Title: Production of connecting rods
Inventor: ITADAKI TOYOKI
IPC: C22C33/02
Filed: 1979-05-22
Abstract: PURPOSE: To obtain the connecting rods which withstand high load by subjecting cast iron chips to grinding and decarbonization and compression-molding this then subjecting this to sintering or/and heat-forging.  
     CONSTITUTION: The chips produced by turning or grinding of cast iron moldings are pulverized and are moved of fine particle powder containing free graphite particles and free carbon by a centrifugal separator (for example, cyclone), whereby the decarbonized cast iron powder of less carbon contents is obtained. This is compression-molded by dies and powder-molding press to the molding resembling to the product. This is annealed or/and heat-forged in a reducing atmosphere such as AX gas to be made into the steel structure containing spheroidized graphite or carbide. After cooling, this is subjected to finishing. This yields the connecting rods having the strength to withstand high load and of good dimensional accuracy and weight balance accuracy. It is also possible to add heat treatment (for example, austempering) to the above-mentioned process.

The MgO layer 10 and the electrode layer 11 are then partly etched in a part of the region in accordance with the electrode pattern to form the waveguide pattern A. Finally, the MgO layer 10 is thermally diffused for about 10hr at about 900 deg.C to form the channel type light guide B. The edge of the electrode is thereby formed flush with the edge of the channel type light guide.

Title: Pulse edge extension circuit
Inventor: MIZUTANI KIYOSHI
IPC: H04N5/93
Filed: 1989-03-15
Abstract: PURPOSE:To suppress the increase of the number of elements, current consumption and the area on the layout of an IC by impressing a reference potential depending on the DC level of an input FM demodulation signal to the base of a transistor and connecting the potential through a resistor to the emitter of a transistor in an amplifier circuit. CONSTITUTION:The input signal inputted from a signal input terminal 1 is impressed to the base of a transistor Q1 in an amplifier circuit 2. When the potential of the input signal is higher in comparison with a reference voltage V1 depending on the DC level of the input signal, a transistor Q2 in an extension circuit 3-a is not operated. When the potential of the input signal is lower in comparison with the reference voltage V1, the transistor Q2 in the extension circuit 3-a is operated and an emitter current flows through a resistor R1 to the amplifier circuit 2. Accordingly, since an output signal is extended, the peak level of an edge part is extended. Thus, the extension circuit can be formed by only adding one transistor and one resistor respectively.

Abstract: PURPOSE:To prevent a natural leaf under conveyance from dislocation by forming each of pallets for a leaf in each set of pallets in radially ascending tiers with the center between pallets for food in the same set of pallets as the radial center. CONSTITUTION:A conveyor is driven intermittently. At an upstream section in the conveyor line, food X is loaded on two pallets 3a, 3b for food in each set of pallets, and a natural leaf Z is loaded on four pallets 4a - 4d for a leaf in the same set of pallets.

In the above process, the temperature of hot air fed to the treating chamber is controlled with the heater 18 of the air conditioner 5 so as to keep the temperature difference between the atmosphere and the fruit within the range between the preset upper limit t 1  and the preset lower limit t 2 . The temperature of the hot air is raised slowly keeping the above condition until the temperature of the fruit reaches the target value T. Thereafter, active heating is not necessary, and heated and humidified air having a temperature nearly equal to that of the fruit is supplied intermittently to the treating chamber to compensate the heat dissipation loss.

Filed: 1990-03-13
Abstract: PURPOSE:To suppress the generation of NOx by burning a gas-rich mixture gas jetted out of a first flame hole in the combustion section for first stage combustion with oxygen shortage and, next, discharging from a second flame hole the unburned gas with excess secondary air in order to carry out two-stage combustion with oxygen in excess. CONSTITUTION:Most part of a mixture gas that is mixed in a channel 6 forms the main flames by burning in main flame holes 11, and the rest of the mixture gas rises from side flame holes 12 between the outer side faces of flat device body 5 and flame holding plates 13 and burns to form side flames. Further, part of the unburned gas burns by secondary air in a combustion chamber 14. With this arrangement by the combustion at the first flame holes in the combustion section 14 the primary stage combustion is made with oxygen shortage. The rest of the unburned gas that does not burn in the combustion section 14 and the combustion exhaust gas are discharged from second flame holes 16 as well with the secondary air through a secondary air passage 9 to form an air-rich rarefied flame 23 and secondary combustion is made. In this way a gas burner 2 makes two-stage combustion, and at the same time it carries out thick and thin combustions and it is capable of suppressing the amount of the generated NOx.
