Patent JP-H03296774-A (JP)
Title: Sheet feeding device
Inventor: UEKI YOSHIHARU
IPC: B65H16/10
Filed: 1990-04-16
Abstract: PURPOSE:To feed a sheet in a light load state in the case of feeding and reversely feeding the sheet by providing a rotation control means for rotating the driving mechanism of a rotary shaft on a side where the sheet is drawn out, between 1st and 2nd rotary shafts, in a sheet drawing-out direction. CONSTITUTION:A one-way rotation driving transmitting mechanism 11 is provided between the 1st and the 2nd rotary shafts 53 and 54 and 1st and 2nd driving mechanisms 10 and 95 being the driving mechanisms of the respective shafts 53 and 54. Therefore, the rotation in the direction where the sheet 51 wound around the rotary shaft is drawn out, between the rotation of the 1st mechanism 10 and that of the 2nd mechanism 95, is not transmitted from the driving mechanism 10 to the rotary shaft. When the driving mechanism 10 of the rotary shaft on the side where the sheet 51 is drawn out is driven to be rotated in a sheet drawing-out direction by a rotation control means 90 in the case of feeding or reversely feeding the sheet 51, the back electromotive force is not generated and heavy load is not applied because the mechanism 10 is not in a non-excited state even though rotational force is transmitted to the mechanism 10 from the external by drawing out the sheet. Therefore, the torque of the mechanism 10 for drawing out the sheet 51 is restrained to be small. Thus, the load in the case of feeding and reversely feeding the sheet is made light.

CONSTITUTION:An inner flange 19 is protruded from the middle stage part of the inner wall of a frame 11, and a partition plate 20 is mounted in a stretched manner. An inner flange 28 of an opening 16 is joined with a rib 22 through a seal material 29. An opening 16 is closed by a head cover 1b, and an independent carburetor chamber 30 containing a carburetor 26 is formed between the partition plate 20 and the head cover. The inlet of the carburetor 26 is extended through the partition plate 20, and an opening 15 formed in the upper surface of the frame 11 is covered with an air cleaner element 32. Thus, running air introduced through an air introduction port 21 occasioned by running of a car and exhausted through an air exhaust port 22 passes through the carburetor chamber 30. This constitution prevents the occurrence of a trouble due to hat emitted from an engine.

Title: Data processor, data processing method and storage medium storing program readable by computer
Inventor: KANO ATSUSHI
IPC: G06F21/60
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To limit the read of stored data corresponding to a location to execute the read of the data and to freely construct an environment capable of surely evading a situation that the data are leaked to a third person by collating the location of a device main body storing the data and controlling the read of the data. SOLUTION: When a data read request from a data storage device 101 is generated from a reader 102 through a data controller 103, the data controller 103 requests the judgement of whether or not the location of a main body is within a readable area to a location judgement device 104. In response to it, the location judgement device 104 judges a present place and returns the value of read possibility when it is within a specified area and the value of read impossibility when it is on the outside of the area to the data controller 103. Then, only in the case that the value of the read possibility is returned, the data controller 103 withdraws the data ND in a non-ciphered state from the data storage device 101 and transfers them to the reader 102.

IPC: H01C10/00
Filed: 1988-04-21
Abstract: PURPOSE:To eliminate the distortion of the output of a speaker and to obtain a large output by providing a spring material rotating in cooperation with the rotary shaft of a variable resistor, and providing a temporary stopper for increasing the rotary torque force of the shaft on the way of a disk face on which the spring material slides in contact therewith. CONSTITUTION:A spring material 11 to work in conjunction with the rotation of the rotary shaft 5 of a variable resistor is provided, and a temporary stopper 13 for increasing the rotary torque force of the shaft 5 is provided on the way of a disk 12 on which the material 11 slides in contact. If the variable resistor is turned clockwise lightly from a minimum position toward a maximum position when the output level of a signal source is high, it is stopped at the position of the stopper 13, and sound volume becomes large without distortion. Then, if the variable resistor is rotated by further stronger force from the stopped position when the output of the signal source is low, the sound volume can be increased. Thus, even if the output level of the signal source is high, the output of the speaker is not deformed, and even if the output level is low, a large output can be obtained.
