Title: Cam mechanism and sewing machine therewith
Inventor: IWATA MASANARI
IPC: D05B27/06
Filed: 1991-03-19
Abstract: PURPOSE:To obtain a simple structure cam mechanism which can transmit desired motions to several parts, respectively. CONSTITUTION:Normally, a main cam 104a is engaged with a bearing 106 while an auxiliary cam 104Ab is engaged with a bearing 107, and further the auxiliary cam B104c and flat surfaces 105d, 105e are engaged together. Accordingly, when a main shaft 101 is rotated, a rod 105 is reciprocated in directions of the arrows A, B along a cam curve. At this time, since the main cam 104a and the auxiliary cam A104b are engaged with the bearings 106, 107, respectively, the main cam 104a and the auxiliary cam A104b are prevented from jumping from a cam rolling surface. Further, since the rod 105 is rectilinearly guided, it oscillates in the directions of the arrows C, D.

IPC: G03G19/00
Filed: 1988-03-11
Abstract: PURPOSE:To safely and easily perform high-speed recording with a simple structure by forming a magnetic latent image by changing the superconductive state of a superconductive member to a normal-conductive state on a prescribed pattern. CONSTITUTION:In each ring-like superconductor 46 of a recording body 41 passed through a uniform magnetic field producing means 42, electric currents produced by electromagnetic inductance are made to flow continuously and uniform magnetic fields are produced. When the recording body 41 in such state is selectively heated on a pattern corresponding to picture signals by means of a thermal head 43, the heated superconductor 46 exceeds the critical temperature and changes to a normal-conductive state. When the temperature of the superconductor 46 drops by cooling thereafter, an electric current is made to flow through the superconductor 46 by means of the magnetic field of the adjacent unheated superconductor 46 and a latent image is formed by magnetic field inversion. By causing magnetic toner to adhere to the magnetic latent image by means of a development counter 44, a desired picture is formed. Therefore, high-speed recording can be performed stably and easily with a simple structure.

Title: Contact device
Inventor: MASUBUCHI TAKAMICHI
IPC: H01H21/00
Filed: 1993-02-22
Abstract: PURPOSE:To obtain a touch most suitable as a pad switch, such as a keyboard switch in an electronic musical instrument, by the reaction force at the operator due to a resultant force at its origin rising first to a specific value, then becoming nearly constant, resulting in good touch feel. CONSTITUTION:According as an elastic member 16 is pushed, the bend portion in a third connection wall 10h moves downward. Therefore, a portion corresponding to E form is first bent, so that the reception of force is this equivalent. Then, when the push advances a certain extent, the bend portion goes down, so that a portion corresponding to D form is bent, and thus the reaction force rapidly decreases. Accordingly the reaction force to the operator rises initially to a specific value, then becomes nearly constant.
