Title: Method for managing storage of optical disk
Inventor: HASEGAWA YUKICHI
IPC: G06F12/00
Filed: 1987-10-27
Abstract: PURPOSE:To surely recover directory information stored in an other memory device when it is destroyed by storing information on an optical disk in a state where separate information is attached on a data file. CONSTITUTION:A recording track formed on the optical disk 5 is divided into sectors with prescribed length, and the data file DF consisting of image data or retrieval information is recorded in the continuous area of a data area at every sector unit in the state where a file separation header FSH to represent the separation of the data file DF is attached at its leading position. Thereby in case of reading no directory information due to the destruction of a storage content in a magnetic device 6, a system control part 1 executes a prescribed processing, and recovers the directory information by referring to the data area of the optical disk 5, which improves the reliability of the optical disk.

IPC: B60W10/11
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To perform proper control when an abnormality has occurred in an automatic clutch device. SOLUTION: Failure in an automatic clutch device is sensed by an engine ECU or automatic clutch ECU (S100, S102, S104, S106). According to the sort of an abnormality sensed, the specified fail-safe control is performed (S110, S114, S120). If in particular, the failure occurs to the automatic clutch ECU (S100), a clutch solenoid valve (S102), or a power supply system of the automatic clutch ECU (104), either the engine output is sunk or the engine is stopped (S110 and S114). This reduces shock at the time of engine stall, etc.

In addition, as parts of the expanded artificial muscles 20 and 21 are expanded out from the gap of the controlling ring 31, the amt. of expansion required for curving a curved part 2 can be ensured. There exists thereby no damage of the built-in members and it is possible to make the inserting part thin and lightweight.

Abstract: PROBLEM TO BE SOLVED: To prevent outdoor air of low temperature from flowing into a control box by a method wherein there is provided a sensor for sensing an outdoor temperature, a cooling fan is constituted of a fan which can be rotated in a normal direction and in opposite direction and then the fan is switched over to its normal rotation or its reverse rotation in response to the temperature of surrounding air detected by the sensor. SOLUTION: A cooling fan 40 which can be rotated in a normal direction or a reverse direction is arranged at an air discharging port 15 formed at an upper part of a control box 13. The cooling fan 40 is controlled by a fan control means 41. A detected temperature of a sensor 42 for use in detecting a temperature of the surrounding air is inputted to this fan control means 41, the inputted temperature is compared with data stored in the fan control means 41.  If the outdoor temperature is higher than a set temperature, it is determined that the rotation is a normal rotation, and in turn if the detected temperature is lower than the set temperature, it is determined that the rotation is a reverse rotation and concurrently, the number of rotation of the normal direction and the number of rotation of the reverse rotation are determined in response to a deviation between the detected temperature and the set temperature. With such an arrangement as above, it is possible to prevent outdoor air of low temperature from feeding into the control box 13, resulting in preventing electronic component parts stored in the control box 13 from showing maloperation or failing to work properly.

Title: Bath water supplying apparatus
Inventor: FUKUDA HIROSHI
IPC: F24H1/46
Filed: 1990-10-09
Abstract: PURPOSE:To prevent uselessly disposing of hot water from a hopper even when a large amount of hot water is used at other places during automatic water supplying operation by a method wherein the automatic water supply is interrupted temporarily when an automatic water supplying flow rate drops down below a set value, and when an interruption reason is removed, the automatic water supply is continued successively. CONSTITUTION:When a hot water supply valve is opened, hot water heated by a hot water supply heat exchanger 1 is supplied through a hopper 8 and a circulation passage into a bath tub 5, and when water in the bath tub 5 reaches a proper temperature and a proper volume, the hot water supply valve 6 is closed to end an automatic water supply operation. In this instance, if a hot water supply tap 4 is opened during the automatic water supply and used water volume on the water supply tap 4 side is so large that water volume flowing to the hopper 8 side drops down below a prescribed value, a flow rate switch 12 detects an OFF flow rate, and a valve 7 is opened while the hot water supply valve 6 is closed so that the automatic hot water supply is made to stand by. After that, when the use of water through the hot water tap 4 is finished and the tap 4 is closed, a flow rate sensor 2 detects OFF to open again the hot water supply valve 6 to restart the automatic water supply. If the water supplied into the bath tub 5 reaches a proper temperature and a proper volume, a hot water supplying operation is stopped.
