Title: Wire dot head
Inventor: ARA YOUJI
IPC: B41J29/377
Filed: 1984-03-01
Abstract: PURPOSE:To arrange so that the heat radiation effect may be increased and the noise level be minimized by forming in an aluminium-zinc alloy a heat release member which constitutes a radiation fin for releasing heat generated through application of pulses to a magnet. CONSTITUTION:The pulses generated by a flexible cable 3 is applied to a coil 7 of a bobbin 8 to drive an armature 14. At that time, the heat generated by the coil 7 is transferred to a back holder 21 which is a heat release member through a core 6, a yoke 5 and a spacer 4 for radiation. This back holder 21, provided with a radiation fin, has almost an equal thermal conductivity to that of aluminium and high vibroisolating property. In addition, it is formed with aluminium- zinc alloy of high molding property which allows the forming of thin fins. Consequently, the heat release property can be enhanced. Further said alloy can be used as a material for the back holder 21, an intermediate guide 2 and a damper 18, thus reducing the head temperature by 8 deg.C and the noise level by approx. 10dB.

Title: Working oil distributing device for swash type hydraulic device
Inventor: INOUE KAZUO
IPC: F16H39/14
Filed: 1987-02-20
Abstract: PURPOSE:To reduce the size of a device, by a method wherein high and low pressure oil chambers are annularly formed so as to surround the axis of a cylinder block and be arranged in the axial direction thereof, a number of distribution valves are annularly arranged concentrically to a plunger group to the cylinder block, and a valve swash is supported to the support system of a plunger swash. CONSTITUTION:With a cylinder block 7 and a plunger swash (motor swash) 20 rotated relatively, each distribution valve 56 is reciprocated in the axial direction of the cylinder block 7 by means of a valve swash 62. A corresponding cylinder hole 18 is communicated alternately with high and low pressure oil chambers 46 and 47 to feed and receive working oil. Since a distribution valve 56 group is situated concentrically to a plunger 9 group, there is no need to increase the size of the axial direction of the cylinder block 7 in order to instal the distribution valve group and the plunger group. Besides, the valve swash 62 can be situated through utilization of a space around the plunger swash 20, and this constitution eliminates the need for increase of the size in the axial direction of a hydraulic device.

IPC: G02B6/00
Filed: 1990-02-19
Abstract: PURPOSE:To obtain the subject preform capable of production of an optical fiber excellent in transmission properties by forming a low refractive-index glass layer on the inner surface of a glass tube, subsequently depositing glass fine particles on the inside of this layer in a layer state, then carrying out dehydration and making the dehydrated glass transparent for formation of a high refractive-index glass layer. CONSTITUTION:A relatively low refractive-index glass layer 2 for the clad is formed on the inner periphery surface of a glass tube 1 using the MCVD method and glass fine particles are then deposited on the inside of the above- mentioned glass layer 2 for the clad in a layer state. The deposited glass fine particle layer is subsequently dehydrated and made transparent to form a high refractive-index glass layer 3 for the core. The glass tube 1 is then heated for formation of a solid core, thus obtaining the objective preform for an optical fiber. By using the above-mentioned, the processes for dehydration of the glass fine particle layer and for making it transparent can be carried out in an oxygen-free atmosphere when forming the glass layer 3 for the core. Accordingly the objective sufficiently dehydrated preform for an optical fiber can be produced.

Title: Heat exchanger for absorber
Inventor: ISHIBASHI TOSHIHIRO
IPC: F25B37/00
Filed: 1982-03-12
Abstract: PURPOSE:To improve the efficiency of the titled heat exchanger by a method wherein an ultrasonic resonator and an oscillator for oscillating the former are provided in the body of the heat exchanger such as an absorbing type refrigerator and the body of the heat exchanger is oscillated so that even when an absorbing solution of high viscosity is used, the amount of absorption of a coolant is increased. CONSTITUTION:In case of the absorbing type refrigerator in which the resonator 7 which forms part of an ultrasonic wave generator is attached closely to the heat exchanger 4a and which generates ultrasonic waves from the resonator 7 by receiving a signal from an oscillator connected electrically to resonator, the heat exchanger 4a which has received the ultrasonic waves repeats mechanical oscillations so that heat exchange between a thick solution concentrated by a generator 1 and a coolant is promoted and the amount of absorption of the coolant increases. Accordingly, even when the absorbing solution of high viscosity is used, no film of the solution is formed and kept remaining on the surface of a cooling coil 4a and the heat exchange efficiency is increased to thereby improve the working efficinecy of the absorbing refrigerator.

Title: Method for actuating drive unit for camera
Inventor: TOMA KIYOSHI
IPC: G02B7/09
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To increase the number of set steps of a set member to be about twice without increasing the number of steps of a motor per unit time by actuating the set member two steps each at a set actuation, stopping it by returning it by the oddnumbered steps after stopping it at a position beyond a set position when the position is the odd-nubmer-th step from the set position. SOLUTION: A diaphragm device is constituted so that the largest diameter thereof is F4 and the smallest diameter thereof is F22. At the set actuation, the set member is actuated two steps each from the first set position by the normal rotation of the motor as it is shown in a Figure. In the case a predetermined set position is the odd-number-th step from the first set psosition, the set member is stopped at the position beyond the prescribed set position. Thereafter, the motor is reversely rotated and the set member is returned by the odd-numbered steps so that the set member is stopped at the prescribed set position. Thus, the number of set steps of the set member can be made almost twice without increasing the number of steps of the motor per unit time. Besides, the number of set steps can be increased and a set time can be shortened.
