Abstract: PURPOSE:To increase the resolution of a detected temperature, by selecting the external size suitably and making the temperature characteristics of the fundamental wave and the secondary harmonic remarkably different, in a 2-mode simultaneous energizing quartz oscillator in which the fundamental wave and the secondary harmonic are energized at the same time. CONSTITUTION:The fundamental wave oscillating frequency f1, the secondary harmonic oscillating frequency f2 and the torsional mode resonant frequency are plotted in figure, when the length (l), width W are taken constant and the thickness (t) is changed out of the external size of a 2-mode simultaneous energizing DMR quartz oscillator 7, where a curve 8a shows the fundamental wave of a bending oscillation, a curve 8b shows the secondary harmonic, and the resonant frequency of the bending oscillation is not changed even with the thickness to be changed. On the other hand, curves 9a, 9b show the resonant frequency of the fundamental wave and the secondary harmonic of the torsional oscillation, and the secondary harmonic is about twice the fundamental wave. Thus, the size is suitably selected in this oscillator 7 and the temperature characteristics for the fundamental and secondary harmonic is made different remarkably, allowing to increase the resolution of the detected temperature.

Abstract: PURPOSE:To enable enough and necessary protection without increasing an element formation area by using a protecting circuit accompanying an unused input/output pad for protection between power supply voltage ends. CONSTITUTION:A transistor TrT1 and a transistor T2 are formed in a dead space in an area near an input/output pad 1 and TrT3 and T4 are formed in a dead space in an area near a pad 2. According to this constitution, when a static electricity is applied between the pad 1 and VCC, TrT1 turns 'on' and an inside circuit is thereby protected; and when a static electricity is applied between the pad and VSS, TrT2 turns 'on' and the inside circuit is thereby protected. When a static electricity is applied between VCC and VSS, the inside circuit is protected since TrT3 and T4 turn 'on' which are not connected with the inside circuit and the pad. As for protection operation in the process, it is enough only if either TrT3 or T4 turns 'on'; therefore, sure protection operation can be expected.

Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent a seal glass and optical parts in an optical box from being stained and obtain a good print image quality at all times without frequent maintenance by controlling an air flow in an image-forming apparatus. SOLUTION: An air flow (shown by an arrow) formed between a supply air opening 48A of a supply air duct 48 and an exhaust air opening 50A of an exhaust air duct 50 generates a vortex or negative pressure between a seal glass 36 and a photosensitive body 10. The air is sucked in front of the seal glass 36 by setting an inflow opening 44A of an inflow duct 44 to which the air can flow in, whereby generation of the vortex or negative pressure is prevented. A flow of the air is accordingly prevented from being formed in front of the seal glass 36. Stain is prevented from adhering to the seal glass 36. Even when a projection opening 38 is open, no negative pressure is generated in an optical scanning apparatus and therefore the outside air including dust is prevented from invading the optical scanning apparatus.
