Abstract: PURPOSE:To enable a light detecting section to be readily utilized for, for example, control of the intensity of light emitted from the laser body of a plane light emission type semiconductor laser, by forming a light detecting section integral with the periphery of the laser so that the light detecting section detects light generated in a direction perpendicular to the laser light. CONSTITUTION:A light detecting section is formed integral with the periphery of a plane light emission type semiconductor laser to detect light generated in a direction perpendicular to the laser light. For example, an inverted truncate cone-shaped bore 1a is formed in the center of an N-type DaSa substrate 1, and an N-GaAlAs clad layer 2, a P-GaAlAs active layer 3 and a P-GaAlAs clad layer 4 are stacked on one surface of the substrate 1. A common electrode 5 is formed on the other surface of the substrate 1, while an electrode 6 also serving as a mirror is formed on the center of one surface of the clad layer 4, and a ring-shaped electrode 7 is formed along the peripheral edge of this surface of the clad layer 4. A ring- shaped groove 8 having a trapezoidal cross-section is formed at a position intermediate between the electrodes 6 and 7 so that the groove 8 divides the stack of the clad layer 4 and the active layer 3 into the central portion and the peripheral edge portion and the bottom of the groove 8 reaches the clad layer 2. Thus, a plane light emission type laser body 9 is formed on the central portion, and a photodiode 10 serving as a light detecting section for the laser body 9 is formed on the peripheral edge portion.

Title: Image forming device
Inventor: ENDO YOSHINORI
IPC: G03B27/72
Filed: 1991-06-26
Abstract: PURPOSE:To shorten time required for forming an image and further to always form the high-quality image. CONSTITUTION:The brightness of a light beam emitted from a halogen lamp 3 is detected by a brightness sensor 14. Then, the clock pulse of frequency in accordance with output from the sensor 14 is outputted by a V/f converter which constitutes an exposing time control circuit 73 and counted by a counter. When the specified number of pulse is counted, an exposure finishing signal is transmitted to a CPU 65. At this time, the larger the output from the sensor 14 is, the higher frequency of clock pulse is outputted by the V/f converter, so that the higher the brightness of the lamp 3 is, the shorter the time until the exposure finishes. Therefore, even when the brightness of the lamp 3 is changed, the quantity of light with which a microcapsule paper 17 is irradiated becomes constant.

Inventor: OGAWA KAZUO
IPC: H04L5/14
Filed: 1978-12-14
Abstract: PURPOSE:To omit the reception local oscillator by utilizing part of the transmission modulation signal for the reception local oscillation output. CONSTITUTION:The transmission digital signal is modulated directly by FM modulator 22 and then fed to antenna 25 via circulator 24. The reception modulation signal received at antenna 25 is then transmitted to port (3) from (2) of circulator 24. At the same time, part of the transmission power corresponding to the backward attenuation amount which is transmitted from port (1) to (3) is applied to frequency converter 27 along with the reception modulation signal. The 1st intermediate frequency signal delivered from converter 27 contains the transmission modulation signal component but is mixed with the output of voltage control oscillator 33 to be negated. The output of the frequency converter with the transmission signal component negated contains only the reception modulation signal component to be delivered from frequency discriminator 32. In such way, the reception local oscillator can be omitted.

Title: Light condensing and dispersing thin film
Inventor: KATSURAGAWA TADAO
IPC: G02B3/00
Filed: 1991-05-31
Abstract: PURPOSE:To provide a lightweight/small/transparent thin film having a lens function capable of condensing/dispersing light by increasing refractive index to the light as its position moves outside from the center of the film. CONSTITUTION:Average particulate diameter of ultrafine particulates dispersed in a film is set to become large as its position moves outside from the center of the film. Furthermore, the average particulate diameter of the ultrafine particulates is controlled so that refractive index to light become large as the position moves outside from the center of the film. In order to change the average particulate diameter of the ultrafine particulates in an ultrafine particulate dispersing thin film consecutively in the same film, a simple method is to give gradient to substrate temperature. Since the average particulate diameter of the ultrafine particulates in the film differs according to the substrate temperature, the average diameter becomes large as its temperature becomes high. Accordingly, it is preferable to give the gradient to the substrate temperature in the case of forming the film.
