Title: Pulse emission controller and method for controlling emission of pulse light beam and aligner and exposure method and semiconductor device manufactured by the method
Inventor: MOTOISHI AKIRA
IPC: H01L21/027
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a pulse emission controller in which the failure of an image pickup means due to pulse emission can not be generated, and a load on a pulse light source can be reduced. SOLUTION: This pulse emission controller S2 includes a pulse light source 11, image pickup means 12, and reading control circuit. The pulse light source 11 emits a pulse light P1 to at least one of a photosensitive substrate 7 or a mask 4 on which a transfer pattern is formed as an objective site in an almost constant period. The image pickup means 12 reads an image signal SG1 obtained by receiving a reflected light or a transmitted light from the objective site. The reading control circuit controls the reading of the image pickup means 12 by starting the reading of the image signal SG1 of the image pickup means 12 after the end of the emission of the pulse light source 11, and ending the reading of the image signal SG1 before the next emission of the pulse light source 11.
Patent JP-H0417759-A (JP)
Title: Engine body
Inventor: GOTO TETSUAKI
IPC: F02F7/00
Filed: 1990-05-07
Abstract: PURPOSE:To improve the sealing characteristics of cooling water and oil by constituting an upper crankcase section with a bulkhead and a skirt section integral with a cylinder block, and a lower crankcase section with a ladder-like frame construction respectively for forming a crankshaft main bearing upper section on the lower surface of a bulkhead section between each cylinder. CONSTITUTION:A crankcase section 25 is horizontally divided approximately at the vertical center thereof. The upper crankcase section so made is constituted with a bulkhead 29 and a skirt section 26 integral with a cylinder block 21, while the lower crankcase section 41 is made to have a ladder-like frame construction. The main bearing upper section 43 of a crankshaft is thereby formed on the lower surface of a bulkhead positioned between each cylinder 22. When the crankcase section 25 is divided as aforementioned, the division does not come to the intermediate part of a water jacket 23. Regarding the lubrication of the main journal of the crankshaft, a division on the intermediate part of the water jacket 23 can also be avoided by forming an oil feed passage in the lower crankcase section 41. On the other hand, solid construction is available from a cylinder head 24 to the skirt section 26, and a vertical rib can be fitted without any discontinuity. As a result, the rigidity of the cylinder block 21 increases. Also, the rigidity of the skirt section 26 does not drop so much.

Title: Vehicular flicker
Inventor: MOKUYA HIROBUMI
IPC: B60Q1/26
Filed: 1980-08-26
Abstract: PURPOSE: To hold a relay contact in cutoff state in a simple connection by a method wherein the oscillation of an oscillation circuit is stopped by the conduction of a short-circuit detection transistor and the open state of the relay contact is held by the conduction of a self-holding transistor.  
     CONSTITUTION: When a short-circuit current flows through a resistance 201, a transisor 202 is ON and the detected signal is supplied through a diode 211 to the point between the resistance 106 of the oscillation circuit means 100 and the plus terminal of a capacitor 109 to turn OFF transistors 101 and 102 and as a result a relay coil 10 is disenergized to open the relay contact to cutoff the short-circuit current. When the short-circuit current is cutoff, the current flows in turn through the transistor 202, resistances 207 and 208 and a diode 210 to turn ON a transistor 206. Under the condition as described above, the transistor 202 remains to be ON after the cutoff of the short-circuit current and continues to supply the short-circuit current detected signal. On the other hand, the oscillation circuit means 100 holds the short-circuit current in cutoff state during the time that the signal is being supplied.

Title: Method for purifying acrylic acid
Inventor: SHIMIZU NOBORU
IPC: C07C67/00
Filed: 1982-07-08
Abstract: PURPOSE:To purify acrylic acid in high yield without causing trouble due to by-products in catalytically oxidizing propylene or acrolein in the vapor phase, by adding a bisulfite to an aqueous solution of the acrylic acid free from light boiling substances, and extracting the acrylic acid. CONSTITUTION:Propylene or acrolein is catalytically oxidized in the vapor phase to prepare acrylic acid. In the process, an aqueous solution obtained by cooling and condensing a product gas, emerging from an oxidation reactor, and containing the acrylic acid is first subjected to the distilling or stripping operation to remove light-boiling substances. 0.5-15wt% bisulfite, e.g. an alkali metallic salt or ammonium salt, is then added to the resultant aqueous solution, and then the acrylic acid is extracted therefrom to purify the acrylic acid. EFFECT:By-products are easily separated and removed in the extraction, and the separating state of the interface is improved. The occurrence of polymers and scales in distilling the extract solution is remarkably reduced.

Filed: 1989-05-11
Abstract: PURPOSE:To improve a dynamic SINAD characteristic by providing an electric field strength comparison means having a prescribed hysteresis width and sending a selection control signal of an average level of a received electric field strength and varying continuously the switching width of a control signal corresponding to the received electric field strength. CONSTITUTION:Inputted levels of two envelopes are compared by a comparator 61 and when a control signal is sent at a point (a) of an output level 30, the control signal is again sent when the level reaches a point 15. When a control signal is sent when an output level reaches a point a', the control signal is sent again at a point b'. That is, the comparator 61 is operated with a large switching width when the input level is high and with a small switching width when the input level is low and the switching width is varied consecutively. Thus, the changeover of diversity by the switch 41 is suppressed when the reception electric field level is high and the changeover is implemented positively when low, then the dynamic SINAD characteristic at a strong reception electric field level is improved.
