Abstract: In an automatic transmission 16, clutch-to-clutch closed throttle downshifting is controlled by filling the on-coming clutch C1-C5 at a maximum pressure command for a set period while commanding the off-going clutch pressure to a low value and exhausting the off-going clutch C1-C5 before the end of the fill period. At the end of the fill period the on-coming pressure is set to an initial value and then ramped up until turbine speed Nt is pulled up due to off-going clutch slippage. Then a closed-loop profile control period starts wherein the slip of the on-coming clutch C1-C5 is measured and controlled to a slip profile. When synchronization of the on-coming clutch is detected, maximum pressure is commanded. Parameters for controlling the quality of a shift such as on-coming clutch initial pressure and on-coming clutch fill time are automatically adjustable during vehicle use to correct shift aberrations which degrade shift quality.

Abstract: A convergence measurement apparatus for a colour CRT (1) comprises a light sensor (4) which is placed on the screen (2) of the CRT (1) to be tested, a CPU (8), and a pattern generator (15) which causes a plurality of luminescent lines of a primary colour to be displayed on one area (S₁) of the screen (2) and a plane area which is a composite of the two other primary colours to be displayed on another area (S₂) of the screen. The lines are shifted at a given rate along the designated area (S₁) of the screen (2), the colour of the displayed lines successively changing to each primary colour. The light sensor (4) receives light intensity information from the generated pattern and the CPU (8) calculates a mis-convergence value based on the light intensity data. The apparatus further includes a self-inspection feature by which the processing is executed for successive measurements of the same primary colour. If the values for each measurement are identical, the system is assumed to be operating normally, but if there is variation, abnormal operation can be diagnosed.

Abstract: Disclosed are a two-component type developer which is supplied to an area where a bias voltage of at least 250 V is applied, and a developing process using this developer. In this developer, by adjusting the particle size distribution of carrier particles within a specific range, occurrence of the so-called carrier dragging phenomenon of the transfer of the carrier together with the toner to a photosensitive material can be prevented. This adjustment of the particle size distribution is such that the content of carrier particles having a size smaller than 250 mesh is less than 8% by weight based on the entire carrier particles, the diameter D₅₀ of the weight average particle size corresponding to 50% of the weight of the entire carrier particles is in the range of from 80 to 120 µm and the difference between D₂₅ and D₇₅ is in the range of from 5 to 20 µm.

Abstract: In a bending press in which a slider (15) is displaceable by means of hydraulic drive devices comprising jacks (1, 1') disposed on the sides of the slider and coupled with means of detecting the position and speed of the slider, the displacement of the slider is measured in a given time or over a given distance starting from a stop position reached after a movement interrupt command, in order to determine possible abnormal leakages in the hydraulic devices. Furthermore, there is an independent comparison between the stop time or distance of each of the jacks with reference values in order to detect symmetry faults in the drive devices.

Abstract: In infrared emitters, whose resistance wire is located in a sheathing tube of quartz glass or fused silica, radiant losses can be reduced by means of a reflection layer, for example of gold, located on the sheathing tube. To improve the thermal stability of the reflection layer, a protective coating of zirconium dioxide, silica and/or tin dioxide is proposed. The protective coating can be produced by using thermally decomposable organic compounds of zirconium, silicon and/or tin.

Abstract: In a sealed and pressurized housing (10), the TV camera is mounted on a cradle (12) which includes the sealing mechanism for both ends of the housing. Both ends (18,28) are sealed with conventional "O" ring seals (22) and end plates (24,34) which are secured to the cradle. Since pressure is always equalized against both end plates and they are mechanically connected, when the housing is opened, no parts can be dangerously propelled upon release of the pressure. The cradle is also mounted so that, despite the internal pressure, it can be rotated relative to the fixed outer casing in order to adjust the angle of the camera to the horizontal.

Abstract: In a rendezvous manoeuvre for approaching a rendezvous spacecraft to a target spacecraft via a reference trajectory (ℓ) for approach which is different in altitude and period from the trajectory of the target spacecraft, if the rendezvous spacecraft is deviated from the reference trajectory for approach as a result of , for instance a failure in the manoeuvre, it is first manoeuvred in the direction of altitude after 0.2 revolutions, and then manoeuvred in the direction of phase after another 0.2 revolutions. The rendezvous spacecraft is thereby restored to the reference trajectory without entering a collision course, so that a highly reliable retry/recovery may be performed promptly and safely.

Abstract: An output circuit for a memory device has four MOS transistors. A first MOS transistor (M1) and a second MOS transistor (M2) comprise an output stage of the output circuit, and a control circuit controls the voltages of the gates of the first and the second MOS transistors (M1, M2). A third MOS transistor (M3) has its source connected to the gate of the second MOS transistor (M2), and a fourth MOS transistor (M4) has its source connected to the gate of the first MOS transistor (M1). When the data which are supplied to the control circuit are changed, the third or the fourth MOS transistor (M3, M4) assists the level shift of the gate of the second and the first MOS transistor (M2, M1) at the beginning of the level shift. By continuing the level shift, the third or the fourth MOS transistor (M3, M4) is turned off. As a result the source-gate voltage of the third or the fourth MOS transistor (M3, M4) becomes lower than its threshold voltage, so that the switching noise or ground noise is reduced.

Abstract: An automatic equalizer includes an adaptive matched filter (302) connected in front of a decision feedback equalizer (301) of a conventional design. The adaptive matched filter has an A/D converter (12) for sampling and quantizing an analog baseband signal into a digital signal, which is applied to a transversal filter (103). The transversal filter is supplied with tap coefficients adaptively controlled by a control signal generator (104) which makes automatic adjustments to symmetrize the impulse response of a transmission path depending on the status of fading. The automatic equalizer can sufficiently equalize the fading in the range ρ > 1 in which the reflected wave is stronger than the direct wave, which fading cannot be adequately equalized only by the conventional decision feedback equalizer (301).

Abstract: In order to improve rigidity and stability, shorten a whole length, reduce the number of component parts and assembling steps in an inscribed meshing planetary gear construction, a flange part 114 of an output shaft 102, inner pins 107 and support ring 117 are supported at both ends by bearings 115a and 115b, and then a reduction mechanism part is assembled between bearings 115a and 115b. Axial position of the inner pins 107 are set by inner rings 124a and 124b of the bearings 115a and 115b. Subsequently, with respect to inner pins 107, it is not necessary to provide any shoulder or treading, and the shape is allowed to be simplified, so that machining for high hardness and high accuracy can be realized at low cost, and then a predetermined quality can be secured together with both supporting structures without requiring any expensive inner rollers. This constitution can also be applied in the epicyclic gear construction having a carrier pin 116.
