Title: Magnetic recording and reproduction system for digital data
Inventor: OZAWA KOU
IPC: G11B5/09
Filed: 1978-11-29
Abstract: PURPOSE: To make it possible to record and reproduce digital data in format adaptive to respective system by using an audio recorder by converting digital data into a differential waveform signal and then by supplying it to a magnetic head.  
     CONSTITUTION: Pulse signal (a) of "1" and "0" varying in pulse width is supplied via attenuator A to a CR differentiating circuit, where respective change points of the signal are detected to obtain signal (b) of differential waveform, and the signal is supplied to amplifier B, whose output is recorded on a tape via magnetic head F. In reproduction, signal (c) read by head F is inputted to Schmitt trigger circuit E via amplifier D and states are inverted by preset signal levels U 1  and U 2  to shape  an analog signal into pulse signal (d), thereby leading a digital signal out. In this  way, digital data can definitely be recorded and reproduced.

IPC: B41M5/382
Filed: 1986-06-26
Abstract: PURPOSE:To print with a uniform density and favorable quality, by sending printing data for the preceding line to a head part by inverting the data, and supplying a preheating pulse signal to a thermal line printer head to heat the head to a predetermined temperature, after completing printing in one line and before printing in the next line. CONSTITUTION:When a printing in one line is completed, the printing data for the line are taken out through an OUT terminal of a shift register 13, and are inverted by an inverter circuit 7. The inverted data are inputted to an inverted printing data selector circuit 6, and are sent to and latched by a latch circuit 12 in response to a control signal from a preheating-controlling means 24 in a microcomputer 2. A preheating pulse signal determining means 22 for determining the width and number of pulses of a preheating pulse signal to be applied to a head 11 reads the temperature t'H of the head 11 detected from a temperature sensor 14. When printing is conducted at a regular time interval Tp, the printing period for the preceding line is subtracted from Tp to calculate a preheating period Th = (Tp-Pp), and the width PH and number NH of pulses of the preheating pulse signal are determined based on a preheating energy lookup table and the preheating period Th.

Abstract: PURPOSE:To automatically accurately detect an ignition angle as an electric signal based on the reading result of a CCD camera by a method wherein a timing mark on a pulley secured to the crank shaft of an internal combustion engine is read by scanning the CCD camera in synchronism with an ignition timing. CONSTITUTION:When an internal combustion engine 12 is of, for example, 4-cycle 4-cylinder type and driven at the number of idle revolutions, an ignition pulse is outputted from a distributor 21 on each occasion of 1/2 rotation of a crank shaft 15, and thereby the pulse is inputted to a CCD controller 19 and a computing device 20. Scanning of a CCD camera 14 is performed by a CCD controller 19 one time simultaneously with ignition of the ignition plug of the internal combustion engine 12. In which case, if a timing mark 17 is positioned on a CCD scanning line 18, the position is inputted from the CCD camera 14 to the computing device 20 through the CCD controller 19. This computes an ignition angle based on the position with the aid of the computing device 20.

Abstract: PROBLEM TO BE SOLVED: To impart rigidity to the whole bottle body, and prevent a deforming panel part from recessing by a gripping force even when the deforming panel part is gripped by hand by providing a deforming panel for which a plurality of valley-shaped deforming parts being constituted of tilted walls which tilt inward, are arranged, and a thin recessed groove is formed around the valley-shaped deforming parts. SOLUTION: On a wall surface 2 of the body part of a square bottle main body b1 made of a plastic, a plurality of valley-shaped deforming parts 31 being constituted of a tilted wall 311 which tilt inward from the wall surface 2 of the body par, are arranged, and at the same time, a thin recessed groove 32 is formed to surround the valley-shaped deforming part 31 to form a deforming panel part 3, and the deforming panel part 3 is provided on the wall surface 2 of the body part.  By doing so, a deformation of the bottle main body due to a pressure being generated in the bottle, is absorbed by a deformation of the deforming panel part 3, and at the same time, the rigidity of the bottle is strengthened by the wall surface of the body part between two valley-shaped deforming parts 31, as a lateral bridge 21, and for this reason, even when the deforming part of the bottle is gripped by hand, the spot is prevented from recessing by the gripping force.

CONSTITUTION:A suction pipe 1 and a crankcase 2 are communicated with a first passage 4, in which a valve 3 is interposed, while an air cleaner 5 and a cylinder head cover 6 are communicated with a second passage 8, in which a valve device 7 is interposed. The valve device 7 consists of a first check valve 10, the set pressure of which is determined by the spring pressure of a spring 9, and a second check valve 13, the set pressure of which is determined by the spring pressure of a spring 11 stronger than the spring 9 and which is equipped with the valve seat part 12 of said valve 10. Under the normal running conditions, the ventilation is performed by flowing fresh air into the cover 6 and the crankcase 2 by opening the check valve 10. When the pressure of blow- by gas rises temporarily, both the valves 10 and 13 are closed. Further, when the continuous excess of the pressure of blow-by gas over a predetermined pressure occurs, the check valve 13 is open while the check valve 10 remains closed.

Abstract: PURPOSE: To eliminate the need for a pump sucking a working fluid into a heater in a Rankine cycle engine operating with a low temperature working fluid by feeding back a working medium into a solution by use of a penetration pressure created at a semi-permeable membrane.  
     CONSTITUTION: A solution expanded to cause a pressure drop in a total flow turbine 2 is separated into a condensed solution and a solvent steam, which is fed into an expander 3. A pressure of the solution separated is reduced in a flash evaporator 6 to create a vapor partially raised from the solvent. The steam or the evaporated solvent is delivered to an intermediate stage of the expander 3 to run it along with said solvent steam remained therein and then condensed by a condenser 5. The resultant condensed solvent which is sufficiently dilluted with less solute  contained in it in comparison with the original solution, is mixed with it after passing through a semi-permeable membrane 10a, thereby eliminating the need for an ordinal pump which sucks a working medium into a heater 11.

Abstract: PURPOSE:To increase a magnetic optical effect without decreasing the quantity of reflection light, and also to easily provide a guide track, by forming an amorphous magnetic body on the upper film surface of a reflection layer, crystallizing a part of the amorphous magnetic body, and roviding the guide track. CONSTITUTION:On a substrate 1 of glass, etc., a vertical magnetizing film of an amorphous ferrimagnetic material such as GdTbFe, etc. is formed, on which a transparent dielectric film 4 such as SiO2, etc. is formed and moreover, a reflection film 5 such as Al, Ag, etc. is formed on the film 4. This recording element consisting of 4 layer structure is made to adhere to the reflection film 5 through an adhering layer 6 on a supporting body 7 such as glass, etc. A guide track 2 is formed by heating a guide track part 2 of an amorphous magnetic material film to a crystallization temperature or above by an Ar laser, etc., crystallizing it, and lowering the reflection factor. A recording temperature of the magnetic material film is about 100-150 deg.C, is lower than a crystallization temperature (about 350 deg.C, and thermal recording (bit 8) is formed in a recording track 3 repeatedly. As for a reproducing light beam, its S/N ratio is increased since the Kerr effect by reflection from the magnetic body surface is combined with the Faraday effect caused by the fact that said light beam passes through the magnetic material film, and passes through said film over again by the reflection layer 5.
