Title: Phase-locked loop tuner channel selection device
Inventor: MAKINO HIDEO
IPC: H04N5/44
Filed: 1992-02-24
Abstract: PURPOSE:To shorten a synchronization time and project an excellent image on a screen immediately even if a broadcasting station whose frequency center value deviates from a prescribed value is selected by storing the value of the frequency division ratio of the channel at the same time in channel presetting operation together with the channel number. CONSTITUTION:With a command from a CPU 31 by a preset signal, a synchronism detecting means 34 detects the loop state of a phase-locked loop tuner part 32 and sends an active signal to the CPU 31 when the state is in a phase- locked loop. An AFT detecting means 35 detects whether or not the frequency of the phase-locked loop tuner part 32 is tuned to the frequency of the selected broadcasting station, and the frequency division ratio outputted to the phase- locked loop tuner part 32 is transferred by the transfer means of the CPU 31 together with the channel number and stored in a memory circuit 33. The frequency division ratio which is actually tuned to the broadcasting wave is stored and when a user selects the channel, the phase-locked loop is started from the frequency division ratio, so the time up to the tuning is minimized.

Title: Power steering device
Inventor: HAGA KYOSUKE
IPC: B62D5/083
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent a driver from feeling a steering wheel heavy suddenly because of assist failure caused by insufficient flow rate to a power cylinder by fitting a check valve which permits only flow passage in the direction toward the supply passage side from the discharge passage side in a bypath passage. SOLUTION: The first check valve 31 is opened by a rise in the internal pressure of an exhaust passage 27. The hydraulic oil discharged from a right oil chamber 12B is bypassed to the supply passage 22 side by a bypath passage 30 through the first check valve 31, and is flown into the left oil chamber 12A of a power cylinder 12 from a variable restriction V1 whose restriction area increases to eliminate insufficient flow rate to the power cylinder. At this time, a rise in internal pressure stops the second check valve 32, therefore, the hydraulic oil bypassed to the supply passage 22 side from the bypath passage 30 does not flow to a hydraulic hose 21, but is spent for supply to the left oil chamber 12A completely. It is thus possible to eliminate insufficient flow rate to the power cylinder.

Title: Soil conditioner
IPC: C05G3/80
Filed: 1992-03-30
Abstract: PURPOSE:To obtain a soil conditioner which does not deteriorate the gas passability and water permeability of soil when mixed therewith and is desirable for the cultivation of plants by softening and contracting grinds of a closed-cell thermoplastic resin foam by heat of friction. CONSTITUTION:This soil conditioner is prepared by contracting grinds of a closed-cell thermoplastic resin foam by heat of friction to such an extent that at least part of the grinds still retain their original shapes, has irregularities on the surface and still retains closed cells. By forming a water retention layer on the surface, the water retention of this conditioner can be improved. In preparing this conditioner, grinds of a thermoplastic resin foam are contracted to a bulk specific gravity of 0.2-0.8, stuck to each other through their surfaces softened by heat of friction, and bound together by cooling to form surface irregularities. Because this conditioner has a bulk specific gravity higher than the conventional ones and surface irregularities, it is well compatibilized with soil and is difficultly separated from soil when mixed therewith.
