Title: Mask for x-ray exposing
Inventor: SAWADA RYOZO
IPC: G03F1/00
Filed: 1985-05-09
Abstract: PURPOSE:To obtain a stable mask for X-ray having a fresh base film by using a diamond-like carbon film or composite laminated film consisting essentially of the diamond-like carbon film as an X-ray transmittable base film and forming an X-ray absorptive material pattern thereto. CONSTITUTION:A 2'' silicon wafer is used and diamond-like carbon is formed to about 0.5mum thickness by a magnetron sputtering method using a graphite target onto such substrate. A Ta film is formed on the surface thereof again by sputtering and after a fine pattern is formed thereon, an X-ray mask is formed by back etching, by which <=0.1mum accuracy of the pattern position in a packaged state is realized and the result of the contrast in the stage of exposing as good as 22 is obtd. The base film has a small coefft. of X-ray absorption and high mechanical strength and therefore the relatively thin construction is possible if such base film is used and the use of heavy metals or the compds., etc. thereof over a wide range as an X-ray absorption pattern material is made possible.

Title: Heat exchanger
Inventor: SUNAHATA TAKUMI
IPC: F25D21/08
Filed: 1989-04-17
Abstract: PURPOSE:To allow condensed water during defrosting to avoid coming in contact with a radiant heater without needing a cover for preventing heat release of the radiant heater by providing cutouts at an adjacent part of the radiant heater arranged downward of a fins. CONSTITUTION:A cutout 11 is formed in the lower end part of a fin 1 divided to constitute a specified row pitch. Heat exchange is performed between a current (A) flowing among fins 1 and a heating medium flowing in heating medium pipes 2. At that time, water vapor in the current (A) is frozen to become frost and attached to the surface of a heat exchanger. In order to remove the frost, by heating a radiant heater 3 the frost becomes condensed water to flow down along the cutouts of the fins 1 and is dropped in righthand and lefthand sides to avoid the radiant heater 3. Thereby, the condensed water dropping without attachment of a cover can avoid coming in contact with the radiant heater.

Title: Drive system clutch control device for vehicle
Inventor: IMAZEKI TAKASHI
IPC: B60K17/348
Filed: 1986-04-26
Abstract: PURPOSE:To optimize the clutch tightening control by estimating the road friction coefficient based on the drive torque and the change quantity of the drive shaft rotating speed difference and using this road friction coefficient as the correction factor for controlling the increase or decrease of the clutch tightening force. CONSTITUTION:First, the rotating speed difference from a rotating speed difference calculator 431 is read and differentiated to obtain a rotating speed differential value. On the other hand, the drive torque from a torque sensor 33 is read, and the road friction coefficient is table-looked up based on it and the rotating speed difference differential value. The correction coefficient for controlling the increase or decrease of the clutch tightening force can be obtained based on this road friction coefficient. For example, the rotating speed difference between the front and rear wheels is readily generated on a low-friction coefficient road such as a rainy road, thus the correction coefficient becomes a high value, on the contrary, it becomes a value near 1 on a high-friction coefficient road such as a dry asphalt road. Accordingly, the optimum clutch tightening force control in response to the road friction coefficient can be performed.

Filed: 1980-07-17
Abstract: PURPOSE:To obtain the information about the amount of unbalance that is always stable and informaion about phase from unbalance signals even if revolution of a rotary body to be measured varies, by using a digital; filter provided with a prescribed transfer function. CONSTITUTION:A tire 4 to be measured is rotated via a motor 5, etc., and unbalance signals of the faces 4a, 4b of the tire 4 are detected with vibration detecting elements 11, 12 provided on bearings 2, 3.

At the same time, with the execution of inpulse response of a filter function and convolution, a signal proportional to amplitude and phase of the amount of unbalance is generated. In that case, when a transfer function of each of the filters 18, 19 is selected such that it satisfies a formula I where each coefficient becomes a constant with respect to the sampling time interval T, unbalance information that is always stable is obtained even if revolution of the rotary shaft varies.
