Title: Optical recording system for digital information
Inventor: NISHIMURA KAZUTOSHI
IPC: G11B20/10
Filed: 1984-06-29
Abstract: PURPOSE:To realize the optical recording system which records and reproduces digital information with high density and high reliability by recording bits ''1'' of a recording bit sequance on a recording medium as a unit recording part separated mutually by an unrecorded part or unrecorded part separated by a recording part. CONSTITUTION:A reproduced data bit sequence A is inputted from an information processor to an encoder 1, which converts the sequence A into a sequence B which contains (d) (integer larger than 1) - (k) [integer larger than (d)] bits ''0'' between successive bits ''1''. This sequence B is inputted to a recording pulse generator 2, which generates a recording pulse (a) wih specific width for every bit ''1'' to generate a recording pulse sequence C. Then, the sequence C is sent out to an optical recording head 3, which responds to a pulse (a) in the sequence C to irradiate a recording medium 4 with recording light, thereby forming a sequence D of unit recording parts (b) on the medium 4. Then, the sequence D is reproduced to obtain a reproduced pulse sequence E and each peak point (d) of this sequence E corresponds to a bit ''1'' in the sequence B. Thus, peak detection and clock reproduction are performed to reproduced the original data bit sequence A.
Patent JP-S5467752-A (JP)
Title: Multivibrator
Inventor: TAKANO HISAO
IPC: H03K3/02
Filed: 1977-11-10
Abstract: PURPOSE:To obtain a multivibrator which changes the output pulse width and the oscillated frequency according as the power supply voltage changes by utilizing the change of the supply voltage, which is a feature of C-MOS (complementary MOS) IC, as well as the threshold voltage and the output voltage change point. CONSTITUTION:Assuming that the ''H'' output is outputted from inverter INV and negative pulses are applied to input terminal IN, the input and the output of NAND gate NAND are ''H,H'' and ''L'' respectively before negative pluse input. However, when negative pulses are applied, the output of NAND becomes ''H'' since the input of NAND becomes ''L,H'', and these signals are differentiated by a differentiating circuit constituted by C and R2 and are inputted to INV. Therefore, INV holds the output at ''L'' until the differentiated output becomes below the theshold voltage of INV. When the differentiated output becomes below the threshol voltage, the output of INV returns to ''H'' and the output of NAND becomes ''L'' because IN is normally ''H''.

IPC: B22F3/10
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To uniformly and sufficiently degrease in a short degreasing time by executing the degrease in a low temp. range at a first process and the degrease in a further higher temp. range at a second process and mutually changing over the degreasing atmosphere at the first process from the reduced pressure state to higher pressure state than the former state. SOLUTION: At the first process, the temp. in a furnace is raised by operating a heater for a prescribed time (a first pattern) and successively, the temp. in the furnace is kept at the constant for a prescribed time by stopping or reducing the output of the heater (a second pattern) and after this, these operations are repeated. In this result, the temp. in the furnace is raised step by step. Then, related to the pressure in the atmosphere, in the first pattern, a second pressure is set, and in the second pattern, a first pressure, desirably <50 Torr is set. The second pressure is made slightly higher than the first pressure and the difference between these pressures is desirable to be >35 Torr. Further, as the degreasing gas, the inert gas of nitrogen, argon, etc., is suitable from a viepoint of preventing the change in quality of the compact.

Title: Method of controlling ignition timing of electronically controlled engine
Inventor: MATSUOKA HIROKI
IPC: F02P5/04
Filed: 1981-08-31
Abstract: PURPOSE:To prevent over advancing of the ignition timing due to overshoot, by employing such an arrangement that the ignition timing is calculated on the basis of a correction value of the quantity of intake air drawn per one rotation of an engine in case that overshoot is caused with an air flow sensor. CONSTITUTION:In order to detect occurrence of overshoot, comparison is made between a correction value P and the quantity Q/N of intake air drawn per one rotation of an engine. In case that no overshoot is caused with an air flow sensor, the value Q/N is used directly at a step 70. However, if overshoot is caused with the air flow sensor, the correction value P is used at a step 69. The ignition timing is calculated by use of the values N and Q/N corrected in the above-mentioned manner, whereby it is enabled to prevent faulty control of the ignition timing due to overshoot.

Abstract: PURPOSE:To suppress a waste of an ozone decomposing agent by forming an air discharge duct of a bent pipe having >=1 bent parts, providing an ozone decomposing means at the bent part and adjusting the discharge flow passage length of the air discharge duct with ozone concentration. CONSTITUTION:The air discharge duct 2 consists of the bent pipe provided with >=1 bent part 5 and the ozone decomposing agent 6 is provided in the bent part 5. Ozone containing discharge air in a device 1 which is sucked by an air discharge fan 4 is diffused as a turbulent flow by the bent part 5 when passing through the air discharge duct 2 and reacts on the ozone decomposing means 6 and is decomposed when mixed with the ozone decomposing means 6 and passed though the air discharge duct. Thus, when the ozone concentration in the device, i.e. the concentration of the ozone flowing in the air discharge duct decreases, the length of the flow passage is shortened to discharge the high-temperature air speedily from the device. In this case, a means which adjusts the flow passage length of the air discharge length consists of an opening /closing valve which connects and disconnects adjacent tube parts. Consequently, the waste of the ozone decomposing means can be suppressed.

Title: Continuous kneading machine
Inventor: OTAKE SHOSUKE
IPC: B01F7/04
Filed: 1992-04-28
Abstract: PURPOSE:To improve kneading efficiency together with self-cleaning and to lessen the wear of paddles. CONSTITUTION:The paddles rotate while the peak parts 8c of the major diameter parts 8a of the one paddle come into contact with the peak parts 9d of the minor diameter parts 9b of the other paddle 9 or the peak parts 8d of the minor diameter part 8b of the one paddle come into contact with the peak parts 9c of the major diameter parts 9a of the other paddle 9, when the one paddle 8 and the other paddle 9 are rotated in directions different from each other and at different speeds. Two material spaces (max. space areas) are formed together with the rotation. The materials are then begun to join and are successively compressed until the materials are largely compressed in the one narrow material space. The chances of surely mingling with each other and coming into frontal collision are thereby increased. The materials are thus uniformly mingled with each other. In addition, the number (n-set) of the major diameter parts and minor diameter parts of the one paddle and the number (m-set) of the major diameter parts and minor diameter parts of the other paddle are not equal and, therefore, the materials are further effectively kneaded.
