Inventor: TADAMI MITSUSHIGE
IPC: H04N9/83
Filed: 1987-04-17
Abstract: PURPOSE:To simplify the circuit constitution by using a frequency converting circuit applying high frequency conversion to a low frequency conversion chrominance carrier signal in a color video signal to PAL system and restoring it into the original chrominance carrier signal in common use with a frequency converting circuit obtaining the polarity of the V axis signal of the obtained chrominance carrier signal and the inverted polarity.

Title: Electroacoustic transducer
Inventor: NADA TAKATOSHI
IPC: H04R17/00
Filed: 1985-05-02
Abstract: PURPOSE:To transmit a wave at a lower frequency with larger sound pressure while maintaining moisture resistance by composing a transducer of a piezoelectric element and a shell and decreasing the thickness of the shell gradually from ends to the center. CONSTITUTION:The piezoelectric element 1 is formed by laminating many plate type ceramic elements and connected together electrically in parallel, and large displacement is obtained with a relatively low voltage. The shell 2 decreases in thickness gradually from connection parts of piezoelectric elements to the center of the shell. The shell 2 uses high tension strength steel preferably such as manganess zinc ferrite so as to realize frequency reduction and moisture resistance. The shell 2 is extended before the piezoelectric element is put in, so compressive force is applied to the piezoelectric element after the piezoelectric element is put in. The thickness of the shell is decreased gradually from the long-diameter parts to the short-diameter part, and consequently the weight is lighter, the frequency is lower, and efficiency is better than a conventional shell which is uniform in thickness while the moisture resistance is maintained.

Abstract: PURPOSE:To shorten the time required for spraying by uniformly spraying respective powders in independent states on an objective substrate by electric lines of force and driving the powders toward the objective substrate by the effect of electric fields. CONSTITUTION:A corona discharge is induced in a corona discharge electrode 7 at the front end of a nozzle body 1 by a power source 5. A closing/opening mechanism 9a in the bottom of a powder supplying device 2 is instantaneously opened while the uniform electric field intensity is formed on the surface of the objective substrate 14 between the electrode 7 and a grounding electrode 16. Gas is simultaneously fed toward an annular chamber 11 in the body 1. The metered powders 9 falling by gravity are powerfully agitated by the gas ejected from an outlet 12 and are uniformly dispersed in a dispersing region 13 The dispersed powders 9 fly in the form of a flying powder layer 15 forming a thin layer in parallel with the substrate 14 toward the substrate 14 along the electric lines of force between the electrode 7 impressed with a high voltage and the substrate 14. The respective powder particles are driven and sprayed to the substrate 14 along the electric lines of force 18 without flocculating each other. The respective sprayed powder particles 19 are thus uniformly sprayed in the independent state.

If arrival pulse A exists at input terminal 1 at the time point when read/write circuit 10 reads out the contents of RAM9 in the corresponding address and the contents are set to shift register 12, the bit of the 0-power digit of 2 in register 12 is turned on through timing circuit 11 with shifting of the contents and then turned off if no pulse A exists with the contents shifted respectively. The renewed contents of register 12 are written 10 again into RAM9. The informtion stored in RAM9 is the hysteresis of pulse A before a fixed time.

IPC: F02F5/00
Filed: 1986-04-24
Abstract: PURPOSE:To reduce the consumption of oil, by forming the abutment section of a top ring in such a shape that the opening area on the combustion side is greater when the top ring is seated on the lower surface of the ring groove, than the opening area on the second land side when the ring is seated on the upper surface of the ring groove. CONSTITUTION:A top ring 22 and a second ring 24 are disposed in ring grooves 18, 20 in a piston 10. The abutment section 22a of the top ring 2 is formed such that the opening area on the combustion chamber 16 side is greater than the opening area on the second land 26 side. Therefore, the top ring 22 is seated on the lower surface of the ring groove 18 during initial stage of every combustion stroke, so that the opening area S2 of the abutment section 22a allows the combustion pressure to be introduced into the second land 26 to raise the pressure thereof, and when the ring 22 is sealed on the upper surface of the ring groove 18, the displacement of oil from the second land into the combustion chamber 16 is resisted by small opening area S1, thereby it is possible to reduce the consumption of oil.

Title: Copying system for magnetic disk
Inventor: KAMANO HIRONOBU
IPC: G11B19/02
Filed: 1991-04-25
Abstract: PURPOSE:To check whether the occurrence area of an input error is in a file or not, to unconsciously copy a magnetic disk by an operator if the occurrence area of an input error is outside the area and to save the operator the trouble for checking and judging whether the area is the inside of the area or not while interrupting copying processing at the time of copying the magnetic disk. CONSTITUTION:At the time of reading a magnetic disk 11, an input error detecting mechanism 13 checks whether the input error arises or not. When the input error is detected, a file area managing mechanism 14 judges whether the address of the currently occurred input error is in an allocated area as a file area or not by means of the starting and the ending addresses of the respective file areas. When it is the outside of the area, the data are transferred to a data writing mechanism 16 and, if the inside, the fact that the error arises is transferred to a message display mechanism 15 so as to display the message.

Filed: 1980-07-15
Abstract: PURPOSE:To enable the head to be capped and to prevent electrodes from being smudged by drops of ink by a method wherein a charge electrode and a deflection electrode are held on a stand-by position and an ink jet head alone is moved to the home position. CONSTITUTION:When the head 4 is in the stand-by position B and in the printing zone, an electrode body 6 is held at a predetermined interval to a hold plate 11 by the deflection force of coil springs 10, 10' mounted respectively on slide shafts 9, 9.'. As a result the charge electrode 7 and the deflection electrode 8 are held at a defined position in the jetting direction of ink. When a main switch is turned off at this stand-by position B a carriage 5 allows the head 4 to move to the home positon A but since a stopper 13 is provided in the opposite part of the electrode body 6, the electrode body 6 is held at the stand-by position B and the head 4 alone moves to the home position.

The electrophotographic sensitive layer (the charge generating layer and charge transfer layer) in the non-image part which is not masked by a toner image is dissolved away and the hydrophilic surface of the conductive base is exposed so that the image part coated with the lipophilic toner remains on the printing plate obtd. by forming the toner image on the original plate when said printing plate is immersed into an alkaline eluting soln. Thus oil ink sticks only on the image part in ordinary lithographic printing and the good printed matter having no ground stains is obtd.
