IPC: H04W84/02
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To make a reception state stable by suppressing the deviation in a local oscillating frequency. SOLUTION: The receiver uses a mixer 41 to mix a local oscillating frequency from a local oscillation circuit 2 and a frequency of a received high frequency signal, a detection circuit 45 detects the received signal based on the IF signal, a comparator 8 digitizes the detection signal according to a prescribed reference signal and a decoder 9 obtains a demodulated signal based on the digital signal. In this case, a reference voltage generating circuit 6 conducts charging/discharging according to a QC (quick charge) signal from the decoder 9, a reverse voltage is applied to a variable capacitance diode 3 connected between the local oscillation circuit 2 and the mixer 41 with the reference voltage in response to a mean voltage of the detection signal at discharging to change the capacitance thereby applying feedback compensation to the deviation in the local oscillation frequency.

Abstract: PROBLEM TO BE SOLVED: To make a person requiring nursing care bathe by himself by forming seat sections having a height, which is approx. the same as the height of the upper edge of a bathtub, on both sides of the bathtub, and forming handrails on the seat sections. SOLUTION: When getting into a bathtub 1, a person requiring nursing care sits on a seat section 2a for a time, and places both legs in the bathtub 1 by rotating his body while bonding onto handrails 5a and 5b. Then, by moving the center of gravity to the leg side, the person can enter the bathtub 1. When he gets outs from the bathtub 1, he sits on the seat section 2a for a time while holding the handrails 5a and 5b with legs being kept in the bathtub 1. Then, by rotating his body while holding onto the handrails 5a and 5b, both legs are taken out from the bathtub 1, and he can get out from the bathtub 1. Since the seat sections 2a and 2b are formed on both sides of the bathtub 1, the person requiring nursing care can get in or get out from the bathtub 1 by using the seat section on the side which is easier to use.  Also, at the time of body washing, he can easily wash his body by washing his body under a sitting state on the seat section.

IPC: G06F1/26
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent a player from being at a disadvantage with little power consumption by continuously maintaining absolute minimum storage ability capable of returning a state before power failure restoration at the time of the power failure restoration while a power failure occurs and a normal power supply voltage is not supplied to electronic control equipment (during the power failure). SOLUTION: For a power failure processing, a processing for becoming the state immediately before the power failure after the power failure restoration is executed. At the time, since information required to be surely stored is present, the information is stored in backup areas 42A and 142A in the RAM 42 of an IC 38 and the RAM 142 of the IC 138. Since the backup areas 42A and 142A maintain an active state by the power supply voltage (about 4.5 V) supplied from an electric double layer capacitor during the power failure, the information is held after the power failure restoration.
