Title: Method of measuring upset quantity of electric seam-welding tube
Inventor: SHINTANI SUSUMU
IPC: G01B21/06
Filed: 1979-06-26
Abstract: PURPOSE: To make it possible to measure the upset quantity of an electric seam- welding tube continuously with a high reliability by continuously measuring the gap between rolls of an ultimate fin pass roll and a gap between squeeze rolls.  
     CONSTITUTION: A gap G 1  between the rolls of an ultimate fin pass roll 4 3  and a gap G 2  between rolls of a squeeze roll 5 are respectively measured continuously during the tube making operation. On the basis of various elements such as these gap values G 1  and G 2  and the hole molds of both rolls 4 and 5, the difference Δl between each part of the peripheral length l 1  of the tube when the tube passes the ultimate fin pass roll 4 3  and the peripheral length l 2  of the tube at the time of passing the squeeze roll 5 is sought. The gap values G 1  and G 2  are supplied succeeding operating machines 8 and 9, and the output value l 1  from the operating machine 8 enters a delay device 10, and supplied in a subtracting unit 12 together with the peripheral length value l 2  after the welding, the subtracting unit 12 calculates the upset quantity Δl by l 2 -l 1 =Δl.

Title: Cylinder injection type engine with supercharger
Inventor: SASAKI JUNZO
IPC: F02D23/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent an air-fuel ratio from exceeding a misfire limit in an extremely low load region while appropriately corresponding to a fuel demand in a high load region when a supercharger is driven. SOLUTION: Fuel is directly injected near an ignition plug 36 by arranging an injector 35 on a nearly circumferential rim part of a combustion chamber 29. Fuel is injected during a latter period of compression stroke in a low load range, and stratified charge combustion is carried out. Or fuel is injected during intake stroke in a high load range, and uniform burning is carried out. In an operating range for carrying out stratified charge combustion, especially in the operating range of an extremely low load at the time of an idling operation and the like, the closing period of an intake valve 32 is delayed largely so as to set an effective compression ratio smaller than an effective expansion ratio to suppress filling of intake.

IPC: G01N27/406
Filed: 1993-03-15
Abstract: PURPOSE:To prevent the degradation of characteristics by using a lithium ion conductive solid electrolyte and a detecting electrode material thereby avoiding influences of the moisture in the air when a sensor is not heated. CONSTITUTION:A lithium ion conductive solid electrolyte 9 mainly composed of Li, Al, Si, O is used for an alkali ion conductive solid electrolyte. Lithium carbonate or a mixture of lithium carbonate and one or a plurality of kinds of alkaline earth metallic carbonate is added to a detecting electrode 8 by 5-50% of the weight of the electrode. The lithium ion conductive solid electrolyte 9 has a considerably small solubility to water, and the amount of lithium ions movable in the electrolyte 9 is enough to work as a sensor. The moisture in the air is hard to influence the sensor. Further, since lithium carbonate has a small solubility to water, the deliquescence is never brought about by the moisture in the air.

Abstract: PURPOSE:To make duration of electrification adjustable simultaneously with the adjustment made at a single place by a method wherein a circuit for selection of pulses and a circuit to control the duration or the electrification are provided, and two kinds of durations (long and short) for the electrification are obtained by delaying the pulses from a single one-shot timer. CONSTITUTION:In the case where a selecting signal (d) emitted from a printer control circuit 5 is of high-level (printing signal), a pulse (a) from an one-shot timer 1 alone passes through a selecting circuit 6, and is supplied to a drive circuit 7 as a pulse (e). Therefore, as a switching transistor 7a is made conductive for a period corresponding to the pulse duration of the pulse (a) with a pulse (g) outputted from an AND circuit 7a, a needle-driven solenoid 7b is electrified for the above-mentioned period with driving voltage VH. In the case where the selecting signal is of low-level, the pulse (e) which is a logical sum of the pulse (a) and a pulse (b) from a delay circuit 2 is supplied from the selecting circuit 6 to the drive circuit 7. Therefore; as the pulse (g) in the pulse duration corresponding to the duration in which the delay time Td in the delay circuit 2 is added to the pulse duration of the pulse (a) is outputted from the AND circuit 7a, the duration of the electrification to the solenoid 7b becomes longer.
