Title: Carburetor
Inventor: KASUYA KAZUSATO
IPC: F02M17/00
Filed: 1980-07-11
Abstract: PURPOSE: To improve atomization within the range of low air rate in such a way that in case where air inlet rate is decreased, fuel is flowed to the auxiliary air path, and in case where the air inlet rate is increased, it is flowed to the main air path.  
     CONSTITUTION: The auxiliary air path 3 is provided so as to be communicated to the main air path 2, and an air valve 5 to open, close and turn in proportion to the pressure derived from the main and auxiliary communicating paths 2, 3 is installed on the upstream side of the main air path 2. Then, a fuel path 24 which has a nozzle 29 saliently provided is positioned at the downstream side of the air valve 5 and it is extended and opened. Thus, since if air inlet rate of a carburetor is decreased, fuel in its most part flows through the auxiliary air path 3, and if the air inlet rate is inreased, most part of fuel flows through the nozzle 29, so that it can improve mixture of fuel and air on the side within the range of low and high air rate.

Title: Manufacture of plate for battery
Inventor: AKOIN EIZOU
IPC: H01M50/536
Filed: 1986-04-24
Abstract: PURPOSE:To easily machine an exposed part of substrate and to form a plate having steady performance without giving any damage to the substrate by cutting a plate obtained by impregnating active material in a conductive substrate made of metal fiber sinter in a specified dimension to form a unit plate, passing the unit plate between knurled rollers to remove active material and to expose the metal fiber sinter for forming a lead fixing part. CONSTITUTION:A plate 1 obtained by impregnating active material in a conductive substrate made of metal fiber sinter is cut in a specified dimension to form a unit plate. The unit plate is passed between knurled rollers 2, 3 having a single step or multiple steps to remove active material and to expose the metal fiber sinter for forming a lead fixing part. Thereby, time required to remove active material is remarkably decreased, and damage to the metal fiber sinter is prevented. Since the active material is completely removed from the substrate, welding strength of a current collecting terminal to the substrate is increased, and the plate having steady performance can be obtained.

IPC: H01P5/107
Filed: 1982-06-03
Abstract: PURPOSE:To attain a microwave converter which has band-pass characteristics and whose characteristics are minutely adjusted easily, by coupling a microstrip line constituted on a dielectric substrate and a waveguide via a dielectric resonator. CONSTITUTION:The waveguide 5 is used in the TE mode and the lateral width of the waveguide 6 is equal to the guide wavelength, which is shorter than the input frequency. The waveguide 6 is coupled with the dielectric substrate 7 provided to a base 11 and the dielectric resonator 8 is arranged around the coupling point on the substrate 7. Further, a movable metallic body 9 adjustable up and down is placed above the resonator 8, and the microstrip line 10 is formed on the substrate 7 near the resonator 8. Electromagnetic waves propagating in the waveguide 5 are interrupted at the waveguide 6 and reach the resonator 8 after exponential attenuation. This energy is strengthened with the resonance phenomenon at the specific frequency of the resonator 8 and coupled in the TEM mode of the line 10 electromagnetically. In this way, the microwave converter which has the band-pass characteristics and whose characteristics are minutely adjusted easily is attained.

Title: Driving system for paper-tensioning mechanism
Inventor: MATSUNAGA ARATA
IPC: B41J15/16
Filed: 1982-06-02
Abstract: PURPOSE:To prevent deformation of a feed hole and staggering of paper from occurring, by controlling the tension of a printing paper in accordance with the thickness of the paper, in a printer having a paper thickness adjusting function. CONSTITUTION:When printing on a thick paper 6P, selecting switches SW1-1 and SW1-2 for the thickness of the printing paper are set on the 6P side. In this case, even when a paper-feeding signal (a) becomes L, a time delay is present until the paper is stopped, so that a timer T6Pis simultaneously started, and when the paper-feeding signal is present after a preset period of time, an AND condition is established, so that a solenoid L is excited to change a pressure exerted on the paper. The exciting voltage is compared with upper and lower limits of the width of a paper thickness voltage V6P by a comparator COM, the voltage is repeatedly raised and lowered within the width, thereby maintaining a pressure (and therefore, tension) according to the thickness of the paper. When the thickness of the paper is reduced, the selecting switches SW1-1, SW1-2 are selected to the 1p side in accordance with the thickness. Thus, the pressing timing and the pressure are controlled in accordance with the thickness of the paper, and deformation of the feed holes and staggering of the paper are prevented from occurring.

Title: Manufacture of magnetic head
Inventor: YASUDA ISAO
IPC: G11B5/127
Filed: 1987-04-17
Abstract: PURPOSE:To improve the reliability of tape run and manufacture a core head of an extremely thin film, by constituting a reinforcing body by shaping a glass layer welded to one side face of a core and removing the work strain after the core is formed to have a prescribed track width. CONSTITUTION:One surface 10a of a core 10 sliced to an appropriate thickness is polished and frit glass 11 is applied to the surface 10a. Then the glass 11 is melted and welded to the core 10 with an appropriate thickness. After the glass-made reinforcing body 11 is welded to the core 10 in such way, the core 10 is shaped to have a prescribed thickness by polishing the core 10 in parallel with the welded surface. Then work strain of the core 10 is removed by heat- treating the core 10 at a temperature lower than the softening temperature of the reinforcing body 11 after the core 10 is shaped to the prescribed thickness by using the reinforcing body 11 as a reference. Since the core 10 does not contain any organic bonding agent which is usually used for joining the reinforcing body 11 to the core 10, reliability at the time of running tapes is improved and, since the thinning work of the core material is carried out under a condition where the core material is reinforced by the glass material, a core head of an extremely thin film can be manufactured.

Title: Wick
Inventor: UNO KATSUHIKO
IPC: F23D3/08
Filed: 1981-06-19
Abstract: PURPOSE:To enable rapid ignition even when the quantity of combustion in a main wick evaporating section is reduced by mounting an auxiliary wick to one part of the main wick and forming a notch section to the main wick evaporating section opposed to the auxiliary wick. CONSTITUTION:Fuel is sucked up to both a main wick and an auxiliary wick 4 when fire is extinguished, but fuel for evaporation is sucked up to the main wick and fuel necessary for ignition to the auxiliary wick 4 completely independently because both are separated by a separating material 5. When combustion, on the other hand, fuel is sucked up to the main wick at all times, but fuel is not sucked up to the auxiliary wick 4 because it is separated to the upper section of a fuel surface. Since the width of the notch section 6 is slightly larger than that of the auxiliary wick 4 and the evaporating section 1 and the auxiliary wick 4 are not contacted, fuel sucked up to the auxiliary wick 4 when the fire is extinguished is burnt out after ignition, the wick 4 is brought to a non-fuel combustion condition during stationary combustion, tar is not stored and the characteristic of ignition is not degraded.

Title: Facsimile transmission system
Inventor: TAKAHASHI YUTAKA
IPC: H04L29/08
Filed: 1985-05-08
Abstract: PURPOSE:To cope with a reception error in memory reception by replying a reception error to a transmitter and deleting a picture from a picture memory when the retransmission of the said picture is notified from the transmitter. CONSTITUTION:When picture information PIX is received by a receiver RX and it is discriminated that many errors take place in the receiver RX, a procedure end signal EOP is sent from the transmitter TX to the receiver RX and the receiver RX sends a retrain NOT signal RTN as a reply. In receiving the signal RTN from the receiver RX, the transmitter TX outputs a non-standard equipment setting signal NSS2 to inform the retransmission of the picture information to the receiver RX. Thus, receiver RX deletes the picture signal received just before the storage in the picture memory from the picture memory so as to ensure the storage area usable for the picture memory.
