Title: Pendulum type oscillation damper
Inventor: SEDO KAZUTO
IPC: G05D19/00
Filed: 1986-11-12
Abstract: PURPOSE:To always maintain a good damping effect even if the characteristics frequency of a damping object or on exciting frequency is changed in a certain range, by adjusting the lever ratio of a pendulum to the antiresonance point of the damping object to the exciting frequency. CONSTITUTION:If the lever ratio of a pendulum 2 is changed by a variable mechanism, the frequency at the antiresonance point of a damping object 1 is changed. Though the phases of the damping object 1 and a supporting structure 3 are changed at a resonance point and the antiresonance point, the damping object 1 and the supporting structure 3 have natural characteristics that they have 90 deg. phase difference at the antiresonance point. Consequently, the phase difference between the damping object 1 and the supporting structure 3 is detected and the variable mechanism is operated by a control means to adjust the level ratio of the pendulum 2 so that said phase difference is 90 deg., thereby always obtaining a good damping effect even in case of the variation of the characteristic frequency of the damping object 1 or the exciting frequency.

Title: Liquid crystal display device
Inventor: TANNO JUNJI
IPC: G02B1/111
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To make obtainable a high contrast and excellent display quality by forming a reflection preventing film under a light alignment layer in at least a part among light reflecting material layers (such as electrodes) where a polarization direction of light is made different due to reflection. SOLUTION: In the manufacture of the liquid crystal display device, material layers for alignment layers 20, 25 are formed as upper layers above pixel electrodes 18 and counter electrodes 14. Subsequently, when the material layers are irradiated with light, a part of the light is reflected by the electrodes 14, 18 or the like after irradiation of material layers to again irradiate the material layers. In this case, when reflection occurs at tapered parts formed in the periphery of the electrodes 14, 18, it often happens that light polarized beforehand in a specified direction become polarized in other directions due to the reflection. Such kind of reflection disturbs alignment and generates alignment defects. Thus, a reflection preventing film 10 is formed on the upper surfaces of the pixel electrodes 8 and the counter electrodes 14 so as to cover them respectively.

Title: Air conditioner
Inventor: KINOSHITA HIROSHI
IPC: F25B1/00
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To suppress a decrease of cooling capacity while lowering an input current value of an electrically-driven motor in an air conditioner in which a rotational speed of a compressor driven by the motor is controlled by an inverter. SOLUTION: When an input current value In of an electrically-driven motor 11 becomes larger tan a predetermined set value Iset1, it is controlled so as to lower air supply amount of a blower 3. Thus, a low pressure of a refrigerating cycle apparatus is lowered, and a load torque of a compressor is reduced. As a result, even when the value In is lowered, a rotational speed of the compressor can be maintained without lowering it, and hence a decrease of cooling capacity of the apparatus can be suppressed.

Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent toner from dropping and a photoreceptor drum from being damaged because of pressure applied to a scooping sheet when recovered toner becomes much in a cleaning device. SOLUTION: An auxiliary scooping sheet 15 is provided on the just downstream side from a main scooping sheet 14 in the rotating direction of the photoreceptor drum 1. The abutting force of the sheet 15 on the sheet 14 is made weak or the abutting angle of the sheet 15 on the sheet 14 is made to lie. Since the pressure of discharged toner is not applied to the sheet 14, the damage of the drum 1 and the dropping of the toner are prevented. Since the abutting force of the sheet 15 is weak or the abutting angle thereof is made to lie, the damage or the dropping is not caused even when the pressure of the discharged toner is applied. The abutting force of the sheet 15 is weak, so that backflow somewhat occurs, but it is prevented by the sheet 14.
