Title: Magnetic tape driving device
Inventor: OURA HIDEKI
IPC: G11B15/28
Filed: 1987-12-29
Abstract: PURPOSE:To keep a magnetic tape in its prescribed traveling position and to reduce accuracy and labor for assembly and adjustment by detecting positions of an upper edge and a lower edge of the magnetic tape under traveling and controlling the oblique angle of a capstan shaft. CONSTITUTION:When the lower edge of the magnetic tape 1 is shifted upward from the prescribed position during the travel of the tape 1 in the direction of (a), the lower edge of the tape 1 is separated from a sensor lever 15, and the force of the tape 1 to push down the lever 15 is decreased. Consequently, the lever 15 under elastic deformation due to the tape 1 is bent upward due to its elastic force, and this bending amt. is outputted as a voltage by a strain gauge 16. This voltage is amplified and impressed on double-sided electrodes of a piezoelectric element 26, so as to shrink the piezoelectric element 26, thus moving a sliding plate 24 in the direction of (c) by a few microns. The inclination of the capstan shaft 12 is changed by interlocking with the sliding plate 24, so that the magnetic tape 1 can be kept in the prescribed traveling position, thus reducing the accuracy and labor for the assembly and adjustment.

Abstract: PURPOSE:To use a power voltage effectively and to reduce the current change due to temperature by connecting an emitter resistor to an oscillation transistor(TR) only and using the TR to a final stage of a bias circuit. CONSTITUTION:An output of the oscillation TR 12 is fed from the emitter to a base of a TR 9 via a coupling capacitor C14 and its output is fed to a base of a TR 3 from the collector of the TR 9 via a capacitor C7.

Abstract: PURPOSE:To enable both the easy carrying out of heating operation and the preservation of a food in a state thereof housed in a package after heating. CONSTITUTION:A food 17 is housed in a food housing space 13 formed in an electrical conductive bag body (10a) and the food housing space 13 is hermetically sealed. In this state of the space, Joule's heat is then generated in the food 17 using electrode members 14 and 15 installed in the electrical conductive bag body (10a). Thereby, the food 17 is heated. The parts of the electrode members 14 and 15 are then separated from the electrical conductive bag body (10a) to form a package 10 in a state of the food 7 filled in the interior thereof. Thereby, the electrode members 14 and 15 of the electrical conductive bag body (10a) are utilized to carry out the heating of the food 17 and the electrode members 14 and 15 are removed after the heating. As a result, the contact of the electrode members 14 and 15 with the food 17 is avoided in a process for storing the food and metallic members can be used as the electrode members 14 and 15 to carry out the heating and preserving of the food 17 at a low cost.

Title: Shifting device
Inventor: KATO MASAYUKI
IPC: F16H61/16
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To prevent a change gear ratio of a transmission from being changed unexpectedly when starting a vehicle. SOLUTION: This shifting device capable of selecting an operating position of a shift lever among a non-driving position, a driving position and a transmission control content changing position, is equipped with an intention determining means (step S1 to S4) and a control change inhibit means (step S5). The intention determining means determines whether the operation of changing the shift level from the driving position to the transmission control content change position is based on an occupant's intention or not when the shift level is selected to operate from the non-driving position through the driving position to the transmission control content change position.  The control change inhibiting means inhibits the change of the speed change step of the transmission from from the first speed to the second speed when determining that the operation of changing the driving position to the transmission control content changing position is not based on the occupant's intention.

Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To allow a host side in a wireless system to automatically delete an ID number or to make an emergency setting in the case that the operation of a terminal used for the wireless system is stopped. SOLUTION: In the case of stopping an operation of a wireless sensor, a power switch 30 is depressed for a time and then detached. In this case, a power supply voltage is applied to a signal input port P1. When a voltage of a prescribed threshold voltage or over is applied to the signal input port P1, a control section 7 that is in operation through the reception of power, discriminates that power-off operation is made, generates data denoting the power-off and transmits the data to open a switch 33. The host side receives information denoting the power-off to recognize that the operation of the wireless sensor is stopped in such a way that the host side can automatically delete the ID number of the wireless sensor or can make an emergency setting to the wireless sensor of the ID number.

The formation of the excess through pores is suppressed by intentionally forming the through pores. The high yield over the entire part of the sintered layer and the high sintering speed are obtd.

Title: Conductive roll
Inventor: UTSUNOMIYA TADASHI
IPC: G03G15/02
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a roll which has high adhesion property to a photoreceptor and suppresses contamination on a photoreceptor and in which change in the electric resistance are suppressed and cracks or wear are prevented for a long time by forming an intermediate layer comprising a material which contains a solid rubber and a liquid rubber to be mixed as a softening agent in the solid rubber. SOLUTION: The intermediate layer 2 is formed, for example, by using a solid polybutadiene rubber into which a liquid polyisoprene rubber is compound by 10 to 50 PHR rubber in order to improve the adhesion property to a drum type phtoreceptor. The liquid rubber used is preferably such a rubber having double bonds in the main chain and >=10000 number average mol.wt. By using the rubber having this mol.wt. range, most of the rubber molecules react with the solid rubber during vulcanization and do not dissolve in a coating material. Even the molecules remaining as unreacted hardly dissolve in the coating material because of the high mol.wt. When the intermediate layer 2 above described is formed and then a coating material is applied to form a coating layer 3 thereon, the softening agent does not diffuse into the surface of the coating film.
