Title: Microwave solid oscillator
Inventor: SHIRAISHI MOTOI
IPC: H03B5/18
Filed: 1979-05-08
Abstract: PURPOSE:To enhance oscillation intensity to keep the loop gain maximum by using a high-pass filter which reflects almost all the fundamental oscillation frequency of an oscillation element and causes a high frequency to pass through. CONSTITUTION:When the resonance frequency of resonator 10 is denoted as f0, oscillation element 11 oscillates with frequency f0 approximately. Capacitance 12 is formed by close coupling so that frequencies f0 as well as nf0 can pass through it. Inductance 13 is set to a length of lambda/4 for nf0 and is so designed that it may be short-circuited for f0 to reflect all the frequency but may be open for nf0 not to have influence upon nf0. Meanwhile, capacitance 14 is so designed that it may be high- impedance for f0 and may be low-impedance for nf0. As a result, the oscillation frequency can be taken out in output 15 with total reflection for f0 and without little influence upon the original frequency for nf0.

IPC: H04B1/66
Filed: 1986-03-13
Abstract: PURPOSE:To send efficiently a MODEM signal by providing a coefficient table changing linearly a quantized step size in response to the level of an input signal, deciding the level of the input signal, selecting the value in response to the level to update the step size. CONSTITUTION:Coefficient tables 9-12 whose quantized step size is changed linearly in response to the level of the input signal are provided. Then a reproduced signal of the input signal being an output of an adder 7 or the input signal itself is used and a level deciding device 13' judges the input signal level. Then the table 14 selects the value in response to the level, which updates the quantized step size. When the input signal is changed, since the quantized step size approaches the linear relation, the MODEM signal is sent efficiently.

Title: Rotary head for magnetic recording/reproducing device
Inventor: UMEHARA HIROSHI
IPC: G11B5/53
Filed: 1988-03-09
Abstract: PURPOSE:To improve the attachment accuracy of a magnetic head to a rotary drum by specifying the distance between gaps of two magnetic heads as well as the error of the height position of said gap. CONSTITUTION:The distance between gaps 5 and 5 of two magnetic heads 2a and 2b is set at the value approximately equal to an odd multiple of the folding value between the adjacent tracks on a tape. At the same time, the shift of the height position said gaps 5 and 5 is set at the value approximately equal to an odd multiple of the track pitch P. Thus it is possible to set the paired heads 2a and 2b extremely close to each other on a rotary drum 1 and therefore to fix both heads on the same head base or to form these heads in a single body. As a result, the magnetic heads can be easily attached to a rotary drum with high accuracy.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that humidity in a room is lowered due to ventilation in winter or the like by using a total heat exchanger and a dry dehumidifier for humidifying air supplied by humidified air exhausted from the total heat exchanger. SOLUTION: Humidified air exhausted from the outside air exhaust port 1b of a total heat exchanger 1 is taken to a dry dehumidifer 2 from an air intake 2a, its moisture is absorbed by a moisture absorbing rotor 7 and dehumidified air is exhausted from a dehumidified air exhaust port 2b by a blower 8. Further, the air taken from the air intake 2a which is to be dehumidified is sucked by a blower 9, heated by a heater 10, and the heated air is supplied to other position of the moisture absorbing rotor 7. Water absorbed by the moisture absorbing rotor 7 is exhausted and the humidified air is exhausted from a humidified air exhaust port 2c. Since the humidified air exhaust port 2c communicates with an indoor side air supply port 1d, the humidified air obtained from the dry dehumidifier is supplied to a room 5 via the indoor side air supply port 1d.

IPC: B42D15/10
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To provide an information recording medium not only satisfying the basic performances as the information recording medium but also being processed by a machine. SOLUTION: In the constitution of a recording medium, at least a magnetic layer 2 of lightproofness, an information layer 5 having recorded informaitons to be masked thereon and formed on the magnetic layer and a releasable masking layer 6 masking the information layer are formed on one face of a base, or else, at least an information layer 5 having recorded informations thereon and a releasable masking layer 6 masking the information layer are formed on one face of a base and at least a magnetic layer 2 of lightproofness is formed on the other face of the base.

Filed: 1988-03-11
Abstract: PURPOSE:To restrain the development of shrinkage hole and to improve the productivity by executing injection or projection of solid grains at the time of cooling a cast billet drawn from a mold. CONSTITUTION:Molten metal supplied from a nozzle 1 is cooled in the mold 3 circulating cooling water through an inlet 4 and outlet 5 and the solidification is started to make the cast billet 10, and the cast billet is continuously drawn downward. At the exposed place of the cast billet 10 from the mold 3, blasting material injected with pressurized gas of air, etc., from an injection nozzle 8 or projected with impeller 9 is collided to the cast billet 10 to cool the cast billet 10. By this method, the solid-liquid coexisting zone is shortened and the development of the shrinkage hole in the cast billet can be restrained. Further, the casting speed can be increased and even if break out happens, possibility of explosion is eliminated.

Title: Anti-freeze valve
Inventor: MORIMOTO SHIGERU
IPC: F16K17/38
Filed: 1982-04-05
Abstract: PURPOSE:To prevent gas from leaking from a sealing tube which contains a thermosensitive gas by filling a hollow which is bottomed by caulked part of the sealing tube, with molten solder and making said caulked bottomed by caulked part of the sealing tube, with molen solder and making said caulked part welded. CONSTITUTION:A caulked part 25 of a sealing tube 24 is cut at its upper part without crushing the cut section 26. A solder 28 is poured in a hollow 27 which is formed between the cut section 26 and the caulked part 25 so that the caulked part 25 may be welded. Since the hollow 27 on the caulked part 25 of the sealing tube 24 is deep and the solder 28 is thick, any pin-hole will not be allowed to form in the solder 28 and the boundary surface between the solder 28 and the hollow 27 may be elongated. Because of the reason, if gas 23 may pass through a gap at the caulked part 25 to reach the hollow 27, there will not be any chance that the gas 23 may leak outside the sealing tube 24.

Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To prevent a type of a scanning system from being misdiscriminated by discriminating the scanning system whether it is the interlace scanning system or the noninterlace scanning system every time a scanning system discrimination exclusive signal is raised. SOLUTION: A synchronization circuit of a VSYNC(vertical synchronizing signal) by using a HSYNC(horizontal synchronizing signal) starts a field discrimination circuit by a trailing timing of the HSYNC signal. The field discrimination circuit reads 1st information denoting whether a field just before the trailing timing point is an ODD field or an EVEN field and reads 2nd information denoting whether one preceding field to the field relating to the 1st information is an ODD field or an EVEN field. Then the discrimination circuit discriminates the scanning system based on the information of the type of the 1st and 2nd fields.
