Title: Road surface freezing prediction method
Inventor: YODOGAWA MINOSUKE
IPC: G08G1/00
Filed: 1993-04-15
Abstract: PURPOSE:To accurately predict the status where rain or snow remaining on a road surface freezes by extracting a pattern which is most similar to the actual change pattern out of the change patterns of road surface temperature classified from the measurement for past several years. CONSTITUTION:A road surface freezing detection device 1 measures water, road surface temperature, and atmospheric temperature without any contact to the road surface and then outputs four states (a signal S1) of drying, wetting, freezing, and snowing, road surface temperature (a signal S2), and temperature (a signal S3). A communication control device 2 transmits the output signal to a modulation/demodulation device 3. The transmitted data are processed by a data processing device 7 via a signal reception device 6 and at the same time are input as database. The road surface temperature for the past several years is measured by this method and the change patterns are classified. Then, the actual change patterns from a preset time to a prediction time are obtained and a change pattern which is most similar to the actual change pattern is extracted from the classified change pattern. The freezing on the road surface is predicted based on it.

IPC: H04B7/00
Filed: 1991-04-17
Abstract: PURPOSE:To enable effective data transfer by considering the difference of data transfer capability of respective frequency bands in radio communication. CONSTITUTION:When printing data are inputted to an external interface part 102, a central processing unit 104 recognizes priorities. When it recognizes that the data has high priority, it specifies commands to a data conversion device 105 and a frequency band selection device 107 and controls a data transmitter/receiver 106. The device 106 informs the central processing unit 104 through the device 5 of the state of commanded frequency band. The central processing unit 104 checks data transfer channels for an unused frequency band, and when it is found, selects the data transfer channel. Then the unit 104 controls the device 106, transmits the data showing the data transfer channel to be used to a printing part 110 and transfers the data. When the unit 104 recognizes that the inputted printing data has low priority, the frequency band is retrieved in order from the one having lowest data transfer capability and conducts the similar processing.

Title: Vibration tester
Inventor: HIBINO MANABU
IPC: G01M7/02
Filed: 1978-09-13
Abstract: PURPOSE: To make it possible to determine the intrinsic frequency of a tester for any vibration within a certain range and to make resonance to any frequency thereby to effect the high acceleration by steplessly changing the length of a leaf spring.  
     CONSTITUTION: A leaf spring 6 is clamped in any position by means of a restricting frame 7, and this frame 7 and a vibrating table 10 are connected through a restricting link 8. Thus, the restricting frame, restricting link and vibrating table are made into an integral structure. As a result, the portion of the spring 6 below the restricting frame 7 does not partipate in the vibration amplifying operation, but the portion above the frame 7 becomes effective as the spring. Thus, the vibrating table 10 is vibrated with the intrinsic frequency of the vibrating system having the total weight of the effective portion of the spring 6, a table and a test piece 1 so that resonating phenomana can be established. Thus, by varying the effective length of the leaf spring 6, the intrinsic frequency of the system can be changed.

IPC: G11B21/02
Filed: 1989-05-02
Abstract: PURPOSE:To precisely suppress vibration generated in the movable part of a linear motor even when a focusing actuator or a tracking actuator is operated by mounting a weight on at least either an optical head or a movable member via an elastic member. CONSTITUTION:The weights 17a and 17b are mounted on either or both the optical head and the movable member via the elastic members 18a and 18b. Also, it is recommended to mount the weights 17a and 17b in such a way that their mounting planes can be mounted so as to intersect orthogonally to each other. Therefore, the weights 17a and 17b mounted via the elastic members 18a and 18b can function as vibration absorbers even when the vibration occurs at the time of operating the tracking actuator or the focusing actuator. Thereby, it is possible to sufficiently suppress the vibration in the movable part of the linear motor and to realize a stable positioning operation.

Filed: 1985-05-28
Abstract: PURPOSE:To prevent the sending of a radio wave against rules due to a malfunction at transmission by providing four detection points at transmission OFF/ON as an alarm output point and operation limit point so as to eliminate the contradiction that an alarm is raised at transmission ON regardless of non-output of alarm at transmission OFF. CONSTITUTION:When the power voltage of a battery drop up to a point (c) at transmission ON time A, it is regarded as the operation limit point and the operation is stopped after that time. When the voltage of battery drops to a point (d) at transmission OFF time B, since the operating limit point is lowered clearly with the transmission ON, the operation is stopped at the point (d). Further, the alarm is raised at the point (a) and the near state of the opera tion limit point is informed to the user. Further, all detection points (shown in a-d) are not ways used depending on the characteristic of the battery. For example, when a battery has no potential difference between the points (b) and (d), one point can be omitted.
