Title: Camma ray measuring instrument
Inventor: KASAI SHOZO
IPC: G01F23/00
Filed: 1992-10-29
Abstract: PURPOSE:To provide a gamma-ray measuring instrument of enhanced measuring accuracy which is less affected by ambient temperature changes, provides reduced noise, is easy to manage and can accurately cope with the change of a subject for measurement. CONSTITUTION:The pulse width and wave height of a pulse generator 18 are both adjustable. Pulse signals from the pulse generator 18 are fed to a light- emitting diode 17 via a temperature compensation circuit 19. The light-emitting diode 17 emits light according to the pulse signals fed thereto. The light emitted from the light-emitting diode 17 impinges on a photomultiplier tube 6, together with a gamma ray and plastic scintillator light. Both optical signals are amplified by an amplifier 10 and the pulses transmitted through a comparator 11 are computed using a computing element 12 and converted into level signals. Both of the optical signals fed to a time constant circuit 20 are attenuated by a CR circuit and a light-emitting diode optical signal and a plastic scintillator signal are separated from each other basing on pulse widths.

Title: Tracking device
Inventor: ROBAATO EMU JIYOOJI
IPC: G11B7/09
Filed: 1993-11-22
Abstract: PURPOSE: To prevent the generation of a track jumping phenomenon which occurs in a defective recording medium by monitoring a tracking error signal and generating an abnormality detection signal when the signal exceeds a prescribed threshold. CONSTITUTION: First and second threshold detectors 47 and 49 comparing the tracking error signal supplied from an information reproduction device through a line 51 with a pair of thresholds are provided. The detector 47 compares the error signal with the positive threshold V<+> . The value V<+> is set in a first potentiometer 53. The detector 49 compares the error signal with the engative threshold V<-> . The value V<-> is set in a second potentiometer 55. Both detector outputs are OR-connected by a diode 57 and a tracking loop non-operation signal connected to the gate terminal of an FET switch through a line 59 is formed. Thus, the non-operation signal is generated when the tracking error signal is larger than the threshold V<+> , or smaller than the threshold V<-> . Consequently, the track jumping over phonomenon can be avoided.

Title: Method for controlling freewheel hub mechanism
Inventor: SUGIMOTO TAKUSHI
IPC: B60K23/08
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To surely switch driven wheels to a locked condition by applying a free wheel hub mechanism control method to a four-wheel drive vehicle equipped with an engine in which four-wheel drive side inlet pipe negative pressure that holds the driven wheels locked requires time to reach a switch- guaranteeing negative pressure value and to avoid the error of judging that trouble has occurred in a negative pressure passage through which the four- wheel drive side inlet pipe negative pressure is introduced into a freewheel hub mechanism. SOLUTION: If four-wheel drive side inlet pipe negative pressure, within a set elapsed time when a transfer is switched to four-wheel drive by a two-to- four switch mechanism, does not reach a switch-guaranteeing negative pressure value at which driven wheels are held locked, a four-wheel drive side negative pressure selector valve is actuated so that the four-wheel drive side inlet pipe negative pressure is introduced into a freewheel hub mechanism for a set introduction time at the elapse of every predetermined time interval. Also, control is performed to determine whether or not the four-wheel drive side inlet pipe negative pressure has reached the switch-guaranteeing negative pressure value.
