Title: Congestion follow-up system and vehicle controller
Inventor: SAKUKAWA JIYUN
IPC: B60W20/00
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To facilitate the operation of a driver, and to simplify a structure in a constitution where follow-up treatment is executed under the condition of the switching operation of the driver. SOLUTION: A follow-up controller 10 controls an electronic throttle 16 and a brake 18 based on the detecting signal of a car-to-car distance sensor 14, and performs follow-up treatment to cause an own vehicle to follow up a preceding vehicle. This follow-up treatment is carried out under the condition of depressing operation of an accelerator pedal 22. Because of accelerator depressing, an operation for instructing follow-up execution is facilitated. In a congestion follow-up mode, since the accelerator pedal 22 is effectively used, which is unnecessary originally, a structure is simplified. Further, driving is further facilitated by switching between a semiautomatic follow-up mode needing an accelerator operation and a full-automatic mode not needing the accelerator operation according the current position of the vehicle.

Inventor: FURUKOUJI MINORU
IPC: E03D9/08
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a sanitary cleaning device which can obtain comfortable cleaning feeling in both buttock cleaning mode and a bidet cleaning mode. SOLUTION: A sanitary cleaning device is composed so that the temperature and strongth of a jetted cleaning water may be controlled according to a setting by a user. A remote controller is provided with an operation section which can severally independently set the temperature and strength of the cleaning water in buttock cleaning mode and a bidet cleaning mode. The cleaning device is composed so that even in the case where one cleaning mode is acting, the water temperature and water strength in the other cleaning mode can be set. In addition, a setting range in the bidet cleaning mode is set narrower than that in the buttock cleaning mode.  Therefore in buttock cleaning mode, the temperature and water strength are adjustable in a wide range so as to obtain desirable cleaning feeling, and in bide cleaning mode, the jetting of the cleaning water in an exciting state is restrained, and thus the comfortable cleaning can be realized in both cleaning modes.

Title: Comparator
Inventor: UENO MASAYUKI
IPC: H03K5/08
Filed: 1991-11-12
Abstract: PURPOSE:To reduce the size of a comparator by positively feeding back the output of a differential amplifier circuit as control voltages for the current sources of first and second source follower circuits. CONSTITUTION:Positive feedback circuits are respectively formed by connecting output terminals 3A and 3B on the drain sides of MOS transistors 3a and 3b, to which the first and second source follower circuits 1 and 2 of a differential amplifier circuit 3 supply electric power, to the gates of the current sources 1c and 2c of the circuits l and 2. When the output of the circuit 3 is positively fed back to the current sources 1c and 2c of the circuits 1 and 2 as control voltages, the current values of the sources 1c and 2c decrease (increase) when, for example, voltage A > voltage B and the outputs of the circuits 1 and 2 are finally stabilized at high (low) voltage levels. When voltage A < voltage B, the outputs of the circuits 1 and 2 are stabilized at low (high) levels by a reverse action. Since the magnitudes of the voltages A and B can be discriminated based on the output of the circuit 3 which inputs the outputs of the circuits 1 and 2, this comparator normally operates even when the output of the circuit 3 is positively fed back and the number of elements can be reduced. Therefore, this comparator can be reduced in size.

Abstract: PURPOSE:To securely perform defrosting by detecting the defrosting not being performed even at defrosting start time by a defrosting detecting means, and powering ON a defrosting heater and performing the defrosting once a temperature detecting means detects ambient temperature being lower than predetermined set temperature. CONSTITUTION:When a defrosting heater detecting circuit 6 detects the defrosting heater 5 not being powered ON even at the defrosting start time, it is decided through the clocking of a timer 3 after the defrosting start time whether a previously set time is elapsed and when the certain time is elapsed, the temperature sensor 4 judges whether or not the temperature in the box is lower than the set temperature, so that forcible defrosting is not performed unless the in-box temperature is lower than the set temperature. When the set temperature is higher than the in-box temperature, a forcible defrosting start relay 72 is energized to make its contact and the defrosting heater 5 is powered ON to start the defrosting. Then it is decided whether or not the in-box temperature is lower than the set temperature, and when not, the defrosting heater is powered OFF to end the defrosting.
