Title: Control disc for belt retractor
Inventor: KIELWEIN THOMAS
IPC: B60R22/38
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To allow relative rotation in both directions between an inertial disc and a control disc by making the inertial disc free to rotate against the control disc and connecting it to the control disc by a sliding clutch. SOLUTION: A holding strap 30 holds an inertial disc 12 by a control disc 10 in the axial direction. Dimension of a central opening and a recessed part and dimension of a latch nose 22 and a latch strap 24 is devised so that the latch strap 24 is selected to work with the recessed part as a sliding clutch and this sliding clutch allows relative rotation of one to the other when it exceeds specified effective torque between the control disc 10 and the inertial disc 12. In such the relative rotation, the latch nose 22 and the latch strap 24 deform inward in the radial direction, and accordingly, contact between the latch strap 24 and a wall part of the opening corresponding to it can be caused.

Filed: 1989-11-22
Abstract: PURPOSE:To restrain deterioration of triboelectrifiability under high humidity by substituting N-containing functional groups at least partially -COOH groups in order to render the toner less hygroscopic under high humidity. CONSTITUTION:The colorant-containing polyester type resin has a volume average particle diameter of 4 - 10mum, and composed of diol-derived structural units and dicarboxylic acid-derived structural units, and at least a part of -COOH groups are substituted by the N-containing functional groups. The carrier particles have a weight average particle diameter of 25 - 65mum and they are prepared by coating a carrier core material with at least one of fluidity- enhancing agents in an amount of 0.05 - 10wt.% of the core weight. The absolute value of the toner to be triboelectrified with said carrier is regulated to <=20muC/g.

Title: Manufacture of semiconductor device
Inventor: OKI MASARU
IPC: H01L21/336
Filed: 1990-11-07
Abstract: PURPOSE:To prevent crystal defect and leak current, and restrain gm and Vr change, by a method wherein, in the case of forming an LDD(lightly doped drain) structure, it is selectively formed only on a gate polycrystalline silicon layer. CONSTITUTION:After an element isolation oxide film 2 and gate polycrystalline silicon 3 are formed on a P-type semiconductor substrate 1, phosphorus is ion- implanted by using the silicon layer as a mask for ion implantation, and a low concentration N-type source-drain region 4 is formed. After a polycrystalline silicon layer 5 is selectively grown on the silicon 3, a high concentration N-type source-drain region 6 is formed by using the layer 5 as a mask for ion implantation. When an LDD structure is formed, it is selectively formed only on the gate polycrystalline silicon layer. Since the LDD structure can be formed in this manner, the damage of a substrate generated when an oxide film is dry- etched, and the generation of crystal defect from the oxide film edge can be prevented. Further, leak current is eliminated and gm deterioration and Vr change can be restrained.

Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To make the distance to an object to be distance-measured computable by finding the difference of shifts of the image-forming positions on photo sensor arrays found from the amount of the shift of a standard object at the time of measuring the distance and the distance to the standard object and the amount of the shift of the object at the time of measuring the distance. SOLUTION: The distance to a standard object 1 is measured and the detected amount of shift is set a0 . A distance detecting circuit stores the preset distance y0 to the standard object 1 from an apparatus for measuring the distance to a vehicle ahead and the amount of shift a0 . The distance measurement error due to the front glass 75 is corrected using the distance y0 and the degree of shift a0 . In other words, the differences of the image-forming positions on respective photo sensor arrays due to the front glass 75 are set ΔaR, ΔaL and the amount of detected shift including the differences is set (a).  The distance (y) from the apparatus 3 for measuring distance to a vehicle ahead to an object can be defined as y=B×f/(a+Δa) where Δa=ΔaR-ΔaL (B is the distance of optical axes of respective imaging lens; f is the distance of the focuses of the respective imaging lens). Consequently, the distance (y) from the object to the apparatus 3 for measuring distance to a vehicle ahead can precisely be measured.

Title: Printer apparatus
Inventor: KIYONO KAZUYO
IPC: B41J11/48
Filed: 1987-11-30
Abstract: PURPOSE:To prevent the generation of jammings of a continuous paper in the case of an overstriking, by constructing a cutform supplying device equipped with a bail roller, in a rotatable manner with a cutform paper supplying position and a position separating from the cutform paper supplying position of the main body of a printer apparatus. CONSTITUTION:A continuous paper 36 set in a push tractor 35 is inserted much farther until it passes fully a position where a bail roller 53a of a cutform supplying device 41 is abutted with a platen 32. At this time, the continuous paper 36 is transferred to a abutted position of the bail roller with the platen 32 which position is dependent on the kind of the bail roller. Therefore, for example, if printing is to be performed overstriking onto a cutform paper 46 with the continuous paper 36 which is composed of many sheets of papers sandwiching a carbon paper therebetween, the continuous paper 36 after it is automatically loaded is transferred to the abutted position of the bail roller 53a with the platen, and pressed against the platen 32 by said bail roller 53a. Accordingly, the continuous paper 36 can be overstrikingly printed without generating jammings.

Filed: 1987-12-02
Abstract: PURPOSE:To suppress the generation of 'warpage' and to prevent the deterioration of a characteristic, even in a case of requiring heat treatment in bonding, by bonding a heat strain correction body to the surface of a substrate on the side opposite to the semiconductor light detection body bonding surface thereof. CONSTITUTION:A heat strain correction body 6 composed of a material the same to that of a semiconductor light detection body 1 of equal to said detection body 1 at least in a coefficient of thermal expansion is formed so as to have the same size as the light detection body 1 and bonded to the surface of the substrate 2 at the position opposed to the light detection body 1 so as to interpose the substrate 2. In this case, in order to prevent the release of both of them when heat stress is applied by heat treatment, a heat curable adhesive is used or an adhesive having shearing breaking strength larger than that of said adhesive is used. By this method, even if 'warpage' is ready to generate when the light detection body 1 is bonded to the substrate 2 or other heat treatment is performed, the strain in the direction opposite to the warpage is generated by the heat strain correction body 6 and both of them are negated each other to prevent or suppress the generation of 'warpage' and the deterioration of a characteristic can be prevented.

Title: Memory parity error discriminating system
Inventor: KUMAKURA HIROSHI
IPC: G06F12/16
Filed: 1988-11-30
Abstract: PURPOSE:To easily classify causes of parity errors by discriminating a parity error occurring area from a readout address on an address bus when a parity error detecting signal is received from a parity checking section. CONSTITUTION:A parity checking section 2 produces and stores a parity bit from writing data at the time of memory writing and detects a parity error (PE) by collating read-out data outputted from a memory section 1 with the parity bit produced and stored by the section 2 at the time of memory writing. A discriminating section 3 has the information of memory writing areas and, when the section 3 receives a PE detecting signal from the section 2, discriminates whether the PE occurs in a written area or unwritten area from a readout address on an address bus and outputs a hard error or program error signal to the outside. Therefore, the principal cause of the PE is discriminated easily.
