Title: Fm-cw radar device
Inventor: ISAJI OSAMU
IPC: G01S13/34
Filed: 1990-11-14
Abstract: PURPOSE:To reduce influence of FM-AM noise inherent to an FM-CW radar and enhance the sensing ability for a near target by furnishing a circuit to shift slightly the frequency of either of the local signal, transmitted wave, and a reflex wave received. CONSTITUTION:A mixer MIX2 shifts Fo by f1 with the output of an oscillator PLO1. The f1 is related to Fo as Fo>>f1, for example being 1GHz. As a result of this frequency shift, Fo-f1, Fo+f1, Fo, and f1 are generated in the output of the mixer MIX2. From these, Fo-f1 is extracted by a filter BPF1. By another mixer MIX3, Fo-f1 is further shifted by f1+f2 with the output of an oscillator PLO2 (f1>f2). If Fo+f2 is made double by a doubler circuit MUL2 as final stage, a local signal Lo of 2F0+2f2 is obtained. When now R and LO are entered and the output of a mixer MIX1 is passed through a filter BPF3 of characteristics, a signal component having got rid of FM-AM conversion noise can be extracted.

Abstract: PROBLEM TO BE SOLVED: To integrate a functional member easily with excellent watertightness by a method wherein the functional member is joined to a protective plate of a synthetic resin material and molded in one of paired mold tools and at least the peripheral part of the protective plate is fusion-bonded onto the surface of a seat or a back-reclining part so that the functional member be sealed inside the protective plate. SOLUTION: A protective plate 8 made of synthetic resin and a heating element 9 which are joined to each other are held in a molding cavity 7 of a mold tool 3a, for instance, out of mold tools 3a and 3b. After a cylindrical parison 2 is formed by extrusion by an extruder die 1, subsequently, extension pins 5a and 5b surrounded by the cylindrical parison 2 are made apart from each other in longitudinal holes 4a and 4b and thereby the cylindrical parison 2 is shaped like a flat tube. Next, the widened parison 2 is held by pinch plates 6a and 6b between and fusion-bonded. While the mold tools 3a and 3b are clamped thereafter, air is blown into the parison to bring it into close contact with the inner surfaces of the mold tools and with the protective plate 8 and the heating element 9 and the peripheral part of the protective plate 8, at least, is fusion-bonded to a seat part.

Title: Semiconductor testing device
Inventor: TANAKA KOJI
IPC: G01R31/26
Filed: 1988-12-05
Abstract: PURPOSE:To accurately measure access time by finding actual waveform characteristics and ideal waveform characteristics for each semiconductor device to be measured, and using their difference as a correcting value and measuring the access time. CONSTITUTION:When a DC measurement is taken, a relay 3c is turned on to connect a semiconductor device 1 to be measured to a DC measuring instrument 4. Here, the device 4 supplies a current I forcibly to the device 1, a voltage developed at the output pin of the device 1 is measured, and the result is sent to a CPU 6. Then the CPU 6 finds output impedance by a relational equation Z=DELTAV/I from the result. Here, DELTAV is a voltage difference and I is an applied current. Further, a decision circuit 5 measures the actual waveform of the device 1. Then the CPU 6 compares the result with the output of an ideal waveform and uses the difference as the correcting value. A correcting circuit 7 corrects the criterion of the access time measurement before correction and the criterion after the correction by using the correcting value to accurately measure the access time.

Title: Drive circuit for current drive type semiconductor switch
Inventor: MAKINOSE KOUICHI
IPC: H03K17/04
Filed: 1989-11-28
Abstract: PURPOSE:To reduce the power consumption by providing a chopper means on a constant current source and supplying a current to a base or a gate of a current drive semiconductor switch when the switch means is thrown to the position of the current drive semiconductor switch. CONSTITUTION:When a low level signal is outputted from a chopper circuit 9, a transistor(TR) Q3 is turned on and power is supplied to the load. Moreover, when a high level signal is outputted to the TR Q3, since the TR Q3 is turned off, no other current flows to a resistor RSH. However, an inductance L acts to keep a current having so far flowed and causes a current IL close to the current having so far flowed to flaw. When the loop current IL flows in this way, a TR Q2 set to ON keeps its ON state by the current. The current supplied to a base B of the Tr Q2 is a small current required to turn on the Tr Q2. Thus, the power consumed in the resistor RSH is very small.

Title: Production of thin-film magnetic head
Inventor: YAMAZAKI TAKASHI
IPC: G11B5/31
Filed: 1991-11-25
Abstract: PURPOSE:To obviate the generation of defects in a protective film by impressing a specified bias voltage to a substrate until a lower magnetic pole and a upper magnetic pole are completely coated to form the protective film and changing the bias voltage according to the progression of the formation of the protective film after the end of the coating, thereby forming the protective film. CONSTITUTION:This process for production of the thin-film magnetic head consists in forming the protective film 18 consisting of a metal oxide on the lower magnetic pole 13 and upper magnetic pole 17 formed on the substrate 11 in order to protect these magnetic poles 13, 17. The protective film 18 is formed by a bias sputtering method for impressing the specified negative bias voltage to the substrate 11 until the lower magnetic pole 13 and the upper magnetic pole 17 are completely coated. The protective film 18 is formed by using the bias sputtering method which successively changes the bias voltage according to the progression of the formation of the protective film 18 after the end of the coating. As a result, internal stresses are decreased and the generation of chipping and cracking is substantially prevented at the time of working and polishing. The presence of the defects in the protective film 18 near the magnetic pole parts 13, 17 is substantially obviated and the corrosion and damage of the magnetic pole parts 13, 17 are prevented.

Title: Deodorizing device
Inventor: YAMASHITA TSUYOSHI
IPC: B01D53/38
Filed: 1992-11-18
Abstract: PURPOSE:To obtain a deodorizing device which is capable of removing an air containing an odorous component, e.g. an odor generated from an exhaust port in a volume reduction machine of a foamable thermoplastic resin. CONSTITUTION:The deodorizing device is designed so that an air containing an odorous component is allowed to pass through a layer 2a packed with an deodorant for chemical reaction, a layer 2b packed with a deodorant for physical adsorption, and a layer 2c packed with an aromatic agent, if necessary. Consequently, it is possible to remove an odorous component which cannot be removed only by a deodorizing device consisting of a deodorant alone for chemical reaction, using a deodorant for physical desorption. Thus a variety of odorous components can be removed. In addition, the amount of the odorous component which flows into the deodorant layer for physical adsorption is small, as the majority of the odorous component is removed by chemical reaction. Therefore, the required amount of the deodorant can be minimized. Therefore, the device is lightweight and compact.

Abstract: PURPOSE:To improve braking ability and driving ability especially on an ice road by a method wherein specified discontinuous grooves are formed in a tread surface formed of a specified rubber composition to form pseudo-blocks, and cuts are formed in the pseudo-block. CONSTITUTION:The tread of a tire is formed of a rubber composition having JIS-A hardness of 58-66 at -10 deg.C. Discontinuous grooves 20 in a multirow formed such that groove parts 21 and non-groove parts 22 are alternately interconnected in the same direction are arranged in a manner to cross each other at the non-groove part 22. Namely, a number of pseudo-blocks 30 surrounded with the groove parts 21 and interconnected through the non-groove part 22 are formed. In the pseudo-block 30, thin cuts 4 in the direction of the width of the tire are formed. This constitution increases rigidity and the earthing area of the pseudo-block 30 and reduces an earthing pressure per a unit area. Thus, falling of the pseudo-block 30 can be prevented, and the edge effect of the cut 4 is ensured.
