Title: Alignment mark
Inventor: KATO MASAAKI
IPC: H01L21/027
Filed: 1991-05-16
Abstract: PURPOSE:To provide an alignment mark with which alignment operation is observed with low magnifying power and the alignment is brought into focus easily when a wafer is aligned with a photomask in a photo-lithography process for a semiconductor manufacturing process. CONSTITUTION:Each rectangular recessed section 1a is formed at intervals of 9mum in a mark 1 of a wafer while each rectangular recessed section 2a is formed in a mark 2 of a photomask at intervals of 10mum. In this case, since each lateral line 1p or 2p of the recessed section 1a or 2a is considered as a graduation, the mark 1 has a vernier pattern in shape with respect to the mark 2. Then, alignment can be adjusted only by putting one of the lateral lines of the recessed part 1a in accord with that of the recessed part 2a, and thereby an error value in location can be obtained. Consequently, alignment operation is observed with low magnifying power and the alignment is brought into focus easily so that the accuracy in alignment can be improved.

Title: Charging port device for empty can press
Inventor: KASHIBE JIROU
IPC: B30B9/32
Filed: 1983-06-23
Abstract: PURPOSE:To make charging of a can easy and to maintain safety by constituting a titled device in such a way that a charging port is kept always open in such a way as to prohibit insertion of hand into the machine body. CONSTITUTION:An empty can K is charged into a sleeve 11 of which a discharging port 11b is held closed by a cap 24. When the sleeve 11 is turned toward the arrow and is held upright, a roller 23 disengages from a guiding part 33 and a working bar 18 is moved upward by a pull spring 19. The bar 18 is then detained to an engaging part 34 by the roller 23 to hold the sleeve 11 in an upright state. On the other hand, the cap 24 is released from the bar 18 and is reset to the home position by a spring 26 and therefore the can K in the sleeve 11 is dropped into a pressing section 3a. A releasing element 35 is lifted by the roller 23 to turn on a start switch 38. A press device 3 is operated by the turning-on of the switch to start pressing the can K.

Title: Language learning tool
Inventor: HAYAMA YOSHIO
IPC: G09B19/08
Filed: 1992-04-06
Abstract: PURPOSE:To master the rhythm and intonation of a foreign language while visually confirming them by varying the size of characters corresponding to the strength of accent and varying intervals between words corresponding to the time required for pronunciation, and then displaying the words. CONSTITUTION:A display 3 is printed on a base body 6; and the largest letter 'i' where a 1st word stress is placed in a word 4 'bigger' where a 1st sentence stress is placed is displayed and small letters 5 'for' where no stress is placed are displayed. Therefore, the part which is displayed large is only pronounced strongly and the part which is displayed small is pronounced weakly. The time required for the pronunciation is also visually represented, so the word 4 like 'bigger' where the 1st sentence stress is placed is pronounced slowly, so the word is displayed at a larger interval with a following word and the word 5 like 'for' where not stress is placed is displayed closely to a precedent word. Therefore, when the words are pronounced, a pause is placed at the part where the interval between the words is wide and the words are pronounced without any pause at the part where the interval is narrow.

Abstract: PURPOSE:To improve the cleaning effect by moving mechanically a remaining developer stuck to a recording material simultaneously with light irradiation to the recording material to weaken the attraction between the recording material and the remaining developer and removing the remaining developer easily with a blade. CONSTITUTION:After a developed image on a recording material is transferred to a recording paper and the recording paper is separated from the surface of the recording material 1, a remaining toner is moved in the direction of an arrow B orthogonal to the advance direction of the recording material 1 by a brush 13 of a developer sweeping-up member 12 when the surface of the recording material 1 to which the remaining toner is stuck reaches a cleaning device 2. Meanwhile, a part E to which the remaining toner is stuck is irradiated by light L because the surface of the recording material 1 is irradiated by an irradiating device 7. That is, the electric charge is removed from not only parts to which the remaining toner is not stuck but also parts to which the remaining toner is stuck on the surface of the recording material 1. Therefore, the attraction between the recording material 1 and the remaining toner is weakened to about zero, and the remaining toner is removed easily by a blade 6 when the surface of the recording material 1 to which the remaining toner is stuck reaches the blade 6.
