Title: Developing apparatus
Inventor: SHIMIZU TAMOTSU
IPC: G03G21/14
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a developing apparatus which can obtain a half-tone image having both an appropriate image density and a fine texture when development is performed by applying an alternating current electric field on a developing region where a developer carrying body and an image bearing body face to each other. SOLUTION: A developing apparatus makes a developer carrying body 11 hold developer 2 on its surface and convey the developer 2 to a developing region facing to an image bearing body 1, and also performs development by putting an operation period (T) in which an alternating current electric field is impressed between the developer carrying body 11 and the image bearing body 1 and a pause period (t) in which the AC electric field is not impressed, alternately.  In this case, the AC electric field is impressed so that, in a single operation period, a direction of a first electric field of the AC electric field and that of a last electric field are set to be the same, and in the successive operation period after the following pause period, a direction of a first electric field of the AC electric field is set to be the same as that of the last electric field of the previous operation period, and further a condition, 0.20<=T/(T+t)<=0.09, is fulfilled.

Title: Washer for window glass
Inventor: MURATA YUKIHO
IPC: B60S1/48
Filed: 1986-01-23
Abstract: PURPOSE:To ensure a required amount of washing by plural tanks, and remove the limitation of a configurational space for a washer tank, by disconnecting a tank, which has firstly consumed said washing, from a washer pump through a valve so as to prevent air suction. CONSTITUTION:Each capacity of a first tank 9 and a second tank 13 is set to about a half capacity of the whole required amount respectively, in order that they can be arranged in the comparatively small space of an engine room. And, when washing in the upper-level first tank 9 is consumed and gets to the predetermined level, a float valve 20 is operated so as to disconnect the connection to a washer pump 17. Therefore, the washer pump 17 can suck washing from the second tank 13 and exhaust it without sucking air from the tank 9. Also, when washing is replenished, the float valve 20 is operated to open as former time, so that the washer pump 17 can suck washing.

Inventor: KATOU OSAMU
IPC: B01D33/70
Filed: 1982-01-26
Abstract: PURPOSE:To provide a belt press type dehydrator which prevents leakage of sludge, etc. by constituting the same in such a way that the spacings between weir plates and a filter cloth belt can be changed according to the rate of supplying of the sludge passing between the weir plates and the filter cloth belt. CONSTITUTION:The sludge supplied onto a filter cloth belt 1 in front of a gravity dehydrating section is conveyed in the direction of an arrow 19, and is first passed under a rear baffle bracket 29, where the sludge is distributed in the transverse direction of the belt 1 by baffle plates 33a- and is passed as sludge ridge of penked shape 53a-. In the stage when the sludge raked like ridge passes under a weir plate 46, the sludge is crushed with the plate 46 to form a sludge layer of a specified thickness which is then ploughed over with the front baffle plates 33b- in succession thereto to expose the belt surface and to squeeze the sludge, whereby the moisture content of the sludge is decreased. Since the plates 46, 47 are held elastically turned and energized by spring plates 48, 49, the angles of inclination fluctuate according to the fluctuations in the atm. of the sludge even if said amt. fluctuates; therefore, the sludge is throughly dammed up and is prevented from overflowing.

Title: Distributing type fuel injection pump for internal combustion engine
Inventor: SAKURANAKA TOORU
IPC: F02M41/12
Filed: 1978-02-06
Abstract: PURPOSE: To provide a fuel injection pump for an internal combustion engine which can increase  the amount of fuel injection at the time of starting of the engine by constituting same such that  two separate cut-off passages which are provided within a plunger and connected to differently  positioned cut-off ports are alternatively brought into appropriate communication in accordance  with rotational frequency of the engine.   
     CONSTITUTION: At the time of starting of an engine, before a cut-off port 15b is disengaged  from a control sleeve 11 above its upper edge to be communicated to a suction spacing 4 of a  low pressure, it is brought out of communication with a fuel pressure feed passage 9 so that cut- off of fuel is not effected through the cut-off passage 15. Accordingly, fuel cut-off is not effected  until another cut-off port 14b which is always communicated to the fuel pressure feed passage 9  is brought into communication with the suction spacing 4. During rotation of the engine above  idling speed, while the cut-off port 15 remains communicated to the fuel pressure feed passage 9,  it is brought into communication with the suction spacing 4 earlier than the other cut-off port  14b, whereby fuel cut-off is effected through the cut-off port 15b.

Filed: 1992-01-27
Abstract: PURPOSE:To stabilize light outputs in a short time by calculating a lamp voltage during stable lighting from a measured time during which a lamp is turned off and a lamp voltage immediately after lighting, and controlling power supply to a discharge lamp according to the ratio of the lamp voltage of stable lighting to the current lamp voltage. CONSTITUTION:When a lighting switch 2 is turned on a control circuit 8 reads from a timer the time during which a lamp is turned off and reads from a current/voltage detection circuit 7 a lamp voltage immediately after lighting and retrieves a table to calculate the lamp voltage during stable lighting. The control circuit 8 then reads the current lamp voltage from the circuit 7 and retrieves the table to compute power supply required to set the light output to the same level as that of stable lighting. The circuit 8 then controls power supply to a discharge lamp 6 via a DC booster circuit 3-2 so that the light output is at the same level as the light output of stable lighting. Therefore, the light output is stabilized in a short time regardless of the time during which the lamp is turned off.

Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To damp an unsprung portion without sacrificing riding comfort and ensure road holding by setting a predetermined threshold value of the unsprung damping control portion to be relatively small when a detected value of the vertical behavior of the unsprung portion exceeds a predetermined value and a state of either abrupt braking or abrupt turning of the vehicle is detected. SOLUTION: At a normal running state of the vehicle, a damping force characteristic of each shock absorber b is controlled based on the vertical behavior of the sprung portion that has been detected by the sprung vertical behavior detection means c of a basic control portion d so as to perform a damping force characteristic control yet emphasizing good riding comfort of the vehicle. When the vertical behavior of the unsprung portion that has been detected by the unsprung vertical behavior detection means f exceeds the predetermined threshold value, and a state of either abrupt braking or abrupt turning of the vehicle is detected by the behavior change detection means h, the control is executed such that the predetermined threshold value of the unsprung damping control portion g is set to be relatively small.  Thus, the unsprung damping control is performed, emphasizing good riding comfort, thus improving grounding at abrupt braking or abrupt turning.
