Title: Magnetic recording and reproducing device
Inventor: YONEDA KOUJI
IPC: H01L41/09
Filed: 1982-12-29
Abstract: PURPOSE:To make an alignment of head height in recording without any hindrance by detecting the difference in electrostatic capacity between an electrode and an electrode plate and then displacing an electromechanical transducing element so that the difference in electrostatic capacity is eliminated. CONSTITUTION:An output voltage eA obtained by a block 22 according to the electrostatic capacity formed by a piezoelectric element equipped with a head A and an electrode plate is compared by a comparator 23 with an output voltage eB obtained by a block 22' according to the electrostatic capacity formed by a piezoelectric element equipped with a head B and an electrode plate, obtaining a voltage corresponding to the potential difference. This voltage is inputted to a driving circuit 24 to displace the piezoelectric element 7. Consequently, the potential difference, i.e. electrostatic difference is eliminated. Namely, rotary magnetic heads 8 and 8' provided to the piezoelectric elements 7 and 7' are held at the same relative height. Thus, an alignment of head height in recording is made without any hindrance.

Title: Member
Inventor: SHONO NOBUHIRO
IPC: A47K3/02
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To lessen adhesion of water and to let the surface have low water adhesion and reduce dirt of the surface by providing stripe-like very fine projecting and recessed parts in an arbitrary direction on the surface of a member and arranging the projecting and recessed parts to alternate with a hydrophilic surface and a water repellent surface. SOLUTION: A smooth tile for interior and a metal plate are stacked in such a manner that the tile is on the lower side and the metal plate is on the upper side, and alumina abrasives 0.5 micron is put between them. The tile is fixed, while applying a load to the metal plate, it is slowly moved in the direction of the side to form a very fine stripe-like projecting and recessed surface on the tile. Thus, water adhering to the member is easy to flow down along the stripe so as to reduce evaporation residue in water, and as water is little, breeding of bacteria can be restrained. The stripe-like fine projecting and recessed parts are arranged to alternate with a hydrophilic surface 2 and a water repellent surface 1.  Thus, water adhering to the water repellent surface 1 is repelled to be captured by the hydrophilic surface 2, and the collected water becomes a drop to drop along the stripe, so that adhesion of water causing dirt can be reduced.

Title: Mounting structure of cover body
Inventor: WATANABE YOKO
IPC: B60R19/04
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To secure the extent of required locked strength by engaging a part out of plural pieces of locked claws with a guide receiving part in a state of being elastically deformed in the specified direction and the other locked claw in a state of being elastically deformed in the opposite direction, respectively. SOLUTION: Locked claws 22a and 22c of a mask 21 is locked with end edges 13a and 14a of adapter plate parts 13 and 14. Since a length of these locked claws 22a to 22c is longer than that of guide pieces 23a and 23b, a tip locked part of the locked claw 22b is inserted into a square hole 14b prior to these guide pieces 23a and 23b, and this tip locked part is pressed by a side face of the square hole 14 and thereby it passes through therefrom as being elastically deformed. Successively these guide pieces 23a and 23b are inserted into square holes 13b and 14c. Since each projecting position of these guide pieces 23a and 23b is dislocated left and right from the center of these square holes 13b and 14c and the side face is inclined, this incline presses an end face of the square hole 14c, shifting a notch part 12 to some extent.  The guide piece 23b also acts likewise, contracting a range of width W1 of this notch part 12. Accordingly, clearance between the locked claws 22a to 22c and the adapter plate parts 13, 14 and the respective end edges of notch part 12 is gone, and thus the extent of large locked strength is secured.
