Title: Digital-to-analogue converter
Inventor: HAIKAWA YUKIHIKO
IPC: H03M1/10
Filed: 1980-12-15
Abstract: PURPOSE:To convert n-bit data to an analogue signal with a high precision, by using two D/A converters consisting of a number of bits lower than n. CONSTITUTION:When n-bit data is inputted to a terminal 11, upper l-bit data is not only converted to an analogue signal corresponding to l-bit data by an l-bit D/A converter 5 but also supplied to a memory 6. When l-bit data is inputted to the memory 6, the memory 6 outputs error data corresponding to this data to an operator 7. Meanwhile, (n-l)-bit data inputted to the terminal 11 is inputted to the operator 7 and is added to or subtracted from error data outputted from the memory 6 by the operator 7. As the result, (n-l+1)-bit data where the error of the converter 5 is corrected is outputted from the operator 7. This data is converted to an analogue signal by a D/A converter 8. An analogue signal obtained by synthesizing outputs of converters 5 and 8 is outputted from a terminal 14.

IPC: G11C7/00
Filed: 1983-09-28
Abstract: PURPOSE:To attain a logically precise operation by connecting an exclusive OR circuit between a control circuit and a transfer circuit, and confirming the end of data transfer of one step to send a control signal to a succeeding step. CONSTITUTION:At the time of shift-in, control circuits 5, 6 are actuated and a transfer circuit 10 shifts data by one step by a transfer command signal 13. Since the values before and after the transfer circuit 10 are made equal after completing the shift, the output of the exclusive logical circuit 19 is turned to logical ''0'', a control signal 16 is actuated to shift the control operation to the succeeding step. The operation after the succeeding step and that of the shift-out time are similarly executed and no control signal is sent to the succeeding control circuit unless the end of data transfer of one step is confirmed. If plural strings of data transfer parts exist, the OR of exclusive ORs of respective strings is found out to obtain the output of the exclusive OR circuit.

IPC: F24F13/32
Filed: 1988-07-18
Abstract: PURPOSE:To obtain an integral type air conditioner embedded in a ceiling, whose installation place is less restricted by a space, by horizontally disposing a cooling chamber and a heat radiating chamber within a casing, providing inlet and outlet ports on the lower surface of the casing and an exhaust port on the side surface or upper surface of the casing and further providing a damper which changes over outlet air to the outlet port side or to the exhaust port side. CONSTITUTION:When a fan motor 5 is operated, indoor air is sucked in through each of inlet ports 23 and 33 to pass through an evaporator 21 or a condenser 31, respectively, and is cooled or heated. Outlet air C cooled in a cooling chamber 2 is discharged out of an exhaust port 25 to the external side through an exhaust duct 13, while outlet air W heated in a heat radiating chamber 3 is blown out of an outlet port 34 into the interior of a room to heat the inside of the room. Thus, the constitution of a refrigerating cycle can be simplified, and moreover installation is possible in a narrow space such as one between a ceiling and a floor above the stairs without protruding out of the ceiling. Accordingly, an installation place is not restricted by a space, and electric power required for an operation can also be saved.

Title: Lens driving mechanism, photographing lens device and camera
Inventor: YOSHIDA SETSUO
IPC: G02B7/04
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To restrain vibration and noise and to improve performance by providing a damping member at a part of a cam surface for performing focusing operation. SOLUTION: When a driving motor 31 is actuated and a cam 30 is rotated counterclockwise, the cam surface consisting of the rubber plate 35 of the cam 30 presses a cam follower 29, which follows and moves. When the motor 31 is reversely rotated and the cam 30 is rotated clockwise, the cam surface consisting of the rubber plate 36 of the cam 30 comes in contact with the cam follower 29 and the pressuring force of the cam 30 is reduced. Thus, the cam 30 comes in contact with the cam follower 29 through the rubber plates 35 and 36 except the cam surface of the cam 30, so that the cam 30 and the cam follower 29 are scarcely vibrated when the cam 30 is rotated at high speed or even when the cam 30 is reversely rotated suddenly.  When the cam 30 is at a reference position, the cam 30 comes in contact with the cam follower 29 without through the rubber plates 35 and 36, so that the position of an internal barrel 25, that is, a lens group 24 is accurately set and the performance is improved.
