Title: Control device of load sensing control hydraulic circuit
Inventor: TATSUMI AKIRA
IPC: F15B11/00
Filed: 1989-07-19
Abstract: PURPOSE:To set a target rotational frequency to low rotation so as to reduce fuel cost and noise by automatically increasing the rotational frequency of a prime mover when the discharge quantity of a hydraulic pump is saturated. CONSTITUTION:When a directional control valve 59 is set in the forward position and a pilot pressure reducing valve 58 is stepped in the condition where a setting device 68 sets a target rotational frequency smaller than the maximum rotational frequency of an engine 63, corresponding to the operation, pressure oil is supplied to a traveling motor 3. In the case where the load is comparatively small in low-speed running on a flat road, a control unit 40 conducts load sensing control in such a manner that the differential pressure between the discharge pressure and the running load pressure is constant. In case of conducting high speed running, when the demand flow of a flow control valve 4 is increased, and the discharge quantity of a hydraulic pump 1 is to be saturated, a target discharge quantity deviation is computed as a positive value, and the corresponding correction rotational frequency is increased while it is positive to increase the engine rotating speed. Thus, the target rotational frequency can be set to low rotation so as to reduce fuel cost and noise.

Title: Air duct with projection
Inventor: KATSUMATA TOMOHIDE
IPC: B41J29/377
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To provide an air duct with projections with which the assurance of high cooling efficiency is possible. SOLUTION: This air duct 11 with projections is installed near a fixing device (heat generating source) 9 and is constituted by projectingly providing the wall surface of a duct body 11a with >=3 projections 12 at approximately specified spacings S approximately perpendicularly to the flow direction of air. The arranging pitches S of the projections 12 are set according to the sectional shape of the projections 12.  The optimum value of the arranging pitches S of the projections 12 for assuring the high cooling efficiency of the air duct 11 with the projections varies with the sectional shape of the projections 12; for example, it is experimentally ascertained that the assurance of the high cooling efficiency of the air duct 11 with the projections is possible if the arranging pitches S of the projections 12 are set at 5H<=S<=13H when the sectional shape of the projections 12 is square.

Title: Data recording method and device
Inventor: KAGEYAMA MASAHIRO
IPC: G11B7/0045
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To improve the utilization efficiency at the time small consecutive free areas exist fragmentarily by changing over minimum recording lengths adaptively in accordance with whether a jump just after data access straddles a zone boundary or not and searching recordable areas being on a recording medium based on this straddling. SOLUTION: When a minimum recording length is to be determined in the condition that a buffer does not become empty in an readout, a revolving speed adjusting time is considered in the medium of a ZCLV system. When the first minimum recording length needed for access just before a jump which does not straddle a zone boundary and the second minimum recording length needed for access just before a jump which straddles a zone boundary are respectively set as D1, D2, they become to be D1<D2. In the case there are consecutive free areas equal to or longer than the second minimum recording length D2 in the zone wanted to be accessed, the areas are previously set as an intra-zone final recording area. Moreover, in the case there are consecutive free areas equal to or longer than the first minimum recording length D1, the area is addressed earlier.  After the final recording area is addressed, jumps are performed finally.

Title: Method and device for transfer of toner
Inventor: STAUDENMAYER WILLIAM J
IPC: G03G15/16
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To improve the transfer of a toner image of especially fine toner grains by moving a donor surface and a receiver surface so as to perform the transfer therebetween, while actively cooling the doner surface to the receiver surface. SOLUTION: A TECD(thermoelectric controll device) strip of a backup roller 28 is set to always cool an image member 21, whenever the strip enters a transfer nip 30, during operation. By this cooling the whole of the device is prevented from heating toner. Therefore, a surface 29 as 'the doner surface' is kept in a cooled state, while the toner image is first transferred to a surface 39. For further accelerating the transfer, the surface 39 can be slightly heated by the TECD of an intermediate transfer member. Thus, the toner is attracted to the surface 39 of the receiver surface, that is, an adapter surface and a temperature gradient for reducing sticking of toner to the donor surface, that is, the surface 29, is formed in the nip 30.

Filed: 1986-08-12
Abstract: PURPOSE:To obtain a thyristor with a high current breaking capability with a low cost and a high yield by a method wherein a recessed part is formed by etching with an insulating film as the circumference of a mask and an impurity is introduced into a segment part surrounded by the recessed part to form an emitter layer. CONSTITUTION:Gate etching-down of a silicon substrate 10 is performed with, for instance, mixed solution of fluoric acid and nitric acid by utilizing an oxide film 5 and a polyimide mask 7 as a mask to form a recessed part 6. After a P-type base layer 13 is formed by implantation and hot diffusion of boron ions, for instance, phosphorus ions 9 are implanted by utilizing the oxide film mask 5 and a resist mask 8 as a mask and, after the resist mask 8 is removed, an N-type emitter layer 14 is formed by hot diffusion. As the relative position between the emitter layer 14 and the recessed part 6 or the segment part surrounded by the recessed part 6 is always symmetrical and uniform, the bias and variation of gate impedance can be avoided and, moreover, a step for forming the oxide film can be eliminated.
