Title: Sheet material reversing and carrying device and image forming device
Inventor: ARAKI TOMOYUKI
IPC: G03G15/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To perform the carry-in of a following sheet at the time of reversely rotating a carrying roller so as to perform the image forming processing at a high speed by controlling the sheet material carrying force by a reverse carrying roller with a change-over operation. SOLUTION: When a flapper 14 having a roller 15 as a rotating member at a position opposite to a reverse carrying roller 16 is switched to a carrying passage to a face-up discharging port, the roller 15 is made to abut on the reverse carrying roller 16. When the flapper pipe 14 is switched to a carrying passage to a face-down discharge port 26, the roller 15 is separated from the reverse rotating carrying roller 16. With this structure, since the roller 15 can be separated from the reverse carrying roller 16, even in the cease where the reverse carrying roller 16 is rotated in the opposite direction of the carrying roller 11, carry-in of a following sheet can be performed.  Namely, when a following sheet material exists, a tip of a former sheet material, which is switched for back, is detected by a sensor, and thereafter, the flapper 14 is switched to a real line position, and a following sheet can be led in.

Title: Magnetic memory medium
Inventor: SATO HISATERU
IPC: G11B5/65
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic memory medium which is capable of recording information with a high recording density and reproducing the information with high signal quality (a high S/Nn) and has a good overwriting characteristic while achieving the longer life of the recorded information. SOLUTION: This magnetic memory medium has a recording layer 3 on a nonmagnetic substrate 1. The recording layer 3 has ferromagnetic particles 3.1 consisting of ferromagnetic material and a antiferromagnetic matrix 3.2 consisting of antiferromagnetic material. Since the ferromagnetic particles 3.1 in the magnetic recording layer 3 are parted from each other by the antiferromagnetic matrix 3.2, the magnetic recording layer 3 is adequate for recording of the high density. Since the exchange interaction acts on each other between the ferromagnetic particles 3.1 and the antiferromagnetic matrix 3.2, the magnetic information recorded on the magnetic recording layer 3 is stable against thermal fluctuations and is maintained for a long time.

IPC: C22C49/08
Filed: 1988-04-01
Abstract: PURPOSE:To improve the strength of a composite material by compounding a fiber reinforcement and a base metal of Al alloy containing specific amounts of Ni. CONSTITUTION:As a fiber reinforcement, a continuous inorganic fiber, such as Si-Ti-C-O fiber, SiC fiber, alumina fiber, and carbon fiber, a continuous metallic fiber such as stainless-steel fiber, a short fiber, such as the whisker of SiC or Si3N4, and the like are used.

IPC: F24F11/76
Filed: 1989-03-31
Abstract: PURPOSE:To prevent the hunching problem of damper of VAV unit (variable air volume unit) by modulating the load reset value which limits the capacity range increment according to the air conditioning parameters in a variable air volume control system for respective locations to be air conditioned. CONSTITUTION:The regulators 7-1-7-n for subject rooms to be air conditioned 6-1-6-n controls the damper opening of the VAV units 8-1-8-n at the respective outlets diverging from the air supply duct 5 according to the deviation between the set temperature and the measured values from temperature sensors T-1-T-n. In this instance, if the deviation exceeds the predetermined value even at the maximum damper opening, a load reset command to increase the capacity for the blown supply air temperature is outputted to a control device 4 through a signal line L to quickly resolve the inadequacy of load condition. In a case where the load reset is performed according to the capacity increase demand during the heating or cooling operation, the capacity for the blown supply air temperature is increased at a suitable rate of speed to prevent an overshooting of the load condition of the subject rooms to be air conditioned 6-1-6-n back to the load reset deviation range so as to prevent the damper hunching.

Filed: 1979-06-22
Abstract: PURPOSE: To prevent the useless waste of tape delivery time, by comparing the stop condition from the processor with the count started with the readout and write-in of data and delivering the stop signal when the stop condition is established.  
     CONSTITUTION: In the magnetic tape unit (IOU), the magnetic tape feed stop condition from the processor is set to the condition memory means (CREG). When the interface circuit (IFC) starts the readout and write-in, the monitor circuit starts the count. The comparison circuit (CMP) compares this count value with the value of CREG, and the count value is greater, then the feed stop signal is delivered to the interruption transmission circuit (TRP) and the drive circuit (DRV). The circuit DRV stops magnetic tape with this signal and the circuit TRP feeds the interruption of the establishment of stop condition to the processor via the circuit IFC.

Filed: 1984-04-19
Abstract: PURPOSE:To increase heat transfer rate remarkably by a method wherein inclined bridge type cut-ups and louver type raised slots, having an inclined angle to a fin and penetrating from the front surface to the rear surface of the fin, are provided alternately and continuously. CONSTITUTION:Flon refrigerant, flowing in copper tubes 11 in the condition of two-phase flow, transfers the heat thereof to fin collars 12, fins 13, bridge type raised slots 14 and louver type raised slots 15, formed by aluminum, and effects heat exchange between air flowing from the direction of arrow sign C in the diagram. Re-adhering phenomena of air to the raised slot surfaces are generated in a boundary layer formed above the bridge type raised slot 14 since the flow of air, flowed thereinto by the louver type cut-up 15, collides against the upper surface of the bridge type raised slot 14. According to this method, the heat transfer rate on the upper surface of the bridge type raised slot 14 may be increased remarkably.

Abstract: PURPOSE:To improve temp. measuring performance and to exactly control a sample temp. by forming a fine wire and thermocouple coated with an insulation coating protective film on the surface on a plane base plate. CONSTITUTION:Platinum 2 and platinum 13% rhenium alloy 3 are formed by a printing method on a 96% alumina green sheet substrate 5 having 2.3mm thickness and 2X2cm plane size. The platinum 2 and the alloy 3 constitute heaters. Since both are in contact with each other in the central part, this part is the thermocouple 1. The insulation coating protective film 4 of 60 micron thickness is thereafter formed of 96% alumina paste in the parts exclusive of the part where electrodes 6 are taken out. This sheet is sintered to form a base plate hater. The temp. is measured by the thermocouple 1 in the central part which comes into contact with a sample from the rear surface of the sample having no relation with the outside shape necessary for determining surface tension. The thermal resistance of the sample and the thermocouple 1 is reduced by reducing the thickness of the protective film 4.
