Title: Electronic picture file system
Inventor: TANAKA KYO
IPC: G06F17/30
Filed: 1985-12-27
Abstract: PURPOSE:To decide easily whether picture data is registered normally or not as a picture file by writing register start information and register end information on a magnetic disk and an optical disk respectively. CONSTITUTION:When picture file register processing is started, the register start information is recorded on a hard disk 17. Then a picture file register means 200 compresses the picture data given from an image scanner 2 and writes it on an optical disk 5. In addition, the keyword information given from a keyboard 7 is written on the disk 5 together with retrieving information containing the start address, etc. of the picture data and its back-up information. When the processing is finished for plural pieces of picture data, the register end information is written on the disk 5 by an information writing means 201. While the register start information written previously on the disk 17 is erased. Thus it is possible to detect both states where the register start and end information are not erased through the disk 17 nor recorded respectively. This can easily decide whether the picture data is registered normally or not.

Title: Varnish treatment method for motor
Inventor: MURANO KATSUHIRO
IPC: H02K15/12
Filed: 1985-12-26
Abstract: PURPOSE:To eliminate the process of aftertreatment by holding varnish under the state, in which viscosity thereof is lowered at a specific temperature, dripping varnish and conducting thermosetting. CONSTITUTION:A stator 2 is placed on a frame 1 and immersed in a varnish tank in the varnish treatment of a small-sized motor. The inside of a winding 3 is impregnated with varnish, the winding is pulled up from the varnish tank and varnish is dripped, and the winding is heated and cured by a batch type furnace. Solventless varnish in which a thermosetting type curing catalyst as one part is added to 100pts. unsaturated polyester group varnish is used as varnish at that time. The temperature of the stator 2 is kept for 1hr at 80 deg.C, and thermo-set for 1hr at 130 deg.C. Accordingly, the generation of the marks of the adhesion of projecting varnish on the contact sections of the frame 1 with the stator 2 can be avoided, thus removing the process of the cut-off treatment process of the marks of adhesion.

Title: Gas flow rate sensor
Inventor: YAMASHITA TAKAHISA
IPC: G01P5/04
Filed: 1992-10-07
Abstract: PURPOSE:To make a gas flow rate sensor to hardly receive any influence from intake pulsation and, at the same time, to prevent an exhaust gas from getting worse by measuring the flow rate of air by changing the capacitance between a first and second electrodes by deforming the first electrode by an intake pressure so that the interval between the first and second electrodes can be changed. CONSTITUTION:The flow rate sensor 1 is fixed to an electronically controlled fuel injection system 40 with a nut 40. While the sensor 1 fixing position is largely affected by intake pulsation from an intake valve, the intake pulsation flows to the side faces of a frame 13 due to the rear shape of the frame 13 and does not give any influence to the electrode 11 of the sensor 1. On the other hand, the electrode 11 is deformed by the air flow which comes into collide with the electrode 11 and the capacitance between electrodes 11 and 12 changes. A capacitance detector detects the capacitance through electric wires 15a and 15b and outputs the capacitance as the air flow information in the system 40. Since the sensor 1 can be installed to the system 40 in such a way, the response of the sensor 1 can be obtained quickly and the problem generated in the transient control of engine firing can be solved, and then, the exhaust gas from the engine can be prevented from getting worse. In addition, since the sensor 1 is installed to the system 40 with the rear surface of the frame 13 on the intake valve side, the sensor 1 hardly receive any influence from intake pulsation.

Abstract: PROBLEM TO BE SOLVED: To thin a device, and suitably cool an inside in a portable personal computer and the like by generating distortion of expansion/contraction by alternating current voltage applied on a piezoelectric ceramics, blowing wind by standing wave vibration of a clearance between two parallel slab mediums 2, 3 generated by this distortion. SOLUTION: Two parallel slab mediums 2, 3 are arranged near to each other at prescribed clearances, and are fixed by a fixing tool 1. Piezoelectric ceramics 4a, 4b, 5a, 5b having a polarity and on which polarization process is applied, are stuck on each of parallel slab mediums 2, 3. Same alternating current voltage is applied between external surface of the piezoelectric ceramics 4a, 4b, 5a, 5b and the parallel slab mediums 2, 3, and thereby, the piezoelectric ceramics 4a, 4b, 5a, 5b are deformed, and the parallel slab mediums 2, 3 are also deformed. This deformation is repeated at intervals of resonance frequency of 20 kHz or more, and thereby, standing wave vibration is generated. It is thus possible to generate flow 7 of air by radiating pressure inside minor spaces.

Title: Thermal printer
Inventor: ONISHI MASARU
IPC: B41J35/36
Filed: 1985-12-25
Abstract: PURPOSE:To obtain recording images of fixed density regardless of the number of recordings by counting the number of recordings of ink layer exhaustion in a single stage recorded each time in a multistrike ribbon and varying energy applied to a thermal head for each count value. CONSTITUTION:If the top of ink layers 9 in an ink ribbon 7 is exhausted by a thermal head 3 for recording, the terminal 19 of the ink ribbon 7 fed out of a pulley 6 is detected by a photoelectric detector 16, and the detected output is counted by a controller 20 and stored. In the meantime, if the terminal 19 of the ink ribbon 7 is detected, the ink ribbon 7 is carried to 'Y' direction, wound around the pulley 6 and set to an initial condition. For instance, when the second stage of the ink layer of the ink ribbon 7 is used for recording at the time of second recording, a power value applied to the thermal head 3 is set to be larger than the first applied power value and recorded. Thus there will be no difference in the recording density of each stage of the ink layer 9, thereby improving image quality.
