Title: An optical beam splitter
IPC: G02B27/10
Filed: 1988-11-21
Abstract: An optical beam splitter including a prescribed 
number of stacked transparent parallel plates (Pi) whose thicknesses 
are uniform to a high degree of precision, the back surface of 
the transparent parallel plate which is the farthest from the 
side at which light beam that is to be split enters is coated 
with a totally reflective film (Mo), while the back surfaces of all of 
the remaining transparent parallel plates are coated with 
different semi-reflective films (Mi) whose respective reflectivities 
gradually increase and the coating region of the totally 
reflective film and semi-reflective films are positioned in an 
oblique arrangement which is struck by the light beam traveling 
obliquely through the interiors of the transparent parallel 
plates. With this optical beam splitter, the incident light beam (Lo) 
is converted into a number of split light beams (Li) which are of 
equal luminous intensity by partial reflection by the respective 
semi-reflective films and total reflection by the totally 
reflective film, and the respective split light beams are emitted 
parallel to each other in a tow in the direction of the side of 
the stack from which the incident light beam initially entered 
without any of the split light beams striking the preceding semi-­
reflective films.

Title: Duty ratio control circuit apparatus
IPC: H03K5/04
Filed: 1989-12-28
Abstract: An integrating circuit (1) integrates an input 
signal. When an output from the integrating circuit (1) 
is input to an AC coupling circuit (2), only an AC com­
ponent of the output is extracted. The AC component 
which passes through the AC coupling circuit (2) is 
waveshaped and coverted into a rectangular wave by a 
waveshaping circuit (3). The duty ratio of the 
waveshaped rectangular wave is detected by a duty ratio 
detecting circuit (4). A voltage corresponding to the 
duty ratio is then generated and fed back to the output 
of the AC coupling circuit (2) through a feedback cir­
cuit (5). As a result, a DC bias component is applied 
to the AC component which has passed through the AC 
coupling circuit (2). In this case, the voltage 
generated by the duty ratio detecting circuit (4) is 
controlled to coincide with the circuit threshold value 
of the waveshaping circuit (3), and a rectangular wave 
having a duty ratio of 50% is output from the waveshap­
ing circuit (3).

gives such a high thermal energy to the recording mate­
rial at least at its central area of a beam spot formed 
on the recording material as to be able to convert the 
metastable phase into the stable phase under the condi­
tion that the central area of one beam spot is formed on 
the recording material in an area overlaping with an area 
of a central high thermal energy area of a laser beam 
spot having been formed by the preceding irradiation to 
convert a metastable phase into a stable phase and then 
recording another information in the recording material 
by irradiating the recording material with a laser beam 
to form a plurality of separated metastable-phase areas. 
Another method comprises a single process for erasing a 
recorded information, at a desired moment in the course 
of which a fresh information is recorded by prolonging 
interval between two laser beam irradiations.
