Title: Temperature sensitive amorphous magnetic alloy
Inventor: INOMATA KOUICHIROU
IPC: C22C45/02
Filed: 1981-02-10
Abstract: PURPOSE: To enhance the temp. sensitivity by adding Co, Ni and one or more among P, B, C and Si so as to provide a prescribed composition.  
     CONSTITUTION: The titled alloy has a composition represented by a formula (Co 1-a Ni a ) 100-z X z  (where X is one or more among P, B, C and Si, (a) is 0.2W 0.8 and (z) is 15W20). In the composition ≤5 atomic% Cr may be substituted for the Co. The alloy undergoes a large change in the magnetic permeability due to temp. close to the Curie point, and the temp. range of the change is narrow, so the permeability is changed sharply. The setting temp. is changed to ≤200°C.

Title: Fm receiver
Inventor: SAITO KOICHI
IPC: H03D3/00
Filed: 1986-01-28
Abstract: PURPOSE:To hold a C/N to a constant value or above and to minimize the deterioration of a signal by compressing the frequency deviation of the signal and passing most of the input signal necessary with a narrow band width. CONSTITUTION:A part of the demodulating signal outputted from a demodulation circuit 9 is given to a compressing control circuit 11 and an extending control circuit 14. For the first local oscillating wave of the first local oscillation circuit 6, the frequency deviation of the first intermediate frequency is controlled to be compressed by the compressing control circuit 11 in accordance with a demodulating signal, and the first intermediate frequency passes through a band filtering circuit 7 with a narrow band width. Further, the second local oscillating wave of the second local oscillation circuit 13 is frequency-deviated to the phase reverse to the frequency deviation of the first local oscillating wave by the extending control circuit 14. The frequency deviation of the second intermediate wave outputted from the second frequency conversion circuit 12 is controlled to be extended in accordance with the demodulating signal and to be restored to the signal of the frequency deviation before it is compressed by the first frequency conversion circuit 5. Thus, the output level of the demodulating signal outputted from the demodulation circuit 9 is not reduced and the S/N is not deteriorated.

Title: Color picture tube
Inventor: SAITOU YUUJI
IPC: H01J29/02
Filed: 1978-02-17
Abstract: PURPOSE: To obtain a high-quality picture tube featuring the reduced earth magnetism effect by providing a simple correction plate assembly within the picture tube with which the beam landing error caused by the earth magnetism is minimized for the picture tube screen as a whole.  
     CONSTITUTION: Vertical magnetic plate 11 is provided to short-side surface 10 of the frame of shadow mask assembly 1, and horizontal magnetic plate 13 is attached to the upper and lower part of outer end 12 of the frame. Thus, the magnetic field close to the screen circumference among the vertical magnetic fields is inducted to plate 11 to vary the magnetic field distribution at the passage region of the electron beams. Furthermore, the vertical AC magnetic field which is most effective to the magnetic erasion of the shadow mask passes through the shadow mask both in the upper and lower directions since plate 13 has a gap between the plate and frame long side 14. As a result, the perfect magnetic erasion is ensured with virtually no lowering of the magnetic erasion effect. In such constitution, the earth magnetism is not shut out but the landing error of beam 7 is minimized for the picture tube screen as a whole, thus obtaining a high-quality glass picture tube.

Title: Remote controlled electric water heater
Inventor: HATTORI MASAJI
IPC: F24H1/18
Filed: 1989-01-27
Abstract: PURPOSE:To improve a highly reliable quality of inspection and service by installing flow rate, water leakage, and electric current sensors to detect and display the generation of troubles as early as possible, and furnishing a system control apparatus with a main body which is easy to inspect. CONSTITUTION:At the same time when a water supply motor-driven valve 6 opens and starts the supply of water, a flow rate sensor 18 detects a spontaneous flow rate and transmits an output signal to a control means 23. When an integrated flow rate is calculated and high water level is detected in the control means 23, an air vent valve 16 is closed and water supply comes to a halt. On the contrary when the air vent valve 16 is clogged with dust or the like, the performance is carried out as indicated by a dotted line 26. When water supply has filled to reach a fixed integrated quantity of water no matter how long time has passed since the start of water supply, a number which depicts the shortage of water supply, is lit up on an indicator 24. When a hot water storage tank 1 is subject to water leakage, a water leak sensor detects the water leakage and lights up a water leak number. When an electric current value of a heater 2 drops below a fixed current value during boiling operation, an electric current sensor detects this, and lights up a heater trouble number. In this manner, this control performance, even remote controlled, makes it possible to facilitate troubleshooting during emergency.

IPC: F02B75/18
Filed: 1984-02-06
Abstract: PURPOSE:To aim at improvements in suction volumetric efficiency at the whole operation range, by installing a valve in a pipe line interconnecting suction pipes one another branched from the downstream side of a surge tank to each cylinder, while making it open in time of high revolution. CONSTITUTION:A suction pipe is branched from a downstream surge tank 4 at the down-stream side of an air cleaner 7 to suction passages 3a-3d for each cylinder.

Title: Sealed contact material
Inventor: HIRASAWA TAKESHI
IPC: H01H1/04
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive sealed contact material having a long contact service life even under a highly loaded conditions. SOLUTION: This material is the one in which a coating layer having >=0.1μm thickness is formed on a contact base material, and this coating layer has a compsn. contg. at least one element among Zn, Cd, In, Tl, Sn, Pb, As, Sb and Bi by 0.5 to 50at%, contg. at least one element of C and Si by 5 to 50at%, contg. 0 to 40at% O (oxygen), and the balance >=30at% Cu or Ag. Since the material contains adhesion reducing elements such as Zn, Cd, In, Tl, Sn, Pb, As, Sb, Bi or the like and furthermore contains arc damage dispersing elements of C or Si, adhesion does not occur between contacts even under high loads in which arc discharge is generated, and a good contact service life can be obtd. Moreover, it is inexpensive since expensive Rh, Ru, etc., are not used.

Title: Method for display of erroneous input of random access on reproducing device with information recording carrier
Inventor: YOSHIDA MASARU
IPC: G11B20/18
Filed: 1981-02-13
Abstract: PURPOSE:To facilitate the correction of an error item, by displaying clearly the error item when an address which does not exist is accessed. CONSTITUTION:The output of a comparator 2 is inverted when an address read in the stage of the retrieval on every tracks corresponding to one rotation becomes larger or smaller than an object address. Values of addresses read in retrieval for normal reproducing just before and after this inversion are compared with the value of the object address inputted to an input part 1 to discriminate whether the object address exists or not. If the object address does not exist, a part in which the object address is different from a maximum address smaller than the object address (or a minimum address larger than the object address) is detected. This different part is displayed on a display part 4 to indicate that the inputted object address does not exist.
