Title: Air-fuel ratio control device for internal combustion engine
Inventor: FUKUYAMA YOSHIAKI
IPC: F02D41/14
Filed: 1993-01-30
Abstract: PURPOSE:To prevent a change in an air-fuel ratio, reduce a harmful component in exhaust air, and improve operability by switching a learning correction factor map to carry out feedback control on an air-fuel ratio when an operating condition changes between a condition where evaporation fuel of a canister is released to an internal combustion engine and an unreleased condition. CONSTITUTION:A control part 44 carries out opening and closing control on a purge valve 42 according to various detecting signals of various kinds of sensors 46, 48, 50, 52 and 54 to detect an operating condition of an internal combustion engine 2, and releases evaporation fuel adsorbed to/held with a canister 34 to an intake air passage 4. The control part 44 carries out driving control on a fuel injection valve 24 according to a detecting signal of an O2 sensor 46, and carries out feedback control on an air-fuel ratio. Learning correction is carried out on the feedback control by a factor of a map. In this case, when the evaporation fuel is released, a map is switched to a releasing map after release delay time being set by the operating condition passes. On the other hand, when the evaporation fuel is not released, it is switched to a non-release map after non-release delay time being set by the operating condition passes.

Title: Peak type magnetic head
Inventor: KAWAMURA NAOKO
IPC: G11B5/187
Filed: 1982-03-05
Abstract: PURPOSE:To obtain excellent output characteristics in a short-wavelength range, by bringing the contacting length of a core half bodies at the run-out side of a magnetic recording medium to nearly <=3 times as great as the maximum recording wavelength of a recorded signal. CONSTITUTION:A magnetic head 1 is made into a peak type head by shortening the lengths l1 and l2 of magnetic recording medium sliding surfaces 4a and 4b of the front end surfaces of core half bodies 1a and 1b as much as possible, thereby increasing the pressure of contacting with the magnetic recording medium. In concrete, the contacting lengths l1 and l2 are set at <=3 times as great as the maximum value of recording wavelength lambda, i.e. 40-50mum. Consequently, the pressure which is in contact with a tape is increased and excellent output characteristics in a short-wavelength range are obtained even when the running tension of the recording medium is decreased.

Title: Image forming device
Inventor: KUMON TOSHIHIKO
IPC: G03G21/00
Filed: 1989-02-13
Abstract: PURPOSE:To eliminate the unnecessary adhesion of toner to a photosensitive body accompanied with impressing developing bias by forming a bristle cutting state before the developing bias is impressed on a developing device and before the leading edge of the electrostatic charging part of the photosensitive body reaches a position where the developing device is disposed and maintaining the state until it passes the disposed position of the developing device. CONSTITUTION:An image is formed in electrophotographic copying process in which the developing devices 5 and 6 disposed around the photosensitive body 1 are used. A bristle cutting means 80 performs bristle cutting processing for preventing the developer from adhering to the photosensitive body 1 to the developing devices 5 and 6. A control means 12 controls the action of the bristle cutting means 80 so that the bristle cutting state is formed before the developing bias voltage is impressed on the developing devices 5 and 6 and before the leading edge of the electrostatic charging part of the photosensitive body 1 reaches the position where the developing devices 5 and 6 are disposed and also the bristle cutting state is maintained until the leading edge of the electrostatic charging part of the photosensitive body 1 passes the position where the developing devices 5 and 6 are disposed. Thus, the unnecessary adhesion of the toner in the developer to the photosensitive body 1 accompanied with impressing the developing bias is eliminated and the wasteful consumption of the toner is reduced.

Abstract: PURPOSE:To aim at securing a black matrix excellent in uniformity in an easy manner, by interposing a humidifying process moisturizing the internal surface of a panel at the specified speed between exposure and developing processes. CONSTITUTION:After a register film is exposed to light, the surface of the register film is moisturized at a humidifying speed of 0.1-8cc/min for 15-20sec prior to the developing process under the conditions that room temperature is 23 deg.C, indoor relative humidity is 60-65%, register film surface temperature is 30-35 deg.C and developer temperature is 40 deg.C by way of example.
