Title: Magnetic head
Inventor: UCHIBORI NAOKI
IPC: G11B5/105
Filed: 1985-05-07
Abstract: PURPOSE:To decrease the total height of a head, and that of a core itself and to improve the efficiency of a magnetic circuit, by forming a recess part to a slider to produce a space where a back bar is stored. CONSTITUTION:Slider half sections 1a and 1b are provided together with a back bar 2, a coil 3, a core 5 and a spring 6. The section 1a contains a recess part 1a' which forms a space to store the bar 2 and the coil 3. The bar 2 is held between the core 5 and the section 1a and energized toward the core 5. Thus the bar 2 is not projected over the bottom surfaces of both sections 1a and 1b and can be positioned at the inner side. Therefore, the total height of the core 5 can be made less than the height of a slider unlike a conventional structure.

Title: Fixing device
Inventor: INAGAKI SANJI
IPC: G03G15/20
Filed: 1987-04-20
Abstract: PURPOSE:To enable a pressure roller itself to clean a heat roller by providing a means which varies the relative rotating speed between the heat roller and pressure roller and setting different relative rotating speeds in the paper feeding state and nonfeeding state of copying paper. CONSTITUTION:When a fixing process is finished and the heat fixing roller 30 and pressure roller 40 are pressed directly against each other, the control part 502 for a driving circuit 501 sends an output command so that a 1st driving motor M1 and a 2nd driving motor M2 rotate at different speeds. The heat roller 30 and pressure roller 40, therefore, rotate at mutually different peripheral speeds V1 and V20 and the peripheral speed (relative speed) of the brush 410 of the pressure roller 40 is different from that of the heat roller 30, so friction is caused on the surface 300 of the heat roller 30. Consequently, if toner sticks or remains on the surface 300 of the heat roller 30, the residual toner is scraped off the surface 300 of the heat roller 30 or swept away to clean the surface 300 of the heat roller 30.

A beryllium copper plate is used for the contact 1, which is so formed by means of stamping that a plate thickness (t) and a spring width (w) of the spring part 2 become 0.1 mm and 0.9 mm, respectively. A contact 3a located at the tip of the contact part 3 of the contact 1 is subjected to making preliminary face so as to be spherical in shape in the fractured surface, and so as to form it into a point contact having R=0.1 mm. Thereafter, the entire contact 1 is plated with Ni and thereby, a coating having a thickness of 2.54 μm is formed on it, and the spring part 2 is allowed to have high elasticity. Thus, good contact can be provided at low cost.

IPC: G03G15/06
Filed: 1989-04-19
Abstract: PURPOSE:To stably form an image of sufficient density by adhering developer on a developer carrier in a non image area between a first image area of an electrostatic latent image and a following second image area during image formation. CONSTITUTION:To form a part which has lost its electrical charge in a non image area on a photosensitive drum 1 between the pages of an image forming cycle by a controlling means. By developing the electrostatic latent image of the non image area, a specified quantity of non magnetic toner 10 on a developing sleeve 5 is traveled at a fixed timing to the drum 1, and almost none of the toner 10 is made to residue on the sleeve 5. Therefore, since the toner 10 on the sleeve 5 is traveled to the drum 1 and appropriately fed by a developer replenishing device 4a, providing excessive friction electrification to the toner 10 can be prevented. Thus, a developer layer with appropriate electrical charge can be formed on the developer carrier.

Title: Gas meter
Inventor: NUKUI KAZUMITSU
IPC: F23N5/18
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To measure the gas consumption amounts of various kinds of apparatus with different charges by one gas meter by providing a control unit which functions in such a manner that the driving of a second gas apparatus is recognized, and based on an increased gas amount at that time, the flow rate is integrated by a second gas flow rate counter, and a first gas flow rate is integrated by a gas flow rate from which the portion for the second gas apparatus is subtracted. SOLUTION: When a flow rate increases, whether the amount stays within an individual maximum amount or not is checked (S6), and at the same time, the variation of a high frequency of a pressure/flow velocity sensor output is checked (S8). In the case of a change, an integration is started (S9) by a gas engine heat pump(GHP) counter, based on the increase amount, and in the case of no change, it is recognized and registered as the driving start of a general gas apparatus, and the measuring of time is started (S10). When the total flow rate decreases, and the high frequency variation stops, the integration of the GHP counter is stopped (S13), and when the variation continues, the register of the general apparatus driving which corresponds with the decrease amount, is deleted.  As a result, the integration can be performed based on the increase amount at the time of a high frequency variation for the GHP counter, and based on the amount for which the consumption amount for cup is subtracted, for a counter for general apparatus.

Title: Device for controlling air-fuel ratio of engine
Inventor: FUJIMURA SHUNSUKE
IPC: F02D41/14
Filed: 1988-04-21
Abstract: PURPOSE:To obtain both controlling stability at the time of no-traveling and responsiveness at the time of traveling by varying the control gain of an air-fuel ratio feedback control in line with a traveling condition. CONSTITUTION:When there are changes of an idling switch 19 and a gear-IN movement, the control gain of air-fuel ratio feedback control is varied in line with a traveling condition in a controller 15. That is, at the time of idling, the control gain is made lower reducing variation in air-fuel ratio to obtain a controlling stability and suppress vibration. When a traveling condition is detected even in the idling condition, since the variation in air-fuel ratio is hard to be bodily sensed, correction is made to increase the control gain, thereby, improving a controlling responsiveness while reducing deviation from a target value to obtain a good fuel consumption performance and good emission performance.
