Patent JP-H01229905-A (JP)
Title: Displacement detector
Inventor: ICHIKAWA SOJI
IPC: G01D5/244
Filed: 1988-03-10
Abstract: PURPOSE:To make it possible to detect the amount of relative displacement at an absolute position from a small number of analog signals, by providing a main scale, an index scale, etc. CONSTITUTION:An illuminating light passing through an index scale 30 is incident upon a main scale 10 provided with scales. Four tracks are formed in the scale 10. The illuminating light passing through the scale 10 is ejected, corresponding to grids 42, 44, 46, 48 of the scale 230, into photoreceptors 60A, 60B, 62A, 62B, 64A, 64B, 66A, 66B provided, for example, by two for every track. In accordance with the relative movement of these scales 30 and 10, a sine wave signal of two phases is obtained from each track, having a phase 90 deg. different from each other. An output of each photoreceptor is inputted to an absolute displacement detecting circuit via respective preamplifier. Thus, the absolute position can be detected on the basis of analog signals. Even when a detecting error occurs, it does not lead to a large error in the measurement.

Abstract: PURPOSE:To enable to prevent occurrence of vapor-lock, by providing a delivery pipe formed therein with a fuel supply passage for supplying fuel to an inlet port of a fuel injection valve and a discharge passage for discharging fuel from an outlet port of the fuel injection valve. CONSTITUTION:Fuel, pressure of which is controlled to a relatively low level by a pressure regulating valve 4, is passed through the inside of an injection valve 1 from an inlet port 20 to an outlet port 22 via a chamber 24 and a portion of the fuel is ejected from an orifice when current is supplied to an electromagnetic coil 12. This injection valve 1 tends to receive heat from an engine and therefore to produce fuel vapor on the inside of the same. However, since fuel is circulated from the inlet 20 to outlet 22, fuel vapor thus produced is discharged to a tank by the above fuel flow through the outlet port 22, an outlet port 32a and a discharge passage 32 of a delivery pipe 3, and the pressure regulating valve 4. Thus, the pipe 3 has a fuel supply passage 30 and the fuel discharge passage 32 formed therein, its structure can be simplified and the pipe connecting operation is rendered easy. Thus, it is enabled to prevent occurrence of vapor-lock.

Title: Positioning control system
Inventor: HASHIMOTO SHUICHI
IPC: G11B21/08
Filed: 1990-03-12
Abstract: PURPOSE:To prevent a seek time-out error occurring by performing such control that the travel speed of a head part when a re-zero operation is performed can be set as preset targeted speed. CONSTITUTION:When the re-zero operation is performed, a driving signal in accordance with the preset targeted speed set at a control part 4 is added on a driving part 3, and the head part 2 is moved at high speed to a targeted track 0. At this time, the gap of a track crossing pulse after the lapse of a time when the travel speed of the head part 2 can be kept constant is measured, and it is compared with the gap of the track crossing pulse in accordance with the preset targeted speed. Since the difference of pulse gaps shows the difference between the actual speed of the head part 2 and the preset targeted speed, it is possible to make the travel speed of the head part 2 approach originally preset targeted speed by re-setting the targeted speed and increasing speed difference.
