Title: Drive controller for parts feeder of vibratory bowl type
Inventor: YAKUSHIJI NOBUO
IPC: B65G27/32
Filed: 1982-05-07
Abstract: PURPOSE:To diminish consumed electric power and improve efficiency, by comparing a parts supply member vibration drive signal with a parts supply member resonance frequency signal and controlling a driving oscillator to equalize the frequency of the drive signal to the resonance frequency. CONSTITUTION:The output signal of an oscillation circuit 16 is amplified to excite an electromagnet 1 to move a bowl 5 up and down at resonance frequency. The vertical movement of the bowl 5 is applied through the bent part 9 of a shutter 8 so that a sinusoidal signal corresponding to the resonance frequency is generated through a light emitting diode 10 and a phototransistor 11. The output of the phototransistor 11 is applied to a phase detection circuit 17 through a capacitor 13 and an amplifier circuit 14 so that the phase difference between the outputs of the oscillation circuit 16 and the phototransistor is detected and applied to a control circuit 18. The control circuit 18 regulates the oscillation circuit 16 to make the phase difference zero. According to this constitution, commercial AC power can be used under simple adjustment and the efficiency of vibration is improved.

Title: Titanium clad steel sheet having austenitic stainless steel excellent in corrosion resistance as base material and production thereof
Inventor: YAMAMOTO AKIO
IPC: C22C38/00
Filed: 1990-03-28
Abstract: PURPOSE:To enhance corrosion resistance of a cutting face and a rear by utilizing austenitic stainless steel wherein the components of C, Si, Mn, Cr, Ni and N are specified. CONSTITUTION:Titanium or titanium alloy is produced by utilizing austenitic stainless steel which contains <=0.03% C, <=1.0% Si, <=2.0% Mn, 15-27% Cr, 6-22% Ni, <=0.03% N and consists of the balance Fe and inevitable impurities as the base material and constituting the clad material. Si and Mn are regulated to 1.0% and 2.0% respectively as the upper limit because hot workability is deteriorated when these are added at large amounts. Cr is regulated to 15% as the lower limit from a point for securing corrosion resistance of the base material. Corrosion resistance of this base material is enhanced as the amount of Cr is made more plenty. However, Cr is regulated to 27% as the upper limit because toughness is deteriorated and moreover rise of cost is made large. Ni is regulated to 6% as the lower limit to secure the structure in austenite of stainless steel of the base material. N is regulated to 0.03% as the upper limit because nitride of Cr is deposited after hot rolling and corrosion resistance is deteriorated when N exceeds 0.03%. When <=4% Mo and <=1.5% Cu are added independently or compositely to stainless steel of the base material, enhancement of corrosion resistance is more obtained. Further when <=0.5% Ti and <=1.0% are added singly or compositely, corrosion resistance is further improved.

Title: Semiconductor device
Inventor: HIRASAWA SHIGEKI
IPC: H01L21/20
Filed: 1990-03-28
Abstract: PURPOSE:To selectively heat-treat a microscopic element formation region even when the whole face of a semiconductor substrate is irradiated uniformly with a laser beam by a method wherein the thickness of an insulating film formed between a semiconductor thin film and the substrate is formed in such a way that only the formation part of an electronic element is thick. CONSTITUTION:At a semiconductor device where an electrically insulating film 3 is formed on the surface of a semiconductor substrate 1, a semiconductor thin film 2 is formed on its upper layer and an electronic element such as a transistor or the like is formed at the inside of the semiconductor thin film 2, the thickness of the insulating film 3 is formed in such a way that only the formation part of the electronic element is thick. For example, an insulating film 3a at the lower part of a part (e.g. a transistor formation part) 2a requring a heat treatment is made thick in a silicon thin film 2. Thereby, when a laser beam is irradiated from the direction of arrows 5, the temperature of the silicon thin film 2 on the surface of a semiconductor device is raised. At this time, heat at the region 2a of the silicon thin film at the upper part of the part 3a in which an insulating film is thick is insulated by the insulating film. As a result, the energy of most of the irradiated laser beam is absorbed, and a temperature is raised by that amount.

Title: Semiconductor device
IPC: H04L12/40
Filed: 1992-03-31
Abstract: PURPOSE:To prevent the destruction and degradation of elements in a circuit in which a high voltage source potential level is driven by low voltage source potential by connecting bus lines for high voltage source potential and low voltage source potential to be connected with output drivers for high voltage source potential and low voltage source potential by transistors. CONSTITUTION:The logical level of a bus line for high voltage source potential 70 is determined by drivers for power source potential 50, 60. When the bus line 70 reaches high voltage source potential VDD or a H level, the level which drops by the threshold potential of a transistor(Tr) NMOS 91 having a connection means 90 is obtained in a bus line 80 for low voltage source potential. The Tr NMOS 91 is possible to optimize the threshold potential as it is composed of elements other than those of the output drivers 50, 60. Therefore, the bus line 80 is not impressed by the high voltage source potential VDD and the output level of the driver 50 is expressed as the H and L levels of low voltage source potential VCC on the bus line 80. Thus, the degradation and destruction of the elements in the circuit where the drivers 60 driven by low voltage source potential are possible to be prevented.

Abstract: PURPOSE: To improve detection precision by placing a loop circuit across the secondary winding of an oscillation transformer in a state close to resonance by providing a feedback phase and amplitude adjusting circuit between one terminal of the primary winding and the collector of a transistor.  
     CONSTITUTION: At the stage of adjustment, the loop circuit consisting of secondary winding L 2  of oscillation transformer T, and capacitors C 1  and C 2  is placed in a state close to resonance and feedback phase and amplitude adjusting circuit N 1  is used to adjust properly feedback to the oscillating circuit consisting of transistor Q 1 , transformer T, etc., so that oscillation of amplitude h 1  will be caused between collector B of Q 1  and earth terminal E at time (t). As a person approaches a parallel plate detector, the oscillation amplitude decreases without reference to whether the capacity of the detector changes much or a little and the phase shifts through circuit N 1 . This change is amplified by transistor QL connected via detecting/amplifying circuit N 2  and output from self-compensating circuit N 3 . Consequently, the detection precision can be improved while malfunction is eliminated.

Abstract: PURPOSE: To obtain a constant voltage circuit which is capable of free setting of the output voltage by installing the level shift circuit and the reference voltage generation circuit constituted by short-circuiting the source and the gate of depression MOSFET(DMOST).  
     CONSTITUTION: Reference voltage generation circuit 4 gives a short circuit to the gate and source of DMOST2 to produce the constant current, and then supplies the constant current to MOS load 3 to deliver potential V 1  at connection point P 1  of MOS2 and 3. When the potential of output terminal 9 at the connection point of constant current MOS5 and load MOS6 is changed from 0 to power voltage VSS, the current flowing through MOS5 and that flowing through MOS load 6 become as shown by curve c and d respectively. And potential V 2  at intersection Q 2  of curves c and d becomes the output voltage of terminal 9 in level shift circuit 7. The output voltage V 2  sufficiently higher than output voltage V 1  of circuit 4 is delivered from circuit 7, and at the same time current I 2  flowing through MOS5 is sufficiently more in amount than current I 1  flowing to MOS2. As a result, a sufficient amount of power can be supplied to the load. In the same way, voltage V 3  corresponding to intersection Q 3  between curves c and e can be obtained from output terminal 8.
