IPC: H01S5/24
Filed: 1982-10-14
Abstract: PURPOSE:To manufacture the titled laser device with a crescent-shaped active layer formed on a grooved substrate by a method wherein various layers including an active layer are formed on a substrate with a devetail groove the depth of which fluctuates discontinuously while the lower surface of the active layer above the groove is formed into a convex crescent-shape. CONSTITUTION:A first N type clad layer 2, a second active layer 3, a third P type clad layer 4 and a fourth current limiting layer 5 are continuously grown on an N type substrate 1. A dovetail groove is formed on the substrate 1 either by an etching before the growth or by utlizing both the etching before the growth and the melt-back in case of the growth. The active layer 3 thus formed on the groove is formed into crescent-shape by means of adjusting the growing time of the first clad layer 2. After growing the fourth current limiting layer 5, a P type impurity is selectively diffused into stripe type to make the diffused front reach the third clad layer 4. After removing a diffusion preventing film 17 grown on the crystal surface for the selective diffusion, a P side ohmic electrode 6 may be formed while N side ohmic electrode 7 may be formed likewise on the substrate side.

Filed: 1989-07-12
Abstract: PURPOSE:To receive an NRZ data while a bit error rate and a pulse width distortion are minimized by controlling a threshold voltage of an optical reception circuit when an initializing signal whose mark rate is 1/2 is received and keeping the set threshold voltage when a signal other than the initializing signal is received. CONSTITUTION:The system consists of an optical transmission circuit 1 receiving a binary NRZ signal from an NRZ(non return zero) data input terminal 8 and receiving a switching signal from a switching signal input terminal 7, an optical reception circuit 3 connecting to an output of the optical transmission circuit 1 and an NRZ data output terminal 14 connecting to the output of the optical reception circuit 3. Then the binary NRZ data and an initializing signal whose mark rate is 1/2 are selected and sent and when the initializing signal is received, the threshold voltage is adjusted so as to minimize the bit error rate and the pulse width distortion corresponding to the reception signal level. When a signal other than the initializing signal is received, the set threshold voltage is kept even when the signal is changed. Thus, the dispersion in the transmission loss is large and the NRZ data including the DC component is received while the bit error rate and the pulse width distortion are minimized.

Title: Control method for heat storage type air conditioning system
Inventor: KAKUNO OSAMU
IPC: F24F11/02
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To simplify a measuring system by controlling a thermal storage and heat radiating operation based on the relation between primary medium temperature and thermal storage level and the measured temperature of the primary, medium when a heat exchanging is carried out between a primary medium system for circulating the primary medium between a heat storage tank and a refrigerating machine, and a secondary medium system for circulating a medium to a secondary medium air conditioning space. SOLUTION: Primary medium of -5 deg.C is supplied to ice thermal storage tanks 2 from a refrigerating machine 3 during heat storage operation. The primary medium is subjected to a heat exchange therein and discharged at a temperature of -2 deg.C. Thus, ice between pipelines comes into contact with the primary medium, so that the cooling areas of the pipelines are decreased and the outlet temperature of the ice thermal storage tank is lowered. During a heat radiating operation, the ice between the pipelines becomes water so that the outlet temperature of the ice thermal storage tank rises. Thus, thresholds are respectively determined by a heat storage completion temperature setting device 34 during the heat storage operation, and by a heat radiating completion temperature setting device 35 during the heat radiating operation based on the outlet temperature of the ice thermal storage tank of the primary medium when heat storage level reaches a prescribed value. Then, a storage detecting part 33 outputs a heat storage completion signal and a heat radiation completing signal based on an input signal from a temperature converter 32 and the thresholds by the temperature setting devices 34 and 35.

Title: Distortion correcting device of inkjet printer
Inventor: OMORI HIDEYUKI
IPC: B41J2/13
Filed: 1988-07-22
Abstract: PURPOSE:To secure a high printing quality by reading the result of printing by an image recording unit, determining how much each printing dot deviates from a reference, and correcting the size of a charging signal so that said deviation be minimum. CONSTITUTION:An objective dot to be corrected is hatched, which deviates downward from a reference lattice position. In order to raise the dot, if a particle is present at a position (b), the size of a charging signal to be applied to the objective dot is corrected to be increased. The voltage of the objective dot is Vs7 from a reference step waveform in the drawing. Supposing that the voltage to the dot when the charging signal is corrected by a constant (b) is Vs7R, an equation Vs7R=Vs7+Vs6X(b) holds. Vs6 is a voltage at the sixth step from below when no correction is required. The constant (b) is a correcting coefficient value not larger than 1. Some value is set as an initial value for the constant (b) which is sequentially changed larger. Thus, an optimum value of the constant (b) is obtained. When the correcting coefficient of (b) is determined, values of (c), (a) and (d) are sequentially determined. Finally, the distortion rate of the whole character is measured to judge whether or not the distortion rate is within a permissible range.
