Title: Pack-and-pinion type steering system
Inventor: TASHIRO TAKASHI
IPC: B62D3/12
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components of a rack-and-pinion type steering system and facilitate their assembly. SOLUTION: A rack support member 16 is reciprocatingly inserted, in a holding bore 15 in a housing 5 that encloses a rack 7 meshing a pinion 6. By the rotation along the reciprocating direction a closure member 18 is screwed in the housing 5 to hold a compression spring 24 between itself and the support member 16 which is adapted to close one end opening of the bore 15. The rack 16 is, however, restricted in rotation on the axis in its reciprocating direction with respect to the rack 7, and so is the rack 7 to the housing 5. The spring 24 is coupled at its one end to the support member 16 also against its rotation on the axis in its reciprocating direction. The closure member 18 is meshed with the other end of the spring 24 for its rotation in its screwing direction into the housing 5 and against its rotation in its unscrewing direction.

Title: Flow rate controller
Inventor: KATOU TOSHIYA
IPC: B62D5/07
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a drooping characteristic by means of a small number of parts by forming a throttle, whose opening is varied according to a pressure difference between the front side and the rear side of a fixed throttle, of an elastic member in a flow path through which working fluid passes the fixed throttle is led to a discharge hole. SOLUTION: When a rotational speed of a pump is raised and a discharge flow rate of working fluid is increased, a flow rate of the working fluid passing a fixed throttle 31 is increased, and consequently, a pressure difference between the front side and the rear side of the fixed throttle 31 is also increased because of flow path resistance in the fixed throttle 31. A pressure based on the pressure difference is led to a pressure chamber 49 via a pressure introducing hole 41, and by means of a pressure generated in the pressure chamber 49, an elastic member 47 is elastically deformed toward the inside of a flow path 23. Then, a projection part 44 formed in the elastic member 47 is also deformed inward, and an opening area of a throttle 24 is reduced, and as a result, the working fluid fed to a power steering device is also reduced.

Title: Vehicle accelerator pedal device
Inventor: KATO YASUNARI
IPC: F02D11/04
Filed: 1993-10-29
Abstract: PURPOSE:To secure a good driving property in all ranges of accelerator operating amount and to make the accelerator pedal return for certain, even if returning force added to the accelerator pedal has reduced, by multiplying hysteresis characteristic between the accelerator operating amount and the stepping-down strength in accordance with the accelerator operating amount. CONSTITUTION:A No.1 rotor 11 rotates in one unit with a rotary shaft 5 and causes an accelerator pedal to generate its returning strength by giving deflection to springs 15, 17 sandwitched between a No.2 rotor. Steel ball grooves 43, 45 to axially support a steel ball 41 is formed obliquely on the end surfaces where No.2 rotor and a stopper 47 face each other. As the return strength increases, the steel ball grooves 43, 45 start to face each other at their shallow areas. Thus pressure applied to a rotary shaft side friction plate 27, which rotates in one unit with the rotary shaft 5, and to a housing side friction plate 29, which is fixed to a housing 7, increases and mobile drag corresponding to the returning force is impressed.

Title: Reader for optical digital data
Inventor: TSURUOKA YOSHIAKI
IPC: G06K7/10
Filed: 1985-12-03
Abstract: PURPOSE:To obtain a reading signal which can recognize the correct position of a data pit to be read and has a uniform pulse width by providing an AND gate to obtain and output the 'or' of the output logical signal of a comparator and a peak detecting device and a pulse generating device to generate the pulse with a prescribed width synchronized to the output signal. CONSTITUTION:A peak detecting device 6, for example, uses a differentiation circuit, differentiates a signal Q, obtains a differentiation signal T, detects the zero level and obtains a peak detecting signal U. This comes to be the output binary signal of the peak detecting device 6 and the high level position corresponds to the peak position of the signal Q. Next, in an AND gate 7, by obtaining the 'or' of a signal S and the signal U, the pulse corresponding to the minimum peak included in the signal U and the pulse corresponding to the peak of a noise component to appear between data pits can be removed. Consequently, the output signal of the AND gate 7 comes to be a signal V. By triggering a one shot multivibrator 8 with the pulse of the signal V, a final reading signal W is obtained.

Abstract: PURPOSE:To obtain a high precise and high tough protective layer which is efficient in mass productivity by a method wherein a protective layer is composed of a compound containing, at least, Si, Zr, N, O or a compound containing this compound plus, at least, Y. CONSTITUTION:A thermal head is equipped with a high resistant substrate, a thermal resistor layer provided on the high resistant substrate, an electrode layer provided on the high resistant substrate electrically connected to the thermal resistor layer, and a protective layer covering a heating part of the thermal resistor layer.

An additional amount of Y2O3 is about 0.1 to 10mol% and that of ZrO2 is about 1.0 to 40mol%. When Y2O3 and ZrO2 are respectively at most 0.1mol% and 1.0mol%, sufficient hardness and toughness can not be obtained. Further, when they are respectively 10mol% or over and 40mol% or over, a considerable amount of Y and Zr comes to exist as metal components in the protective layer, and an insulating property of the protective layer is impaired. The protective layer has no decrease of a sputtering rate and is efficient in mass productivity. Though toughness is increased by Zr and Y, decrease of the insulating property thereby is little.
