Title: Optical scanner
Inventor: MORI SHUJI
IPC: G02B26/10
Filed: 1988-02-19
Abstract: PURPOSE:To use an inexpensive, small-diameter single ftheta lens by making fine- angle divergent luminous flux incident on a deflector. CONSTITUTION:A light source 1 emits divergent light and a photodetecting element group converts the divergent light emitted by the light source into the fine-angle divergent luminous flux; and the deflector 6 deflects the fine-angle divergent light which is converted by the optical element group and the ftheta lens 7 which has positive refracting power makes an ftheta correction of the scanning luminous flux deflected by the deflector 6 and also converges it on a scanning surface 9. Then an anamorphic optical element 8 converges the scanning converged luminous flux which is passed through the ftheta lens only in a subscanning direction. Consequently, the ftheta lens can be arranged nearby the deflector and while the scanning width on the scanning surface is increased by using the small-diameter ftheta lens with short focal length, the optical scanning device is reduced in size and made inexpensive.

Abstract: PURPOSE:To accurately measure the flow rate of jet which is released and discharged on the way of a duct at one time without virtually partitioning a discharging surface by deciding the flow rate of the jet from the test curve of the blade of a generator combined with electric motor. CONSTITUTION:Pressure in the vicinity of a discharging port before setting an intake port 3 to the discharging port 2 and pressure in the vicinity of the discharging port after setting the port 3 to the port 2 are detected by a pressure sensor 16. Next, pressure difference between them is stored in the memory of a computing element 13 and the lost resistance of the intake port 3 with a flexible expansion pipe 5, which is the cause of fluctuation, is gradually recovered by a resistor 9 by allowing the blade 6 of the generator combined with electric motor 7 to work as an electric motor. The flow rate of the discharging port 2 is calculated from the test curves of ventilating quantity and shaft power by using a value obtained as the output of the electric motor by rotating the blade 6 with jet energy at an initial stage when the intake port 3 is set and the sum of power required to recover the resistance loss of the expansion pipe 5 by rotating the blade 6 as the electric motor.

Title: Device and method for judging deterioration of battery
Inventor: OSHIMA MASAKI
IPC: G01R31/36
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To judge the deterioration of a battery at a high speed by changing a constant current flowing to the battery in a step-like state and measuring the variation of the transient response of the polarization voltage of the battery and, when the variation becomes larger than a specific value, judging that the battery is deteriorated. SOLUTION: The variation of the transient response of the polarization voltage of a battery is measured while a constant current flowing to the battery is changed in a step-like state. When the variation becomes larger than a prefixed specific value, it is judged that the battery is deteriorated. The period of time during which the constant current is made to flow before the current is changed in the step-like state is made, for example, 10 times longer than the measuring time after changing the current. When, for example, a discharge current pulse is set at 0A after the constant current is made to flow for a fixed period of time, the voltage of the battery becomes a waveform (a).  The voltage of the battery immediately after the pulse is set at 0A instantaneously changes by a voltage change (r.I) caused by a pure DC resistance and, thereafter, a voltage change (rη.I) caused by polarization appears. The variation ΔV1 of the polarization voltage which occurs t1 seconds after the discharge current becomes 0A is measured and, when the measured value is larger than the specific value, it is judged that the battery is deteriorated.

Filed: 1983-03-07
Abstract: PURPOSE:To ensure a satisfactory tracking operation by synthesizing an error pattern with a basic pattern which drives a mobile head so that the tracking and sending sections are set symmetrical to each other for the tracking start point. CONSTITUTION:A microcomputer controls a basic pattern PN to secure a smooth connection among A, B, E and F by having a linear tracking section where a video track is tracked like between AB and EF and a smooth video head sending section line between BE. An error pattern EMN(t) is synthesized to the pattern PN to obtain a mobile head driving pattern DN(t). In order to eliminate the generation of a gap at a point where the tracking section changes to the sending section, the pattern EMN(t) is set symmetrical to the next error pattern for the start point S of the next tracking. Thus a smooth connection is secured among A, B, E and F respectively.
