Title: Output voltage correcting circuit for amplifier
Inventor: YAMANAKA TOSHIHIRO
IPC: H03F1/30
Filed: 1985-10-11
Abstract: PURPOSE:To maintain DC level of output signals or level of low frequency at a specified value by calculating the difference between output signals of positive polarity and output signals of negative polarity and negative feeding back to an amplifier to make calculated difference zero. CONSTITUTION:A difference amplifier 1 consists of an amplifier A, resistors Rf1, Rf2 and a capacitor Cf, and a negative feedback circuit 2 consists of a transistor TR3. A differential amplifier 3 consists of transistors TR1, TR2, resistors Rc1, Rc2 and a constant current power source CC. By such constitution, the difference between output signals VOUT+ of positive polarity and output signals VOUT- of negative polarity is calculated using the difference amplifier 1, and DC bias voltage of the differential amplifier 3 is controlled through the negative feedback circuit 2 to make the difference zero. Thereby, DC level or low frequency level of output signals VOUT+ of positive polarity and output signals VOUT- of negative polarity can be negative feedback controlled to zero level. Accordingly, the capacity of the capacitor C used in the differential amplifier 1 can be made small.

Title: Air conditioner
Inventor: OKAMURA AKINOBU
IPC: F24F13/20
Filed: 1991-09-06
Abstract: PURPOSE:To suppress the temperature rise of an electric component such as a heater by so driving a motor as to close a blow-off port by a wind direction plate after a predetermined time at the time of stopping an operation. CONSTITUTION:When an operator stops an operation in an operation control unit or a preset operating time is elapsed, a controller turns OFF the operation of a compressor and turns OFF an indoor fan 10. That is, a room cooling or heating operation is stopped. At the time of stopping the operation, the controller drives a wind direction plate motor, and rotates upward and downward wind direction plates 12, 13 from a horizontal blow-off position to a position for closing a blow-off port. In this case, the port is closed after hot air is discharged from an indoor unit 3 by delaying the operations of the plates 12, 13 for an arbitrary time from the stop of the operation. Accordingly, the hot air is not stored in the unit 3. Thus, the temperature rise of an electric component such as a heater 9 can be suppressed.

Filed: 1990-08-29
Abstract: PURPOSE: To make it possible to form a semiconductor layer to an arbitrary thickness and to form layers covering column electrodes and blocks on a flat surface by using a photosensitive material of a negative type and executing the photosensitive material after forming laminates. CONSTITUTION: A negative type photosensitive material 22 is applied by a spin coater at nearly the same height as that of the laminates on a base having the lines of the laminates. The photosensitive material 22 is spread by centrifugal force and is irradiated with light after drying. In such a case, polyimide is irradiated with UV rays via the glass base 20. The electrodes 12 and 20 play the role of an opaque mask. Since the polyimide 22 is the negative type, only the region exposed to UV rays are crosslinked. The masked region is removed by using a removing agent. As a result, the intermediate surface is flat and, therefore, disconnection is prevented.

Filed: 1991-09-09
Abstract: PURPOSE:To read out image data from an original carried at an always stable speed by controlling an original feeder to feed an original to an original reading position only at the time of judging that a storage means has storage capacity necessary for image processing. CONSTITUTION:A PCU 81 controls the original feeding operation of an automatic document feeder(ADF), judges whether an original is set up in an original tray of the ADF or not, and when the original is set up, advances a program to the succeeding step. Then the data capacity DO of a main memory 82a which is necessary for image processing based upon respective set up and detected conditions such as a scale, paper size and original size is forecasted. The residual MS of the memory capacity of the memory 82a which is transmitted to an ICU 82 is compared with the capacity DO, and only when MS >DO is formed, the PCU 81 allows the ADF to execute original carrying operation. Consequently the image data of the original carried at an always stabilized speed can be read out at the original reading position.

Abstract: PROBLEM TO BE SOLVED: To make switchable a vibration suppressing mode without causing a time lag and losing the operating posture of a photographer by providing a system for image pickup with a means inverting action state and non-action state selected by a switching means. SOLUTION: An instant switch 2 is arranged at an optional position on a focusing remote controller 3, for example, in addition to a switch for switching the ON/OFF state of a vibration proof function 1. The switch 2 is arranged for temporarily inverting the ON-state or the OFF-state of the vibration proof function designated by the switch 1 in the midst of photographing. Specially, when the on-state is inverted to the off-state, the vibration proof function can be instantaneously recovered when the off-state becomes the on-state again by minimizing the cut-off time of the energizing the vibration proof optical system. When the vibration proof function is desired to be temporarily set in the off-state, for example, it is temporarily set in the off-state by executing such control that the content of the switch 1 is inverted only while the switch 2 is depressed.  Then, when the depressing of the switch 2 is stopped by holding the vibration proof optical system at a specified position, the vibration proof function is switched to be the on-state.
