Title: Sewing machine for holing
Inventor: KOIE KAZUAKI
IPC: D05B37/02
Filed: 1990-10-08
Abstract: PURPOSE:To easily switch the front scalpel method and rear scalpel method with no troublesome work by providing a needle swing width changing means setting the needle swing width by a needlebar sway system when the rear scalpel method is selected by a selecting switch smaller than when the front scalpel method is selected. CONSTITUTION:Sewing in the rear scalpel method is perfofmed while the needle swing width is set smaller than in the front scalpel method, thus the sewing work in both methods can be performed while a feed bar 24 is operated in common. A needle swing pulse motor 35 is provided as an independent drive source, the needle swing width can be changed by only changing the excitation quantity of the needle swing pulse motor 35 without requiring troublesome adjusting work unlike the structure to convert the rotation of a main spindle into the sway of a needlebar. The sewing work in both methods can be automatically performed by only changing the excitation quantity of the needle swing pulse motor 35 based on the selection of a selecting switch 9. A user can switch the front scalpel method and the rear scalpel method very easily by only operating the selecting switch 9.

Title: Misfire deciding method for gas heat pump air-conditioner engine and control method therefor
Inventor: TAKAMATSU MASAKI
IPC: F02D19/02
Filed: 1994-10-12
Abstract: PURPOSE: To decide that a misfire occurs when the variation width of the number of revolutions is low and to prevent an air-fuel ratio from changing into the fuel rich side by deciding that a misfire occurs when the average value of differences between the moving average value of the numbers of revolutions of an engine and the actual number of revolutions exceeds a set value. CONSTITUTION: The portion situated upper stream of a fuel gas feed route 1 to an engine 21 is connected to a fuel gas feed source through a pressure control valve 9 and a plurality of on-off valves 10. During steady operation wherein the load of the engine 21 is low, a flow rate of a fuel gas fed to the engine 21 through a first route 4 having a nozzle 3 is controlled by a control device 12. During starting and acceleration wherein the load of the engine 21 is high, a flow rate of a fuel gas fed to the engine 21 through a second route 5 having a flow rate control valve 6 is controlled thereby. In this case, when the average value of differences between the moving average value of the numbers of revolutions of an engine and the actual number of revolutions exceeds a set value, it is decided that a misfire occurs.  Thus, in a case the change width of the number of revolutions is low, the occurrence of a misfire is decided.

Title: Method and apparatus for dehydrating fluidic earth and sand
Inventor: KINOSHITA KIICHI
IPC: B01D29/25
Filed: 1985-12-03
Abstract: PURPOSE:To solve such a problem that the treatment cost of surplus soil is increased in the tunnel drilling construction by providing a water-passing hole to one part of the pipe wall of a forced-feed pipe wherein fluidic earth and sand are sent under pressure therein. CONSTITUTION:Many water-passing holes 5 are formed around a pipe in one part of a forced-feed pipe 1. Therefore when sending fluidic earth and sand under pressure through the forced-feed pipe 1, these are flowed while muddy water is distributed in a pipe wall side and grits are distributed in a pipe axis side. In such a case that fluidic earth and sand are passed through the water- passing holes 5 of the forced-feed pipe 1, fluidic earth and sand can effectively dehydrated by extruding muddy water through the holes 5. Therefore since dehydration can be performed while continuing the sending under pressure in the forced-feed pipe of fluidic earth and sand, operation efficiency is high and furthermore, use of a conventional dehydration agent is not necessitated. Even if using the dehydrating agent, the usage of the dehydrating agent is a small quantity because the dehydration of appropriate amount is performed before hand and the cost for dehydration can be reduced.

Filed: 1985-12-03
Abstract: PURPOSE:To increase energy density and lengthen the life by retaining electrolyte in the part below a plate group in high concentration as it is and making electrolyte in the part above the lower end of the plate group uniform. CONSTITUTION:When electrolyte concentration is decreased with proceeding of discharge, terminal voltage is lowered. By detecting electrolyte concentration decreased below a specified value, a large volume of air is supplied through a pipe 7 and allowed to bubble from holes A and B. Therefore, high concentration electrolyte 3 in the part below a plate group 1 is stirred and reaches the plate group 1 and utilized in discharge reaction. In charge, the electrolyte 3 is stratified and concentration of the lower part thereof goes higher. On the way of charge or in the final stage of charge, a small amount of air is supplied through the pipe 7 and allowed to bubble from only the hole B. Thereby, the electrolyte 3 in the part above the lower end of the plate group 1 is stirred to go uniform concentration. The electrolyte 3 below the plate group is retained in high concentration as it is.

Abstract: PURPOSE:To suppress feeling of unpleasantness due to noises of a sent voice by discriminating whether an input signal fed from a microphone is a voice or a noise, generating a level output in response to the noise level and adjusting the level of the input signal in response to the level output. CONSTITUTION:The voice at the transmission side and the surrounding noise enter the microphone 4 of a handset 2 and is fed to a transmission system 6. The signal fed to the system 6 is fed to an attenuator 34 and to a signal discriminating circuit 10, which discriminates whether the input signal is a voice or a noise and generates a level output in response to the noise level and gives it to the circuit 34.

Abstract: PURPOSE:To miniaturize a high frequency use thin film transformer and improve the performance by suppressing inductance reduction and the rapid increase of high frequency conductor resistance and improving the coupling between primary and secondary conductors. CONSTITUTION:Top and bottom magnetic layers 8 and 14 are connected at a through hole 15 and a primary and a secondary conductors 10 and 12 are permitted to be covered vertically and horizontally in the longitudinal direction by a magnetic body which has a closed magnetic circuit.
