IPC: A61G7/05
Filed: 1989-01-23
Abstract: PURPOSE:To provide a valve to ordinarily close a blowhole for each blowhole and to prevent the leakage of air when a human being is not lying on the subject mat by providing the valve, which closes by internal air pressure and opens when pressing force is applied from an external part, for each blowhole. CONSTITUTION:Valves a1, a2, a5, and a6 are valves under a blowhole closing state. When the human being is not lying on the mat, and only a light sheet or blanket is placed on the mat, all the valves close in this manner. When the human being lies on the mat, and a human body 4 is laid on the mat, pressure transmitting bars 6 of valves a3 and a4 push shutoff valve parts 5 of the valves downward by the pressure. Consequently, blowholes are opened. At this time, the internal air flows out through the blowholes opened by the valves a3 and a4, dries the human body 4, and is caused to blow out to the external part.

Title: Joint mechanism and universal arm device using same
Inventor: HATA MASAHIKO
IPC: F16C11/04
Filed: 1994-01-07
Abstract: PURPOSE:To provide a joint mechanism capable of freely changing a hinge angle even if a remarkably heavy article is fitted to a movable arm tip, and of strongly holding the hinge angle by rigidity once an arm is stopped. CONSTITUTION:Since incompressible fluid is enclosed inside a cylinder 17, rotating members 2, 3 cannot be turned relatively with application of energizing force. When opening/closing members 21, 22 are opened, the fluid is moved between divisions 25, 26 by the energizing force and a piston 18 and a piston rod 24 are moved inside the cylinder 17, thus starting the relative turning of the rotating members 2, 3. When the opening/closing members 21, 22 are closed, the movement of the incompressible fluid is inhibited. Consequently, the enclosed incompressible fluid does not allow the relative movement between the piston 18 and the cylinder 17 at all.

Title: Magnetic tape recording and reproducing device
Inventor: ISHII TOSHIO
IPC: G11B20/18
Filed: 1989-01-20
Abstract: PURPOSE:To prevent a picture from being disturbed by detecting an error rate of a picture data and reproducing the previous picture. CONSTITUTION:An error flag EFL is outputted by a regenerative signal processing part 2 to a control part 4 when an error rate of a digital signal d1 becomes wrong. Upon receipt of the flag EFL, when a picture memory B 9 is under the recording state, the digital signal d1 of a video signal by one field is not outputted, and changeover switches 3, 6, 7 and 10 are not changed even when a picture input flag FL1 is received. Then, the signal d1 by next one field is continuously recorded in the memory B 9, and the same picture is outputted again from the other memory A 8. In the case of no flag EFL, the switches 3, 6, 7 and 10 are changed to return the initial state. The signal d1 is recorded to the memory A 8, and also a clock CK2 from an oscillation circuit 5 is given to the memory B 9 via terminals 72 and 73 to output a digital signal d3, and then an analog video signal is outputted from a D/A conversion circuit 11. By this method, a beautiful still picture is always reproduced, and hence the picture can be prevented from being disturbed.
