Title: Toner cartridge
Inventor: YOSHIKI SHIGERU
IPC: B65D83/06
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent toner leakage before and after use and to improve operability by closing a discharge port for discharging toner from a toner cartridge by two steps, that is, a shutter device and a seal member. SOLUTION: A path from an aperture part constituting a path for discharging the toner from the toner cartridge to a toner supply port through a slit hole 219a and the toner discharge port is sealed by two steps, that is, the shutter device 203 and a gate seal 210. The shutter device 203 prevents the toner leakage at the time of operating the toner cartridge, and sealing performance against the toner leakage at the time of transportation is secured by the seal 210. The seal 210 is superposed on the gate and covers over the slit hole 219a so as to prevent the toner leakage from the slit hole 219a of the gate of the toner cartridge in an unuse state. The end side of the seal 210 which has been folded back is exposed to the outside through a seal pulling slit 201a, so that peeling operation is facilitated.

Title: Electric heater to prevent freezing of rail point
Inventor: MATSUZAKI SHIGEMI
IPC: E01B7/24
Filed: 1994-04-18
Abstract: PURPOSE:To equalize the temperature by making the interval between ferromagnetic pipes small as far as possible, and besides, welding them with each other at specified pitch in the longitudinal direction of the ferromagnetic pipe, and heating them from both directions of a rail receiving plate by a conductive current heating tube. CONSTITUTION:Conductive ferromagnetic steel pipes (heating tubes) 3 and 4 constitute a main secondary circuit to a power source 1 and a cable 2 being a primary circuit, and the main secondary current i2 flows, passing along the inner surfaces of the heating tubes 3 and 4 and through the connections 5 and 6. Furthermore, a plurality of connections (welding) 9 and 9' are provided at pitches of 5-10cm as the additional connections of the heating tubes 3 and 4. Thereupon, in each connection, an additional secondary current in the same direction as the secondary current i2 being in the direction where it negates the magnetic flux made by the primary current i1 is generated, and in the connection 9, currents i20-i2n, etc., and in the connection 9', currents i20-i2n', etc., which lessens leaked outside magnetic fields. The leaked electromagnetic fields to outside of the heating tubes 3 and 4 decrease by 10-30%, and the hindrance to a signal circuit vanishes. If a heater tube 34 is provided outside the rail receiving plate, the generated heat is transmitted directly to the rail receiving plate.

Title: Image pickup device and attachment lens
Inventor: SAITO TOMOHIRO
IPC: G02B15/12
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To effectively avoid a problem of causing an eclipse, and to variously change a focal distance by a small number of attachment lenses by arranging first/second attachment lenses selectively arrangeable in a main body lens, and setting the main body side first attachment lens at this time to power higher than the second attachment lens. SOLUTION: A digital camera 1 can change a focal distance by a main body lens 2 by selectively installing an attachment lens 4 or 5 by a mount 3 when necessary. Here, while the attachment lens 4 is, for example, 1.6 times in power, the attachment lens 5 is set to 1.25 times in power. Thus, while a focal distance of an optical system can be changed to 1.6 times and 1.25 times by respectively installing the attachment lenses 4 and 5, the focal distance can be changed to about two times by installing the attachment lens 5 in front of the attachment lens 4.

Abstract: PROBLEM TO BE SOLVED: To obtain an ink jet recorder in which temperature rise of a piezoelectric element as an ink droplet jetting head is restrained by using a nozzle plate in order to suppress variation in the viscosity of ink, to stabilize the jetting characteristics of ink droplet and to enhance the image quality. SOLUTION: In order to suppress self heating of a head drive element, i.e., a piezoelectric element, fixed to a head nozzle plate 201 constituting the head unit of an ink jet recorder, surface area of the head nozzle plate 201 is increased by providing protrusions and recesses 301 thereon and the protrusions and recesses 301 are directed in the main scanning scanning direction 302 of the head unit so that the air flow produced through main scanning operation, i.e., reciprocal operation, of the head unit is passed smoothly between the protrusions and recesses. Consequently, the head plate is cooled down and temperature rise of the piezoelectric element is suppressed. Furthermore, a planar part is provided between the protrusions and recessed in order to prevent a print sheet from being caught thereby.

Abstract: PROBLEM TO BE SOLVED: To appropriately execute the finishing judgment of a shift at the time of a shift that one frictional element is released and also the other frictional element is fastened, by providing shift finishing judgement means for judging the finishing of the shift on the basis of the detection of the fastening condition detecting means of the frictional element. SOLUTION: In the case of a 4-3 shift, a duty solenoid valve is controlled, mainly as shift, by a third DSV 123 for fastening a forward clutch, and the duty rate of the third DSV 123 is judged whether or not is becomes approximately 0%. When the duty rate is in such a shift finishing condition, it is judged that the shift is finished, and a shift flag is set to 0. That is, the finishing of the shift is not judged from a condition when a turbine rotational speed increased by the releasing action of a releasing side frictional element becomes in a shift finishing period, but judged when the fastening action of a fastening side frictional element is actually completed.

Title: Engine idle rotational speed control method
Inventor: KOBAYASHI KOUICHI
IPC: F02D41/16
Filed: 1984-05-22
Abstract: PURPOSE:To prevent the occurrence of blow-up, engine stall and delay in control, by carrying out the closed-loop control of idle rotational speed of an engine after the idle opening degree of a throttle valve is set to a specified value. CONSTITUTION:When an accelerating pedal is moved back upon running of a vehicle, the desired throttle opening degree is set to a load opening degree at the step 105. If the throttle opening degree is in a dead zone at the step 108, the idle rotational speed control is carried out at the step 109. If it is out of the dead zone, the idle rotational speed control is carried out such that the desired throttle opening degree is made equal to an actual throttle opening degree. Thus, even if a delay time is uniformly set, no problems of blow-up, engine stall, delay in control, etc. occure so that man-hours for setting a delay time may be greatly reduced.
