Title: Manufacture of semiconductor laser
Inventor: KIMURA HIDE
IPC: H01S5/00
Filed: 1990-10-23
Abstract: PURPOSE:To maintain a film thickness required for obtaining self-excited oscillation under a well controllable condition by maintaining the film thickness by forming a specific etching stop signal layer and performing prescribed additional etching after confirming that the signal layer is removed by etching. CONSTITUTION:An etching stop signal layer 11 is set to a film thickness of d1+0.3mum so as to secure a distance d11 against an active layer 2. Then, after the layer is removed by etching, a desired film thickness d1 is obtained by performing additional etching for an etchant of 0.3mum at an etching rate (mum/sec). Therefore, the clad thickness of a semiconductor laser having no etching stop signal layer in the light emitting region can be secured under a well controllable condition.

Title: Automatic rice cooker
Inventor: HARADA NOBUYA
IPC: A47J27/00
Filed: 1990-10-23
Abstract: PURPOSE:To enable a proper rice washing with a proper amount of water by controlling rice washing with a prescribed supply volume. CONSTITUTION:Rice washing data selected by a washing selecting button is called out and set. For example, it is preliminarily determined that, if rice cooking volume is 1 sho (1.8l) and washing is soft, water supply volume is 10l and washing time is 67 seconds, and this data of 10l and 67 seconds is set. A shower solenoid valve becomes ON and water scattering from a shower water supply pipe into a rice washing tank 16 starts, a rice washing motor turns ON to start rotation of a stirring means. At this time, the water supply volume is counted by a flow rate sensor 24, and when the water supply volume reaches the set 10l, the shower solenoid valve 25 turns OFF. On the other hand, as the water supply volume is set to an appropriate value in a water volume confirming process, if it is controlled by time, the water supply volume does not displace from its appropriate value to a great extent.

Title: Cooking utensil
Inventor: KISHIMOTO SHUZO
IPC: F24C7/04
Filed: 1990-10-24
Abstract: PURPOSE:To prevent the practice of poor-finished heating in advance by announcing an error when the temperature of a heating chamber drops considerably due to the door opening and fails to exceed a certain temperature (lower than required temperature for preheating). CONSTITUTION:When a door 3 is opened so as to house food in a heating chamber 2, a control section 7 shuts off power supply to a heater 6. When restart is indicated with a keyboard 4, the control section 7 performs affirmative consideration and a thermistor 9 inputs the in-chamber temperature detected. Then, the control section 7 compares the input detected temperature with a specific temperature which is lower than a required preheating temperature by k deg.C. When the opening time of the door 3 is long and hence the heated chamber especially preheated is cooled to a considerable extent, the detected temperature is lower than the specific temperature with regards to the above comparison. In this case, the control section 7 does not carry out heating operation and drives an error annunciator 10 for error warning. This construction makes it possible to prevent the operation of undesirable food heating under insufficient preheating conditions.
