Abstract: PURPOSE: To dispense with the removal and attachment of a spacer for reducing the adjusting operation of backlash by providing a screw part on the peripheral surface of a bearing means and forming a threaded hole engaging the crew part of the bearing means in a support member. CONSTITUTION: Fixing nuts 18c, 20c for bearing fixing members (fixing member) 18a, 29a are loosened to be rotated relative to a support member 10. Next, the fixing members 18a, 20a are rotated to be moved along the axes a1, a2. Thus, bevel gears 12, 14 together with the fixing members 18a, 20a are moved. A measuring instrument is disposed on the pitch circle of the bevel gear 14 and the bevel gears 12, 14 are shifted along the axes a1, a2 to obtain an amount of backlash. When an optimum backlash is obtained, the fixing nuts 18c, 20c of the fixing members 18a, 20a are fastened to secure the fixing members 18a, 20a fixedly to the support member 10. Thus, the bearing member is rotated in the threaded hole of the support member to continuously adjust the backlash of the bevel gear.

Title: Production of pyruvic acid
Inventor: SO MAMORU
IPC: C07C59/19
Filed: 1994-12-28
Abstract: PURPOSE: To obtain pyruvic acid useful as a pharmaceutical raw material, a synthetic intermediate, etc., at a low cost in stable quality by oxidizing lactic acid in a gas phase with oxygen in the presence of a specific iron phosphate catalyst. CONSTITUTION: Lactic acid contacts oxygen in a gas phase in the presence of an iron phosphate compound containing Fe3 (P3 O7 )2 as a main component at 150-350 deg.C under normal pressure for 0.1-10sec. Especially, βFe3 (P2 O7 )2 is suitable as the iron phosphate compound of the catalyst, since it is stable as the catalyst during the reaction and can exhibit high selectivity. During the reaction, FePO4 is slowly reduced to α-Fe3 (P2 O7 )2 , and Fe2 P2 O7 having Fe<2+> is oxidized to α-Fe3 (P2 O7 )2 . This is a new process capable of directly synthesizing pyruvic acrid from easily available lactic acid. An pyruvic acid ester is used as monomer intermediate, etc. for α-cyanoacrylate, α-acyloxyacrylate, etc., and accordingly useful in the field of plastics, fiber, pharmaceutical and perfumery.  Further, it is useful as a synthetic raw material for L-tryptophan, L-steine and L-tyrosine.

Title: Commodity supply device
Inventor: ICHIISHI KENZOU
IPC: B65G33/04
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To require no high accuracy for the assembling of a magnetic sensor which counts the commodities to be supplied and also to miniaturize the magnetic sensor. SOLUTION: A square magnetic circuit frame 24 made of a magnetic material is placed approximate to a reed switch 23 and a magnet 22 set opposite to the switch 23. The frame 24 uses a magnetic member which is folded in a square shape and touches the base of the switch 23 via one of its sides together with its opposite side set approximate to the outer side of a part where the magnet 22 of an attachment arm 21 is attached. Under such conditions, the frame 24 is positioned and fixed. In such a constitution, the magnetic flux of the magnet 22 can sufficiently flow through the frame 24 to actuate the switch 23 even though each magnet 22 faces the switch 23 with a slight shift caused by an assembling error. Thus, no malfunction is caused.

Title: Pulse signal output circuit and output method for pulse signal
Inventor: TANAKA YOUICHI
IPC: H03K23/64
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To output a pulse signal having a frequency value which is not the cumulation value of '2' and to prevent inner constitution from becoming complicated by sequentially accumulating the frequency value in an addition circuit whenever a specified clock pulse signal is inputted and providing a flip flop outputting a carry signal. SOLUTION: The flip flop 3 sequentially accumulates the frequency value which is digitized in the addition circuit 2 whenever the clock pulse signal having the frequency of 2<n+1> HZ is inputted. When the accumulated value is kept, '0' is carried to '1' at every (n+1) bits for the same number of times as the frequency value while 2<n+1> -pieces of clock pulse signals are inputted. A carry signal at the time of carrying becomes the pulse signal which is inputted to a frequency setting register 1 and which has the frequency value and the pules signal having the frequency value which is not the cumulation value of '2' can be outputted. Since the frequency value is added in the addition circuit 2, it is not unnecessary to read data from a memory and processing processes are reduced.

Title: High-voltage switch
Inventor: RICHIYAADO JIEI MAKUPAATORANDO
IPC: H01L21/8247
Filed: 1994-12-06
Abstract: PURPOSE: To accurately control the output voltage by providing an EEPROM IC 300 including a high voltage switch, a Vpp switch and a voltage regulator input circuit and reducing the need to use a p-channel MOSFET having the rated voltage higher than a specific level. CONSTITUTION: A high voltage switch 306 has its feature never to set the voltage higher than 12CV, for example, between two terminals of a p-channel MOSFET. When 24V is applied to the switch 306, a voltage divider 702 outputs a signal of about 17.1V to a node N3. When Vpp input IN has a low level, another voltage divider outputs a signal of about 12V to another node. An input transistor conducts against high input IN and grounds the relevant node. Therefore, the voltage drops among three pieces of p-channel MOSFET. Then a Vpp switch functions to keep the voltage lower than 12V even against high input IN between two terminals of the MOSFET. Thus, a voltage regulator input circuit 318 reduces the need to use the p-channel MOSFET having the rated voltage higher than 12V.

Title: Analog signal wave generator
Inventor: CHIARI FUENSHIYU
IPC: H03M1/66
Filed: 1989-12-21
Abstract: PURPOSE: To suppress the variation of an increment signal for generating an analog signal, and to generate an analog signal wave with satisfactory linearity by discriminating the size relation of the capacity values of plural input switched capacitors, and selecting the input switched capacitor having a center value from among them when a single input switched capacitor is supplied to switching. CONSTITUTION: Plural capacitors having the same nominal value are compared with each other for classifying the capacity values under the control of each switch operation of a switched capacitor circuit. At the time of generating the minimum unit V increment, the capacitor having a center value is used, and at the time of generating 3V increment, the capacitor having the center value and the capacitors having the both adjacent values are used. For example, when the increment values are V and 3V, 3V is generated by connecting three input switched capacitors C1-C3 in parallel, and V is generated by selecting optimal one from the three input switched capacitors C1-C3. Thus, the precision of the increment can be improved, and the waveform precision of an analog output signal can be improved.
