Title: Decision apparatus for efficiency of storage battery
Inventor: NAKAZAWA SHIYUUJI
IPC: G01R31/36
Filed: 1979-10-18
Abstract: PURPOSE: To decide the good or bad of the storage-battery electrolyte or the like as a link in the chain of the total control system of a motor-vehicle or the like by deciding the good or bad by the comparison of the difference between the storage- battery terminal voltages when the terminals are open and when a backward current flows in with a given voltage.  
     CONSTITUTION: Through a CPU and I/O in a microcomputer 27, a switch 24 is closed for a short time. Consequently a backward constant current from a constant- current source 23 is supplied for a storage battery. The voltage across terminals 21 and 22 of the battery is detected and converted into a digital value before being stored in a RAM in the computer 27. Similarly, the digital detection voltage across the terminals 21 and 22 of the battery when the switch 24 is open is stored in the RAM in the computer 27. The difference between these stored voltages and a reference voltage stored in a ROM are compared to decide the condition of the battery, which is displayed on a display 28. The constitution permits the decision of the good or bad of a storage battery based on the change in quality of its electrolyte or plates which causes the internal resistance to increase and the voltage to fall, as a link in the chain of a total control system of the motor-vehicle or the like.

Title: Image signal processing circuit
Inventor: IGUCHI SUSUMU
IPC: G02B3/00
Filed: 1987-06-01
Abstract: PURPOSE:To prevent the accuracy of focus detection from decreasing by applying a correction voltage in synchronism with lock pulses and inhibiting a negative-voltage difference signal from being outputted from a differential amplifier circuit even when an image signal with an excessive amplitude is received. CONSTITUTION:The correction voltage which synchronizes with clock pulses phi1 is applied to at least one input terminal 4 of the differential amplifier circuit 8, which outputs no negative voltage differential signal even when the image signal with the excessive amplitude is received while superposed upon the clock pulses phi1. Therefore, a logarithmic compressing circuit (logarithmic amplifier 14) which receives the differential signal is therefore prevented securely from having response delay. Consequently, the accuracy of focus detection is prevented from decreasing.

Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To divide easily while maintaining cushioning function, eliminate storage-space limit, and improve the rate of storage or the rate of recycling recovery for reusing resources. SOLUTION: In both top packing cushioning-medium 11 and bottom packing cushioning-medium 21, notches 16 and 26, respectively, are made in parts where shock absorption effect is not required, they are not locked into the position of a television-receiving machine 1, an item to be packed, in contact with it, and shock absorption exerts an adverse effect on the product, and thin parts 12a and 24a, respectively, are also made in them. Thus, they can sufficiently withstand shock caused during transportation, and because dividing into two reduces volume before the division to half, each takes up only 1/2 storage space. Therefore, even in the case the packing box 4 is folded into a compact form and only the packing cushioning-mediums 11 and 21 are stored separately from it, they take up little space and also it is easy to send for recycling recovery.

Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To directly dissolve mingled matter which is captured and to prevent the mingled matter from depositing on an electrode by providing catalyst which decomposes the mingled matter on the electrode surface which captures the electrified mingled matter by photoelectrons. SOLUTION: Ultraviolet radiation 3 radiated from an ultraviolet lamp 2 reaches photoelectron emitting member 5 passing through a quartz supporting plate 4 and emits photoelectrons 6. The emitted photoelectrons ionize mingled matter and the ionized mingled matter is attracted by an electrode 9 having an inverted potential of electrified charge by an electrical field. Mingled matter decomposing catalyst 8 exists on the surface of the electrode 9, therefore the mingled matter is decomposed by the catalyst 8 and eliminated as decomposed products 11 from the electrode surface. By the means a device need not be periodically stopped for eliminating the mingled matter adhering to the electrode, and contamination by the deposited mingled matter being rediffused in the device due to the operation of the mingled matter eliminating can be prevented.

Abstract: PURPOSE:To refine a high-cleanliness dead-soft carbon steel without decreasing decarburizing velocity by carrying out decarburizing treatment by means of a vacuum device by specifying respective concentrations of T.Fe and SiO2 in ladle slag and using a ladle refractory of specific SiO2 content. CONSTITUTION:A dead-soft carbon steel is refined by carrying out decarburizing treatment by means of a vacuum device. At this time, the concentrations of T.Fe and SiO2 in a ladle slag before vacuum degassing treatment are regulated to 0.5-8wt.%, by weight, and <=20%, respectively, and also SiO2 content in a ladle refractory is regulated to <=30%. By controlling the above-mentioned T.Fe and SiO2 contents, the total oxygen concentration in the steel as an index to cleanliness is maintained at a sufficiently low level and the decrease in vacuum decarburizing velocity can be prevented. By this method, the high- cleanliness dead-soft carbon steel reduced in inclusions in the steel can be refined without deteriorating decarburizing velocity.
