Title: Optical switch
Inventor: SHIRASAKI MASATAKA
IPC: H04B10/135
Filed: 1980-08-30
Abstract: PURPOSE:To put a low-magnetic-field drive type optical switch to practical use, by correcting a phase shift between a P-polarized component and an S-polarized component by adhering a phase matching film of multilayered structure to both the opposed sides of a thin magnetooptical crystal plate. CONSTITUTION:To both the opposed surfaces of a thin magnetooptical crystal plate 1 having greater length in an optical waveguide direction than thickness, a phase matching film consisting of thin films 7 and 8 which differ in refractivity and have prescribed thickness is adhered. Consequently, light incident from the flank 1a of the thin plate 1 travels while reflected repeatedly by both the surfaces where the phase matching film is adhered, correcting a shift in phase between the P- polarized component and S-polarized component of the incident light in the thin plate 1. Then, an electromagnet 2 is used to apply magnetic field in the optical waveguide direction and in the opposite direction to the inside of the thin plate 1, thereby switching planes of polarization. Thus, an electromagnet device used for the switching of the planes of polarization is miniaturized and an optical switch utilizing magnetooptical crystal driven with a low magnetic field is put to practical use.

IPC: G03G15/04
Filed: 1977-10-07
Abstract: PURPOSE:To perform temperature control for the LD element, by utilizing the forward voltage of LD element related to the junction temperature of LD element. CONSTITUTION:When the switch. conduct 31 is closed, the LG element 26 is sufficiently contacted and oscillated, and when the contact 30 is closed, the power application is insufficienct for the oscillation due to the resistor 28. With the terminal voltage of element by the circuit 32, the junction temperature and the standard operating temperature are compared and the control signal is fed to the temperature control circuit 33. The circuit 33, in case of cooling, feeds power to the peltier element via the terminal plates 21 and 23. Thus, LD is cooled by Peltier effect. When heating LD, the direction of power application of the element 22 is inversed. Thus, the junction temperature of LD element actually can quickly be detected and the temperature control of LD can be made.

Title: Thermal battery
Inventor: TOMITA MASAO
IPC: H01M6/36
Filed: 1993-04-23
Abstract: PURPOSE:To obtain a thermal battery whose discharge voltage does not become unstable. CONSTITUTION:Plural unit cells 1 which consist of a positive electrode plate 3, a negative electrode plate 5, and an electrolyte 4 respectively are laminated through heating bodies 2, and at the same time, the bare batteries are connected each other by collectors 6 placed between the unit cells and the heating bodies 2, so as to form a thermal battery. The diameter of the collector 6a at the side connecting to the positive electrode plate 3 is made smaller than the diameter of the collector 6b at the side connecting to the negative electrode plate 5. As a result, even though the negative electrode plate is fused and moved from the periphery to the positive electrode plate side, it does not generate a short circuit by making contact with the collector contacting to the positive electrode plate, and an unstable condition of the discharge voltage can be prevented.

Title: Semiconductor laser
Inventor: ABE YUJI
IPC: H01S5/12
Filed: 1985-06-04
Abstract: PURPOSE:To obtain a semiconductor laser that is easily integrated and oscillates in single longitudinal mode at the time of high-speed modulation with its oscillation wavelength less dependable on temperature, by providing a diffraction grating for distributed feedback vertical to the substrate. CONSTITUTION:A diffraction grating for distributed feedback 11 is provided near an oscillative region 10 so as to act in the direction vertical to a substrate 7 and parallel to the interface of a P+ diffusion region. In this semiconductor laser, light is produced in the oscillative region 10 when forward direction bias is applied between a p-electrode 1 and an n-electrode 8, however, only the light, which meets the Bragg's reflective condition which is determined by the cycle of the diffraction grating for distributed feedback, is amplified and oscillated since the light is weakly confined in transverse direction with larger leaking effect of light. Thus, the dependancy of the oscillation wavelength is made smaller, facilitating the operation in the single longitudinal mode at the time of the high-speed modulation. Moreover, this device does not require a cleavage plane as a resonator, making it possible to be integrated with other photo-elements.
