Title: Bipolar level shift circuit
Inventor: HASHIMOTO MASAMI
IPC: H03K19/0944
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To obtain a level shift circuit that converts both positive and negative levels of a low level system into those of a high level system simultaneously with low power consumption by connecting an output terminal of a low level system signal drive circuit having a diode to a high level system latch circuit consisting of inverter circuits in cross connection. SOLUTION: A low level system signal drive circuit 30 employs power supplies whose voltages are -VSS1 and +VDD1 and has diodes 32, 34 at its output terminal. A high level system latch circuit employs power supplies whose voltages are -VSS2 and +VDD2 and has inverter circuits in cross connection. Then a signal from the low level system signal drive circuit 30 is fed directly to the high level system latch circuit. Thus, the high level system latch circuit is inverted by the signal from the low level system signal drive circuit 30. Furthermore, since the diodes 32, 34 are provided to the low level system signal drive circuit 30, a reverse flow from the power supplies of the high level system to the power supplies of the low level system is prevented. As a result, bipolar level conversion is attained with low power consumption without a leakage current.

Abstract: PURPOSE:To prevent the generation of leak of a junction at the isolation end of an element isolating film at the time of forming a silicide film on a diffusion layer, by a method wherein, after a trench is formed on a silicon substrate, an element isolating part to be bonded with an impurity diffusion layer is formed by burying SiO2 in the trench. CONSTITUTION:When a silicide film 6 is formed, in the self-alignment manner, on at least an impurity diffusion layer 3 on a silicon substrate 1, an element isolation trench 1a is formed on the silicon substrate 1. An element isolating part 20 is formed by burying silicon oxide in the trench 1a. A gate oxide film 2a is formed on the surface of a silicon substrate 1 by thermal oxidation. Then impurity is implanted in the silicon substrate 1 via the gate oxide film 2a, thereby forming an impurity diffusion layer 3 around the element isolating part 20. after the gate oxide film 2a is eliminated so as to expose the surface of the impurity diffusion layer 3, a silicide film 6 is selectively formed on the exposed surface of the impurity diffusion layer 3. For example, the above silicide film 6 is a TiSi2 film formed by laminating Ti films and then performing heat treatment.

Abstract: PURPOSE:To effectively absorb the vibration transmitted to a yoke frame by dry friction produced at contact points between a plate member and tubular bodies by a constitution wherein both ends of the plate member bent in the form of the yoke frame are protruded in the yoke frame and yet the tubular bodies are arranged so as to contact with protruded parts and the inner wall of the yoke frame. CONSTITUTION:Both the ends of a plate member is protruded in the mechanical construction 1 formed in a yoke frame by bending said plate member so as to form the protruded parts 2 and yet tubular bodies 4 are arranged so as to contact with both the protruded parts 2 and the inner wall of the yoke frame. Due to the constitution as mentioned above, when vibration is transmitted through the bed or the like of a machine to the mechanical construction 1, the vibration is transmitted through the protruded parts 2 to the tubular bodies 4. At that time, dry friction due to minute slides is generated at the contact surfaces between the protruded parts 2 and the tubular bodies 4 and between the inner wall of the yoke frame and the tubular bodies, resulting in effectively absorbing vibrational energy.

Abstract: PURPOSE:To continuously obtain high-softening pitch suitable for carbon fiber production, by dispersing, in the form of fine oil droplets, heavy oil or pitch in a gas stream to effect contact between said droplets and e.g. an inert gas. CONSTITUTION:For example, heavy oil or pitch is dripped on a revolving disc structure to scatter said oil or pitch out of the periphery in the direction virtually rectangular to the revolving shaft, taking advantage of the centrifugal force of said disc structure, thus dispersing the heavy oil or pitch in the form of fine oil droplets in a gas stream. Thence, the oil droplets dispersed is brought into contact with the inert gas or superheated vapor followed by treatment on heating to 350-500 deg.C under reduced or normal pressure to obtain the objective pitch in a continuous manner.

SOLUTION: A CCD line sensor 12 is arranged via a photographic lens 14 for picking up the images of upside face (b) and original surface (a) of book original B placed on a platen 6. The images of original surface (a) and upside face (b) of book original B are guided directly through the photographic lens 14 inside a scanner unit 1 to the CCD line sensor 12. Since the photographic lens 14 is located above the book original B and further outside the original picture of book original B, an image of the book original B as seen from the oblique upside is formed on the CCD line sensor 12. Thus, since the original surface (a) and the upside face (b) are photographed directly, the finder mirror for projecting the upside face (b) of the book original B can be omitted.

Abstract: PURPOSE:To reduce the processing time and to attain miniaturization and light weight by applying a second drive voltage across a parallel connection electrode of optical switches arranged adjacent to each other to change a carrier quantity stored in the optical switch in response to an input picture of the adjacent optical switch and detecting the edge based on the carrier quantity stored in each optical switch. CONSTITUTION:A 2nd drive voltage V2 remains '0' in the lst step and a voltage slightly lower than a switching voltage VS of an optical switch 8 is applied as a lst drive voltage V1. Then in the 2nd step, after the 2nd drive voltage V2 rises up to the switching voltage VS, the lst drive voltage V1 is restored to '0'. Finally, in the 3rd step, the 2nd drive voltage V2 is set to '0' and the lst drive voltage V1 is set to a negative level to apply negative bias. In this state, when the lst drive voltage V1 is arisen to a level slightly lower than the switching voltage VS, only the optical switches 8 of B, D are active and a light is emitted. Thus, the edge of an input picture is detected in this way.
