Title: Manufacture of semiconductor device
Inventor: TAMAOKI NORIHIKO
IPC: H01L21/762
Filed: 1986-02-18
Abstract: PURPOSE:To form a high density, high speed and low power consumption semiconductor device having small mutual action between elements, in which its parasitic capacity is reduced by forming a mask for an ion implantation on a portion to become the transistor region of the surface of a semiconductor substrate, implanting oxygen or nitrogen ions, and heat treating it. CONSTITUTION:Since the lateral spread of oxygen ions is necessary in a later heat treatment, an oxygen ion-rich implanted layer 4 is formed by increasing the implanting amount in an SIMOX method. The upper surface of the layer 4 is anisotropically etched to separate between elements to form a hole 5. A silicon oxide film (II) 6 and a silicon nitride film (II) 7 are so formed on the entire semiconductor substrate as not to allow the excessively implanted ions in the heat treating step from escaping at heat treating time. Then, a heat treatment of 1,100 deg.C or higher is performed to form a buried insulating layer 8 of a silicon oxide film on a region in which oxygen ions are diffused from the oxygen ion-rich implanted layer. A separation between elements is completed by the parts of the films 6 and 7 by flattening.

Abstract: PROBLEM TO BE SOLVED: To suppress the interface state density in a laser edge face by a method wherein elements constituting a plurality of passivation layers of a semiconductor light-emitting element are selected according to specified conditions. SOLUTION: As materials which are inserted in the interface between a laser edge face and a dielectric material as a passivation layer 14, specially passivation layers 14-1, when a diffusion of elements is caused during a long-period drive of a laser, specially during the high-output operation of the laser, the elements, which are introduced in an active layer 4 or the like as N-type impurities and cause an effective reduction in a hole concentration due to a compensation effect, are desirable. That is, Si and the like, which augment a band gap, wherein parts of the elements in the layer 14 are diffused with a drive of an LD, in the vicinity of the semiconductor laser edge face and make absorption of light in the laser edge face inhibit, are desirable.  On the other hand, as the elements which are adhered to the layers 14-1 or second passivation layers 14-2, elements having the absolute value of an oxide production enthalpy higher than that of the elements constituting the layers 14-1, Sc and the like are used. Thereby, the interface state density in the laser edge face can be stably suppressed extending over a long period.

Title: Automatic interference remover
Inventor: KANEKO ICHIRO
IPC: H03H15/00
Filed: 1991-02-05
Abstract: PURPOSE:To obtain good convergence of an automatic interference remover without sacrificing analog signal interference compensation characteristic to the convergence. CONSTITUTION:When the interference by an analog signal becomes large and as a consequence a carrier wave at the receiving side cannot be synchronous with a carrier wave at the sending side, a carrier wave synchronism detecting circuit 105', with the aid of a carrier wave asynchronous signal (CSL), outputs carrier wave asynchronous information. A reset circuit 38, when carrier wave asynchronous information is inputted, outputs a 3-tap control signal having a number of taps less than the normal number of taps as a control signal for an automatic interference removal circuit l04'. When the analog interference is reduced, and a consequence the receiving carrier wave synchronizes with the sending carrier wave, the carrier wave synchronism detecting circuit l05', with the aid of carrier wave asynchronous signal, outputs carrier wave synchronous information to the reset circuit 38, thereby the automatic interference removal circuit 104' acts as a 7-tap automatic interference removal circuit. Thus, the automatic interference remover can compensate for much greater analog interference. with the automatic interference remover made to hold the convergence equivalent to that of the conventional automatic interference remover.

Title: Superheated steam cooker
Inventor: HARA YUMIKO
IPC: H05B6/10
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To conduct highly efficient heating and manage not to damage a soft feel to eating by performing cooking with superheated steam having good heating efficiency. SOLUTION: A superheated steam generating means 6 generates superheated steam in accordance with the outputs from a cooking control means 7 and a plane heater 3 heats a heating box walls in accordance with the outputs from the cooking control means 7. When the generated steam temperature is high, electric energy is increased by an electric control means and the flow rate of water is reduced, and therefore water is heated more rapidly and the steam is heated to have much higher temperature. When the superheated steam collides with low temperature objects and alters to water, latent heat is given to the objects to transfer temperature thereto. The heating box 1 is heated in order to prevent the superheated steam from altering to water when collided with the heating box walls. The heating box walls are heated by the plane heater 3 to not less than 100 deg.C to efficiently heat food.  Superheated steam of less than 120 deg.C is appropriate for steam cooking and that of not less than 120 deg.C is appropriate for roast cooking.
