Patent JP-H07162076-A (JP)
Title: Semiconductor laser element
Inventor: SASAKI KAZUAKI
IPC: H01S5/00
Filed: 1993-12-03
Abstract: PURPOSE:To stably maintain maximum light output characteristics at a temperature higher than or equal to a specified temperature. CONSTITUTION:A window layer 11 is formed on the light radiation edge face side of a laser element main body. The window layer 11 has a multiple quantum barrier structure formed by alternately laminating two or more kinds of layers which are composed of one or more materials of GaInP and AlGaInP and are different in band gap. By forming the window layer 11 in this way, the potential barrier U between an active layer 4 and the window layer 11 is increased, so that electrons can be effectively confined. Hence high output characteristics can be maintained at a temperature higher than or equal to 70 deg.C.

Title: Gas-blast circuit breaker
Inventor: ENDO FUMIMASA
IPC: H01H33/70
Filed: 1991-11-20
Abstract: PURPOSE:To increase the inter-pole transition dielectric strength during contact- parting time period by making a second nozzle-axial length of the protrusion, provided to a flared portion of the nozzle, equal to or larger than a first inclined surface length. CONSTITUTION:When the breaker starts to be opened, the gas in a buffer chamber 4 in a cylinder 3 is compressed and starts flowing through the interior of a nozzle 5 with a high speed. The compressed gas passes through a throat 50 expands at a flared portion 51. Then, it impinges upon a first inclined surface 52a of a protrusion 52 and the direction of its flow is bent by means of a stator 1. Subsequently, it flows in the form of an axis-symmetry along a second inclined surface 52b of the protrusion 52 as indicated by the arrow A. Since the relation between the nozzle-axial lengths L1 and L2 of the inclined surface 52a, 52b is set as L2/L1>=1, the gas is effectively blown off to the stator 1 so that the gas pressure at a tip end of the high-field stator 1 is prevented from being lowered.

Filed: 1994-12-08
Abstract: PURPOSE: To use water only for circulating water by a method wherein a branch pipe having a solenoid valve, which is opened when the operation of a heat source device is stopped (power source is turned OFF), and a non-powered valve, which is opened when an ambient air temperature lowers down to a specific level or below, both the valves being provided in series with each other, is connected to a bypass pipe connecting a hot-water supply pipe to a hot-water return pipe. CONSTITUTION: A branch pipe 31 is provided to a bypass pipe 25 connecting a hot-water supply pipe 22 to a hot-water return pipe 23, and a solenoid valve 32, which is opened when operation of a heat source device is stopped (power source is turned OFF), and a non-powered valve 33 are provided in series with each other and connected to the branch pipe 31. The operation-free valve 33 is opened when an ambient air temperature lowers down to 3 deg.C or below and is closed when it rises up to 10 deg.C or above.  With this arrangement, even when the ambient air temperature lowers down to 3 deg.C or below during operation of the heat source device 1, circulating water is not discharged and, only when the ambient air temperature lowers down to 3 deg.C or below during the stopping of operation of the heat source device 1 (power source is turned OFF), the circulating water is discharged, thus preventing a heat exchanger 15 and the like from being broken by the freezing of water in the heat source device 1.

Title: Inverter lighting controller for fluorescent lamp
Inventor: MORITA TAKASHI
IPC: H05B41/24
Filed: 1988-12-01
Abstract: PURPOSE:To automatically cut off energization to a filament when a fluorescent lamp is not normally lit by separating a capacitor from a series resonance circuit when an energization time after the starting of energization reaches a preset time on the basis of information of a timer means. CONSTITUTION:Upon an ON operation of a power switch 1, a voltage applied to a fluorescent lamp 5 is gradually increased as a time elapses by the function of a time constant circuit 11 attached to a variable resistance circuit 10, and further, the voltage is under a preset value restricted by an output voltage control circuit 13 when a preset time passes after the starting of energization. Namely, the circuit 13 detects a resistivity divided voltage at an inductance L, a capacitor C and a contact point forming a series resonance circuit 7, and then, when the detected voltage exceeds the preset value, the capacitor C is separated from the circuit 7 via the contacts (a), (b) of a relay RL such that the voltage applied to the fluorescent lamp 5 can be eliminated at a low value.

Title: Temperature control method
Inventor: KITAMURA MASAMI
IPC: G01K11/12
Filed: 1990-11-09
Abstract: PURPOSE:To make the confirmation of a change after cooling and the repeated use in pressurizing treatment possible without generating toxity by partially applying pressurizing treatment to the synthetic resin surface of a base material at specific temp. from the glass transition temp. of the synthetic resin to the m.p. thereof to impart the optical strain of an uneven structure to the synthetic resin surface. CONSTITUTION:The optical mark strain 3 of an uneven structure is imparted to the smooth synthetic resin surface of a base material 1 by a stamp 4. The stamp 4 has an uneven surface 41 and a smooth surface 42 and is pressed to the surface 2 at specific temp. to impart the mark strain 3 to the surface. When the temp. is below the glass transition temp. of the synthetic resin, it is difficult to impart the mark strain and, when the temp. exceeds the m.p. of the synthetic resin, the resin is permanently deformed, not restorable to the original shape and, therefore, the temp. is set to the range from the glass transition temp. of the synthetic resin to the m.p. thereof. This mark strain 3 generates the difference in the reflectivity of light and can be confirmed by an optical means or can be directly confirmed visually. The strain is released to disapper when the synthetic resin becomes a temp. equal to or higher than strain imparting temp. and it is confirmed that the synthetic resin reaches the specific temp.
