Title: Lens position controller and optical equipments using it
Inventor: SENDA AKIRA
IPC: G02B7/28
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To always perform excellent focusing operation when a focus lens group is moved by always stopping a moving lens at the middle point position of a reciprocating fine movement range or returning to the middle point position when the moving lens is shifted from the middle point position in a second mode where the focusing operation is made by manually moving the focus lens group. SOLUTION: When the moving lens 54 for wobbling is shifted from a reference position by for instance giving an impact to optical equipments, the moving lens 54 is returned to the reference position by driving a motor using a signal from a reference position detecting sensor 10 connected to the moving lens 54. A reference position signal is found out by repeatedly performing normal and reverse rotations while increasing the rotational angle of the motor little by little as a method for searching for the reference position of the moving lens. When the focusing operation is made manually, a motor holding current is made to flow through a stepping motor for driving the moving lens, so that the moving lens is not shifted from the reference position though some impact is given to the optical equipments.

Title: Method for purifying salt water
Inventor: YOSHIDA NOBORU
IPC: B01J45/00
Filed: 1992-01-10
Abstract: PURPOSE:To improve the purification efficiency by adding an aqueous solution of NaHCO3 to a crude aqueous solution of NaCl, carrying out the precise filtration and then treating the resultant filtrate with chelate resins. CONSTITUTION:An aqueous solution of NaHCO3 at 5-6wt.% concentration is added to crude salt water taken out of a raw salt dissolving vessel and the pH is regulated to 7-8. The crude salt water is then passed through a precise filter to separate and remove suspended substances in the salt water. The obtained salt water containing hardness impurities such as Ca, Sr or Mg at hundreds of ppm is subsequently passed through >=2 chelate resin columns arranged in series at a prescribed superficial velocity. The salt water regulated to slight alkalinity is primarily purified in the first chelate resin column and an aqueous solution of NaOH or Na2CO3 is added thereto according to the kind of hardness impurities in the second chelate resin column to regulate the pH of the salt water to 8-11. Thereby, secondary purification is carried out and the concentration of the hardness impurities is reduced to several ppm or below. The purified salt water is then fed to an electrolytic cell by an ion exchange membrane method. The chelate resins through which the salt water is passed are regenerated by a well-known method for use.

Title: Code conversion transmission system
Inventor: KONO OSAMU
IPC: H03M7/14
Filed: 1986-02-04
Abstract: PURPOSE:To decrease a synchronization restorating time and to simplify the circuit constitution by assigning a bit not allocated with the information of an input data signal in an n-bit code word to a synchronizing frame pattern and using the said frame pattern so as to take the frame synchronization. CONSTITUTION:In the system converting an input data signal of plural (m) bits into a code word of plural (n) bits (m<n) and sending the word, a bit not allocated with the information of the input data signal in the n-bit code word is assigned to the synchronizing frame pattern at the sending side. The frame pattern is detected at the reception side to establish the block and frame synchronization. Although (2<n>-2<m>)-set of n-bit pattern is not allocated with the information of the input data signal in the mBnB code (m<n) in general, the information is assigned as the frame synchronizing pattern in this case. Thus, the frame synchronizing circuit is simplified and the synchronization restoring time is reduced.

Title: Changeover switch for on-load tap changer
Inventor: FUKUTOME TSUTOMU
IPC: H01F29/04
Filed: 1989-02-02
Abstract: PURPOSE:To provide a changeover switch which can prevent scattering of metal powder and can be constructed in a small size by providing a power storing device for causing switching operation, a cylindrical impeller for feeding cooling gas and a filter for removing scattered metal powder. CONSTITUTION:Driving power transmitted from a pinion 2a to a spur gear 3b through an insulated shaft 4b is transferred to a pinion 2c, independently from a driving system for transmitting power to a power storing device 5. The power transmitted to the pinion 2c is transferred to a spur gear 2c directly connected therewith and thus a speed increasing mechanism is constituted. The power of the speed increasing mechanism turns a cylindrical impeller 8 fastened to an internal gear of a swing wheel bearing 7 connected thereto, whereby gas is moved in the directions as indicated by the arrows to cool a current-limiting resistor R which has generated heat during interruption of current and to lower the temperature of a resistance band to an original level. Further, metal powder produced while the device 5 including the gear mechanism is driven is removed by a filter 9 attached to the periphery of the impeller 8. During this removal of metal powder, movable vanes 8a are used in the position as indicated by the solid lines or by the broken lines in response to reversible tap changing so that the gas is moved in a constant direction and the metal powder is prevented from being scattered again.

IPC: G03G9/10
Filed: 1986-02-06
Abstract: PURPOSE:To obtain the titled developer having good fluidity and capable of forming an image having high density by incorporating a fine particle of a hydrophobic particle and a specific metal contg. bisazodyestuff in a toner, and by forming a coating layer obtd. by curing a silicone resin on the surface of a carrier particle. CONSTITUTION:The toner has the fine particle of hydrophobic silica and the metal contg. bisazodyestuff shown by the formula, and the carrier particle has the coating layer which is obtd. by curing the silicone resin on the surface of the carrier particle. As the metal contg. bisazodyestuff has a strong negative electrostatic charging property, the toner displays the good negative triboelectrifiability against the carrier having the coating layer made of the silicone resin. Thus, the toner may be charged negatively with an appropriate amount of charge by effecting friction of the toner with the carrier. As the toner contains the fine particle of the hydrophobic silica, the fluidity of the toner is remarkably improved, thereby forming the image having high density.
