Title: Air cell used for mat for preventing bedsore
Inventor: KASHIWADA TAKESHI
IPC: A47C27/10
Filed: 1992-05-11
Abstract: PURPOSE:To improve an effect of preventing a bedsore by automatically causing a patient to roll over his side without degrading his feeling in the bed by forming air cells to a plane truncated cone shape and forming the width of the air chambers at one end smaller the nearer toward the other end. CONSTITUTION:A mat A consists of a flat base part sheet 10 and plural pieces of the air cells 12 provided freely attachably and detachably adjacent in its crossing direction. The air cells 12 are formed with the slender air chambers 13 and are formed to the plane truncated cone shape. Connecting ports which are freely connectable to air supply tubes are provided at the ends thereof. The width at the larger ends 12c of the air cells 12 is set at 1.5 to 4 times the width of the finest parts 12d. The air cells 12 are formed of the composite materials having rubber and soft PVC layers on the inner layers and cloth layers in the outer layers. The many air cells 12 are segmented to two systems 12a, 12b by making every other system the same. These system are connected via connectors 15 to the air supply tubes 14 and are connected to air pumps 23 via a two-position acting solenoid valve 20 and an air supply/discharge controller C for actuating this valve.

Title: Device and method for magnetic recording and reproducing
Inventor: MIZUMAKI HIDETAKA
IPC: G11B5/02
Filed: 1990-05-31
Abstract: PURPOSE:To completely restore an input signal by adding a pulse to emphasize a rise pulse and a fall pulse at the time of converting a digital signal, which is obtained by frequency modulation of an analog input signal or is directly inputted, to a pulse train signal. CONSTITUTION:An output signal O of a reproducing amplifier 13 has sharp rise and fall. This output signal O is compared with a converter level 01 by a comparing circuit 14, and the high level is outputted when the level of the signal O is higher than the level 01, and the low level is outputted when the level of the signal O is lower than the level 01. Consequently, a digital signal P is obtained in the output of the comparing circuit 14. The crossing point to the level 01 is exactly detected in this comparing operation because the rise and fall of the signal O are sharper than those of a conventional output. Thus, an original digital signal C is completely restored.

Title: Photomagnetic reproducing device
Inventor: HATSUTORI YUTAKA
IPC: G11B11/105
Filed: 1983-08-06
Abstract: PURPOSE:To obtain an inexpensive reproducing device of simple structure which causes no loss of the quantity of light by using a polarization beam splitter and a quarter-wavelength element, converting linear polarized light into circular polarized light and irradiating a photomagnetic material of vertical magnetism with the light, and reconverting the reflected light into linear polarized light and detecting the quantity of the reflected light. CONSTITUTION:The light polarized light incident from a light source to the polarization beam splitter 14 is transmitted efficiently, and reflected by the polarization beam splitter 14 by about 100% because the reflected light from the photomagnetic material 18 is made perpendicular to the linear polarized light from the light source by the quarter-wavelength plate element 16. Therefore, the loss of the quantity of light caused when the linear polarized light from the light source is transmitted through the polarization beam splitter 14 and when the reflected light is reflected is improved. Further, the need for an analyzer, differential detector, etc., for detecting the rotation of the oscillation plane of the linear polarized light of the reflected or transmitted light from the photomagnetic material is eliminated, and the device is constituted easily at a low cost.

IPC: H04W88/02
Filed: 1992-06-04
Abstract: PURPOSE:To attain talking between slave sets through the use of one speech channel set by selecting an idle speech channel with a slave set and using the selected speech channel to select alternately the transmission and the reception. CONSTITUTION:An inter-slave set line setting section 8 of a slave set 1 receives a connection request to a slave set 2 from a key entry section 3 upon the occurrence of a connection request to the slave set 2. The inter-slave set line setting section 8 of the slave set 1 gives a command to a transmission reception frequency changeover section 4 to allow the section 4 to select the transmission frequency to be a reception frequency of the slave set 2. Moreover, the line setting section 8 selects an idle speech channel. When an idle speech channel is selected, the slave set 2 sends a connection request signal. Then the section 8 gives a command to the transmission reception frequency changeover section 4 that the frequency of its own transmitter-receiver is switched to the frequency of the selected channel number. On the other hand, the slave set 2 gives a command to the transmission reception frequency changeover section 4 to allow the section 4 to select a frequency relevant to the channel number sent from the slave set 1. A transmission radio wave transmission section 6 and a reception signal interrupt section 7 of the slave set 2 are operated.
