Abstract: A portable electric power source characterized by the fact an electric double layer battery is placed at a stage which follows a cell which generates electricity by receiving sunlight; and in which in order to produce current bit by bit from said electric double layer battery, the current capacity of said electric double layer battery is made smaller than the current capacity of a constant voltage secondary battery of a following stage; and which is further characterized by the fact that a DC--DC convertor is connected to the next stage, so that charging can be carried out at said constant voltage secondary battery even at an electric potential in which the output voltage of said electric double layer battery is lower than the voltage of the constant voltage secondary battery attached to the following stage.

Abstract: This invention relates to a 4-cycle in-cylinder injection internal combustion engine in which fuel is injected directly into a combustion chamber, and specifically to an in-cylinder injection internal combustion engine suited for use as an internal combustion engine which performs premixed combustion at the time of a high power output but stratified combustion at the time of a low power output and switches the state of each of the combustions depending on an operation state of the engine.

Abstract: A mesh belt type blackening lehr comprising: a discharge duct provided at a predetermined position of a ceiling of a blackening zone, the temperature of which is kept at a blackening temperature. The blackening zone is divided into a charge side region and a discharge side region. The charge side region is kept in an atmosphere of mixture gas of air and humidification exothermic type gas so as to perform first processing for forming an oxide film consisting of Fe.sub.2 O.sub.3, Fe.sub.3 O.sub.4, and FeO. The discharge side region is kept in an atmosphere of humidification exothermic type gas so as to perform second processing for reducing Fe.sub.2 O.sub.3. Thus, an oxide film, consisting of mainly Fe.sub.3 O.sub.4, is formed on the surface of the shadow mask.

Abstract: An antimicrobial substance containing an ethylene copolymer as an active ingredient and an antimicrobial resin composition containing the ethylene copolymer are disclosed. The ethylene copolymer comprises from 40 to 95% by weight of ethylene, from 5 to 60% by weight of at least one dialkylaminoalkylacrylamide comonomer represented by formula (I): ##STR1## wherein R.sub.1 represents a hydrogen atom or a methyl group: R.sub.2 and R.sub.3, which may be the same or different, each represents an alkyl group having from 1 to 4 carbon atoms; and n represents an integer of from 2 to 5, and up to 20% by weight of one or more of other ethylenically unsaturated comonomers, and has a number average molecular weight of from 5,000 to 50,000.

Abstract: Several embodiments of variable camshaft timing means for twin overhead cam engines. There is provided a first timing altering means between the engine output shaft and one of the camshafts and a second timing altering means that is operative between the one camshaft and the other camshaft. Both timing altering means are operated by the same hydraulic pressure in several embodiments and a locking device is incorporated so as to avoid self-induced timing adjustment due to the change in driving loads.

Abstract: A solar battery system characterized by at least one solar cell for converting light energy to electrical energy which is stored in the system is provided. The solar cell is formed of a semiconductor selected from the group consisting of single crystal, polycrystalline and amorphous substrates and is coupled in parallel to an energy-storage capacitor, which capacitor is also connected in parallel with a loading circuit. The capacitor is formed of compressed particles of activated carbon which stores electrical energy charged to it by the solar cell at a selected voltage level. A diode is coupled in series to an output terminal of said solar cell to prevent the flow of a reverse current to the solar cell during discharge of the capacitor to the loading circuit.
