Title: Differential amplifier
Inventor: FUJITA KENJI
IPC: H03F3/45
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To reduce gain at the high frequency region of an input signal of a differential amplifier circuit. SOLUTION: First and second output transistors(TRs) 91, 92 and an output resistive element 93 are connected in series to form a push-pull type output buffer circuit 53, first and second differential output terminals 67, 68 of a differential circuit 52 connect to base terminals of the first and second output TRs 91, 92, and a power output terminal 96 is provided to a connecting midpoint of the first and second TRs 91, 92. A high frequency bypass capacitor interconnects a connection midpoint between the second output TR 92 and the output resistive element 93 for advancing the phase of an emitter level of the second output TR 92.  Even if the frequency of an input signal becomes higher and the phase of a signal of the collector of the second output TR 92 lags behind, the phase of a signal at the emitter of the first output TR 91 becomes nearly in phase with the phase of a signal at the collector of the second output TR 92 for maintain the push-pull operation.

Title: Multi-select water level detector
Inventor: TATEISHI KAZUFUMI
IPC: G01F23/24
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing cost while saving the space by outputting a plurality of input water level signals, one by one, at a constant period in predetermined order and then measuring the water level simultaneously based on these signals through a single circuit. SOLUTION: Electrode rods 11A, 11B, 11C and 11D secured 12 in a water tank 10 measure, respectivelly, the abnormally high water level, the water level when a pump is operating and stopping, and the abnormal low water level. More specifically, an earth rod 11E and the electrode rods 11A, 11B, 11C, 11D are conducted when water is present between them and respective water levels are detected before notifying the presence of water by outputting an on/off signal. An analog multiplexer 13 connected with these electrode rods delivers the output signals from respective electrode rods, one by one, at a constant period in predetermined order to the liquid level circuit 15 for only one circuit. The circuit 15 detects the on/off signal depending on the output signal being delivered one by one.  When the water level is located between the electrode rods 11B and 11C, for example, an on (off) signal is outputted from between the electrode rods 11C, 11D (11A, 11B) and the earth rod 11E. A control section 16 determines the current water level by recognizing individual on/off signals from the circuit 15 totally.

Filed: 1989-12-08
Abstract: PURPOSE:To reduce the deformation and the vibration of a main frame part of a rack base, to obtain exact image information, and to improve the image quality of a display image by constituting a device so that the turning part of the other end part of the main frame part is supported against a stand part through a buffering means. CONSTITUTION:A main frame part 3 is stable since it is supported by the four parts of supporting points A, B, a diagonal driving supporting part C and a damper supporting part D, and also, since a shock which an arm part 3b receives is absorbed by a damper 8, the deformation and the vibration of the main frame part 3 generated at the time of scan operation and at the time of actuation and the shut-off of a diagonal driving means 7 are reduced. Accordingly, the fluctuation of the scan center displacement in the course of scan is reduced, and exact image information by high resolution and high image formation degree can be obtained, therefore, the image quality of a display image is improved. Also, since the main frame part 3 is stable, the difference of a CT image caused by the scan of CW/CCW rotations can be reduced.

Title: Automatically setting method for number of waits
Inventor: KUNIEDA HIROSHI
IPC: G06F13/42
Filed: 1988-12-19
Abstract: PURPOSE:To easily and automatically set the necessary number of waits by allowing the set number of waits to be incremented successively, and registering and setting the number of waits at the time when the external memory of an object can be made access correctly. CONSTITUTION:A check pattern written in advance is read in a memory which can make an access at high speed, and the number of waits is set temporarily to '0'. Subsequently, a prescribed pattern is written in an external memory, and thereafter, this data is read out and whether it coincides with pattern data or not is discriminated. When it does not coincide, the number of waits is brought to increment and the same procedure is repeated again. On the other hand, when the read-out data coincides, the number of waits which is set at present is registered and set as a normal one to a prescribed memory. In such a manner, the number of waits can be set automatically without considering the access speed of the external memory and an input/output interface at the time of designing a system.
