Title: Phase shift circuit
Inventor: AMAMOTO TORU
IPC: H03H11/18
Filed: 1985-12-07
Abstract: PURPOSE:To shift accurately an input signal by 90 deg. and to make the circuit suitable for circuit integration by setting the 1st, 2nd and 3rd resistors in response to the phase shift quantity so as to eliminate a DC bias cut-off capacitor. CONSTITUTION:Output terminals A, B of the 1st and 2nd signal voltage sources 12, 16 are connected through a series circuit comprising resistors R6, R7, and a connecting point C between the resistors R6 and R7 is connected to a base of a transistor (TR) Q1 of a differential amplifier circuit 13. A difference voltage of collector voltages extracted from Trs Q1, Q2 becomes a signal whose phase is shifted from that of an emitter AC voltage v' of a TR Q3 by 90 deg.. That is, a frequency signal generated by the 1st signal voltage source 12 is shifted by 90 deg. and outputted from output terminals 14, 15. Since the phase shift circuit uses no DC bias cut-off capacitor, an accurate phase shift is applied and the circuit is suitable for circuit integration.

That is, from each mass peak displayed at the upper part of the screen, the mass having a change can be found, and on the central part of the screen, the total value of the selected mass peak is displayed in a time axis. The both parts are made to respond to the change of the mass peak value. At the lowermost part of the screen, one mass peak value is displayed in a time axis, and the time response of the most noticeable mass can be found. Consequently, the total ions and the spectrum can be monitored at a real time simultaneously.

Title: Solenoid type fuel injection valve
Inventor: KAMITSUMA YASUO
IPC: C23C22/00
Filed: 1987-11-04
Abstract: PURPOSE:To enhance the anti-wear and anti-shock properties by forming a single-phase or mixed layer of oxides due to oxidative processing on at least one of the collision surfaces of plunger and core. CONSTITUTION:When a solenoid 3 is energized, a plunger 2 is attracted upward, and a gap is generated between a ball 9 and a seal 7 followed by injection of the fuel. The size of this gap is determined by the distance 19 between the bottom surface 17 of a core 5 and the top surface 18 of the plunger 2, and when iterative collisions of the core 5 with plunger 2 at the opening and closing time of the injection valve causes wear and a change in the distance 19, the amount of fuel injection changes secularly. To prevent it, hot oxidative processing is applied to at least one of the collision surfaces. Because the oxide film 22 has a high hardness and is thicker with higher processing temp. and longer processing time, an appropriately formed thickness enables adsorption of the fuel oil to voids existing in the oxide film 22, which relieves shock load due to damping effect, and these synergetic effect enhances the anti-wear, anti- shock, and anti-corrosive properties.
