IPC: G06F15/173
Filed: 1989-01-18
Abstract: PURPOSE:To improve the using efficiency of a bus and to facilitate the control of the bus application by reference to the application information by adding this information to each entry to show a specific first cache that uses the corresponding entry. CONSTITUTION:Each of second cache memories SCM 21 and 22 have two entries in a single set, and each entry contains the application information which shows the specific one of first caches FCM 11-14 that uses the relevant entry. In the case both FCM and SCM have the cache mistakes, the entry which is not used by the FCMs except those that had the cache mistakes among those FCMs which share the SCM which had a cache mistake is selected based on the application information. The data on the selected entry is exchanged with another. Thus it is not required to send a flash command to the FCM in reponse to the replacement of the SCM. As a result, the bus application efficiency is improved and the control is faciliated for the bus application.

IPC: G01S7/524
Filed: 1989-01-17
Abstract: PURPOSE:To almost eliminate a dead zone in the vicinity of the ultrasonic detecting device by providing a damping oscillator for generating a damping ultrasonic wave whose period is equal to that of an ultrasonic pulse and whose phase is different by 180 degrees on an ultrasonic emitting means. CONSTITUTION:On an ultrasonic emitting means 1, a damping oscillator 10 is provided in addition to a conventional vibrator 3 and an oscillator 4. On this damping oscillator 10, an automatic switch 11 is provided so that a damping wave Sd is emitted by one pulse from the vibrator 3 continuously from a driving wave S1 so as to oscillate the damping wave Sd whose period is the same as that of the oscillator but whose phase is different by 180 degrees. When the driving wave S1 is emitted to a P point, and subsequently, the damping wave Sd being larger than the driving wave S1 is emitted by one pulse, a voltage-divided wave Sz is generated in a Q point, and as for a reverberation wave S3, both reverberation waves of both the waves S1, Sd interfere with each other and become almost zero. Therefore, the reverberation wave in this case becomes almost zero.

Title: Solid-state image pickup element
Inventor: ODA HIDETSUGU
IPC: H04N5/335
Filed: 1982-01-22
Abstract: PURPOSE:To reudce the value of adverse bias voltage, by forming a partial region of a semiconductor substrate right under a photodiode with a semiconductor region which has the conduction type opposite to a well region and high density of impurity. CONSTITUTION:An n type semiconductor region 22 added with an impurity of high density is formed at a partial region right under a photodiode of an n type semiconductor substrate 21. At the same time, an n type semiconductor layer 23 is formed on the substrate 21 by an epitaxial growing process, for example. Then p wells 2 and 3 are formed on the layer 23, and an n type semiconductor region 5 which forms a photodiode is formed on the well 3. Here if the adverse bias voltage increases, the layer 23 right under the region 25 is completely depleted. Then the edge of the depletion layer finally reaches the region 22. Thus the depletion layer does not extend easily since the region 22 has high density, and the adverse bias voltage contributes to extending the depletion layer toward the well 3. As a result, the adverse bias voltage can modulate effecitvely the potential of the well 3, and the value of the adverse bias voltage is reduced.

Abstract: PURPOSE: To obtain a pulse-width modulation output which can be processed analogically and digitally by a simple mechanical constitution by reducing the number of receiving methods to one as to a displacement position detector using a magnetostrictive delay line.  
     CONSTITUTION: Once a driving pulse is applied 4 to magnetostrictive delay line 1, coil 2 outputs a pulse arriving direct at coil 2, that arriving after reflecting at a right flank once, and that of this pulse after reflecting both flanks of driving delay line 1. The output of coil 2 is supplied to peak detector PD and then differentiated at the timing synchronizing with the reference frequency of oscillator OSC by phase detector circuit PSD and after integration by INT, its output is added to a fine-amplitude modulated-wave signal of oscillator OSC and then supplied to voltage control driving pulse generator VCP. Then, driving method 4 is pulse-driven by the output to exercise control so that the output of phase detection circuit PSD will be zero. Then, a pulse-width-modulated position signal is sent out PWM.

IPC: G01L3/10
Filed: 1993-01-22
Abstract: PURPOSE:To enable the elimination of effect of an external magnetic field in the direction parallel with a torque transmission shaft by forming the torque transmission shaft hollow while a bypass member with the magnetism thereof higher than that of a shaft material of the torque transmission shaft is arranged at the hollow part. CONSTITUTION:A torque transmission shaft 10 is formed hollow and a solid shaft-shaped bypass member 24 which is formed smaller than the diameter of a hollow hole thereof and longer than the transmission shaft is passed through the hollow hole 22. The member 24 employs a material with the magnetism higher than the transmission shaft 10. For example, when nickel molybdenum steel is used for the transmission shaft 10, the material used for the member 24 is permalloy, ferrite or the like. When the torque transmission shaft 10 has a DC magnetic field passing in the direction parallel with the axial center of thereof, a magnetic flux thereof does not reach the surfaces of a magnetically anisotropic parts 12 and 12 bypassing the inside of the bypass member 24 with a stronger magnetism thereby enabling the avoiding of effect of the results of the measurement of torque.

Title: Steering column device
Inventor: HAYASHI KATSUMI
IPC: B62D1/19
Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To provide a low-cost steering column device through simple structure by a method wherein an impact during secondary collision with the steering column device of a passenger occurring due to a frontal clash is sufficiently absorbed by a stroke decreased in absorption of an impact, and a restriction on the design of a steering column is decreased. SOLUTION: In this device, a steering column shaft 5 is mounted on a mounting member 2 on the car body side through a mounting bracket 3. In this case, since a mounting bracket 3 is formed in a quadrilateral link in a side view, in a case of a frontal clash occurring, an impact by a secondary collision transmitted from a passenger to the steering column 5 is absorbed by oscillation of the mounting bracket 3 formed in a quadrilateral link in a side view. Namely, the impact is also absorbed in a direction orthogonal to an axial direction in addition to an axial direction. This constitution sufficiently absorbs a secondary impact from the steering column 5 even when an impact absorption stroke in an axial direction is low.

Filed: 1993-01-22
Abstract: PURPOSE:To carry out the segment replacing work easily and surely by installing a stopper for regulating the revolution range of a pressing piece on the periphery of a slot hole formed on a holder. CONSTITUTION:A pressing piece 11 is turned from the position shown by the full line to the position shown by the supposed line by loosening the tightening bolt 10 of a fixing device 8 fixing a holder 3 on a tool body. Since, at this time, the turn is suspended by a stopper 14 at the release position where the pressing piece 11 turns nearly by 90 deg., each position of the pressing piece 11 and the slot hole 3b on the holder 3 can be allowed to surely coincide. Further, since the pressing piece 11 is energized upwardly by a compression spring, the position change is prevented when a segment is demounted, and the segment can be easily demounted from the tool body. Further, since the opened port of a spring cylinder 12 into which the compression spring 13 is accommodated is closed by the fitting part 11a of the pressing piece 11 also during the replacement of the segment, the trouble that chips, etc., intrude and adhere on the compression spring 13 can be prevented.
