Title: Method and apparatus for ink jet recording
Inventor: GOTOH FUMIHIRO
IPC: B41J2/21
Filed: 1993-01-08
Abstract: PURPOSE:To improve reliability when at least one of a plurality of kinds of ink becomes hard to eject steadily in a recording with a plurality of inks in different densities in the same color by a method wherein the printing is continued with the ink of the remaining kinds. CONSTITUTION:In the ink jet recording method described herein, a carriage 501 is equipped with an ink jet unit comprising a plurality of ejecting port arrays that eject inks in black, cyan, magenta and yellow, each of which is in two different densities. Heat-generating elements incorporated in the ink ejecting ports are driven on recording signals in accordance with timing read by an encoder, and images are formed on a material on which recording is made with ink drops ejected in a sequence, in which the ink in high density comes first and the ink in low density comes next. In the case where a judgement is made that at least one kind of ink becomes unable to be ejected steadily, the rate of use of each of a plurality of inks determined by a distribution device is changed, and the recording is continued with the inks of the remaining kinds.

The density of each of plural formed reference toner patches is detected (step S7). Correlation between the density and the image forming condition is obtained from the density of each of plural reference toner patches and the image forming condition at the formation of the reference toner patch, and the image forming conditions such that the density becomes a prescribed density decided from the obtained correlation (step S8).

Title: Brake gear for automobile
Inventor: KOTANINO SADAYUKI
IPC: B60T11/10
Filed: 1980-01-12
Abstract: PURPOSE: To apply the optimum brakes by a method wherein front wheels are braked by each or the combination of two lines of inputs, tread and grip, through a brake valve controlling the two lines and it makes possible to receive the two lines of inputs with a flexible pipe.  
     CONSTITUTION: Oil pressure is generated in a master cylinder through a grip input F 2  and propagated to an oil chamber B of a brake valve 22 through a flexible pipe 43. When the input F 2  is increased, the pressure in the oil chamber B becomes larger and a slide valve 33 is let to move right against a spring 30. When the valve 33 closes a port F, pressure is generated in a chamber D and it is propagated to front caliper type brakes 5A, 5B. Pressure is generated in a master cylinder 16 by a tread input F 1 , is propagated to a rear caliper type brake 14 through a pipe 18 and to an oil chamber A of the brake valve 22. Thus, slide valves 53 and 33 move right, pressure appears in the chamber D and propagates to the caliper type brakes 5A, 5B. When the tread F 1  and the grip F 2  are operated, the combination of them moves the valve 33 rightward, a higher pressure is created in the chamber D and propagated to the front caliper type brakes 5A, 5B in like manner.

Title: Working vehicle running transmitting structure
Inventor: HAMA MASAAKI
IPC: B60W10/10
Filed: 1990-01-09
Abstract: PURPOSE:To lessen shocks at the time of starting etc. by furnishing an accumulator equipped with No.1 spring, which gives resistance to a piston moving in its whole stroke, and No.2 spring which gives resistance only in the later half of the piston stroke. CONSTITUTION:On a working oil supply path 20 a throttle part is installed in parallel connection with No.1 opening/closing valve 21 and No.2 opening/ closing valve 27, wherein the No.1 valve shuts when the secondary side oil pressure reaches No.1 set value while the No.2 valve opens when the same pressure attains No.2 set value. When the pressure of an oil pressure clutch 3 reaches the mentioned No.1 set value to shut the No.1 opening/closing valve 21 which is open normally, the pressure boosts gradually, and a resistance given only by No.1 spring 31 acts on the movement of a piston 35 in an accumulator 23. Because this resistance is weak, the pressure rise is gradual, but when the piston 35 attains the specified position, resistances of No.1 spring 31 and No.2 spring 33 act simultaneously to quicken the rise of the pressure. Thus shock is lessened because of decreasing difference in the boosting degree between this quickened pressure rise and the pressure rise after the No.2 valve 27 opened.

Title: Pulse train distributing circuit
Inventor: NAGAI TETSUYA
IPC: H03K5/00
Filed: 1987-01-08
Abstract: PURPOSE:To prevent the change of the total number of pulses even if the output destination of pulses is changed at an arbitrary time, by using plural edge trigger monostable multivibrators with enable function and taking notice of only edges of input pulses to detect pulses. CONSTITUTION:The input pulse is applied to clock terminals of edge trigger monostable multivibrators 11 and 12 with enable function. A control signal is applied to the enable terminal of the vibrator 12 and is applied to that of the vibrator 11 after inverted by an inverter 13. If the control signal is '0', an output pulse appears in the vibrator 11 but does not appear in the vibrator 12. If the control signal is '1', output relations are inverted. The pulse is detected with only the leading edge of the input pulse by this constitution, and the number of pulses is not different between input and output even if the output destination of pulses is changed at an arbitrary time.

Abstract: PURPOSE:To prevent the occurrence of abnormal vibrating noise effectively, by fastening and securing the brackets to block both ends of a frame with a stud bolt having grade difference in outside diameter. CONSTITUTION:Brackets 12 and 13 to block the openings on both ends of a frame 11 are fastened and secured with a stud bolt 14 through a nut 15. A through a passage section 16a is formed through which the stud bolt 14 passes in releasably inserted condition to a stator core 16 provided in the central part sinside the frame 11. When a rotary electric machine is driven with an inverter, the natural vibration frequency of the stud bolt 14 is raided as it is made in different diameters as in the large diameter part 14a and the small diameter part 14b, and that the small diameter part 16b inside the through passage section 16a of the stator core 16 is not in contact with the stator core 16. No stud bolt 14 will therefore come to resonate with the carrier frequency of the inverter and the occurrence of abnormal vibrating noise caused by the resonance of the stud bolt 14 can be prevented.
