Title: Hydroplane detector
Inventor: IWATA TORU
IPC: B60W10/188
Filed: 1991-10-17
Abstract: PURPOSE:To detect a hydroplane state accurately by installing a hydroplane detecting means which calculates a difference between a driven wheel speed filter value and a driven wheel sensor value, and detects that it is the hydroplane state when the difference is more than the specified value. CONSTITUTION:Right front-wheel sped sensor value VWFR out of a right front- wheel sensor 1 and left front-wheel speed sensor value VWFL out of a left front- wheel speed sensor 2 are subjected to a low-pass filter with the specified cut-off frequency, setting them down to right front-wheel speed filter value FVWFR and left front-wheel speed filter value FVWFL each (50). In a hydroplane detector which detects a hydroplane state being produced by a water filmlying between a tire and a road surface at the time of running, a difference between the controlling front-wheel speed filter value FVWFR (FVWFL) and the front-wheel speed value VWFR (VWFL) is calculated. When the difference is more than the setting value V0, it is so detected as the hydroplane state. When rushing into this hydroplane state, detection takes place extending over the whole area ranging from inrush to escape.

Title: Dust collector
Inventor: TAKANO HARUO
IPC: B01D46/02
Filed: 1985-11-30
Abstract: PURPOSE:To obtain the titled device capable of simply shaking off even a sticky powder, by providing a scattering port for applying a non-sticky precoat powder to the surface of the dust collection chamber side of a filter. CONSTITUTION:Air in a purifying chamber 7 is sucked by a suction blower 21 and a precoat powder is supplied to a precoat powder chamber 6 by a powder feeder 26 through a pipeline 27. This precoat powder is uniformly scattered to the entire periphery of a filter 11 in a dust collection chamber 5 from a scattering port 16 by the flow of recirculated air to precoat the filter 11. Therefore, sticky dust sucked in the dust collection chamber 5 is adhered to the precoat powder and prevented from directly adhering to the filter 11. Therefore, when a jet pulse is applied to the filter 11 from the side of a purifying chamber, 7 the sticky dust can be simply shaken off along with the precoat powder.

Title: Device and method for separating package
Inventor: TSUKUSHI TOSHITAME
IPC: B26D1/06
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To provide a package separating device which can reliably separate a BGA package from a tape carrier by cutting and easily deal with the change of the dimensions of the BGA package. SOLUTION: An upper blade moves in a vertical direction. A lower blade 12 moves in a direction orthogonal to the direction of extension of an upper blade 11, and its length which abuts the upper blade 11 struck down is varied. And, a pair of upper blade and lower base cut both transversal sides of a BGA package to be cut. On the other hand, another pair of upper blade and lower base cut both longitudinal sides of the BGA package. Thus, an inexpensive device easily and reliably cuts off the BGA package from a tape carrier. Further, by a simple operation which only moves the lower base, a cut length L is varied so that it is possible to deal with the cutting-off of BGA packages of different sizes.

Title: Operation controller for receiver
Inventor: TANAKA OSAMU
IPC: H04B1/16
Filed: 1986-11-13
Abstract: PURPOSE:To improve the convenient use of a receiver while reducing the power consumption of the receiver by keeping the receiver in the reception state during a predetermined time and operating the receiver intermittently in a way of repeating the reception state and pause state alternately. CONSTITUTION:In closing a power switch 26, an output of an oscillation section 18 controls a constant voltage power section 20 through an OR gate 17. When a radio wave is received while an output of the constant voltage power section 20 is set, an output of a rectifier section 16 goes to a high level and an output of the section 20 is set through the OR 17, then the power voltage is supplied to each section independently of the output of the oscillation section 18 during the reception of radio wave. A timer section 19 gives an output for a predetermined time only to keep the section 20 turned on for the time. When a time preset to the timer 19 elapses, the power section 20 repeats ON/OFF corresponding to the output of the oscillation section 18.

Abstract: PURPOSE:To enable continuing a normal recording even when the clogging of a head is generated by detecting the clogging with a simple constitution. CONSTITUTION:A clogging detecting signal (d) is written in a certain track by a recording and reproducing head 14. The recording and reproducing head 14 reads out a detection pulse (d') including the clogging detecting pulse (d) during scanning adjacent tracks. The detection pulse is compared with a threshold value by a comparator 58 included in a clogging detecting circuit 30 and it is judged that the clogging is not generated in the head 14 when the detection value is larger than the threshold value and it is judged that the clogging is generated in the head when the detection value is smaller than the threshold value. A detection pulse (h) of a high level is supplied to a counter 62 and then a head changing over switch 46 selects a replacement head 16 by the control of a channel selector 66. That is, the recording and reproducing head 14 is changed over to the replacing head 16.
