Title: Output driver circuit
Inventor: DOI YOSHITSUGU
IPC: H03K4/00
Filed: 1992-06-18
Abstract: PURPOSE:To prevent generation of noise by changing a drive transistor (TR) driving an output terminal stepwise from a cut-off state into a conduction state through the action of a stepwise control voltage generating means so as to prevent a steep change in an output current. CONSTITUTION:A TR 44 is connected between a TR 43 and a ground potential VSS Then the TR 42 is conducted faster than the TR 43. Since a voltage being (power supply voltage-threshold voltage vth) is given to a gate of the TR 43 after a time t2, the TR 43 is turned on. Then a voltage of VSS+Vth is given to a gate of a TR 35 and the TR 35 is turned on after a time t3. Then after the time t3, a voltage level of an output signal S0 reaches the voltage TCC. As a result, the signal S0 outputted from a step control voltage generating circuit 201 is a signal waveform changed stepwise. Since the signal S0. is given to a gate of a driver TR 20, the TR changes from the interrupting state to the conductive state in response to the signal S0, then production of a steep change in the power supply is prevented.

Abstract: PURPOSE:To make it possible to detect deterioration of insulation resistance during operation of a rotary electric machine, by connecting a monitoring power source between a field circuit and the earth, and making operation of insulation resistance of field winding by leak current passing from the field winding to the earth. CONSTITUTION:When voltage is impressed onto a field winding 1 from a DC power source 6, which is built in a field ground relay 5, through a field circuit 4b, a current collector brush 3 and a current collector ring 2 on the negative side, leak current passes to the earth through a field winding insulation resistance 12, and this leak current returns to the DC power source 6 through a leak current detector 8. This is detected by the detector 8 and put into an operation process by a circuit 9 together with a voltage of the DC power source 6 detected by the detection-operation circuit 9, and thereby an insulation resistance 12 of the field winding 1 is sought. Thus obtained value is indicated by an indicating device 10 and compared with a normal alarm setting value by an alarm device 11, and when the value proved to be lower than the setting value, an alarm is issued. It is possible, by doing so, to monitor insulation resistance during operation of a rotary electric machine and prevent the machine from being operated abnormally.

Title: Color picture tube
Inventor: UCHIYAMA MAMORU
IPC: H01J29/07
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To decrease deterioration of image quality due to the light emission of a phosphor caused by part of an electron beam irregularly reflected by a mask frame by means of forming long recessed grooves inside the mask frame in the lengthwise direction of its sidwall part by protruding the sidewall part of the mask frame in the directon of a skirt section of a panel. SOLUTION: When a phosphor screen is scanned more than its effective size and when recessed grooves 29 are formed in a sidewall part 23 of a mask frame, the excess scanned electron beam 16 hits against the inside surface of the sidewall part 23. The excess scanned electron beam 16 hit against the recessed grooves 29 repeats the hits and reflection, and thereafter, part of it is allowed to reach a phosphor screen through an electron beam passing hole 20 of a shadow mask 22, so that the reflected beam quantity reaching the phosphor screen can be reduced. Thus, undesired light emission of the phosphor layer due to the reflected beam is reduced, and the deterioration of image quality such as color purity degradation is decreased. The image deterioration of high luminance image is prevented by applying it to a super-large tube or the like.
