Patent JP-H0378944-A (JP)
Title: Cathode-ray tube
Inventor: MISUMI AKIRA
IPC: H01J29/88
Filed: 1989-08-23
Abstract: PURPOSE:To provide a CRT with a long lifetime by using a vacuum envelope, wherein the inner surface of a glass bulb consisting of alkali glass containing alkali earth metal oxides and/or lead oxides is covered with a thin layer of borosilicated glass. CONSTITUTION:Borosilicated glass layers 1a, 2a in respective specified thicknesses are formed over the internal surface of a base material for alkali glass. A fluorescent screen is formed over the internal surface of a panel 1, and a shadow mask for selection of fluorescent substance is arranged thereon in its position nearer the electron gun. A graphite conductive film is formed over the surface of a funnel 2 and affixed fusion to the panel 1 with a low- melting-point crystallized glass. Thus the internal wall surface of a bulb consisting of alkali glass is covered with borosilicated glass which gives less emission of gas, to reduce the amount of gass emission compared with the condition in which the original internal wall surface of the bulb consisting of alkali glass is exposed, which should prolong the practical lifetime of a resultant CRT.

Title: Bicmos logic circuit
Inventor: OKAMURA HITOSHI
IPC: H03K19/0944
Filed: 1994-09-08
Abstract: PURPOSE: To attain the operation at a lower power supply voltage by limiting a period for operation of a base potential fixing circuit to be a period when an output potential is at a high level so as to avoid the saturation of an output decreasing NPN bipolar transistor(TR) thereby decreasing an output low potential up to a level of GND. CONSTITUTION: A CMOS inverter circuit 14 detecting a potential at an output terminal controls on/off of PMOS 15,17 and an NMOS 20. Thus, the operation of a base potential fixing circuit comprising an NPN bipolar TR 10, and 1st and 2nd resistive elements 18, 19 or the like is stopped when an output potential is at a low level to decrease a base potential to the 2nd NPN bipolar TR 6 to a GND level and even when the output potential is decreased up to the GND level, the saturation of the 2nd NPN bipolar TR 6 is avoided. Thus, an output dynamic range is extended and the operation of the circuit is attained at a lower power supply voltage.

Title: Phase locked oscillation circuit
Inventor: HIRATA MINORU
IPC: H03L7/22
Filed: 1987-08-31
Abstract: PURPOSE:To set output frequencies at arbitrary frequencies, which are not limited to an integral multiple of a first reference signal, by mixing a second reference signal with the output signal of a voltage controlled oscillator, and outputting only a desired band through a voltage control band passing filter. CONSTITUTION:When the respective dividing numbers of a divider 2 and a divider 3 are made variable, in accordance with the division, the output signal of a voltage controlled oscillator 1 is set at an integral multiple of a reference signal I, the controlled output signal is mixed with the signal of a reference signal II at a mixer 6. 'output signal+reference signal II', 'output signal-reference signal II', and other frequency waves are generated to the output of the mixer 6, in such a time, when the control voltage of a voltage control band passing filter 7 is at a feedback voltage VC and is set so as to synchronize with the frequencies of 'output signal+reference signal II', the output passing through the filter 7 becomes the frequencies of 'output signal+ reference signal II' and the other frequencies are eliminated. Thus, the output signal does not limited to the integral multiple of the reference signal I, and it can be set at the arbitrary frequencies.

Title: Driving method for motor
Inventor: MORIMOTO HITOSHI
IPC: H02P6/06
Filed: 1989-08-22
Abstract: PURPOSE:To reduce an error of a detection rotating position due to misalignment of a commutation angle and to prevent a motor from running away by measuring the actual commutation angle of the motor before the motor enters a normal operation and comparing it with a preset value. CONSTITUTION:An essential section is composed of a motor 1, a sensor 2, a sensor I/F 3, a counter 4, a position controller 5, a speed controller 6 and a power controller 7. When a power source of a system is turned ON, a CPU 55 reads the counted value of a phase difference counter 43 and the value of a commutation angle preset by the counted value of a DIP switch 57 before it enters the normal operation of the controller 5. The commutation angle calculated from the value of the counter 43 is compared with the commutation angle read from the switch 57, whether the difference falls within an allowable range or not is judged, and the commutation is controlled. Thus, even if the commutation angle of the motor itself does not match to that set by a driver, it can prevent the motor from running away.
