Title: Piezoelectric actuator-driving circuit for selecting needle of knitting machine
Inventor: TAKAHASHI MINORU
IPC: D04B15/82
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a highly efficient piezoelectric actuator-driving circuit for selecting the needles of a knitting machine, capable of reducing the loss of an electric current due to electric current-limiting resistance and the loss of switch elements as much as possible. SOLUTION: In this piezoelectric actuator-driving circuit for selecting the needles of a knitting machine, a curving movement is generated by using a laminate type piezoelectric member having a three terminal structure and applying a driving signal between a grounding electrode G and one of the first and second driving electrodes A, B. Therein, series circuits (Q1+LA and Q3+LB) for switch elements (for example, transistors) and induction elements (for example, coils) are connected between the first and second driving electrodes A, B and an electric source +VCC, and a switch element-driving control means (for example, a transistor driving-control circuit 90) for on-off control in a sufficient short time based on the time for driving the piezoelectric actuator is disposed.

IPC: F04B39/04
Filed: 1983-12-28
Abstract: PURPOSE:To prevent a compressor from breakdown, by exhausting a laid-up liquid refrigerant being separated into two layers inside a hermetically sealed vessel, from the inside of the vessel. CONSTITUTION:A liquid exhaust valve 29 being opened or closed by means of liquid weight is installed in the bottom of a hermetically sealed vessel of an enclosed compressor 1, and connected to an external regenerator 15 through pipes 30 and 32 via solenoid on-off valve 31, then a position of a connecting part 5c of the pipe 32 is set down to height H commensurate to the amount of a liquid refrigerant to be exhausted. After operation stoppage, when the refrigerant dissolves in lubricating oil inside the hermetically sealed vessel and thereby its weight goes beyond the specified value, the liquid exhaust valve 29 opens, as well as when a fact that temperature comes down to the extent of below that makes it separate into two layers is detected by a feeler part 33, the solenoid on-off valve 31 gets opened, exhausting the liquid refrigerant inside the vessel, thus it housed inside a regenerator 5.

Abstract: PROBLEM TO BE SOLVED: To enable the reduction of the quantity of the residue of combustible waste by collecting iron component in residue after incineration, mixing the residue with unburned combustible waste and re-combusting it by a rotary kiln. SOLUTION: Hard to combust combustible is incinerated by a batch incinerator 1 of a gas incinerator or a simple incinerator with a fixed hearth, residue a discharged from the lower part of a furnace and stored in a residue pit 2 is carried to a magnetic separator 4 and the residue is separated into magnetic residue b and non-magnetic residue c being collected into a collecting pits 5 and 6. The non-magnetic residue c is mixed with unburned combustible waste 7, the mixture d is input into a rotary kiln 9 by a lifter 8 and incinerated. The rate of mixture between non-magnetic residue c and unburned combustible waste 7 is 20 to 80%, of non-magnetic residue c against the total incinerating quantity of 100%.  If the ratio exceeds this range, the rate of generated residue is increased and on the other hand, when the residue quantity in a batch incinerator is less, the rate of residue decreases but it becomes almost constant at 20% or less.

Title: Method for treating steelmaking slag producing at steelmaking process
Inventor: KAWAKAMI MITSUHIRO
IPC: C21C7/00
Filed: 1988-10-05
Abstract: PURPOSE:To reduce unit consumption of a flux needing to refining by adding the prescribed quantity of flux into molten steel tapped into a ladle to execute prevention of re-phosphorization and heat holding of the molten steel and directly re-charging the ladle slag into a refining furnace after discharging the molten steel. CONSTITUTION:At the time of tapping the molten steel into the ladle from the refining furnace, the flux of lime, etc., is added at 1-10kg/t of molten steel to the molten steel in the ladle. By this method, the re-phosphorization and molten metal temp. drop are prevented. Successively, the molten steel is discharged into a casting machine from the ladle, and the remained ladle slag is directly re-charged into the refining furnace. Before re-charging this, it is desirable to avoid heat loss by bringing this ladle slag into contact with cooling material of scrap, etc., as chargable into the refining furnace and cooling. By re-charging the above ladle slag into the refining furnace, the unit consumption of the flux in the refining furnace is reduced and also by recovering the metal content in the ladle slag, the steelmaking cost can be reduced.

Title: Photodetecting ic
Inventor: WADA YOSHIYUKI
IPC: H01L31/10
Filed: 1989-09-26
Abstract: PURPOSE:To prevent a switching speed from being deteriorated by a parasitic capacity by a method wherein an emitter region is formed in a base region of a photodiode which is formed of the base region and an epi region in a photodetecting part and its potential is set to an epi potential. CONSTITUTION:A capacity which is formed of a base region 1.7, SiO2 1.4 and a polysilicon layer 1.6 becomes a parasitic capacity 5.1 as shown in the figure. Consequently, an emitter region 1.8 is formed in the base region 1.7 and a potential is connected to the potential of an epi. Thereby, the parasitic capacity 5.1 is inserted between a cathode and a ground, and the parasitic capacity is not formed between the input of an amplifier and the ground. As a result, it is possible to prevent a switching speed from being deteriorated by an effect of the parasitic capacity between these. When the potential is set to the potential of the epi region, it is not connected by a one-layer aluminum interconnection, but the emitter region is formed up to a contact formation region of the base region and the epi region by a diffusion operation. Thereby, it is not required to form a contact formation part in the emitter region.

Title: Manufacture of semiconductor device
Inventor: OKADA TAKASHI
IPC: H01L21/336
Filed: 1991-09-30
Abstract: PURPOSE:To enable a gate electrode side to be used as a mask for forming an N<+> high concentration diffusion region without forming a thin film which serves usually as a side wall material into a side wall. CONSTITUTION:An insulator or a semiconductor thin film 7 is formed on all the surface of a semiconductor substrate 1 where an N<-> low concentration diffusion region 4 has been formed, and an ion implantation operation is carried out in such a manner that ions are accelerated to reach to a certain energy level to penetrate only through a part other than parts 7s located at both the sides of a gate electrode 5 on the thin film 7, whereby N<+> high concentration source/drain regions 9 are formed. Therefore, even if the thin film 7 is not provided as a side wall, only the parts 7s (usually formed as side walls) of the thin film 7 located at the gate electrode sides function as an ion implantation mask, so that 8 process where the thin film 7 is anisotropically etched can be dispensed with, and in result the substrate can be protected against damage caused by the anisotropic etching operation concerned.
