Title: Device for recovering exhaust heat of engine
Inventor: MATSUI HIROTOMO
IPC: F02G5/00
Filed: 1988-10-12
Abstract: PURPOSE:To prevent the hunting phenomenon of a thermo-valve by opening a closing valve provided on a bypass flow passage of an exhaust heat recovering device only when the temperature of a heat absorbing liquid is lower than a set value. CONSTITUTION:As a low-temperature heat absorbing liquid is fed to an exhaust heat recovering device 4 in an exhaust heat recovering operation mode, a bypass flow passage closing valve SV3 is opened to make part of engine cooling water flow short-circuitedly to an outlet side flow passage without passing through the exhaust heat recovering device 4. Thereby, the quantity of the engine cooling water fed to the exhaust heat recovering device 4 is restricted to restrain the temperature of the engine cooling water returned to a water jacket 1 from being extremely lowered. Hence, a thermo-valve TV is not switched over to the opening condition of the bypass flow passage (j), restricting heat radiation from the engine cooling water. After that, as the temperature of the heat absorbing liquid is increased, the bypass flow passage closing valve SV3 is closed to feed the whole quantity of engine cooling water to the exhaust heat recovering device 4. Thereby, the hunting phenomenon of the thermo-valve can be prevented.

Title: Disk controller
Inventor: IZEKI TOSHIYUKI
IPC: G11B19/02
Filed: 1986-10-31
Abstract: PURPOSE:To control disk devices of several types of formats by providing a means which stores the information on the processing length and the information on the processing contents, i.e., the disk control information given from a host computer and a means which reads each information received from said storing means and at the same time performs the prescribed processing. CONSTITUTION:A control information storing means 12 stores the information on the processing contents and the information on the processing length and outputs the control information on the address shown by an address changing means 4. A counting means 3 reads the information on the processing length and gives an instruction to the means 4 when the count value is equal to '0'. Thus the means 4 changes addresses and shows the changed addresses to the control information storing means 1 and 2. These means 1 and 2 store the addresses with an instruction of a control part 7 for display of them. Thus the information on the processing contents are successively read by an amount equal to the processing length and can also be read out of an optional address.

Filed: 1989-10-02
Abstract: PURPOSE: To judge the presence of the defect of an insulator by providing a long ionization electrode and an electric field electrode, performing the discharging with a cable to be tested, and detecting the real current of a conductor. CONSTITUTION: A long ionization electrode 2 and a long electric field electrode 3 are retained in such a relationship that they are isolated each other by a plurality of insulation spacers 4.

IPC: H01K1/46
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide an electric bulb having a long lifetime excels in the vibration proof property, and presents a long on/off lifetime. SOLUTION: A plurality of small-sized electric bulbs 1 having no socket base are connected in series and accommodated in an envelope 2 upon assembling, and a base 3 is mounted on one end of the envelope 2. The envelope 2 is made of a synthetic resin and composed of a basis 2a and cap 2b, and thereby a large strength is assured and an equivalent shape to that of a commercially available electric bulb can be embodied, for example nutmeg bulb form, small round bulb form, tapered light bulb form for shrine, chandelier bulb form, etc. The basis 2a is equipped with a holder part 2a2 to hold a seal part of the obtained baseless small-sized electric bulb. If at least the cap part 2b is made of a colored synthetic resin with transparency, a color electric bulb having much colored light is obtained as there is no colored coating film.  Because a baseless small-sized electric bulb 1 with a low voltage may be adopted according to the described configuration, the filament 1b is short and has long life, and there is less stress resulting from on/off to lead to a long on/off lifetime, and also an excellent vibrational proof property is assured owing to holding of the bulb 1 in the basis 2a.

Title: Suction pipe for cleaner
Inventor: NEMOTO SUSUMU
IPC: A47L9/02
Filed: 1988-10-14
Abstract: PURPOSE:To eliminate the replacement of a convergent nozzle suction port component, and thereby contrive to make cleaning operations smooth by constituting the elastic cylindrical body of the end section of a pipe main body to collapse when it is made free, and also to become cylindrical again roughly equal to a suction passage in diameter when it is restrained. CONSTITUTION:When the corner section of a room is cleaned, A form restraining section 13 is slid so as to be fastened at a slide limit position 11b on the left side so that it is apart from the outer circumferential section of an elastic cylindrical body 12. This permits the original tip end of the cylindrical body 12 to be collapsed in shape while being narrowed so as to make an opening section a convergent nozzle suction port. Accordingly the cylindrical body 12 performs the same function as that of a convergent nozzle suction port component 4 in this case. In addition, the projections 12a of the cylindrical body 12 prevents the suction port from being completely collapsed so as to be blocked by abutting onto one another. In the second place, when a carpet and the like are cleaned, the form restraining section 13 is slid so as to be fastened at a slide limit position 11c at the right side so that it is forcibly coupled with the elastic cylindrical body 12. This permits the cylindrical body 12 to be restrained in such a way as to be formed into a cylinder with a circular cross section. After then, the base end section 4b of a suction port component in a box shape is inserted into the tip end of the cylindrical body 12 which has been formed into a box shape in cross section so that connection is thereby made.
