Title: Rotary drum for information recording and reproducing
Inventor: ICHIKAWA RYOICHI
IPC: G11B5/52
Filed: 1989-03-20
Abstract: PURPOSE:To decrease the clearance between a rotary drum and a magnetic tape on the inlet side of the drum and to assure the clearance between the rotary drum and the magnetic tape on the outlet side of the drum by providing a hole for discharging air on the surface of the rotary drum. CONSTITUTION:The air between the rotary drum 1 and the magnetic tape 3 has such a positive pressure as to balance with tape tension. The hole 2 is, therefore, provided on the surface of the drum 1 and the other end is held open to the atm. pressure. Then, the air between the drum 1 and the tape 3 escapes through the hole 2. The area of a flow passage increases and the rapid escape of the air is possible as the clearance h between the drum 1 and the tape 3 is larger. On the other hand, the escape quantity of the air is small and the clearance between the drum 1 and the tape 3 is assured in the region where the h is small. The clearance of the drum 1 and the tape 3, therefore, decreases in the inlet side region 6 of the drum where the h is large. The clearance between the drum 1 and the tape 3 is assured in the outlet side region 7 of the drum where the h is small.

Title: Image forming device
Inventor: MASUKO KAZUHISA
IPC: G03G15/14
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a finger mark, etc., caused by contact with a peeling pawl by discharging electricity only for the top end part of a recording medium with a tooth-shaped discharge member (DTS), so as to peel the top end part from an electrostatic latent image carrier and receiving the top end part, and guiding it to a fixing means side, with a paper guide. SOLUTION: This image forming device is provided with a discharge voltage applying means for attaining the discharge of a region over a corona discharge area, only in the top end part of a paper sheet 6, to peel the top end part from a drum 1, by the tooth-shaped discharge member DTS. The paper guide 5 for receiving the top end part of the paper 6 peeled by the DTS, to guide the paper 6 to a fixing means, by attracting force by the application of a voltage having the same polarity as that of the potential of the drum 1 is disposed on the downstream side in the moving direction of the paper 6, of the DTS. The discharge-voltage-applied DTS starts to discharge the electricity, when the top end of the paper approaches a discharge position and in the paper having the discharge, a charge is removed from the top end.  The voltage-application- stopped DTS stops to discharge the electricity and the end part of the paper is destaticized and received by the paper guide.

Title: Air-fuel ratio controller for internal combustion engine
Inventor: NAGAISHI HATSUO
IPC: F02D41/00
Filed: 1986-03-25
Abstract: PURPOSE:To keep responsiveness and exhaust emission at the time of transition so favorably, by installing a discriminating device discriminating a driven state, which makes the degree of smoothing differ, and a smoothing device smoothing an equilibrium quantity or an under-and-over quantity in an engine suction system holding fuel quantity. CONSTITUTION:A variation in a driving state is operated by an operational device 9, and the driving state that makes the degree of smoothing differ according to this variation is discriminated by a discriminating device 10. In response to this discriminated result, an equilibrium quantity MO or an under-and-over quantity DM in an engine suction system holding fuel quantity is smoothed by a smoothing device 11. In consequence, a signal waveform of the MO and the DM varied as receiving the influence of suction pulsation is made even by smoothing operation at time of steady driving, thus any influence on the suction pulsation is eliminated. Thus, drivability and exhaust emission at the time of transition is favorably keepable.

Title: Power saving device
IPC: G06F1/04
Filed: 1992-03-25
Abstract: PURPOSE:To avoid unnecessary clock supply to a CPU and to reduce the power consumption of the whole of an information processor by stopping the supply of the clock of one device which can be a bus master at the time when the other device is the bus master. CONSTITUTION:When a CPU 2 is the bus master, a DMAC 3 makes a hold request signal HRQ-P31 active for the purpose of using a bus 1 and requests transfer of the bus right to the CPU 2. The CPU 2 makes a hold permission signal BLDA-P21 active at a proper timing and transfers the bus right to the DMAC 3 and is set to the hold state. Since the CPU 2 is in the hold state at this time, unnecessary power is consumed if the clock from a clock signal 24 is supplied. Therefore, a clock signal 23 is masked by a mask signal 25 and an AND gate 26 to prevent a clock signal 24 from being supplied to the CPU 2. Thus, the power consumption is reduced because the unnecessary clock is not supplied.

Abstract: PURPOSE:To attain the forming of a mark sheet less in mis-recognition based on a manually described mark sheet for a control data, by forming the mark sheet with the reader and the recording section of a facsimile device. CONSTITUTION:A mark sheet original 1 is read at a reading section 41 of a facsimile device. The original is discriminated from the read picture signal at a decoding section 42 at first. The signal decoded is converted into a character code and a bar code while collating the signal with the content of an ROM43 and written in a memory 44.

Title: Device for preventing evaporated fuel loss
Inventor: ANDA KOUSUKE
IPC: F02M25/08
Filed: 1982-04-23
Abstract: PURPOSE:To prevent evaporated fuel from being diffused into the ambient air, by actuating a solenoid valve upon the saturated condition of a fuel absorbing member in a canister so that evaporated fuel in a fuel tank is introduced into an air cleaner and a crankcase. CONSTITUTION:Upon engine operation, evaporated fuel in a fuel tank 58 is introduced into a canister 12 through evaporated fuel passages 60, 62 since a solenoid valve is deenergized so that it is held in its close position, and is therefore absorbed by a fuel absorbing member 18. The absorbed fuel is suitably sucked out to an intake-air passage 42 through a discharge passage 45. Thereafter, when a detector means 44 for detecting the saturated condition of the fuel absorbing member 18, generates its output, the solenoid valve 14 is opened through a control means 16, and therefore, the evaporated fuel passage 60 is communicated with a passage 64, instead of the passage 62 to which it is previously communicated. Thereby, evaporated fuel is introduced into an air-cleaner 10 and a crankcase 67, thereby evaporated fuel is prevented from being diffused directly into the ambient air.

Abstract: PURPOSE:To take out high energy with good space efficiency by filling a sealed deformable container with a high pressure material and generating mechanical energy from the deformable part of the container with a change across the critical temperature of the high pressure material. CONSTITUTION:A Bourdon tube 1 formed with a flat circular arc shaped pipe has a closed pressure detecting port which is used as a rotation pointer pressure gauge, is filled with carbon dioxide as a high pressure material. A rack 2 supported by a left end part meshes with a pinion 4 through a spring 3 pressing it upward.

Conversely, the rack moves rightward depending on the fall of temperature, so that the pinion 4 rotates and then, mechanical energy can be taken out from the shaft thereof. Accordingly. the energy can be generated by using the temperature change in the nature with no positive feed of energy from an external part.
