Title: Floating magnetic head
Inventor: YAMADA TADAHARU
IPC: G11B5/60
Filed: 1988-08-29
Abstract: PURPOSE:To prevent magnetic short-circuit even if a ferrite-made core and a ferrite-made slider are brought into contact with each other due to any cause by adopting a nonmagnetic substance to a part of the slider at least in proximity to the core. CONSTITUTION:The part of the slider 10 close to a core 20 is a nonmagnetic material. There are some means to make the ferrite nonmagnetic, and for example, the nonmagnetic ferrite is obtained by controlling the atmosphere, temperature and impurity in the case of sintering the ferrite. Or nonmagnetization is attained by applying heat treatment to the slider 10 under a specific atmosphere. Thus, even if the core 20 and the slider 10 are directly brought into contact with each other due to any cause, the magnetic short-circuit is prevented.

Title: Electronic copy device
Inventor: USHIRO SHIGEAKI
IPC: H04N1/19
Filed: 1987-08-26
Abstract: PURPOSE:To obtain a uniform and clear copy for a whole screen through the use of a general and cheap lens by providing a correction means for correcting recording unevenness which occurs between the center part and the peripheral part of the copy, and which occurs due to deterioration in the light quantity of the periphery of a lens. CONSTITUTION:A second cylindrical lens 16, a scan mirror 17 and an ND filter 19 are arranged on the optical axis of a halogen lamp 10. The ND filter is generated in such a way that it gradually becomes thin from the center part to the peripheral part with respect to a vertical direction, and it is considered to transmit light beams much more in the peripheral part than the center part. Since the ND filter 19 adjusts the light quantity of a slit light illuminating the surfaces on the right and left sides of a blackboard becomes much more than the light quantity illuminating the center part, the luminance of an image which a line sensor 40 image-formes becomes always constant.

Filed: 1981-12-24
Abstract: PURPOSE:To attain fail-safe output for a signal processor, by keeping either one level of a binary value of an output signal of a decision circuit even if a processing circuit is failed. CONSTITUTION:A logical circuit 18 of decision circuits 12a-12n goes to +V for a period t1 by a monitor signal from a monitor signal generating circuit 5, and to zero for other period t2. Further, if an output signal keeps +V due to a failure of the processing circuit 1, an output signal of each logical circuit 18 keeps zero, and an output signal of the processing circuit 1 keeps zero, then each logical circuit 17 is not oscillated, allowing the output signal of each logical circuit 18 to keep zero. Thus, the continuity of zero of the output signal of the logical circuit 18 over a long period as a period t3 of the monitor signal or over is used for a sensing signal of a sensor such as the presence of train at a controller of the next stage, and the output signal is in the state of fail-safe.

Title: Band pass filter for variable band width
Inventor: UETAKE TATSUYA
IPC: H03H9/54
Filed: 1987-08-27
Abstract: PURPOSE:To cause the amplitude transmitting quantity of a passing area to be constant by using a variable capacity diode and a piezoelectric element and connecting a gain or an attenuating quantity variable means to a jamin type filter which can control a band width with an electric signal. CONSTITUTION:When a signal is added to an input terminal 20, to a jamin filter output terminal 22, a signal to pass through the band width, which is mainly determined by the electric circuit equivalent constant of a crystal vibrator 2 and the capacity value of a variable capacity diodes 9 and 10, is appeared. Here, the capacity is changed by changing an impressing voltage to the variable capacity diodes 9 and 10 and the band width of a BPF(band pass filter) can be changed by the operation. Since the band width is added to a high input impedance amplifier and suitably amplified, a desired signal is obtained from an output terminal 21 through a resonating circuit and an impedance converting circuit which is composed of a capacitor 6 and a transformer 7 with intermediate tap. Thus, the amplitude transmitting quantity of the passing area can be made constant.

Abstract: PURPOSE:To inhibit the dispersion of a silicide resistance value, and to display an effect on a resistor, to which accuracy is required particularly, by forming a silicide only on the top face of a polycrystalline silicon film. CONSTITUTION:The resist 4 of a layer insulating oxide film 3a is formed and patterned, and the layer insulating oxide film 3a in a region to be silicide-formed is removed while using the resist 4 as a mask.

Consequently, a silicide such as titanium silicide 5 is formed only to the exposed section. A layer insulating oxide film 3b, an opening for a contact, a barrier metal 6 and one-layer aluminum wiring 7 are shaped. Accordingly, the silicide is not formed on the side faces of the polycrystalline silicon film, thus inhibiting the dispersion of the resistance value of the silicide.

Abstract: PURPOSE:To prevent the occurrence of step-shaped distortion at the slanting line portion by synchronizing a vertical synchronizing signal with the head position of the output data from a field memory at the time of still display and forming a scanning line by the same signal at the same position. CONSTITUTION:An image signal Sv is alternately written through a switch circuit 16c in field memories 16a and 16b. The signal, which is written just before, can be obtained from other written memories 16b and 16a as a field double speed image signal Sv*. The picture, in which the field frequency is set to double, is interlacedly displayed. On the other hand, at the time of the still diaplay, memories 16b and 16a are maintained in the write condition and in the read condition respectively and a signal Sv* becomes the F1 field image signal only. As the vertical synchronizing signal, a clear signal RCLR caused at the timing of the head position of the output data from a memory 16a is supplied. Consequently, the scanning line of respective fields is formed at the same position.
