Title: Production of macrocyclic cyclodextrin mixture containing internal branched macrocyclic cyclodextrin
Inventor: KOBAYASHI SHOICHI
IPC: C12P19/20
Filed: 1992-01-29
Abstract: PURPOSE:To obtain a cyclodextrin mixture containing an internal branched macrocyclic cyclodextrin by treating cyclodextrin product with amylase and separating a branched macrocyclic cyclodextrin by a reversed phase column. CONSTITUTION:A starch is treated with a cyclodextrin(CD) synthase by a well- known method to produce a CD product. The CD product is treated with glucoamylase to produce a CD mixture containing an internal branched macrocyclic CD. The CD product is treated with glucoamylase and a branched macrocyclic cyclodextrin is separated by a reversed phase column. The macrocyclic CD mixture separated by the reversed phase column is treated with pullulanase and a straight chain saccharide is separated to give a macrocyclic CD product. The prepared macrocyclic CD mixture is made into a commodity even in this state in some uses but an ODS column is used in order to manufacture a product having a high macrocyclic CD content.

Title: Gray code counter
Inventor: ISHIZUKA HISAO
IPC: H03K21/00
Filed: 1983-03-07
Abstract: PURPOSE:To obtain a gray code counter by combining a flip-flop which is inverted during the rise of an input signal and a flip-flop which is inverted during the fall of the input signal. CONSTITUTION:A composite flip-flop circuit 10 consisting of a flip-flop 1 whose output is inverted with the rise of a signal 4 and a flip-flop 2 whose output is inverted with the fall of the signal 4 produces a 1-bit plus carry bit of a gray code counter. The circuit 10 and a composite flip-flop circuit 11 of the same constitution as the circuit 10 form a 3-bit gray code counter. The output 5 is set at 1 with the rise of the signal 4, and the output 6 is also set at 1 since the output 8 has a rise with the fall of the signal 4. The output 5 is set at 0 with the rise of the next signal, and the output 7 is set at 1 since the output 8 has a fall with the fall of the signal. The output 5 is set at 1 again with the rise of the next signal. Therefore the counter delivers the changing frequency of the input signal in the form of the gray code.

Title: Ignition timing controller of supercharged engine
Inventor: SUGIURA KATSUHIKO
IPC: F02P5/10
Filed: 1983-03-07
Abstract: PURPOSE:To improve engine performance by having the supercharged pressure act oppositely to the port pressure so as to make an ignition timing advance in case the possibility of knocking is few due to low temperature of engine water when the ignition timing is delayed by the signal of the pressure in the port adjacent to a throttle valve at the supercharging time. CONSTITUTION:If the temperature of engine water is low, that is, if the engine is being cool, a temperature sensor 23 is turned on to have a three-way change- over valve 19 communicate passages 18 and 26 with each other. The pressure in an air chamber 8 is then sent to act in a pressure chamber 16. Based on the difference between the pressures in said chamber and in the port of a pressure chamber 15, ignition timing may be controlled. In short, the ignition timing may be advanced if the temperature of engine water is low, hence improving the engine performance.

Title: Method for driving liquid crystal electrooptic element
Inventor: ITO AKIHIKO
IPC: G09G3/36
Filed: 1989-02-17
Abstract: PURPOSE:To reduce the extent of rounding of a driving waveform and to considerably improve the variance of display by mounting liquid crystal drivers on both sides of electrodes and equalizing driving waveforms inputted to the same electrode from both sides. CONSTITUTION:A left scanning driver 1 and a right scanning driver 2 are mounted for scanning electrodes 6, and an upper signal driver 3 and a lower signal driver 4 are vertically mounted for signal electrodes 5. Driving waveforms applied to the same scanning electrode 6 from left and right scanning drivers 1 and 2 are equalized. For example, equal scanning electrode waveforms 9 and 10 are simultaneously applied to the scanning electrode 6, and equal non- selecting waveforms are simultaneously applied there at the time of non- selection. Driving waveforms are applied to signal electrodes in the same manner. Thus, the extent of rounding of driving waveforms is considerably reduced though the area of a liquid crystal optical element is extended.

Abstract: PROBLEM TO BE SOLVED: To facilitate the fixing of a control terminal connecting to a control board by using a machine screw A to tighten a connection metallic fixture via a battery terminal connecting to a battery and using a machine screw B to tighten the metallic fixture via the connection terminal connecting to the control board. SOLUTION: A connection metallic fixture 15 has a through-thread to an inner cylinder formed by outsert or insert forming and whose both end faces are faced to a control board 6 and a battery chamber 8 while being penetrated through a wall 9. A machine screw A16 is tightened to the metallic fixture 15 via a battery terminal 17 connecting to the battery 14. A machine screw B18 is tightened to the metallic fixture 15 via a connection terminal 19 connecting to the control board 6 together with a seal agent 20. Thus, while the machine screw A16 is tightened to the metallic fixture 15 via the battery terminal 17 connecting to the battery 14, the machine screw B18 is fixed to the metallic fixture 15 without soldering the terminal 19 connecting to the board 6.  As a result, the locking of the terminal 19 to the metallic fixture 15 is facilitated and a danger that a wall 9 around the metallic fixture 15 is not thermally molten in mistake during soldering is avoided.

Filed: 1990-02-19
Abstract: PURPOSE: To eliminate an initial state stored in a form of charges in a capacitor of the voltage/frequency converter in a shorter time than a time required in other states by applying an additional current to an integration node. CONSTITUTION: A frequency operation circuit gives a speed-up current IS from a current source 38 to a summing node 24. A synchronization circuit 40 responds to a frequency conversion request by triggering the current source 38 and deactivating a gate circuit 36. The circuit 40 compares an input voltage from an integration device 26 with a threshold voltage Vt2 with respect to the voltage/ frequency converter to eliminate the current IS in response to detection of matching between the voltage Vt2 and a voltage integrated for an integration cycle operation thereby activating the gate circuit 36. Thus, the voltage/ frequency converter starts a complete cycle by a new frequency.
