Inventor: OKUBO TAKASHI
IPC: G03F1/22
Filed: 1992-05-19
Abstract: PURPOSE:To position a. mask and a mounting frame with high accuracy and with good reproducibility when the mask is bonded to the mounting frame and to bond the mask to the mounting frame without causing any deformation in a mask substrate. CONSTITUTION:The title bonding apparatus is provided with the following: mask holding mechanisms 12, 13 which hold an X-ray mask 16; and a mechanism 17 which aligns the mask 16 with a mounting frame 4. The title bonding apparatus is constituted in the following manner: the X-ray mask is positioned and set by using a pattern 31 formed on the absorber of the X-ray mask 16; and, in this state, the X-ray mask 16 is bonded onto the mounting frame 4 by using an adhesive 5. An elastic body 14 is interposed between the mask holding arm support mechanism 12 and the mask holding arm 13 which constitute a mask holding mechanism so that a shock force is reduced when the X-ray mask 16 comes into contact with the mounting frame 4. In addition, the mask holding arm 13 is held when it is aligned before the X-ray mask 16 is bonded, and only one part of the mask 16 is sucked. Thereby, a mechanical force acting on the mask 16 when it is bonded can be reduced, and an unbalanced force which deforms the mask 16 does not act.

IPC: H04L7/033
Filed: 1979-11-22
Abstract: PURPOSE:To increase the effect of jitter compression, by controlling the output clock of a phase control circuit at leading and trailing point of input data. CONSTITUTION:The 0 phase clock nBc is fed to a shift register 13 constituting a frequency divider. When the input data 101 is input to FF1, the pi phase clock nBc is transferred to the shift register 13 at an earlier time from an AND circuit 18, and control is made so that the advance is made by a half phase of the pi phase after the conversion point of input data, allowing to cause the effect of compression by this share. The trailing pulse of the input data 101 is compared with the clock 116 of the register 13 and the AND circuit 17 to obtain the clock which is delayed by a half phase of the pi phase at the trailing and leading points of the input data at the output of an NAND circuit 10, and delayed clock is obtained at the terminal Qi frequency-divided.

Title: Current supply control device for fuel sensor of internal combustion engine
Inventor: AIZAWA HIROYUKI
IPC: F02D19/08
Filed: 1990-06-12
Abstract: PURPOSE:To shorten current supply time while detecting fuel composition to restrain deterioration by providing a current supply control means to supply current to the electrode of a fuel sensor, when it is judged the remain quantity of fuel is increased and air-fuel ratio is varied over a prescribed value. CONSTITUTION:When the remaining quantity of fuel in a fuel tank is increased, and when the fuel remaining is increased and air-fuel ratio feedback correcting coefficient (corresponding to air-fuel ratio) during air-fuel ratio feedback control is varied on rich side or lean side over a prescribed value, current is intermittently supplied to an alcohol concentration sensor 5, because alcohol concentration is detected by supplying current to the sensor 5. It takes about two or three minutes from start to air-fuel feedback control, and alcohol concentration can be detected by supplying current to the sensor 5 for about one to three seconds. Consequently, current supply time for the sensor 5 is remarkably shortened to detect alcohol concentration and hence galvanic corrosion of the electrode of the sensor 5, deterioration of the sensor 5 can be restrained.
