Title: Manufacture of semiconductor laser
Inventor: IKUTA AKIHISA
IPC: H01S5/00
Filed: 1986-09-16
Abstract: PURPOSE:To realize an excellent characteristic with respect to a high output level, a basic horizontal mode and a low threshold electric current by a method wherein, after an inversely structured mesa has been formed by etching using a bromine methanol solution, a clad layer at the lower part is etched to form a stripe by means of hydrochloric acid so that the second epitaxial growth can be made. CONSTITUTION:During the first liquid phase epitaxial growth, a stripe-like pattern with a <001> crystal orientation is formed on a flat N-type InP substrate 6 in such a way that a lattice is aligned in succession, and, by means of etching using a bromine methanol solution, an active layer 4 with a width of about 2 mum is formed at the position where an inverted mesa shows the minimum width. After that, by using a mixed solution which is composed of one part of hydrochloric acid and two parts of phosphoric acid, an N-type InP layer 5 is etched almost vertically (about 2.5 mum). Then, during the second liquid phase epitaxial growth, the first buried P-type InP layer 8 is grown to the height of the active layer 4, and, after that, the second buried N-type InP layer 7 is growth. After the pattern of an SiO2 film 1 has been removed, an electrode part is formed.

IPC: H01P5/02
Filed: 1986-09-16
Abstract: PURPOSE:To attain a wide frequency band transmission by providing a fixed part composed of a fixed disk on which a microstrip line is formed on a circle so that said fixed part can face the microstrip line formed on the rotating disk. CONSTITUTION:The oscillation frequency of an oscillation circuit 232 connected to the microstrip 216 at a fixed side, which is electromagnetically linked with at closed-loop-like microstrip 215 at a rotating part side, changes according to the resonance frequency of said strip 215. The change in the oscillation frequency of the oscillation circuit 232 is detected by a demodulator circuit 222 selectively connected to the closed-loop-like microstrip 215 at a rotating part side, whereby a recording video signal is demodulated. Namely, the recording video signal is transmitted to the rotating part side from the fixed one, and recorded on a magnetic tape by a rotating magnetic tape. Thus a signal transmission characteristic in an extremely wide frequency band can be obtained.

Abstract: PURPOSE:To obtain the titled head whose characteristic is not deteriorated even when the magnetic thin film is cut at the bonding part by differentiating the length of a nonmagnetic body of one opposing surface from that of the other nonmagnetic body between a couple of head pieces, forming a high-permeability magnetic thin film on the opposing surface of the longer head piece, and bonding both head pieces. CONSTITUTION:When high-permeability magnetic bodies 11a and 11b are nonmagnetic bodies 12a and 12b are bonded with an aq. org. adhesive such as polyimide and epoxy adhesive 13a and 13b to form a couple of head pieces 14a and 14b, the opposing surfaces 15a and 15b of the head pieces 14a and 14b are surface-ground and mirror-finished by polishing. A high-permeability thin film 16 is then formed on the surface 15a of one head piece 14a by vapor deposition, etc., and bonded with the org. adhesives 13a and 13b. A coil is wound around the magnetic bodies 11a and 11b to obtain a head. In this case, the length from the leading end of the nonmagnetic body 12a of the opposing surface 15a of one head piece 14a is made shorter than that of the other nonmagnetic body 12b. Consequently, a recess 19a is formed at the end part of the adhesive 13a on the polished opposing surface 15a of the head piece 14a, and the magnetic connection between the film 16 and the magnetic body 11b is maintained, even when the magnetic thin film 16 is cut. Consequently, the characteristic is not deteriorated.

Title: Prepayable rental locker apparatus
Inventor: OGAWA ATSUJI
IPC: G07F17/12
Filed: 1987-08-31
Abstract: PURPOSE: To make a user surely carry out the second locking of a coin locker after its use and to prevent the illegal use of the locker by making a coin holding rotary plate sink lower than a coin guide path by the second locking of the locker after its use and returning the remaining coins to the user. CONSTITUTION: The locker lock device is kept locked and never used unless a prescribed number of coins are thrown into the locker. Then, a strained lock means is released and the locker can be unlocked when those coins are thrown into the locker, and the door of the locker is opened and the baggage can be put into the locker. Thus, the door is closed and locked again. The coins are never partly returned to a user just by unlocking the locker and taking out the baggage. When the door is closed and the locker is locked again, a coin holding rotary plate 34 sinks lower than a coin guide path 3. As a result, the coins held by the plate 34 are returned and the door is never opened after the locker is locked again. Thus, the second locking of the locker is surely carried out by the partial return of coins, so that the locker can be prevented from being used illegally without paying charge.
