal plate, then causing the flexion vibration which oscillates in the thickness direction of the crystal plate. The thickness of the crystal plate can be reduced down to about 20 mum through polishing, so the resonance frequency of the oscillator can be reduced down to about one-to-several number or less compared with the conventional value.
